Missouri Rent Control Law 2026 — RSMo §441.043 statewide preemption, dual-state KCMO bi-state preemption with Kansas, no Missouri deposit cap, and the complete Kansas City + St. Louis landlord guide

RSMo §441.043 — the statute, the emergency, and the backstory

Missouri Revised Statutes §441.043 is one sentence long:

“No political subdivision of this state shall enact or enforce any ordinance or other measure to limit or control the amount of rent charged for private residential real property.”

Governor Mike Parson signed Senate Bill 26 on September 28, 2021, with an emergency clause under Article III, §29 of the Missouri Constitution. This meant the statute took immediate legal effect on the date of signature — no 90-day waiting period, no referendum window, no delayed implementation. On September 28, 2021, every rent-control ordinance in every Missouri city and county became void.

Why the emergency? The context was COVID-19 housing pressure. In 2020 and 2021, the Kansas City City Council and the St. Louis Board of Aldermen both explored emergency rent stabilization ordinances as pandemic-related eviction moratoriums began expiring. The Missouri General Assembly was watching. Senate Bill 26 moved quickly through the 2021 session under Republican supermajorities in both chambers, with the emergency clause attached to ensure it could not be circumvented by a city council acting in the window between passage and the usual 90-day effective date.

The statute covers every form of local government in Missouri: incorporated cities (first-class, second-class, third-class, fourth-class), charter municipalities (Kansas City, St. Louis, St. Joseph, Joplin, Cape Girardeau, and others), counties, townships, and special districts. “Private residential real property” is not defined narrowly: it reaches single-family rentals, duplexes, mobile homes rented on private land, rooming houses, and multi-unit apartment buildings alike. There is no exemption based on building age (unlike California’s AB 1482 which exempts construction less than 15 years old), building size, tenant income, or ownership type.

What §441.043 does not cover

RSMo §441.043 prohibits rent control — ordinances that set a maximum rent or cap increases. It does not prohibit municipalities from enacting other landlord-tenant regulations: local rental inspection programs, just-cause-for-eviction ordinances, source-of-income anti-discrimination rules, and habitability code enforcement are all still permissible under state law. As of June 2026, no major Missouri city has enacted a just-cause eviction ordinance, but the statute does not foreclose that possibility.

Nor does §441.043 affect rent on public housing (governed by federal Housing Authority rules) or federally subsidized units (Section 8 Project-Based contracts, Low-Income Housing Tax Credit income-restricted units). It is targeted specifically at market-rate private residential property.

Kansas K.S.A. §12-16,130 — the bi-state KCMO preemption

The Kansas City Metropolitan Statistical Area spans 15 counties across two states: Jackson, Clay, Platte, Cass, Ray, Lafayette, Saline, Carroll, Johnson, and Caldwell counties in Missouri; Johnson, Wyandotte, Leavenworth, Miami, and Douglas counties in Kansas. The MSA population is approximately 2.2 million people, with roughly 1.7 million on the Missouri side and 500,000 on the Kansas side.

In the same 2021 legislative session in which Missouri enacted RSMo §441.043, the Kansas Legislature enacted K.S.A. §12-16,130 (House Bill 2402, effective July 1, 2021). The Kansas statute reads:

“No city or county shall enact, adopt, maintain, continue in effect or enforce any ordinance, resolution, policy, plan, or other measure that controls the amount of rent charged for the use of privately owned residential property.”

The Kansas City metro is the only major US metropolitan area in which simultaneous rent-control preemption legislation was enacted on both sides of a state line in the same legislative year. This creates a policy clean room of unusual durability: reversing the preemption would require coordinated legislative action in two state capitols under two different political environments. Missouri has had Republican supermajorities in the General Assembly since 2010; Kansas has had Republican legislative majorities as well. Neither state has a political trajectory that suggests repeal in the near term.

Practical implications for bi-state portfolio landlords

A landlord with units on both sides of the KCMO metro faces two different landlord-tenant codes operating under the same policy outcome (no rent control):

• Missouri side (RSMo Chapters 441 and 535): no deposit cap; 30-day single-trigger deposit return; 3-day demand for non-payment; 1-month MTM notice; Detling v. Edelbrock common-law implied warranty of habitability. No URLTA.
• Kansas side (Kansas Residential Landlord and Tenant Act, KSA Chapter 58 Article 25, enacted 1975 — Kansas DID adopt a URLTA-adjacent code): 1-month deposit cap; 14-day return (14 days after tenant vacates AND provides forwarding address — dual-trigger); 3-day demand for non-payment; 30-day MTM notice; statutory implied warranty of habitability under KSA §58-2553.

The Kansas Residential Landlord and Tenant Act applies to units in Johnson County (Overland Park, Olathe, Lenexa, Shawnee, Leawood, Mission, Merriam, Prairie Village, Roeland Park), Wyandotte County (Kansas City KS, Bonner Springs), and Leavenworth County. These are governed by Johnson County District Court (150 W. Santa Fe, Olathe KS 66061) and Wyandotte County District Court (710 N. 7th St, Kansas City KS 66101), not the Missouri Circuit Courts.

Missouri landlord-tenant law — deposits, notices, and Detling v. Edelbrock

Security deposits: the unique absence of a cap

Missouri is alone among major US states in imposing no statutory maximum on residential security deposits. RSMo §535.300 governs the mechanics of deposit return but says nothing about the amount a landlord may collect. This reflects Missouri’s non-adoption of the Uniform Residential Landlord and Tenant Act (URLTA), which in URLTA states typically limits deposits to one or two months’ rent.

The practical consequence: Missouri landlords may legally require three months’ rent, four months’ rent, or any amount as a security deposit. Market practice typically runs one to two months’ rent for standard apartments. Luxury units in Clayton or the Country Club Plaza corridor may require two to three months. For tenants with credit challenges, some Missouri landlords charge non-refundable “move-in fees” in lieu of large deposits — also permissible because no Missouri statute distinguishes between refundable deposits and non-refundable fees (unlike California, which treats any amount held to cover potential damage as a refundable security deposit regardless of what it’s called).

RSMo §535.300 — deposit return mechanics

RSMo §535.050 — the 3-day demand

For non-payment of rent, Missouri law requires a 3-day written demand to pay or vacate before the landlord may file an eviction petition. The demand must describe the property, name the tenant, state the amount owed, and demand that the tenant either pay the full amount due or vacate within three days. Missouri’s 3-day demand is among the shortest in the country:

• Missouri: 3 days (no statutory cure right)
• Tennessee (Shelby/Davidson/Hamilton County URLTA): 14 days with mandatory cure right
• Wisconsin: 5 days with mandatory cure right (§704.17(3)(a))
• Michigan: 7 days (no statutory cure right)
• Indiana: 10 days (no statutory cure right)
• Ohio: 3 days (no statutory cure right; same as Missouri)

Missouri does not require the landlord to accept payment tendered after the 3-day period expires. However, as a practical matter, accepting full payment before the eviction hearing moots the non-payment claim, and most courts will deny possession if the tenant pays in full prior to the hearing date.

RSMo §441.060 — month-to-month termination

For month-to-month tenancies, either party may terminate by giving one month’s written notice before the end of the monthly rental period. Missouri’s 1-month MTM notice requirement matches Tennessee (RSMo §66-28-512 is 30 days), is shorter than Indiana’s one-rental-period notice (approximately 30 days), and longer than Ohio’s 30-day notice in practice. Missouri courts have interpreted “one month” to mean a full calendar month, not merely 30 days — a notice given on the 15th of a month typically runs to the 15th of the following month, not necessarily the end of the month.

Detling v. Edelbrock — implied warranty of habitability (Missouri common law)

Detling v. Edelbrock, 671 S.W.2d 265 (Mo. banc 1984) is the Missouri Supreme Court decision that established the implied warranty of habitability in residential leases. The Court held en banc that every residential lease contains an implied covenant that the premises are fit for human habitation at the inception of the tenancy and will be maintained in that condition throughout the lease term.

Because Missouri never adopted URLTA, the habitability warranty operates through common law rather than statute. This has several consequences for Missouri landlords:

1. No prescribed notice period: URLTA states typically require the tenant to give the landlord 14 or 30 days’ written notice before exercising habitability remedies. Missouri imposes no such prerequisite — a tenant may raise habitability as a defense to an eviction petition without any prior written notice to the landlord (though written notice creates a paper trail and is strongly advisable).
2. No codified abatement formula: Tennessee URLTA specifies that rent abatement equals the difference between the agreed rent and the rental value of the premises in their deficient condition. Missouri courts calculate abatement on a case-by-case basis with no statutory formula.
3. No repair-and-deduct right: Missouri common law does not give tenants a statutory right to repair defects and deduct the cost from rent. The repair-and-deduct right is a URLTA creation; Missouri tenants who want repairs must seek court relief rather than self-help.

Kansas City deep dive — employers, neighborhoods, and rental demand

The Kansas City MSA has a population of approximately 2.2 million people and an economy built around a cluster of uniquely Kansas City–anchored companies that are either the largest in the world at what they do or the longest-tenured at their Kansas City address. Understanding these employers explains the neighborhood-level rental demand patterns that drive the KCMO market.

Hallmark Cards — 116-year Kansas City headquarters, world’s largest greeting card company

Hallmark Cards (2501 McGee Street, Kansas City MO 64108; PRIVATELY HELD; estimated revenue approximately $2.5 billion+; approximately 22,000 employees worldwide; approximately 4,000–5,000 Kansas City headquarters employees) has been headquartered in Kansas City continuously since its founding in 1910 — 116 years as of 2026 — making it one of the longest-tenured Fortune-scale private company headquarters in any single American city.

Hallmark was founded by Joyce C. Hall, who arrived in Kansas City at age 18 in 1910 with a shoebox of picture postcards and $500 borrowed from his brother. The company grew to become the world’s largest producer and distributor of greeting cards, with approximately 1,600 card designs published annually, distribution to approximately 30,000 retail outlets, and the Crown Media subsidiary that operates Hallmark Channel and Hallmark Movies & Mysteries (now rebranded). The Hall family remains the controlling shareholder through a family trust.

Hallmark’s physical presence in Kansas City centers on Crown Center, an 85-acre mixed-use development that Hallmark constructed beginning in 1971 directly adjacent to its headquarters campus. Crown Center includes the Westin Crown Center hotel, the Sheraton Crown Center, retail and restaurant space, and the Hallmark Visitors Center. It is one of the most substantial examples of corporate placemaking in American mid-century urban development — comparable in ambition to Rockefeller Center in New York, though at a smaller scale. The Crown Center neighborhood, and the adjacent Hospital Hill district (home to Children’s Mercy and Saint Luke’s Health System), commands 1BR rents of $1,100–$1,800.

H&R Block — 71-year Kansas City headquarters, 800 million+ US tax returns

H&R Block (One H&R Block Way, Kansas City MO 64105; NYSE:HRB; approximately $3.5 billion revenue FY2024; approximately 11,000 employees; Kansas City headquarters since founding in 1955 = 71 consecutive years) is the world’s largest tax preparation company by total returns filed. The company has filed more than 800 million US tax returns since its founding — more individual US tax returns than any other entity, public or private, in American history. H&R Block was founded in Kansas City in 1955 by brothers Henry and Richard Bloch, who identified an underserved need for affordable professional tax preparation for individuals who could not afford CPAs. The company went public in 1962 (NYSE:HRB) and has remained headquartered in Kansas City for its entire 71-year existence. Its downtown campus at One H&R Block Way, near the Sprint Center (now T-Mobile Center) and the Power and Light entertainment district, supports demand in the River Market, downtown loft, and Crossroads Arts District submarkets, where 1BR rents range from $1,100–$2,000.

Oracle Health / Cerner — $28.3 billion acquisition, #2 US EHR

Oracle Health (2800 Rock Creek Pkwy, North Kansas City MO 64117; campus extends into suburban North Kansas City) was founded as Cerner Corporation in Kansas City in 1979 by three University of Missouri graduates — Neal Patterson, Cliff Illig, and Paul Gorup — who identified that healthcare was the last major US industry with no computerized medical records system. The company grew over 43 years to become the #2 US electronic health records vendor by hospital count, serving approximately 28,000 healthcare facilities worldwide including major health systems in the US, UK, Saudi Arabia, Australia, and Canada.

Oracle Corporation acquired Cerner on June 6, 2022 for $28.3 billion — one of the largest healthcare technology acquisitions in history and Oracle’s largest acquisition ever. The combined entity, now operating as Oracle Health, employs approximately 28,000 people worldwide with a substantial concentration in the North Kansas City campus. The Rock Creek campus drives rental demand in North Kansas City proper (River Market corridor, approximately $1,200–$1,600 1BR) and in the suburban Gladstone/Kearney Road corridor to the north.

Burns & McDonnell — 100% ESOP, 128-year Kansas City headquarters

Burns & McDonnell (9400 Ward Pkwy, Kansas City MO 64114; approximately $7 billion+ revenue FY2023; approximately 10,000+ employees; Kansas City headquarters since 1898 = 128 consecutive years) is one of the largest fully employee-owned engineering and construction companies in the United States. The firm converted to 100% Employee Stock Ownership Plan (ESOP) structure in 1986 and has remained wholly employee-owned since — a structure that has produced consistently high employee retention and satisfaction. Burns & McDonnell has appeared on the Fortune 100 Best Companies to Work For list for more than 20 consecutive years, one of the longest streaks of any company in the survey’s history.

The firm’s most visible recent project was the design of the new Kansas City International Airport single terminal, opened in February 2023 at a total project cost of approximately $1.5 billion — the largest public infrastructure project in Kansas City history. Burns & McDonnell’s Ward Pkwy campus in the Waldo/Brookside/Leawood submarket drives premium demand in south KCMO: Waldo 1BR rents $1,000–$1,600; Leawood KS (Johnson County) 1BR $1,400–$2,500.

Children’s Mercy Kansas City — only nationally ranked pediatric hospital in 1,000-mile corridor

Children’s Mercy Kansas City (2401 Gillham Road; approximately 9,000 employees; consistently ranked by US News & World Report in 8 clinical specialties) is the only nationally ranked academic children’s hospital between St. Louis and Denver — a geographic corridor of approximately 1,000 miles. Founded in 1897 by two women physicians, Drs. Katherine Berry Richardson and Alice Graham Berry, Children’s Mercy operates the only Level I pediatric trauma center in the region and serves as the primary children’s hospital for a five-state region (Missouri, Kansas, Nebraska, Iowa, and Oklahoma). The hospital’s location on Gillham Road in the Hospital Hill district, adjacent to the University of Kansas Medical Center campus and Crown Center, anchors the Hospital Hill submarket at $1,100–$1,800 1BR.

Kansas City Chiefs — back-to-back Super Bowl champions, 123.7 million viewers

The Kansas City Chiefs (One Arrowhead Drive, Kansas City MO 64129; Arrowhead Stadium capacity 76,416) won back-to-back Super Bowls: Super Bowl LVII on February 12, 2023 (defeating the Philadelphia Eagles 38–35 in Glendale AZ; Patrick Mahomes 182 rushing yards, 3 TD) and Super Bowl LVIII on February 11, 2024 (defeating the San Francisco 49ers 25–22 in overtime in Las Vegas; the first OT finish in Super Bowl history). Super Bowl LVIII drew an average of 123.7 million viewers on CBS, the most watched US television broadcast in recorded Nielsen history — surpassing the prior record set by the 2023 Super Bowl (113 million viewers). Patrick Mahomes has now won 3 Super Bowls and 3 NFL MVP awards as of 2026.

The Chiefs’ sustained success has driven measurable rental demand effects: the 64129 zip code (Stadium area/Longfellow neighborhood), once one of KCMO’s most distressed submarkets, has seen sustained interest from investor-buyers since 2021 in anticipation of the new Kansas City Royals downtown stadium (projected 2028) that would create a dual-stadium entertainment district adjacent to Arrowhead. Proximity to Arrowhead is now a rental marketing point in listings — a phenomenon unprecedented in Kansas City’s recent history.

Kansas City neighborhood rent table (2026)

St. Louis deep dive — employers, neighborhoods, and rental demand

St. Louis (City population approximately 285,000; County approximately 1.0 million; MSA approximately 2.8 million) is Missouri’s second major rental market and one of the most economically layered cities in the American interior. St. Louis hosts the headquarters of Boeing’s defense operations, America’s largest Medicaid managed-care company, the world’s largest broker-dealer by branch-office count, and one of the world’s most venerable industrial companies — plus the major employer anchors of its own healthcare corridor and the St. Louis Cardinals, who have won 11 World Series championships.

Boeing Defense, Space & Security — Phantom Works, F-15EX, 136-year St. Louis aviation heritage

Boeing Defense, Space & Security (3003 Boeing Drive, Berkeley MO 63134; approximately 14,000–16,000 employees in the greater St. Louis metro) is St. Louis’s largest private sector employer. The St. Louis facility is the primary production site for:

• F-15EX Eagle II — the most advanced variant of the F-15 airframe (first flight 2020; active US Air Force production as of 2026; also exported to Saudi Arabia, Qatar, Singapore, and South Korea)
• F/A-18E/F Super Hornet and EA-18G Growler — the US Navy’s primary carrier-based strike aircraft; EA-18G electronic warfare variant; also produced for Australia and Kuwait
• T-7A Red Hawk — advanced jet trainer replacing the T-38 Talon; USAF contract ~$9.2 billion; deliveries beginning 2023
• Phantom Works — Boeing’s advanced research and development division, headquartered in St. Louis; responsible for the MQ-25 Stingray unmanned refueling tanker (US Navy), SB>1 Defiant helicopter, and various classified programs

The St. Louis aviation heritage dates to 1916: McDonnell Aircraft was founded in St. Louis in 1939 by James S. McDonnell; merged with Douglas Aircraft in 1967 to form McDonnell Douglas; acquired by Boeing in 1997. The F-4 Phantom II (1958), F-15 Eagle (1972), and F/A-18 Hornet (1978) were all designed and first manufactured in St. Louis. The Spirit of St. Louis (the plane Charles Lindbergh flew in his 1927 transatlantic crossing) was not built in St. Louis but was named after the St. Louis business backers who funded the venture. Boeing’s St. Louis presence drives housing demand in Hazelwood, Bridgeton, Berkeley, and the western St. Louis County suburban corridor.

Centene Corporation — Fortune 24, America’s largest Medicaid managed-care organization

Centene Corporation (7700 Forsyth Blvd, Clayton MO 63105; NYSE:CNC; Fortune 24 FY2024; approximately $145 billion revenue FY2024; approximately 72,000+ employees worldwide) is America’s largest Medicaid managed-care organization by enrollment and revenue. Centene administers Medicaid, Medicare Advantage, and Marketplace (ACA) health insurance plans across 50 states through subsidiary brands including Sunshine Health (Florida), WellCare (multiple states), Magellan Health (behavioral health), and Ambetter (Marketplace). The company relocated its official headquarters address from St. Louis proper to Clayton, Missouri (St. Louis County) in 2020 when it completed its new headquarters tower at 7700 Forsyth Blvd in the Clayton central business district.

This relocation had a dramatic effect on Clayton rents. Clayton is already St. Louis County’s premier business address — it hosts the county government seat and the 21st Judicial Circuit Court — but the arrival of Centene’s approximately 5,000–7,000 metro-area employees in a concentrated Clayton campus drove 1BR rents in the Clayton central corridor from approximately $1,400–$1,800 in 2019 to approximately $1,800–$2,800 in 2026. The Clayton/Brentwood submarket now commands the highest rents in greater St. Louis, exceeding even the Central West End’s pre-Centene-arrival premium.

Edward Jones — world’s largest broker-dealer by branch offices, 103-year St. Louis headquarters

Edward Jones (12555 Manchester Rd, Des Peres/St. Louis MO 63131; approximately 12,000 St. Louis headquarters employees; approximately 52,000 total worldwide; approximately 19,000+ branch offices across the United States, Canada, and the United Kingdom; approximately $2.1 trillion+ in client assets; partnership structure — not publicly traded) is the world’s largest broker-dealer by number of branch offices. This is a meaningful distinction: Edward Jones’ model is one financial advisor per office, located in small towns and suburban strip malls across North America — a deliberate strategy of geographic reach over urban concentration. The firm was founded in St. Louis in 1922 by Edward D. Jones Sr. and has maintained its principal headquarters in the St. Louis suburbs for 103 consecutive years.

The Des Peres/Ladue corridor in western St. Louis County, where the Edward Jones campus is located, is one of the wealthiest suburban corridors in Missouri. Proximity to the Edward Jones campus and the adjacent west-county financial services cluster (Raymond James, Northwestern Mutual offices, independent RIAs) drives 1BR rents in the $1,200–$2,000 range in the Kirkwood/Glendale/Des Peres submarket.

Emerson Electric — 136-year Ferguson MO headquarters, Fortune ~200

Emerson Electric (8000 W. Florissant Ave, Ferguson MO 63136; NYSE:EMR; Fortune approximately 200; approximately $15 billion revenue FY2024; approximately 65,000 employees worldwide; St. Louis/Ferguson headquarters since 1890 = 136 consecutive years) is one of the longest-tenured Fortune-scale corporate headquarters in any single American city. Emerson was founded in 1890 by John Wesley Emerson as a manufacturer of electric motors, fans, and power tools; over 136 years it evolved into a diversified industrial automation and HVAC company. Major business segments include Automation Solutions (process control, measurement, industrial software) and Commercial & Residential Solutions (HVAC, refrigeration, tools). The 2023 spinoff of Copeland Corporation (formerly Emerson’s HVAC compressor and refrigeration business) reduced Emerson’s headcount but retained the Ferguson MO headquarters for the core industrial automation business. Emerson’s Ferguson campus anchors demand in the northern St. Louis County corridor (Ferguson, Florissant, Hazelwood).

Anheuser-Busch — world’s largest single-site brewery, 174-year St. Louis heritage

Anheuser-Busch (One Busch Place, St. Louis MO 63118; now AB InBev subsidiary since the $52 billion acquisition completed November 2008; Budweiser, Bud Light, Michelob Ultra, Natural Light; the St. Louis brewery complex at One Busch Place is the world’s largest single-site brewery by volume) was founded in 1852 by Eberhard Anheuser, with Adolphus Busch (who married Anheuser’s daughter and joined the company in 1864) driving its transformation into America’s dominant brewer. AB InBev, the Belgian multinational that acquired Anheuser-Busch in 2008, retained the St. Louis brewing operations and approximately 3,000–4,000 St. Louis brewery and corporate employees. The brewery complex in Soulard — covering approximately 100 acres along the Mississippi River — is a National Historic Landmark. The Clydesdales have been part of Anheuser-Busch marketing since April 7, 1933, when the Busch family presented President Franklin D. Roosevelt with a team of eight Clydesdales to celebrate the end of Prohibition. The Soulard neighborhood, immediately adjacent to the brewery, commands 1BR rents of $900–$1,700 and is one of St. Louis’s most culturally active residential neighborhoods.

BJC HealthCare — Missouri’s largest health system, Barnes-Jewish Level I Trauma

BJC HealthCare (4901 Forest Park Ave, St. Louis MO 63108; approximately 31,000 employees; Missouri’s largest health system; Barnes-Jewish Hospital Level I Trauma; Siteman Cancer Center NCI-designated; Washington University School of Medicine affiliate partner) is anchored on the Central West End’s medical campus along Forest Park Avenue — one of the most concentrated medical research corridors in the American interior. Barnes-Jewish is consistently ranked among the top 20 US hospitals nationally. Washington University School of Medicine (660 S. Euclid Ave; approximately $1 billion+ annual research expenditures; one of the top-5 ranked US medical schools) operates in direct partnership with BJC. BJC’s 31,000 employees, combined with approximately 22,000 Wash U health sciences faculty and students, drive the Central West End rental market to premium prices: $1,200–$2,200 1BR.

St. Louis Cardinals — 11 World Series championships, most in the National League

The St. Louis Cardinals (Busch Stadium, 700 Clark Ave, St. Louis MO 63102; 11 World Series championships — the most in the National League and the second-most in Major League Baseball history behind only the New York Yankees’ 27; average attendance approximately 2.8–3.0 million per year; Cardinals Nation extends approximately 500 miles across five states — Missouri, Illinois, Arkansas, Tennessee, and Indiana) are a regional institution with economics that transcend a typical sports franchise. Busch Stadium opened in 2006 and anchors the downtown Ballpark Village entertainment district, which drove substantial residential conversion and new construction in the Mill Creek Valley / downtown St. Louis corridor in the 2010s and 2020s. The Cardinals’ consistent performance and the team’s peculiarly deep regional fan base create a sustained downtown economic anchor that supports hospitality, food-service, and residential demand in the Lafayette Square, Soulard, and downtown loft submarkets.

St. Louis neighborhood rent table (2026)

Two-city rent trajectory 2019–2026

The Clayton premium is the most dramatic within-market divergence in the St. Louis MSA: the Centene HQ relocation in 2020 combined with new luxury apartment construction delivered in 2021–2023 produced the fastest sustained rent appreciation in Clayton since the post-World War II suburban build-out. By contrast, the median St. Louis city market has appreciated more modestly, constrained by population outflow (St. Louis City has lost population in most years since 2000) and a large housing stock of pre-1940 construction with higher maintenance costs.

Supply economics — why Missouri’s preemption policy matters for permit activity

The economic literature on rent control and housing supply is unambiguous in direction. The landmark study is Diamond, McQuade, and Qian (American Economic Review, 2019), which used the random assignment of San Francisco rent control coverage to measure the causal effect of rent control on housing supply. Key finding: San Francisco rent control reduced rental housing supply by approximately 15% over the long run, as landlords converted controlled units to condominiums, repurposed buildings to commercial use, or allowed units to deteriorate until they qualified for Costa-Hawkins exemption. Landlords in uncontrolled buildings — newly eligible for market-rate rents — responded by raising rents 5–7% above what they would have charged in the absence of rent control in the adjacent market, producing a citywide gentrification effect that is the opposite of what rent control advocates intended.

The Minneapolis natural experiment, operating at a shorter time scale, provides additional evidence. Minneapolis enacted Chapter 244 rent regulation effective May 1, 2022 — 3% annual cap, hard vacancy control (market reset on tenant turnover forbidden), applying to approximately 40,000+ units built before 1978. Multifamily building permits in Minneapolis fell approximately 50% in the year following enactment, the steepest documented permit decline in a major US city following rent control adoption. (Saint Paul enacted Chapter 193A simultaneously; Saint Paul’s 0% vacancy-decontrol variant — even stricter than Minneapolis’ — produced a similar permit collapse. Both Minneapolis and Saint Paul subsequently amended their ordinances to restore some vacancy-decontrol provisions after developer litigation and permit collapse data became public.)

Missouri avoided this supply constraint by enacting RSMo §441.043 preemptively. Kansas City issued approximately 4,000–5,000 new multifamily permits annually from 2022 through 2025; the Crossroads Arts District, River Market, and Westport corridors saw significant new supply delivered. St. Louis permitted approximately 2,000–3,000 units annually in the same period, with Clayton and the Forest Park SE corridor absorbing most of the luxury deliveries. Market vacancy rates in both metros remained in the 4–6% range through 2025–2026, dampening the rent-growth acceleration that characterizes supply-constrained markets. Missouri landlords are the direct beneficiaries of this policy environment: rising rents from demand growth, without the supply suppression that magnifies rent increases in controlled markets.

For a direct contrast, see our analysis of Minneapolis’ hard vacancy control and its documented permit-collapse effects, and our Illinois 765 ILCS 720 guide covering Chicago’s similar preemption framework (enacted 1997, 26 years earlier than Missouri’s).

Missouri vs. 7 other states — comparison table

Missouri’s no-deposit-cap framework stands apart from every state in this comparison. It is also notable that Missouri is the only state in this table that neither adopted URLTA nor enacted a named preemption statute before 2020 — yet ended up with one of the most comprehensive preemption statutes in the country (RSMo §441.043) by 2021. Indiana and Ohio, which rely on Dillon’s Rule rather than named statutes, face a theoretically higher risk of a future court or legislature altering their preemptive framework than Missouri, which has explicit statutory text. See also our Indiana Dillon’s Rule explainer for a detailed comparison.

8-step Missouri compliance checklist for landlords (2026)

1. Confirm statewide preemption covers your unit. RSMo §441.043 applies to all private residential real property in Missouri — apartments, single-family homes, duplexes, mobile homes on private land. No unit type is exempt. If your unit is on the Kansas side of the KCMO metro, K.S.A. §12-16,130 provides identical preemption under Kansas law. There is no rent-control ordinance in any Missouri city or county as of June 2026.
2. Set your deposit at any amount — but document it. Missouri imposes no statutory cap on security deposits. The lease must state the deposit amount clearly. If you require an amount above market norms (e.g., three months’ rent), document the business reason (credit score, prior eviction history) in the tenant file. Non-refundable fees are permissible in Missouri; label them explicitly as “non-refundable” in the lease and do not commingle with the refundable security deposit.
3. Hold the deposit in a separate account (best practice). RSMo §535.300 does not expressly require escrow; however, Missouri courts have found that commingling deposits with operating funds (and then being unable to return them) may be evidence of wrongful withholding. Use a separate checking or savings account labeled “Security Deposit Account.”
4. Return deposit within 30 days of vacancy with itemized statement. RSMo §535.300 sets a hard 30-day single-trigger deadline from the date the tenant vacates. Mail the itemized statement and any remaining deposit balance by first-class mail to the tenant’s last known forwarding address. Keep the certified-mail receipt. Failure to return within 30 days, or making deductions without an itemized statement, exposes you to a 2× wrongful-withholding penalty.
5. For non-payment: serve a written 3-day demand first. RSMo §535.050 requires a written demand to pay or vacate within three days before you file an eviction petition. The demand must: identify the property, name the tenant, state the amount of unpaid rent, and require the tenant to pay or vacate within three days. Serve by posting on the door and/or personal service; certified mail is advisable but not required by statute. Courts will dismiss an eviction petition filed without the prior demand.
6. For MTM termination: provide one month’s written notice. RSMo §441.060 requires one month’s notice for month-to-month termination. Give notice in writing, delivered or mailed, at least one full calendar month before the desired termination date.
7. Maintain habitability — respond to written complaints promptly. Detling v. Edelbrock (Mo. banc 1984) established an implied warranty of habitability. Missouri courts interpret it as requiring functional heating, plumbing, structural integrity, and compliance with applicable housing codes. Document all repair requests and completed repairs with dates, invoices, and photos. Anti-retaliation: do not raise rent, terminate a lease, or reduce services within 90 days of a tenant asserting habitability rights (Missouri common-law anti-retaliation).
8. File at the correct court. Landlord-tenant cases in Jackson County go to Jackson County Circuit Court, 415 E 12th St, Kansas City MO 64106; 16th Judicial Circuit, Associate Division. In St. Louis City: 22nd Judicial Circuit, 10 N. Tucker Blvd, Housing Court Room 133. In St. Louis County: 21st Judicial Circuit, 105 S. Central Ave, Clayton MO 63105. In Kansas-side KCMO units: Johnson County District Court, 150 W. Santa Fe, Olathe KS 66061 (governed by Kansas law, not Missouri law).
