Joliet IL rent increase 2026 Joliet, Illinois — Will County seat and Illinois’ 3rd-largest city (~148,000; 40 miles southwest of Chicago on I-80 and I-55) — has no rent control. The Illinois Rent Control Preemption Act (765 ILCS 720, enacted 1997 as Public Act 89-567) bars all Illinois municipalities from capping rents. Joliet landlords may raise rent any amount at lease expiration. Security Deposit Return Act (765 ILCS 710): for 5+ unit buildings, return deposit within 30 days with itemized statement; penalty = 2× deposit + attorney fees. Non-payment eviction: 5-day pay-or-quit notice (735 ILCS 5/9-209); Will County Circuit Court (14 W. Jefferson St, Joliet IL 60432). Home to ExxonMobil Joliet Refinery (~2,500 workers), Amazon fulfillment hub (~5,000+ workers), CSX/Union Pacific Logistics Park Chicago (Elwood), Silver Cross Hospital (~3,500 employees), and Joliet Junior College (founded 1901 — America’s first public community college; ~16,000 students).

Joliet, Illinois — Will County seat, Illinois’ 3rd-largest city, anchor of one of the most significant logistics corridors in North America, and host to ExxonMobil’s Joliet Refinery — has no local rent control ordinance, and Illinois state law expressly prohibits one. Joliet landlords may raise rent freely at lease expiration.

Joliet landlords operate under the Illinois Security Deposit Return Act (765 ILCS 710) for 5+ unit buildings: 30-day return deadline, itemized statement with receipts for repairs over $126, and a 2× penalty for landlords who miss the deadline or fail to document deductions. Non-payment evictions require a 5-day pay-or-quit notice before filing in Will County Circuit Court.

Illinois rent control law: what Joliet landlords must know

Illinois has prohibited all municipal rent control since 1997. The Illinois Rent Control Preemption Act (765 ILCS 720/1 et seq., enacted as Public Act 89-567 by the 90th General Assembly) states that no municipality may enact, maintain, or enforce any ordinance or resolution which has the effect of controlling the amount of rent charged for leasing private residential or commercial property.

This preemption covers all 2,500+ Illinois municipalities regardless of home-rule status — including Chicago, Evanston, Joliet, Rockford, Aurora, Springfield, and every other city and village in the state. Joliet City Council has no legal authority to:

  • Cap rent increases at any percentage.
  • Establish a rent board or administrative review process.
  • Require landlords to justify rent increases.
  • Create a rent registry or annual filing requirement.

Joliet landlords may raise rent by any amount at lease expiration, with no cap, formula, or administrative approval. Month-to-month rent increases require at least 30 days’ written advance notice under contractual and common-law norms — but this is a notice requirement only, not a cap. No amount limit exists.

Legislative efforts to repeal preemption (the “Lift the Ban” coalition; HB 3202 in 2021; SB 1150 and HB 2862 in 2023) have died in committee without a floor vote. The preemption remains fully in force as of 2026.

Illinois Security Deposit Return Act (765 ILCS 710): Joliet landlords

Illinois’s Security Deposit Return Act (765 ILCS 710/5) governs security deposit handling for Illinois residential landlords who own 5 or more units — which covers virtually all Joliet apartment complexes, multi-unit buildings, and rental portfolios. Illinois imposes no cap on the deposit amount (unlike California’s 2× cap or Arizona’s 1.5× cap); Joliet market practice is typically 1–2 months’ rent.

  • Return deadline: 30 days after the tenant delivers possession of the unit. Unlike Texas or Missouri, Illinois does not require the tenant to provide a forwarding address to start the clock — possession delivery starts the 30-day period.
  • Itemized statement required for any deductions: each claimed damage must be listed separately with its dollar cost. Vague categories (“cleaning” or “repairs”) without line-item detail may not support the deduction in court.
  • Receipts required for any single repair or replacement costing more than $126 (this threshold adjusts periodically with the Consumer Price Index): attach paid receipts, or if work not yet completed, a written contractor or supplier estimate.
  • Penalty for violation: 2× the deposit + attorney fees. Missing the 30-day deadline or failing to provide adequate documentation triggers the 2× penalty automatically — no bad-faith showing is required by the tenant. On a $1,500 deposit: $3,000 in damages, plus the tenant’s attorney fees.
  • 4-unit exemption: landlords who own 4 or fewer units are NOT covered by 765 ILCS 710 — they are governed by common law only (return deposit minus documented deductions; no 2× statutory penalty).

Joliet security deposit disputes under $10,000 are heard in the Will County Circuit Court Small Claims division (14 W. Jefferson St, Joliet, IL 60432; Twelfth Judicial Circuit).

Illinois Security Deposit Interest Act (765 ILCS 730): large Joliet buildings

The Illinois Security Deposit Interest Act (765 ILCS 730/15) requires landlords to pay annual interest on security deposits held for residential tenants — but only for buildings with 25 or more units located in municipalities with a population of 25,000 or more. Joliet (population ~148,000) satisfies the population threshold, so large Joliet apartment complexes are covered.

The annual interest rate is set by the Illinois Secretary of Financial and Professional Regulation (previously the Commissioner of Savings and Residential Finance). In recent years, the mandated rate has been very low (0.01% to 0.5% range, reflecting savings account rates). The landlord must pay the interest annually (by crediting it to rent or paying the tenant directly) and provide a written statement of the amount due. Failure to pay interest allows the tenant to recover $100 plus court costs and attorney fees — a small penalty in practice given the low rates, but a compliance obligation that large complex owners should not overlook.

The Chicago RLTO (Municipal Code Ch. 5-12) has its own, more specific security deposit rules — but the Chicago RLTO applies exclusively within Chicago’s city limits and does not apply to Joliet.

Joliet eviction: the 5-day notice to pay or quit

Before a Joliet landlord may file an eviction action for non-payment of rent, Illinois law requires service of a 5-Day Notice to Pay Rent or Vacate (735 ILCS 5/9-209). Key requirements:

  • Written notice identifying the amount of rent past due and the period for which it is owed.
  • Service methods: personal delivery to the tenant; delivery to a household member 13+ at the unit; or posting on the main entry door plus mailing by certified or registered mail.
  • Cure right: the tenant may pay all past-due rent within 5 days to avoid eviction. Unlike California or Texas, the Illinois notice is strictly a pay-or-quit notice — if the tenant pays within 5 days, the landlord may not proceed.
  • Counting 5 days: the period begins the day after service; weekends and holidays are included in the count (not excluded, as in some states).

After 5 days without payment or vacating, the landlord files an Eviction Complaint in Will County Circuit Court (14 W. Jefferson St, Joliet, IL 60432; Twelfth Judicial Circuit; filing fee ~$150–$250; sheriff service ~$30–$60). Hearing is typically set 14–21 days after filing. If judgment is entered for the landlord, the tenant has a brief period to vacate before the Will County Sheriff executes an Order of Possession. Total uncontested timeline: approximately 5–8 weeks from 5-day notice to physical possession.

ExxonMobil Joliet Refinery: the south Will County energy corridor

The ExxonMobil Joliet Refinery, located in Channahon, Illinois (approximately 10 miles southwest of downtown Joliet; 2600 E. Channahon Rd, Channahon IL 60410), is one of the 10 largest petroleum refineries in the United States by crude oil processing capacity. The facility has a rated crude throughput of approximately 238,000 barrels per day, processing Canadian crude oil delivered via the Enbridge Mainline pipeline system.

The refinery produces gasoline, jet fuel, diesel, heating oil, and petrochemical feedstocks for the Midwest market. Approximately 2,000–2,500 full-time ExxonMobil employees work at the Channahon complex, supported by several hundred contract workers during turnaround (maintenance) cycles. Process engineers, instrumentation technicians, HSE specialists, and plant operators earn $80,000–$160,000+ annually — generating significant demand for quality rental housing in the southwest Joliet and Channahon–Minooka corridor (1BR market rate in that corridor: $1,050–$1,450).

Amazon & CSX/Union Pacific: the Midwest logistics hub

Joliet and Will County have emerged as one of the most important e-commerce logistics hubs in North America, anchored by Amazon’s multi-facility presence and the Logistics Park Chicago intermodal terminal at Elwood.

Amazon operates multiple large fulfillment centers, sortation centers, and delivery stations in the Joliet–Channahon– Elwood–Bolingbrook corridor. Collectively, Amazon employs an estimated 5,000–10,000+ workers in Will County, making it one of the county’s largest private employers. Amazon workers (starting wage ~$18–$22/hour as of 2026) generate significant demand for affordable rental units in the $900–$1,400 range near I-80 and Route 30.

The Logistics Park Chicago (Elwood, IL; 5 miles south of Joliet), jointly served by Union Pacific’s Global IV intermodal terminal and CSX, is one of the largest inland intermodal rail facilities in the United States — processing thousands of shipping containers per day via rail connections to both coasts. The terminal employs several thousand logistics, rail, and drayage trucking workers. Will County’s position at the junction of I-80 (the busiest east-west freight corridor in the US) and I-55 (the Chicago-to-St. Louis corridor) cements its role as a permanent logistics anchor.

Joliet rental market: 2026 submarket overview

Joliet’s rental market reflects its role as a working-class and logistics-worker city with meaningful white-collar demand from healthcare and energy sector employees, plus student demand from two four-year institutions and a large community college. Because Illinois prohibits rent control, all pricing is driven by supply, demand, and employer proximity:

  • Downtown Joliet / Heritage Corridor Metra station: $900–$1,300 for 1BR. Older housing stock; walkable to casino jobs and city amenities; Metra Heritage Corridor line provides direct access to Union Station Chicago in approximately 75 minutes.
  • East Joliet / Joliet Junior College area: $850–$1,200 for 1BR. Student-driven demand; older apartment stock; more affordable segment.
  • Near Silver Cross / New Lenox / Frankfort: $1,200–$1,700 for 1BR. Higher-income suburb; newer construction; healthcare professional demand.
  • Route 30 / I-80 (near Amazon / ExxonMobil): $1,050–$1,450 for 1BR; 2BR townhomes $1,400–$1,800. Logistics and energy worker corridor; strong mid-market demand.
  • Bolingbrook / Romeoville (north Will County): $1,100–$1,600. Near Lewis University (Romeoville) aviation program; Route 53 / I-355 commuter corridor; newer apartment construction.

Joliet Junior College: America’s first public community college

Joliet Junior College (214 N. Ottawa St, Joliet, IL 60432) was founded in 1901 as the first public community college in the United States — established as the Joliet Township High School Post-Graduate Course under the supervision of the University of Chicago’s William Rainey Harper. With approximately 16,000 enrolled students (credit and non-credit) as of 2026, JJC is among the largest community colleges in Illinois.

JJC’s student population — many of whom are local Will County residents seeking affordable vocational and transfer education — creates sustained demand for lower-cost rental units ($800–$1,200) near the main campus on Ottawa Street and the City Center Campus. University of St. Francis (500 Wilcox St, Joliet; ~3,500 students; nursing and healthcare programs; Franciscan tradition since 1920) adds additional student-driven rental demand in north-central Joliet.

Rent increase notice requirements in Joliet

Illinois state law does not specify a minimum advance notice period for residential rent increases in month-to-month tenancies. Unlike California (90-day advance notice for increases over 10% under AB 1110), Oregon (90 days statewide), or Washington (180 days for increases over 3% under HB 1217), Illinois imposes no statutory advance-notice period for rent increases. In Joliet, the notice requirement is governed entirely by the lease agreement.

Best practice for Joliet landlords raising rent on a month-to-month tenancy: provide at least 30 days’ written advance notice before the increase takes effect. This is the standard contractual norm for month-to-month modifications in Illinois. No cap applies. No reason need be stated. No administrative filing is required.

Joliet vs. Chicago: key landlord-tenant differences

Chicago and Joliet are both governed by Illinois state law, but Chicago adds a significant local layer:

  • Chicago RLTO (Municipal Code Ch. 5-12): applies only within Chicago city limits. Requires separate interest-bearing account for deposits, RLTO summary pamphlet, 12-month anti-retaliation window, lockout remedy (2× monthly rent), and heat ordinance (68°F October 1–June 1). None of this applies to Joliet.
  • Cook County Residential Tenant Landlord Ordinance (2021): applies to unincorporated Cook County and some Cook County municipalities that opted in. Will County (Joliet) is NOT covered.
  • Deposit law: in Joliet, the 765 ILCS 710 framework applies (5+ unit buildings; 30-day return; 2× penalty). In Chicago, the RLTO’s deposit rules apply to covered units (separate bank account; RLTO interest rate; 30-day return; 2× penalty; pamphlet disclosure).
  • Eviction court: Chicago evictions filed in Cook County Circuit Court (Daley Center). Joliet evictions filed in Will County Circuit Court (14 W. Jefferson St, Joliet). The Illinois Eviction Act process is the same; the court venue differs.
