Tacoma rent control 2026 Washington HB 1217 (RCW §59.18.700): 2026 cap 9.683% (7% + 2.683% Seattle-Tacoma-Bellevue CPI-U) — same rate as Seattle. Prescribed Commerce form required; void if non-conforming. First-year protection: no increase in first 12 months of any tenancy. 12-year rolling exemption. Larger share of older housing stock than Seattle → more buildings covered. JBLM military off-base housing market. Pierce County Superior Court for enforcement. Cap sunsets July 1, 2040.

Tacoma’s 2026 cap: HB 1217 formula and the Seattle-Tacoma-Bellevue CPI-U

Under RCW §59.18.700, the maximum annual rent increase for a covered Tacoma residential rental unit is the lesser of:

1. 7.0% plus the percentage change in the Consumer Price Index for All Urban Consumers (CPI-U) for the Seattle-Tacoma-Bellevue, WA Metropolitan Statistical Area, All Items, for the 12-month period ending June 30 of the prior year (RCW §59.18.700(2)(b)); OR
2. 10.0% absolute ceiling.

For 2026, the Seattle-Tacoma-Bellevue MSA CPI-U for June 2024–June 2025 was approximately 2.683%. Calculation: 7% + 2.683% = 9.683%, below the 10% ceiling. Tacoma’s 2026 HB 1217 residential rent cap is 9.683%.

Why Tacoma and Seattle have the same cap: HB 1217 uses a single CPI series for all of Washington — the Seattle-Tacoma-Bellevue MSA CPI-U. There is no Tacoma-specific CPI adjustment, no Pierce County geographic factor, and no local supplement or reduction. A covered residential unit in downtown Tacoma, a house in Lakewood adjacent to JBLM, an apartment in Tacoma’s Hilltop neighborhood, and a covered unit in Spokane 300 miles to the east all have the same 9.683% cap for 2026. The CPI name “Seattle-Tacoma-Bellevue” reflects that Tacoma is formally part of the MSA used to compute the index, not that Tacoma receives a different rate.

On a $1,500/month Tacoma rent (a realistic one-bedroom in the current market), the 9.683% cap allows a maximum lawful annual increase of $145.25/month. At $1,800/month (moderate two-bedroom), the cap allows $174.29/month. These figures represent the ceiling — landlords may increase by any amount at or below this ceiling, within the framework’s other constraints (prescribed form, first-year protection, once-per-12-months).

Washington’s 1981 preemption and why Tacoma had no local rent control for 43 years

RCW §35.21.830, enacted in 1981 during Washington’s legislative session, prohibited any city or county in Washington from enacting, maintaining, or enforcing an ordinance that regulates the amount of rent charged for privately owned residential housing units. This preemption was comprehensive — it applied to all Washington municipalities, including Tacoma, Seattle, Spokane, Bellevue, and every other city and county regardless of size, politics, or housing market conditions.

The 1981 preemption came during a national backlash against local rent control, following the first wave of city-level rent stabilization ordinances in the late 1970s (including California’s major cities). Washington’s legislature acted pre-emptively, before any Washington city had enacted a local RSO, blocking the trend at the state level.

For 43 years, from 1981 to 2024, no Washington city could regulate residential rents. Tacoma’s City Council and tenant advocacy groups repeatedly called for state action on rent stabilization but were legally blocked from acting locally. When Seattle City Council members introduced local rent stabilization proposals, state preemption was raised as a per se bar. When Tacoma landlords raised rents 20–40% during the 2016–2019 Seattle spillover wave and again during the 2021–2022 post-COVID surge, tenants had no local administrative recourse and no state-level cap.

HB 1217 (2024) was the legislative response: a state-enacted cap that circumvented the preemption issue because the preemption only blocked local government rent control — the state could regulate rent at the state level without violating its own preemption law. HB 1217 took effect immediately upon enactment and established the 9.683% (for 2026) cap that now governs Tacoma rentals.

HB 1217 framework applied to Tacoma: the four key features

HB 1217’s four structurally distinctive features — the 12-year rolling exemption, the first-year protection, the prescribed Commerce form, and the 2040 sunset — all apply to Tacoma in exactly the same way they apply to Seattle. The Tacoma context for each:

1. 12-year rolling new-construction exemption

Under RCW §59.18.700(2)(d), units in buildings that received their first certificate of occupancy within the prior 12 years are exempt from the 9.683% cap. For 2026, buildings completed in or after approximately 2014 are exempt.

Tacoma’s older housing stock means more buildings are covered than in Seattle. Tacoma developed its residential core in the late 1800s through the mid-20th century — the Stadium District, North End, Proctor District, Hilltop, and most of the South End were built primarily between 1900 and 1970. Tacoma did not experience the same post-2014 apartment construction boom as Seattle (which added tens of thousands of new units from 2015–2023 in neighborhoods like South Lake Union, Capitol Hill, and Belltown). As a result, a larger share of Tacoma’s rental housing stock is in pre-2014 buildings that are fully covered by the 9.683% cap.

2. First-year protection (RCW §59.18.700(1)(c))

No rent increase may be imposed during the first 12 months of any tenancy in Washington. This applies to all residential tenancies, including those in buildings that are exempt from the cap under the 12-year new-construction exemption.

Tacoma JBLM context: a JBLM service member who moves into a new Tacoma apartment (even a brand-new 2024 building) is protected from any rent increase during the first 12 months of their tenancy, regardless of the building’s age. This is especially significant in the military rental market, where landlords sometimes attempt to increase rents at the start of a new calendar year (January) without accounting for the individual tenant’s tenancy start date.

3. Mandatory prescribed Commerce form

Every rent increase notice for a covered Tacoma residential unit must use the Washington State Department of Commerce’s prescribed notice form. A non-conforming notice — one that does not use the Commerce form or that deviates from its required content — is void under RCW §59.18.700 and has no legal effect.

What this means for Tacoma landlords in practice: small independent Tacoma landlords who use property management software, generic Washington State lease templates, or CAR-style forms for rent increase notices must verify that their notice form is the current Commerce Department prescribed form. Using the wrong form — even a well-intentioned form that accurately states the new rent amount and effective date — makes the notice void. The landlord must re-serve using the correct form and restart the notice period. A voided notice does not trigger the rent increase and does not count toward the once-per-12-months frequency limit.

The prescribed-form requirement is unique to Washington among all U.S. rent-cap regimes. California AB 1482, Oregon SB 611, and Montgomery County Bill 15-23 all permit landlord-authored notices that meet content requirements. Washington HB 1217 requires the specific Commerce form, full stop.

4. Sunset provision (RCW §59.18.700(8))

The HB 1217 residential rent cap is scheduled to expire on July 1, 2040 unless the Washington legislature acts to extend or make it permanent. The 2040 sunset is unique among U.S. rent-cap regimes — Oregon SB 611, California AB 1482, and Montgomery County Bill 15-23 have no statutory sunsets. After July 1, 2040, Tacoma (and all other Washington cities) would revert to having no rent cap absent further legislative action. The sunset was a political compromise in HB 1217’s passage — moderate legislators were willing to support a cap only if it was explicitly temporary.

Note: the 5% manufactured home park cap under RCW §59.20.120 does not have a sunset provision. Tacoma manufactured home park residents are subject to the 5% cap with no 2040 expiration.

Tacoma neighborhood guide: building-age analysis and HB 1217 coverage

Tacoma’s residential neighborhoods vary significantly by era of development, and the 12-year rolling exemption (pre/post-2014 first CoC) determines HB 1217 coverage for each building. The building’s first CoC date is verifiable through the City of Tacoma Development & Permitting Services or Pierce County Assessor records.

Historic and older Tacoma neighborhoods (pre-1995 and pre-2014, HB 1217-covered)

Tacoma’s oldest residential neighborhoods contain extensive housing stock from the 1890s through the 1960s. Virtually all of this stock predates the 2014 threshold and is HB 1217-covered at 9.683% for 2026:

• Stadium District — one of Tacoma’s premier historic neighborhoods; Victorian, Craftsman, and Colonial Revival homes primarily from the 1890s–1910s era; many large homes converted to multi-unit rentals and rooming houses; Tacoma’s Stadium High School (made famous by the film “10 Things I Hate About You”) anchors the neighborhood; virtually all residential stock pre-1960; fully HB 1217-covered
• North End — Tacoma’s upscale historic residential district with large Craftsman bungalows, Tudor Revivals, and Colonial homes from the 1910s–1940s; some single-family investor rentals; HB 1217-covered
• Proctor District — classic mid-century neighborhood adjacent to North End; 1920s–1950s bungalows and apartment buildings; HB 1217-covered
• Hilltop — historically lower-income neighborhood undergoing rapid gentrification; dense apartment buildings from the 1960s–1990s; significant population of low-income tenants; much of the older stock is HB 1217-covered; newer developments on formerly vacant or demolished parcels may be post-2014 and exempt
• Central District / 6th Avenue — walkable commercial corridor with mixed-era apartments and small multifamily buildings; pre-2014 stock is HB 1217-covered
• South End / South Tacoma — working-class neighborhood with significant 1940s–1980s apartment stock; JBLM-adjacent; largely HB 1217-covered
• Eastside Tacoma — 1950s–1980s suburban apartment complexes; HB 1217-covered
• McKinley Hill / Lincoln District — older residential areas with 1950s–1970s housing; HB 1217-covered

Mid-era Tacoma (1990s–2014, HB 1217-covered)

Buildings completed between 1990 and approximately 2014 predate the 12-year rolling exemption threshold for 2026. This includes much of Tacoma’s apartment development from the 1990s housing boom and the post-2000 urban-infill period:

• Tacoma Downtown (older stock) — commercial-to-residential loft conversions and apartment buildings from the 1990s–2005 era; HB 1217-covered
• University District (near UW Tacoma) — urban campus area; mid-era apartment buildings from 1995–2013; HB 1217-covered for pre-2014 stock
• Ruston / Point Defiance adjacent — waterfront residential areas with 1990s–2000s development; pre-2014 stock is HB 1217-covered

Post-2014 Tacoma (12-year rolling exempt)

Buildings in Tacoma that received their first CoC in or after approximately 2014 are exempt from the 9.683% HB 1217 cap under the 12-year rolling new-construction exemption. Note: these buildings’ tenants still receive the first-year protection under RCW §59.18.700(1)(c) for each new tenancy.

• Downtown Tacoma — new towers: newer apartment buildings along Pacific Avenue and in the Foss Waterway District, built from 2016 onward; many post-2014 and exempt
• Hilltop — new development parcels: new construction on formerly vacant or recently demolished lots; post-2014 CoC; exempt from cap (but first-year protection still applies)
• University District (new construction): newer purpose-built student housing and mixed-use buildings adjacent to UW Tacoma; post-2014; exempt
• Lakewood — newer complexes: JBLM-adjacent Lakewood has seen new apartment development in the 2015–2024 period; post-2014 buildings near the Lakewood Towne Center and I-5/SR-512 corridor are exempt

JBLM and the Tacoma military housing market

Joint Base Lewis-McChord (JBLM) is one of the largest and most strategically important military installations in the United States, hosting the Army’s I Corps (Washington-based rapid-deployment corps) and the Air Force’s 62nd Airlift Wing. Key facts about JBLM’s impact on Pierce County housing:

• Scale: approximately 40,000 active-duty military personnel assigned to JBLM; adding family members, civilian employees, and contractors, the total JBLM- connected population in Pierce County is estimated at over 100,000 people
• On-base housing: JBLM has significant on-base family housing managed by Lend Lease and other contractors, but available on-base units are insufficient for all personnel with dependents. Waitlists for on-base housing often run 6–18 months. Most service members with families live off-base in Tacoma, Lakewood, University Place, DuPont, Spanaway, Bonney Lake, and surrounding Pierce County communities.
• Rental market impact: JBLM creates a large, relatively inelastic demand for rental housing in the Tacoma-Lakewood corridor. Service members typically rent for 2–3 years between PCS moves, creating high turnover. Landlords near JBLM have historically charged premium rents knowing that BAH (Basic Allowance for Housing) rates provide a relatively stable payment floor. 2020–2023 saw JBLM-adjacent rents surge significantly as both civilian spillover from Seattle and military BAH rate adjustments drove demand.
• BAH and HB 1217 interaction: BAH is set by the Department of Defense based on local rental market data and is intended to cover median local housing costs. When rents increase above the HB 1217 cap, landlords targeting military tenants may attempt to justify the over-cap increase by noting that BAH rates have increased. BAH rate adjustments by DoD are irrelevant to HB 1217 compliance — the cap applies regardless of the tenant’s income source or BAH entitlement. A JBLM tenant receiving BAH has the same HB 1217 protections as a civilian tenant.

SCRA and HB 1217 in parallel: JBLM-area military tenants in covered Tacoma rental housing operate under both frameworks simultaneously:

• HB 1217 (RCW §59.18.700): 9.683% cap for 2026; prescribed form required; first-year protection; penalties under RCW §59.18.730
• SCRA (50 U.S.C. §3955): active-duty service members may terminate a residential lease on 30 days’ written notice after receiving PCS orders or deployment orders of 90+ days. The SCRA termination right operates independently of HB 1217 — a service member terminating under SCRA is not subject to any early-termination penalty in the lease.

Military tenants with HB 1217 violations should contact the JBLM Legal Assistance Office (Soldier Legal Services) for integrated SCRA and HB 1217 advice. Civilian legal aid for Pierce County tenants is available through Columbia Legal Services and Tacoma-Pierce County Volunteer Lawyers Program.

The prescribed Commerce form: Tacoma landlord compliance guide

The prescribed-form requirement is the most operationally complex aspect of HB 1217 for Tacoma landlords, particularly small independent owners who have historically used generic Washington State lease addenda or property management software templates for rent increase notices.

What the Commerce form must include: the prescribed form promulgated by the Washington State Department of Commerce contains:

• Tenant name(s) and rental address
• Current rent amount
• New rent amount
• Effective date of the increase (which must be at least 180 days from the date of service under RCW §59.18.700(1)(b))
• Calculation showing the increase does not exceed the applicable cap (or a statement that the unit is exempt and the increase is above-cap for exempt units)
• Landlord name and contact information
• Tenant rights information as specified by the Department of Commerce

Wait — 180-day notice requirement? Yes. RCW §59.18.700(1)(b) requires that the notice of rent increase be served at least 180 days before the effective date of the increase. This is significantly longer than California’s 30/90-day notice requirements and longer than Oregon SB 611’s 90-day requirement. A Tacoma landlord who wants to increase rent effective January 1, 2027 must serve the prescribed Commerce form notice no later than approximately July 5, 2026. Failure to serve 180 days in advance means the notice is void as to timing even if the form itself is correct.

The graduation-day prescribed-form transition: when a Tacoma building’s 12-year rolling exemption expires (i.e., the building “graduates” from the exempt cohort to the covered cohort as 12 years pass from its first CoC), the landlord must immediately begin using the prescribed Commerce form for any future rent increase notices. The most operationally complex scenario is a building that was pre-exempt (post-2014 first CoC) and is now graduating into coverage (first CoC in or around 2014, graduating in or around 2026). Notices served before graduation without the prescribed form are void once the building is in coverage.

Notice requirements for Tacoma rent increases: the 180-day rule

HB 1217’s notice framework differs significantly from California’s:

• Minimum notice period: RCW §59.18.700(1)(b) requires at least 180 days’ advance written notice before the effective date of any rent increase in a covered unit. This applies regardless of the size of the increase — there is no Washington equivalent of California’s 30-day/90-day split.
• Prescribed form: notice must use the Washington Commerce Department’s prescribed form; non-conforming notices are void
• Once-per-12-months: only one rent increase notice may be served in any 12-month period (RCW §59.18.700(1)(a))
• First-year protection: no rent increase during the first 12 months of any tenancy (RCW §59.18.700(1)(c)), regardless of building age
• Mail and electronic service: under RCW §59.12.040, mailed notices add 3 days for service by first-class mail (not 5 days as in California). Electronic service is permitted if the tenant has agreed to receive notices electronically under the lease.

Practical example for Tacoma landlords: to serve a rent increase effective September 1, 2026, the landlord must serve the prescribed Commerce form notice by approximately March 5, 2026 (180 days before September 1). If the tenant moved in on April 1, 2026, the first-year protection bars any increase until April 1, 2027 regardless of notice timing.

Penalty framework under RCW §59.18.730

HB 1217’s penalty framework under RCW §59.18.730 is the strongest of any U.S. rent-cap regime:

• Rent reduction to the lawful capped rate
• Restitution of all unlawfully collected rent above the cap
• Up to 3× monthly unlawful rent amount (treble-damages equivalent), not to exceed 3 months of the unlawful rent
• Attorney fees and court costs to a prevailing tenant
• Civil penalties up to $7,500 per violation — unique to Washington; no other U.S. rent-cap regime has this per-violation civil penalty provision
• Washington State Attorney General parens patriae enforcement — the AG may bring a civil action on behalf of a class of affected tenants statewide; AG enforcement does not require individual tenants to initiate suits

For Tacoma matters, civil actions are filed in Pierce County Superior Court (930 Tacoma Avenue South, Tacoma, WA 98402). The AG enforcement authority operates statewide from the Office of the Washington State Attorney General, and the AG may pursue claims affecting Tacoma tenants without filing individually in Pierce County.

Void-notice consequence: a void rent increase notice (served on a non-Commerce form) has no legal effect. If a landlord attempts to collect rent above the old rate based on a void notice, that collection is unlawful, and each monthly collection of the above-cap amount constitutes a separate violation. In a building with 20 covered units where the landlord served void notices to all tenants and collected over-cap rents for 6 months, the civil penalty exposure is potentially $7,500 × 20 units × 6 months = $900,000 in civil penalties alone, plus treble damages, attorney fees, and restitution.

Tacoma versus Seattle: how the same HB 1217 cap plays differently

The same 9.683% HB 1217 cap produces different real-world outcomes in Tacoma vs. Seattle because of fundamental differences in the two cities’ rental markets:

• Rent levels: median Tacoma rents are substantially lower than Seattle. A 1-bedroom in Tacoma averages approximately $1,400–$1,600/month (2026 market); a comparable Seattle 1-bedroom averages $1,800–$2,200/month. The same 9.683% cap allows a higher absolute dollar increase in Seattle (≈$174–$213/month) than in Tacoma (≈$135–$155/month). Tenants in both cities face the same percentage cap, but the cost of a cap-maximum increase in absolute terms is lower in Tacoma.
• Housing stock age: Tacoma’s pre-2014 housing stock is proportionally larger than Seattle’s because Seattle experienced a massive apartment construction boom from 2015–2023 that added more post-2014 units to its stock. More of Tacoma’s rental market is in the covered (pre-2014) cohort.
• Military housing concentration: Seattle has limited military presence; Tacoma has JBLM, creating a unique rental market dynamic with high turnover, BAH-driven pricing, and an overlay of SCRA protections.
• Court jurisdiction: HB 1217 enforcement in Tacoma is through Pierce County Superior Court, not King County Superior Court (which handles Seattle matters). Different court, different judges, different timeline and docket conditions — but the same substantive law.
• Gentrification pressure: Tacoma’s Hilltop and other inner-city neighborhoods are experiencing active gentrification as Seattle-area workers seek lower-cost housing. This puts upward rent pressure on Tacoma’s older covered stock and raises the compliance stakes for HB 1217.
