Does Washington limit rent increases?
Washington is one of the few states with a statewide limit on rent increases: 7% + CPI, max 10%.
HB 1217 (effective May 7, 2025): annual increases capped at 7% plus CPI, maximum 10%. Published 2026 cap: 9.683%. Manufactured homes: 5% with no expiration. Exemptions: new construction under 12 years, public and low-income housing, owner-occupied two-to-four-unit buildings. Ninety-day notice required for increases.
What about city and county rules in Washington?
Before raising rent in Washington, check your city and county housing rules. Local rent stabilization programs are far more common than state caps — hundreds of US cities run their own — and they apply even where the state sets no limit. Search your city or county housing department’s website for “rent stabilization” or “rent registry,” and read the ordinance itself rather than a summary.
Exemptions: does the cap cover your property?
Rent caps almost never cover every rental unit. Common exemptions include newer construction, single-family homes, owner-occupied small buildings, and subsidized housing — but the exact list is different in every Washington jurisdiction that has a cap. Confirm whether your specific property is covered before applying any limit; an exemption wrongly assumed is as costly as a cap wrongly ignored.
Even where no Washington cap applies, remember the second half of a legal rent increase: proper advance notice. The required notice period varies by state and sometimes by the size of the increase — use our notice period calculator to date yours correctly.

Frequently asked questions
Does Washington have rent control?
Statewide, Washington limits annual rent increases to 7% + CPI, max 10%. Exemptions are common — newer buildings, single-family homes, and owner-occupied small properties are frequently excluded — so verify whether your unit is covered.
What is the maximum rent increase allowed in Washington?
The statewide formula is 7% + CPI, max 10%, under Wash. HB 1217 (2025); RCW 59.18.700–.710; WA Dept. of Commerce 2026 guidance. Published annual figures can change year to year (agencies update them), so confirm the current year’s number before calculating — the checker above applies the ceiling from our data.
Can my city limit rent increases if Washington does not?
Often yes. Many cities and counties run rent regulation programs regardless of state law. Because the answer depends on both state and local law, verify both before serving an increase.
Do rent-cap exemptions apply to my rental property?
Possibly — caps commonly exempt new construction, single-family homes, owner-occupied small buildings, and subsidized housing. Exemptions are fact-specific: verify your property’s status against the actual statute rather than assuming you qualify.
