For 2026, the Washington standard rent limit checked by RentCap is 9.683%. Kennewick properties follow the statewide path covered by RentCap rather than a Puget Sound city overlay. The calculator applies the Washington statewide rules and does not invent a separate Kennewick rent cap.

Landlord next step
Check before you deliver
Enter the actual property and tenancy facts rather than assuming that a Kennewick address changes the statewide limit. The result keeps uncertain exemption or delivery facts visible instead of treating them as a pass.
Renter next step
Use the notice exactly as written
Compare the amount, effective date, and delivery method on the notice with the Washington findings. If the notice claims a city rule or exemption, ask for the official source and supporting facts.
What to enter
Use the current rent, proposed rent, actual or planned delivery date, delivery method, kind of home, rental agreement, and any property-exemption facts you know. It is fine to mark difficult facts as unknown.

Kennewick amount check
The amount check starts with the current monthly rent and the proposed new rent. RentCap calculates the percentage increase, compares it with the published Washington limit, and keeps exemption questions separate so a missing fact does not look like a clean pass.
Kennewick timing check
Washington notice timing and service rules decide the earliest supported effective date. The checker also aligns monthly increases to the rent-period start day entered in the form, because a day-count minimum can land mid-cycle.
City rules
RentCap has not identified a separate Kennewick rent-increase percentage or notice overlay in the official sources reviewed for this page. The Washington rules still apply, and newly adopted local rules should be checked before a notice is served. ZIP code is used as a backup for the cities RentCap covers, which helps avoid a wrong answer when the city name is misspelled or abbreviated.
