Landlord next step
Check before you deliver
Enter the actual increase: the Kirkland notice period depend on the percentage. The result shows when a slightly smaller increase would need less notice.
Renter next step
Use the notice exactly as written
Compare the notice's delivery date and effective date with Kirkland's notice period. The result separates the state limit from the city rule.
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.

Kirkland 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.
Kirkland 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
Kirkland requires 120 days' notice for increases above 3% and 180 days above 10%. RentCap checked this rule against official summaries; confirm the current code text before relying on it. 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.
