The template mechanics.
The rent increase wizard asks for the current rent, the new rent, the proposed effective date, and the notice date. LeaseKit calculates the percentage increase, applies the correct Washington advance notice rule, and flags any shortfall if the effective date is too close. Rent controlled or rent stabilized units require additional compliance that the PDF calls out.
Honest limits.
LeaseKit is a document generator, built in collaboration with final year law students and developers, tailored to each state’s landlord tenant rules. For a rent increase in Washington, it assembles the clauses that belong in the document and fills in your details.
It is not a substitute for a licensed attorney on a specific dispute. Housing law changes year to year. Template content is based on publicly available rules as of early 2026. Verify the notice periods and caps against current Washington law before using the PDF for anything time sensitive.
