Washington Rent Increase Calculator

Use this calculator to estimate the maximum legal rent increase for a covered rental unit in Washington. The calculation uses the rent-cap rules available in RentCheckMe's public rule data and may ask for follow-up facts when coverage depends on the property.

How the calculator works

Enter the city and current monthly rent. If the rule needs more facts, such as year built or property type, the calculator will ask for only those details before recomputing the result.
