Never miss a Seattle deadline.
Always know exactly which official form to use, and when.
GiveProperNotice turns your lease facts into a deadline calendar for Seattle and Washington landlords, with a statutory citation behind every date and a link to the official government form. We never draft your notice. That's the point: you stay in control, and every step traces back to a public source you can verify.

The stakes
Up to $7,500 per violation under state law, plus $500 per day for a lapsed Seattle registration.
Washington's rent-cap and notice statutes let the state Attorney General seek civil penalties of up to $7,500 per violation, and tenants can recover excess rent plus attorney's fees. Seattle adds its own enforcement: a lapsed RRIO registration runs $150 per day for the first 10 days, then $500 per day. Most violations aren't intentional. They come from an ordinary landlord not knowing a deadline had passed.
Figures from RCW 59.18.700 and Seattle's published RRIO penalty schedule; see individual tool pages for the specific statute behind each deadline.
