I am regularly asked by landlords where to turn for answers. Whether you are a landlord by choice or necessity I highly recommend that you join the Rental Housing Association of Puget Sound. They are a great resource for those of us that own rental property. Below are links to the RHA and many other important resources and informational (pdf) pamphlets to help you.
Here are some important resources for new and experienced landlords:
Landlord – Tenant Law (pdf) A summary of Seattle and Washington State landlord/tenant laws
Renters, Landlords, and Mold ~ Washington State Dept of Health
Got Mold? (pdf) Frequently asked questions
Smoke Alarms in Rentals (pdf) ~ Seattle Fire Dept.
