🏘️ 6 Things Every Buyer and Seller Should Know About ADUs in Washington Now
Washington State law now makes it easier to add a second living space to many properties, and it is changing how buyers and sellers think about value.
1️⃣ Most single family lots now qualify
Recent state law expanded where accessory dwelling units are allowed.
2️⃣ ADUs can mean rental income
Extra income potential is a real draw for buyers looking at long term flexibility.
3️⃣ They can also mean multigenerational living
A private space for parents, adult children, or grandparents, all on one property.
4️⃣ Sellers should document everything
Permits and proper documentation for an existing ADU protect your sale.
5️⃣ Financing can look different
Ask your lender how an ADU affects appraisal and loan options early.
6️⃣ Not every ADU is created equal
Permitted, code compliant units are valued very differently than unpermitted ones.
💡 Whether you are buying a home with one or selling a home that has one, an ADU is worth a real conversation, not just a line in the listing.
