Housing

HB 1345 restricts detached accessory dwelling units (ADUs) - separate small homes on the same lot as a main house - outside urban growth areas in Washington counties. It requires counties to limit each parcel to one ADU, set size limits (max 1,296 sq ft), mandate water metering and sewage capacity documentation, and require ADUs to be within 150 feet of the main home. Counties must enforce penalties for unpermitted ADUs (including $1,000 fines, removal orders, and 3-year permit bans) and track ADU permits for land-use planning updates. The bill applies only to counties allowing such ADUs outside urban areas, not affecting existing urban or rural ADU rules.

This bill modifies Washington's covenant homeownership program, which provides down payment and closing cost assistance to eligible first-time homebuyers from historically marginalized communities. It raises the household income eligibility threshold for participants from 100% to 140% of the area median income. The bill also introduces a provision allowing for full loan forgiveness after five years for participants whose household income is at or below 80% of the area median income at the time of the loan. Additionally, it adjusts the membership of the program's oversight committee.
