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 allows renters and mobile home occupants in Washington to install portable cooling devices (like window units or floor models) without landlord approval, with key exceptions for safety, building codes, or existing heat pumps. Landlords cannot charge fees for installation or restrict devices, but may require proper drainage and 48-hour notice for inspections. They must disclose insurance restrictions on window units in leases and inform tenants of their rights. The law does not override existing disability accommodation requirements or landlord responsibilities for electrical issues caused by tenant devices.
