Modifying requirements and allowed uses for certain funding related to providing and maintaining affordable housing and related services.

HB 2359 modifies Washington state law to change how a 0.1% sales tax revenue can be used for affordable housing and related services. It requires at least 60% of the funds to be spent on building or maintaining housing for low-income residents (at or below 60% of county median income), including veterans, the homeless, and people with disabilities, or on behavioral health facilities. The bill also mandates that 15% of new housing units must be reserved for people living near the facility, and allows local governments to use bonds and interlocal agreements to finance these projects. This law affects counties and cities that impose the tax, directing funds toward specific housing and services while ensuring community-focused allocation.
