Promoting transit-oriented development.

SB 5604 creates a 20-year property tax exemption for new housing projects located within a designated "station area" (within 0.5 miles of a major transit stop) in Washington. To qualify, projects must include at least 20% of units affordable to low- or moderate-income households (defined as 50-80% of local median income) for 50 years, with long-term covenants ensuring affordability. Local governments must adopt regulations for station areas and oversee compliance, including recording deeds to maintain affordability. The bill aims to incentivize housing near transit by reducing development costs while mandating long-term affordability for residents.
