Concerning seismic hazard risk reduction.

HB 1810 requires Washington state to study financial incentives for seismic retrofits of older brick buildings (unreinforced masonry structures) and create a statewide inventory of such buildings. It directly affects building owners of vulnerable historic properties, local governments using the inventory for planning, and taxpayers through potential tax changes. Key provisions include a 2026 study on tax modifications (like special valuation or exemptions) to reduce retrofit costs, and a 2030 deadline to catalog all such buildings using existing data and on-site verification. The bill aims to make retrofits more affordable to protect public safety and preserve affordable housing, without mandating retrofits. It expires in 2026 for the study and 2030 for the inventory work.
