Owning a home in San Francisco.

SF homeowners face complex city regulations that overlap with state law, including aggressive rent control on most pre-1979 buildings, just-cause eviction protections, and TIC/condo conversion rules. The Office of the Assessor-Recorder administers Prop 13 base-year values; supplemental assessments and Prop 19 transfers apply. Transfer taxes on high-value sales are among the highest in California.
