California Construction Permit Index
What California is building — a 30-day permit snapshot.
An open snapshot of building activity across California's live metros, drawn from official public permit records. Solar leads the adjacent-buyer demand across Los Angeles, San Francisco and San Jose. Free to cite.
California coverage shows what each market's record publishes. San Jose's permit record names the owner and, on most permits, the contractor. San Diego's owner name and mailing address come from the county assessor. Sacramento County names the contractor on most permits. Los Angeles, Los Angeles County, San Francisco and Corona name neither. PermitVector does not sell owner phone numbers or emails in any state.
