From public building permit records, most recent October 2, 2026. Updated daily. Counts include every permit type a jurisdiction files — trade permits (electrical, plumbing, mechanical) as well as building permits — so one project can appear more than once. Values are what the applicant declared, where the jurisdiction records one. We keep improving how we collect each office's permits, so a count that steps up suddenly usually means more complete records, not more construction.
