We publish counts by ZIP code and by contractor, not a list of permits by street address. The full record for one property, with every permit, its status and its inspections, is kept by the office that issued the permits; our source here is San Diego County Planning & Development Services building permits on homes in the unincorporated county (the County's open-data permit, contractor and status-history files). Ask that permit office for a property's permit history, or search its public records by address.
For a contractor you are about to hire, open their page from the lists above to see every permit they pulled across San Diego County. San Diego County permit statistics → · How the records work in San Diego County →
Source: San Diego County Planning & Development Services building permits on homes in the unincorporated county (the County's open-data permit, contractor and status-history files). The window is October 2023 through September 2026. Each permit is placed by its property's ZIP code (the address on the permit, or the parcel's when the permit has none).
Counted: permits on homes for the 19 kinds of work we track (solar, HVAC, electrical & service upgrade, battery storage, re-roof, plumbing, water heater, windows & doors, pool & spa, new home, remodel & repair, EV charger, combined electrical, plumbing & mechanical, ADU, garage, patio cover & accessory structure, addition, retaining wall, manufactured home installation, demolition) where the record names a contractor. Not counted: commercial work, trades we don't read, and permits with no contractor (owner-pulled work). So this is not the county's count of every permit in 91901.
A ZIP code does not follow city or county lines; these count only permits in unincorporated San Diego County. Counts are permits, not jobs: one job can need several permits.
