Integration Notes

  • LA County uses a dedicated EPIC-LA portal. The API auto-detects this jurisdiction from the permit number format.
  • Permit data is cached for 4 hours. The data_freshness object in every response shows when the data was last fetched from the portal.
  • Pro and Enterprise plans can use force_refresh=true to bypass the cache and fetch live data.

The SignedOff API provides programmatic access to LA County building permit status via the EPIC-LA portal. Developers can query permit status, inspection results, and processing milestones as structured JSON without manual portal lookups.

LA County permit API questions

How do I check LA County permit status by API?

Send the permit number to the SignedOff status endpoint. The response returns structured status, inspections, milestones, and data-freshness details sourced from EPIC-LA.

What permit number format does LA County use?

A representative LA County permit number is BLD2024-00123. Permit formats can vary by record type and issue year, so applications should preserve letters, digits, and separators exactly as issued.

How fresh is LA County permit data?

SignedOff caches permit responses for up to four hours and reports the last refresh time in every response. Pro and Enterprise requests can use force_refresh=true when an immediate portal check is needed.

Does the LA County Permit API require a jurisdiction parameter?

No. SignedOff normally detects LA County from its permit number format and routes the request to EPIC-LA automatically.
