Integration Notes

  • City of Costa Mesa uses a dedicated EnerGov source, and SignedOff normally detects it 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 City of Costa Mesa building permit data from its official public source. Developers receive structured status and data-freshness fields, plus inspections and workflow detail when the official source publishes them without repeating manual lookups. Available fields remain source-specific, and the official jurisdiction record is authoritative.
