Integration Notes

  • City of Ontario uses the Accela Citizen Access portal. Multiple cities share this platform, so include the jurisdiction=aca:ont parameter to avoid HTTP 300 disambiguation responses.
  • 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 Ontario building permit status via the Accela portal. Developers can query permit status, inspection results, and processing milestones as structured JSON without manual portal lookups. Because City of Ontario shares the Accela Citizen Access platform with other jurisdictions, API requests should include the jurisdiction parameter for direct routing.
