Three steps from zero to live permit data in your app.

03

Get Permit Data

Real-time status, dates, and inspection history. JSON, always.

SignedOff provides a REST API for querying real-time building permit status from municipal portals across the United States. The API returns structured JSON including permit status, inspection results, and processing milestones — data that would otherwise require manual lookups on individual city portals. Coverage spans Accela Citizen Access, LADBS, EPIC-LA, and EnerGov platforms, with new jurisdictions added on a rolling basis. Common integrations include solar installation pipelines, construction project management tools, and property due diligence platforms.
