Real-time permit status for any building permit in 41+ jurisdictions. One API call.
Three steps from zero to live permit data in your app.
Sign up free. Get your key in seconds. No credit card required.
One API call with your permit number. We auto-detect the jurisdiction.
Real-time status, dates, and inspection history. JSON, always.
Query permits by criteria when you don't have a permit number — ZIP, lat/lon radius,
permit type, date range, or valuation. Searches run live against the source portals,
so results are what the jurisdiction has on file right now. Feed any hit into
/permits/{number}/status and track it.

What you can build
Direct answers to the monitoring, identity, lifecycle, and integration questions teams ask before they build.
Subscribe a signed webhook to permit_created to receive newly observed permit identities from the daily LADBS and EPIC-LA discovery monitor. This event requires a paid live key with the Permit Discovery add-on, starts after a no-event baseline, and reports when SignedOff first observes a permit — not the government’s legal filing time.
New-permit event details →
Save supported discovery filters with POST /api/v1/saved-searches; after the first successful baseline, a daily evaluation emits criteria_match for each first-seen match. Monitoring requires a paid live key and the Permit Discovery add-on, with 3 active queries on Developer, 10 on Pro, and 50 on Enterprise.
Saved-search monitoring details →
SignedOff normalizes a permit number plus jurisdiction into an immutable canonical UUID, so every customer refers to the same tenant-neutral permit resource. Resolution does not scrape the portal; ambiguous permit formats require an explicit jurisdiction or return ranked choices. Canonical ID details →
Yes. Dedicated endpoints return source-published conditions and holds, correction states, inspections, workflow activity, and lifecycle history from the latest successful portal representation. Detail varies by jurisdiction, and an unobserved field does not prove the agency has no matching record. Conditions, inspections, and history docs →
Yes. The official signedoff-api Python package and @signedoff/api TypeScript package are generated from the committed API contract and include typed endpoints, models, and API-key configuration.
SDK installation and examples →
Request a durable refresh with Prefer: respond-async, then subscribe the same API key’s webhook to operation_completed. SignedOff delivers the terminal result or typed error without requiring a watched permit; asynchronous refresh requires a paid live key and webhooks use the plan’s active-webhook limit.
Asynchronous refresh details →
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. A criteria-based discovery endpoint (/permits/search) additionally finds permits by ZIP, radius, permit type, date range, or valuation — currently covering the City of Los Angeles (LADBS) and unincorporated LA County (EPIC-LA) with live portal queries. 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.

Frequently asked
The API returns live status from LADBS (City of Los Angeles), Accela Citizen Access cities, EPIC-LA (LA County), and EnerGov jurisdictions, with new cities added regularly. Call GET /api/v1/jurisdictions for the current machine-readable list, or browse the coverage page.
Yes. The Free plan includes 200 requests per month with no credit card. Paid plans add higher limits and features: Developer is $49/mo for 5,000 requests, and Pro is $149/mo for 25,000 requests. Enterprise is custom.
Pass your API key in the X-API-Key header on every request. Sign up free to get a key in about a minute, then start with 200 requests per month.
Yes. The interactive playground runs every endpoint against a curated demo dataset with no key and no signup (30 calls per day per IP). Sign up free when you want live data and your own key.
Yes. SignedOff runs a remote Model Context Protocol server at /mcp, so Claude, Cursor, and other MCP-capable AI agents can look up live building-permit status as a tool. See the MCP setup page for connection details.
Each response serves recently cached data when it is still fresh and falls back to a live scrape of the source portal otherwise, so you always get the current status of record. Paid plans can force a live re-scrape with the force_refresh parameter.
Yes. The permit discovery endpoint (GET /api/v1/permits/search) finds permits by criteria: ZIP, lat/lon radius, permit type, date range, or valuation. v1 covers LADBS (City of Los Angeles) and EPIC-LA (LA County unincorporated) with live portal queries, and every free key includes 5 searches per month. See the permit search API page for details.
