Stop polling. After each nightly ingest, PermitStack pushes every new matching permit to your webhook within about a minute — or emails you a clean daily/weekly lead feed for your trade and metro. Built for solar, roofing, HVAC, and pool contractors, and the developers building tools for them.

Pick the one that fits how you work — or use both.
An HTTP POST to your endpoint as soon as a newly ingested permit matches your filters. Wire permits straight into your CRM, Slack, or app — no cron job, no polling.
A clean daily or weekly digest of brand-new permits matching your trade and metro, delivered to your inbox. No code, no API — just leads.
Most permit-data products either make you poll a slow dataset or sell you a static lead list through a sales call. PermitStack pushes fresh permits to you, self-serve.

For the people who buy permit data, a permit is a clock starting.
A filed permit means a homeowner just committed budget to a project a competitor is doing nearby. Reaching them the same week — not a month later — is the whole game. A monthly-refresh dataset misses the window entirely.
New construction and major remodels are your pipeline. Get a weekly feed of exactly your category in exactly your metros and work the list — no scraping, no spreadsheets, no per-area sales contract.
A roof, solar, or addition permit is a property-condition signal. Webhook it into your underwriting or book-of-business monitoring as soon as it reaches our data.
Don't build a polling loop against a slow dataset. Register a webhook, verify the signature, and ship. New permits show up in your product after each nightly ingest, without a polling loop.
Webhook deliveries run on a 60-second dispatch loop, so a matching permit is pushed within about a minute of landing in our database. How soon it lands depends on the source: most jurisdictions are ingested once a night, some publish permits days or weeks after filing, and a few sources are currently access-blocked (the coverage page shows each one's data-through date). So alerts are same-day-after-ingest, not the instant a permit is filed at city hall.
Webhooks push a signed JSON payload to your endpoint within about a minute of a matching permit being ingested (most sources are ingested once a night) — built for developers wiring permits into a CRM, Slack, or an app. The email lead feed is a scheduled digest (daily or weekly) of new permits matching a saved search — built for trade contractors who just want fresh leads in their inbox, no code required.
Saved-search email digests are available on every plan, including free (up to 3 saved searches). Webhooks are available on Developer ($79/mo) and above. See the pricing page for the full breakdown.
Webhooks filter on city, state, ZIP, category (solar, roofing, HVAC, pool, electrical…), description keyword and contractor name. Saved-search digests use the search API's filters. You only get notified about permits that actually match.
Yes. Every payload is signed with an HMAC-SHA256 signature in the X-PermitStack-Signature header so you can verify it came from us. Failed deliveries retry with backoff, and we record failures for debugging.
Traditional permit-lead vendors sell you a weekly PDF/CSV per metro through a sales call, often $90–$470/month for a single area. With PermitStack you self-serve any covered metro, get an API and webhooks (not just a static list), and pay one flat transparent price.
Get a PermitStack API key with email verification — no sales call, no credit card. 100 free requests per day.
