Building permits are public records — and each one represents a homeowner or developer ready to spend thousands. PermitSiren monitors official registers 24/7 and pings you the second a job matches your craft and territory.
No complex software to manage. No cold-call lists to scrub. You specify your craft once — instant leads ping your phone the moment property owners file.
Roofing in Cook County? EV charging in Miami? Dormers in Amsterdam? Choose your craft and coverage zones with zero friction.
Our edge workers ingest city, county, and national public records every few minutes — the exact official source records building inspectors use.
Get structured lead digests with exact address, job scope, valuation, contractor license details, and one-click municipal source verification.
Automated severe weather ingestion: hail ≥ ¾″ or 60 mph gust events automatically trigger immediate high-damage zone permit watches.
Contractors using fresh public filings get to homeowners before competitors even know the job exists. Test the math for your trade below.
At $14/month for PermitSiren Solo, closing just one single job covers your subscription for 89 years.

Directly from official government registers: municipal building open-data portals in the US (e.g. City of Chicago DOB, Austin Build+Connect, Seattle SDCI), KOOP/officielebekendmakingen in the Netherlands, MercatorNet in Flanders, and Nova in Brussels. We never scrape private marketplaces or resell cold third-party lists.
Yes. Building permits are statutory public records specifically intended for community and professional transparency. As an independent business, how you conduct outreach (direct mail, phone, in-person consultation) must comply with your local advertising regulations (e.g. TCPA/CAN-SPAM in the US, GDPR in the EU).
Our edge monitors continuously poll jurisdiction registers. Most alerts are dispatched within 2 to 5 minutes of official publication. You can inspect live per-source latency anytime on our System Status Page.
Subscribers who join during our open beta lock in the $14/month rate permanently. When public launch pricing rises to $19/month or higher, your subscription rate will never increase for the lifetime of your active account.
