How It Works

Search once. Follow a place.
Stay ahead of construction.

No complex software to manage. Search official records, save an address or area, and let PermitSiren collect newly published filings for your weekly digest.

  1. 1. Search by place & scope

    Look up a street, postcode, municipality or metro. Filter by roofing, solar, renovation, demolition and other public project types.

  2. 2. Continuous register polling

    Our edge workers ingest city, county, and national public records every few minutes — the exact official source records building inspectors use.

  3. 3. Weekly saved-area digests

    Follow the places you care about. Each week, receive only the new filings that match your saved areas, with one-click municipal source verification.

  4. 4. Storm Radar Mode Beta

    Automated severe weather ingestion: hail ≥ ¾″ or 60 mph gust events automatically trigger immediate high-damage zone permit watches.

Public Permit Radar

Every filing becomes findable context.

Use PermitSiren as a transparent map of local construction activity: research a street, check nearby work, monitor a neighbourhood, or follow a municipality without logging into fragmented portals.

Why Switch

The old legacy way vs PermitSiren.

Permit data has historically been locked behind enterprise software requiring $5,000 annual commitments. We deliver high-velocity public data directly to trade professionals.

Old-school Enterprise Tools

  • Weekly or bi-weekly PDF batches — leads are cold on arrival
  • $200 – $800/mo forced annual contract lock-in
  • Clunky web dashboards you must manually log into and search
  • Built for national corporations; single crews ignored

PermitSiren Advantage

  • Continuous edge polling — alerts ping you within minutes
  • Transparent open-beta pricing with no annual contract lock-in
  • Direct push to phone, email, SMS, or CRM webhooks
  • Purpose-built for independent trades and one-van crews
Transparent Pricing

Simple, honest pricing during open beta.

Open-beta members keep their current rate while their paid account remains continuously active. Public launch pricing will be announced before the beta ends. No hidden onboarding fees, no multi-year lock-in.

Frequently Asked Questions

Answers to common questions.

Where does the permit data originate from?

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.

How may I use public permit records?

Building permits are official public records, but reuse rules and privacy obligations differ by jurisdiction. PermitSiren applies data minimization when processing European register data; you remain responsible for any downstream use, including TCPA/CAN-SPAM in the US and GDPR rules in Europe. Review our Privacy Policy and obtain professional advice where needed.

How quickly are alerts dispatched?

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.

What does the Open Beta Rate guarantee?

The beta rate is a bounded early-access offer, not an unconditional lifetime price. Members who join during open beta keep $14/month while their paid account remains continuously active. If a subscription lapses or is cancelled, reactivation uses the then-current published rate.
