New Building Permit Monitor - Deduped Daily Contractor Leads (US)

Get newly issued building permits in major US cities as a clean, deduplicated feed — roofing, solar, HVAC, plumbing, electrical, pool, demolition and more. Run it on a schedule and receive only the permits that are new since your last run, never the whole pile again.

Built on official city open-data portals (NYC, Chicago, San Francisco, Austin). No scraping, no fragile page automation, and no owner personal data.

Who uses this

• Material suppliers, subcontractors, and service businesses: a new permit is a project about to start and a buyer about to spend. Reach out first.
• Solar / roofing / HVAC sales teams: filter to your exact trade and city and get a daily list of fresh jobs.
• Proptech and market analysts: track construction activity by city, trade and value.

Why "deduped monitor" matters

Most permit datasets dump the entire history every time. This actor remembers where it got to and emits only new permits on each run — so a daily schedule gives you a clean daily lead list, ready for your CRM or a webhook, with no duplicates to filter out.

The first run sets a baseline and emits nothing (there's no "previous" to compare to yet). New permits flow from the second run onward. Schedule it daily.

What this actor never collects

Permit records often contain the owner's name, home address, and the permittee's personal phone number. This actor emits the permit, the work, the value, the site address, and the contractor's BUSINESS identity only:

• No owner personal names
• No owner home addresses (separate from the job site)
• No personal phone numbers
• Contractor fields are business name and license number only, and only where the city publishes them as business data (currently New York City)

Notes

• Cities report on their own schedules; a permit may appear a day or two after issuance. The monitor handles late-arriving records by re-checking the boundary day each run.
• Trades are classified from each city's permit-type and work-description text; use the normalizedTrade filter for consistent cross-city trades.
• Found a problem or need a city or field added? Open an issue — replies are fast.
