Questions

Is this data legal to use?
Yes. Building permits are public records that cities publish themselves. We collect, clean and organize them. Contacting contractors and owners about your services is standard B2B outreach.
Why not pull it myself from open data?
You can. Mechanical permits are mixed in with every other permit type, and the equipment and contractor are buried in the description. We pull out the commercial mechanical jobs every week and add the contacts.
How fresh are the permits?
New permits appear in the dashboard within a week of the city issuing them. On Pro, saved filters email you when a new permit matches.
What if a record is wrong?
Click "Report a problem" on the record and we'll fix it. If the data isn't useful, the 30-day money-back guarantee covers you.
Will I be charged after the trial?
Only if you keep it. We email a reminder the day before your trial ends, and you can cancel in one click.
Can I cancel any time?
Yes. No contracts. Cancel from your billing page and you won't be charged again.
Is my city covered?
We cover Chicago, Boston and Denver today. Tell us yours and we'll prioritize it.
