ADU & Addition Lead Generation from Building Permits
ADU & Addition permit leads, adu and addition advertising targets and follow-on work, from the public permits ADU builders and addition contractors pull in your ZIPs.
Quick answer. Permit-based lead generation for ADU builders and addition contractors starts from jobs that are already happening: public building permits. Curbside Signal has 2,823 residential adu and addition permits in the 8 weeks from Aug 31, 2026 to Oct 25, 2026 across the 8 metros where the adu and addition feed is on sale, and 17 adu and addition city pages. Plans start at $20/mo.
ADU & Addition permit leads
Each record is a real permit from a city or county: issue date, permit type, address and ZIP, scope, declared value where published and the contractor of record where published. We map each permit to the adu and addition trade and filter it to your ZIPs.
- Mail the neighbors of each ADU: lot sizes and rules are the same on the street.
- Subs: find the ADU builders pulling the most permits in your ZIPs.
- Watch declared values to see where larger projects cluster.
ADU & Addition advertising with permit data
- Spend where the work is: aim local ads and mailers at the ZIP codes with the most adu and addition permits.
- Market to the neighbors of active jobs: same-age houses on the same street often need the same work.
- Follow-on demand. ADUs and additions drive HVAC, electrical, plumbing, solar and landscaping work.
The honest limit. A permit usually means the job is already sold. We say that up front. The value is what happens around it:
- Neighbor marketing around active jobs: same-age houses on the same street.
- Cross-trade follow-on demand: new roof → solar, gutters, insulation; remodel → HVAC, electrical, landscaping, pool; new build → pest, security, landscaping.
- Contractor activity: which contractors pull permits where (where the jurisdiction publishes it), and who to recruit as subs.
- Early-stage projects for commercial trades and GC subs.

Questions
How does permit-based lead generation for ADU builders and addition contractors work?
Cities and counties publish building permits. We pull them, keep residential adu and addition permits, and send you the ones in your ZIPs every Monday as a CSV with the address, scope and value. You use them for neighbor marketing, follow-on offers and ad targeting.
How much do adu and addition permit leads cost?
Starter is $20/mo for one trade and up to 5 ZIPs. Whole City is $140/mo for a whole metro and up to 5 trades. Guarantee on every package: If a month comes in under half the 8-week average permit count for your ZIPs and trades, you get 50% off next month. If a weekly file is ever late or missing, you get 50% off next month.
Can I use permit data for adu and addition advertising?
Yes. Point mailers, door-hangers and local ads at the ZIP codes where adu and addition permits are being pulled, and at the streets around active jobs. The permit file tells you where; it does not include homeowner phone numbers or emails.
Does a permit mean the job is still open?
Usually not: a permit typically means the job is sold. The value is neighbor marketing around active jobs, cross-trade follow-on work, and contractor activity where the jurisdiction publishes it.
