Why permits

Better leads than any ad platform

Traditional solar leads cost $50-200+ each. Permit data gives you homeowners who've already committed money to their property — the highest-intent prospects in the market.

10x

Higher intent than ad leads

A homeowner who just spent $15K on a new roof is in a construction mindset. They have a brand-new surface ideal for solar panels.

Per lead with free tier

1,000 free API requests per day. Each request returns up to 100 permits. That's up to 100,000 potential leads per day — for free.

24hr

Data freshness

Daily updates from city portals. Reach homeowners days after they file a permit — before your competitors even know the project exists.

Use cases

What solar companies build with permit data

Roofing → Solar leads

Homeowners with recent roofing permits have new surfaces ideal for panels. They've already invested in their property and are open to improvements.

Solar → Battery upsell

Find homeowners who installed solar 1-3 years ago. They're ideal candidates for battery storage add-ons as prices drop.

EV charger → Solar cross-sell

EV charger permit holders are environmentally conscious and have higher electricity bills — perfect solar candidates.
