Energy & climate
Electrification happens at the permit desk.
Utility interconnection queues run months behind. Survey data is self-reported. But almost every rooftop solar array, heat pump swap, battery wall, and Level 2 charger starts as a permit filed with a local jurisdiction. 74M+ permits across 42 states, so you can measure the energy transition where it actually gets recorded first.
Demand signals you can count
Solar permit volume by county is a direct read on residential adoption. HVAC replacement permits track the heat pump transition, one mechanical filing at a time. EV-charger and panel-upgrade permits show which neighborhoods are wiring up for load growth. None of it is modeled. It's filed paperwork with an address and a date on it.
- ✓Count solar, HVAC, electrical, and mechanical permits by county and month
- ✓Trend adoption curves over time from filing dates, not press releases
- ✓Rank counties and metros by electrification permit velocity
- ✓Find the installers doing the volume in any market
- ✓Backtest incentive programs against actual permit response
- ✓Pull it all over one API instead of chasing jurisdiction portals one at a time
Who uses this
Solar and storage companies sizing expansion markets by real installation activity. Climate fintechs underwriting installers on permit throughput instead of self-reported revenue. Researchers and policy teams who need adoption data at county resolution, with a published methodology behind every count. Utilities watching distributed generation show up on their grid one rooftop at a time. Different jobs, same underlying records.
The honest tier note
Florida is Tier 1: permits there are matched to DBPR contractor licenses, so installer research includes verified contact and license status. The other 41 states are permit records via the API: address, work type, valuation, dates, contractor as filed. Every state carries a published coverage grade and a public permit count.
