Find just-permitted residential solar projects in your territory.

Frequently asked about residential solar permits.

What solar permits does PermitCore cover?

Residential Solar covers solar PV-system installs on residential-occupancy buildings — single-family rooftop PV, residential battery-storage pairings, and multifamily R-2 PV installs (the installer-class definitional axis: residential-PV-licensed crews work both single-family and small-multifamily). It is split out of Residential MEP and Residential Alteration on classifier reclassification; segments are overlap-free, so a permit reclassified into Residential Solar is decremented from its prior segment at the source metro on the same regen.

Can PermitCore tell me which solar panel or inverter brand was installed?

Not for solar — and we want to be precise about why, because we do ship brand detection elsewhere. Where a manufacturer is named in the permit text we detect and surface it today for HVAC and roofing equipment (see the /brands directory, ≥99% precision on the detected subset). Solar panel, inverter, racking, and battery makers are rarely written into the permit record, so we do not surface them as a brand rail for this vertical. What every solar permit does carry — address, scope, contractor, status, geocode, provenance, DQ flags, segment, and (for NYC) PLUTO geometry — is queryable per row. Use the metro + contractor signal to find just-permitted residential solar projects in your territory.

How much residential solar volume is in the index today?

Residential Solar carries 93K classified permits across 12 US metros with positive solar volume — an early-coverage segment concentrated in solar-mature metros. Every covered metro is one click away in the segment × metro index below, so installers and financiers can work solar filings city by city. Each metro landing page also surfaces its own current count.

Which metros have the deepest residential solar coverage today?

New York City leads residential solar (20K permits in metro). Coverage is early and concentrated — each count in the segment × metro index below is that metro's own classified volume, never the cross-metro total — so teams can size each market before they work it. Metros with no solar volume are simply absent rather than padded.

How fresh is the data?

Two signals, displayed side-by-side on every metro page. Source-data freshness — a “Latest permit” date with a days-since count — is the issued date of the most recent solar permit we hold for that metro; it tells you whether new PV filings are landing. Index rebuilt — a separate “index rebuilt” date — is when our pipeline last recomputed the artifacts that back the page. We display both because a quiet metro (no recent issued permits) does not mean a stale index. Older history is queryable via the API once you sign up.

Can I integrate this into my CRM?

Yes. Every permit returns as JSON via /v1/permits — address, scope, contractor, status, geocode, provenance, DQ flags, segment, and (for NYC) PLUTO geometry are all queryable per row. Pro tier ($89/mo) includes 100K API calls/month and unlimited exports. Self-serve checkout; no sales call required.
