Residential Solar

What it 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). Split out of Residential MEP + Residential Alteration on classifier reclassification; segments are overlap-free, so a permit reclassified here is decremented from its prior segment at the source metro on the same regen.

How a permit lands in Residential Solar.

Every silver permit flows through a two-stage classifier. The deterministic stage maps the structured signals — work_class, the normalized permit type, and the building sub-type — into the segment vocabulary where the mapping is unambiguous. The machine-learning stage handles the cases that aren't direct lookups: multi-vocab permit-type strings, ambiguous occupancy spans, and jurisdictions that bundle categories. The segment is the classifier's output, the same axis across every metro — so solar_residential means the same thing in NYC as in LA even though the upstream jurisdictions emit completely different raw permit-type strings.

When the signal genuinely isn't there, we say so. A row with no assignable segment degrades honestly — to its work-nature, then to its raw source type, and only to “Unclassified” when truly nothing is known. We never guess a segment to fill a gap; an honest Unclassified is the floor, and field-level data-quality flags surface when the classifier had low confidence. That restraint is the point — the classification is only worth selling on if the “don't know” is honest.
