Browse residential fire protection permits in Boston →What it covers
Residential fire protection permits cover life-safety systems filed against single-family and small residential stock — 13D residential sprinkler systems, hardwired alarm and detection work, and suppression on attached garages and accessory structures. Split out of Residential MEP and Residential Alteration on classifier reclassification. The smallest of the three fire segments by volume, because most jurisdictions do not require a separate permit for residential sprinkler work outside new construction. Published for 26 of the 36 jurisdictions where fire-protection filings are currently classified. At least 69 jurisdictions in the index publish fire-shaped permits, so a metro with no volume here almost always means we have not yet mapped its filing types — not that the work is not happening. Check the per-metro coverage before reading a low count as low activity.
How a permit lands in Residential Fire Protection.
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 residential_fire_protection 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.
