Browse temporary construction support permits in New York City →What it covers
Temporary construction support permits cover scaffolding, hoists, sidewalk sheds, temporary fencing, construction trailers, and other interim structures filed to support an active construction project. In dense urban environments (NYC especially) this segment can be the second-largest by volume because every major project files multiple temp-support permits as the work progresses.
How a permit lands in Temporary Construction Support.
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 temporary_construction_support 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.
