These filings are grouped by a normalized work-type, not a keyword scrape. We read each permit’s work-type, scope, and occupancy fields to place it under Residential Addition — so a filing that looks like a generic alteration lands in the right bucket. When the fields don’t support a confident call we leave it unclassified rather than force a wrong type.
