Browse multifamily mep permits in Austin →What it covers
Multifamily MEP permits cover mechanical, electrical, and plumbing system work on apartment and condo buildings — boiler and riser replacements, electrical service upgrades, and unit-level plumbing reroutes filed against multifamily stock rather than single-family or commercial. Distinct from Multifamily Alteration, which covers the building and envelope work these systems sit inside; segments are overlap-free, so a permit classified here is not double-counted there. Currently concentrated in the metros whose source feeds separate multifamily MEP filings from general alteration filings — check the per-metro coverage before reading a low count as low activity.
How a permit lands in Multifamily MEP.
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 multifamily_mep 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.
