Allows users to check if a unit in a multifamily building in WA state is covered by a new rent stabilization law and calculates a score on sound insulation between units.
- Every King County multifamily building on one map: rent stabilization coverage, exemption expiry dates, noise score, and the raw county record.
- A scoring model estimates each building's noise insulation from its construction data, with the full breakdown shown on every building's card.
- Replaces hours of digging through assessor extracts, GIS parcels, and permit records with a single search.
