Housing Preservation & Development (HPD)
The housing regulator — maintenance-code violations, registration, heat and hot water, and lead.
What HPD regulates
HPD enforces the Housing Maintenance Code for residential buildings — the rules that keep apartments habitable. It handles annual property registration, heat and hot water complaints, repairs, and lead-paint duties, and it classifies violations by severity.
What owners get from HPD
- Class A (non-hazardous), Class B (hazardous), and Class C (immediately hazardous, e.g. no heat, lead, mold) violations.
- Heat/hot-water violations and Emergency Repair Program (ERP) charges when the City makes repairs.
- Failure-to-register consequences (can’t certify violations or sue for rent).
