NYC HPD enforces the Housing Maintenance Code through complaint-driven inspections. Tenants file complaints via 311, triggering HPD inspector visits within 7-30 days. Inspectors issue Class A (non-hazardous), B (hazardous), or C (immediately hazardous) violations with correction deadlines of 90, 30, or 24 hours respectively.
NYC's Department of Housing Preservation and Development (HPD) enforces the Housing Maintenance Code (Admin Code Title 27, Chapter 2) through a complaint-driven inspection system. Tenant complaints account for approximately 86% of HPD violation triggers. The process begins when a tenant calls 311 or files a complaint on the NYC 311 portal. HPD schedules an inspection, typically within 7 to 30 days depending on severity. Housing inspectors visit the property and issue violations for confirmed conditions. Violations are classified into three hazard classes: Class A (non-hazardous) with 90-day correction deadline, Class B (hazardous) with 30-day correction deadline, and Class C (immediately hazardous) requiring correction within 24 hours. Class C conditions include no heat/hot water, lead paint hazards, rodent infestation, and mold. HPD also conducts proactive enforcement in buildings enrolled in the Alternative Enforcement Program (AEP) and the Underlying Conditions Program targeting the worst buildings. Landlords who fail to correct violations face escalating penalties and HPD may perform emergency repairs, billing the owner.
Class A: 90-day correction. Class B: 30-day correction. Class C: 24-hour correction. False certification of correction: $50-$500 per violation. Emergency repair charges billed to owner.
