HPD Online Glossary
ERP Emergency repair program If an HPD inspector verifies an emergency condition in a building, the last validly registered owner and managing agent of the property will be notified of said emergency condition by letter and/or by phone and instructed to repair the condition. If the owner fails to make the necessary repairs in a timely manner, HPD's Emergency Repair Program (ERP) may repair the condition. If HPD's ERP repairs the emergency condition, HPD, through the Department of Finance, will bill the owner for the cost of repairs. If the owner fails to pay the bill within 60 days, a lien is placed on the property.

Violation Desc. Violation Description HPDonline provides access to violations of record of the New York City Housing Maintenance Code and the New York State Multiple Dwelling Law in privately owned residential multi-family buildings in the City of New York. These laws state that it is the responsibility of owners to provide essential services, to maintain their properties in habitable conditions, and to correct and repair housing code violations. The accuracy of the HPDonline data is not guaranteed and should be used for informational purposes only. The violation report will reflect information on three classes of housing code violations:
  • A (non-hazardous, such as minor leaks, chipping or peeling paint when no children under the age of six live in the home, or lack of signs designating floor numbers. An owner has 90 days to correct an A violation and two weeks to certify repair to remove the violation).
  • B (hazardous, such as requiring public doors to be self-closing, adequate lighting in public areas, lack of posted Certificate of Occupancy, or removal of vermin. An owner has 30 days to correct a B violation and two weeks to certify the correction to remove the violation.)
  • C (immediately hazardous, such as inadequate fire exits, rodents, lead-based paint, lack of heat, hot water, electricity, or gas. An owner has 24 hours to correct a C violation and five days to certify the correction to remove the violation. If the owner fails to comply with emergency C violations such as lack of heat or hot water, HPD initiates corrective action through its Emergency Repair Program.)
Once a landlord corrects a violation he or she may remove it from the record by certifying that the violation was corrected within the required time period specified on the Notice of Violation. Certification instructions can be found on the back of the Notice of Violation. After the specified time period has passed, landlords may ask for a reinspection by filing a Dismissal Request form with their Borough Code Enforcement Office for a $300 fee. To report a maintenance issue, tenants may call the City's Citizen Service Center at 311, 24 hours a day, 7 days a week (311 can be accessed outside of New York City by dialing (212) NEW YORK).
