The Alternative Enforcement Program (AEP) is an enforcement program which identifies the 200 most distressed multiple dwellings citywide each year. Owners of multiple dwellings can avoid participation in AEP by properly maintaining their building, submitting a current and valid property registration to the Department of Housing Preservation and Development (HPD), and correcting and certifying all HPD violations. The City will let registered owners, managing agents, and tenants know that their building was chosen to be in the program.
