Certification of No Harassment

Certification of No Harassment 

Under local law, if a residential building meets any of the following criteria the property owner must apply for and receive a Certification of No Harassment (CONH) before applying to the Department of Buildings (DOB) for a permit to change the use or occupancy of a building or to demolish a building or any part thereof. These requirements apply if the building is:

  • A single room occupancy multiple dwelling (SRO). A single room occupancy multiple dwelling is:
    • A “class A multiple dwelling” used in whole or part as a “rooming house” or “furnished room house,” or for “single room occupancy” pursuant to section 248 of the New York state multiple dwelling law;
    • A “class A multiple dwelling” containing “rooming units”; or
    • A “class B multiple dwelling.”
  • A multiple dwelling or interim multiple dwelling located in one of the following geographic areas (as specified in the New York City Zoning Resolution):
    • The Special Clinton District - § 96-110; or
    • The Special Hudson Yards District – § 93-90; or
    • The Special Garment Center District – § 93-90; or
    • The Greenpoint-Williamsburg anti-harassment area – § 23-013; or
    • The Special West Chelsea District – § 98-70 and § 93-90.

The CONH process is intended to ensure that the owner or its predecessors did not further proposed alteration or demolition projects by harassing lawful occupants into leaving or otherwise depriving lawful occupants of their rights during the statutory review period. The Housing Litigation Division (HLD) investigates to determine whether harassment occurred during the applicable inquiry period. If HPD determines that there is reasonable cause to believe that harassment occurred, HLD initiates HPD's case at the Office of Administrative Trials and Hearings (OATH), which makes findings of fact and recommendations as to whether harassment occurred. Based on OATH’s recommendations, the Commissioner of HPD or the Commissioner's designee then determines whether to issue the CONH. A denial of the CONH prevents the owner from obtaining any permits to materially alter or demolish the building for a period of years under the applicable law.

To apply for a CONH, a property owner must complete the application and pay the required fee as noted on the application (Note: this fee will increase to $160 per existing unit for applications submitted after July 1, 2018).

Applications may be submitted to HPD online or by our paper application process.

CONH Pilot Program

Local Law 1 2018 (effective September 28, 2018) establishes a three-year pilot program which requires owners of certain buildings to obtain a Certification of No Harassment (CONH) prior to acquiring permits from the Department of Buildings (DOB) for work involving demolition or change in use/occupancy. As set forth in the law, buildings with high levels of physical distress or ownership changes in certain targeted areas of the City will be placed on a building list. Also included on the list will be buildings that are the subject of a full vacate order, have been active participants in the alternative enforcement program for more than four months since February 1, 2016 and buildings in which there has been a finding of harassment within the last five years by a court or by New York State Homes and Community Renewal.

Pilot Program Building List

Property owners of buildings on the list will be required to receive a CONH from the Department of Housing Preservation and Development (HPD) before the Department of Buildings (DOB) can approval new construction applications for an initial or reinstated permit to perform certain covered categories of work.

Covered categories of construction work:

  • Full and partial demolition of the building;
  • Change of use or occupancy for:
    • all or part of a dwelling unit;
    • any residential portion of the building.
  • Any alteration which would:
    • add or remove kitchens or bathrooms;
    • increase or decrease the number of dwelling units;
    • change the layout, configuration, or location of any portion of a dwelling unit;
  • Application for a new or amended Certificate of Occupancy;
  • Removal of a central heating system and replacement with an individually metered heating system.

Applications may be submitted to HPD online or by our paper application process.

  • Online: You may submit a CONH Application via the HPD Enforcement Desk. You must establish a new user account for this application (you cannot use your existing PROS or eCertification accounts). You must confirm your user account registration by responding to the HPD Enforcement Desk confirmation email.

  • Paper Application Process: Please see the CONH Pilot Program Application for complete instructions about how to apply and information regarding the submission of additional documents. Note: If you are using Google Chrome and the application does not open, please try a different browser.

Applications for a CONH Pilot Program Exemption may only be submitted to HPD by our paper application process.

HPD will investigate CONH Pilot Program applications to determine whether there has been harassment of tenants at such building within the five-year period preceding the application. Once a building owner subject to the program applies for a CONH, building tenants, community groups, the community board, and elected officials will be notified. HPD will collect comments from current and former tenants and conduct an investigation to determine whether there is evidence of harassment within the previous five years. If HPD determines evidence of harassment exists, a hearing will be held at the Office of Administrative Trials and Hearings (OATH).

After the hearing, the OATH judge will issue a report and recommendation as to whether harassment occurred based on the evidence heard and, based on that recommendation, the HPD Commissioner will grant or deny the CONH. If the owner is denied a CONH, the owner will be precluded from receiving building permits for the covered categories of work for five years, or, in the alternative, the owner may construct a certain percentage of low income housing units to address the harassment finding.
