Brooklyn Alterations May Need a No-Harassment Certificate

A Brooklyn owner planning major work should check the CONH question before pricing the job. Some residential buildings need a Certification of No Harassment before the owner applies to DOB for certain permits. The rule can apply before work that changes use or occupancy, demolishes part or all of a building, or makes covered alterations. Covered work can include adding or removing kitchens or bathrooms, changing unit layouts, or seeking a new or amended certificate of occupancy.

Tenants and local officials are notified after an application. Start with the building category, then the work type.

Keep the building address, HPD application, tenant or official notice, and any HPD response with the DOB project records. Confirm the CONH step before applying for a covered DOB permit.
