Certificates of Occupancy

This information does not cover every possible kind of situation under which Building Permits and Certificates of Occupancy may be required. In addition, some kinds of work require special permits from the New York State Department of Environmental Conservation, as well as other local, state, and federal agencies.

The Certificate of Occupancy is the Town’s assurance to a prospective buyer or owner that a building or home is legally occupied and that it conforms to zoning, minimum repair and maintenance standards as of the date the Certificate of Occupancy is issued.

A Certificate of Occupancy is required when there is:

  1. An initial occupation of a new building.
  2. An alteration of an existing building.
  3. A change in use or occupancy.
  4. When a Building Permit has been issued.

The Certificate of Occupancy inspection is a thorough inspection of the interior and exterior of the premises as applicable.

The Certificate of Occupancy permits and authorizes the use and occupancy of the land or premises as described in the permit application.

No Certificate shall be issued except upon an inspection which reveals no uncorrected deficiency or material violation of the NYS Uniform Code , Energy Code and/or Town Codes.

No building erected subject to the NYS Uniform Code, Energy Code shall be used or occupied until a Certificate of Occupancy has been issued. Similarly no building that has been altered, extended or enlarged shall be occupied or used for more than 30 days after completion unless a Certificate of Occupancy has been issued.

The requirements for a Certificate of Occupancy are compliance with all applicable codes, rules, and regulations some of which are:

  • NYS Uniform Fire Prevention & Building Code
  • Town of Clarkstown Zoning Ordinance
  • All applicable Town Codes & Section 109-6
  • NYS Energy Code & Multiple Residence Law Town Of Clarkstown Fire Code

The requirements for a Certificate of Occupancy can be found in the Property Maintenance Code, Housing Code Building Code, and Zoning Ordinance, as well as in the New York State Multiple Residence Law, but are written in complex legal terms and may be somewhat confusing to most people.

If the building meets zoning approval and is found to be in compliance with applicable codes, ordinances and regulations, the Building Department will issue a Certificate of Occupancy.

For Certificates of Occupancy to be issued on permits that have expired or for existing building, built before the adoption of the zoning and building codes an additional fee is required.
