Here are the key instances when filing is necessary:
1. Structural Changes: Any modifications that affect the building’s structure, like adding or removing load-bearing walls, floors, or ceilings, must be filed. This also includes changes that impact beams or other structural elements.
2. Change of Use or Occupancy: If a space's use changes (e.g., converting office space to a restaurant), an amended or new Certificate of Occupancy is required. Additionally, modifications that alter the occupant load of a space trigger the need for DOB approval.
3. Plumbing, Gas, and Electrical Work: Installing or altering plumbing systems, including gas lines, water distribution, or vent pipes, requires a permit. Changes to electrical systems must also be filed, especially if they involve major upgrades or relocation of electrical services.
4. Fire Safety Systems: Any work that involves the installation, removal, or adjustment of fire alarms, sprinkler systems, or other fire suppression systems must be filed with the DOB. Modifications to paths of egress, such as exits or emergency escape routes, also require approval.
5. Emergency and Minor Repairs: Emergency work can begin without a permit if it is necessary to resolve immediate hazards, but a permit application must be submitted within two business days. Minor repairs, like replacing plumbing fixtures or minor adjustments to non-structural elements, may not require permits. However, even minor changes can require filing if they impact safety systems or structural integrity.
