NYC Building Permit Requirements

In NYC, a building permit is required before you begin:

Any structural alterations to walls, foundations, or load-bearing elements
Additions, extensions, or new construction
Changes to building use or occupancy classification
Plumbing work including new fixtures, relocations, or sewer connections
Electrical installations and panel upgrades
HVAC system installations, modifications, or replacements
Fire protection and life safety system installations
Demolition of any part of an existing structure
Facade repairs and exterior modifications
Sign installations and modifications
