Bronx County permit authority
The first compliance decision is jurisdictional: identify the office with statutory authority over your parcel, then use its filing and inspection sequence to keep the project moving.
Jurisdictional status
Municipal Fallback
This profile identifies a handoff outside the county’s ordinary structural permitting lane.
Required jurisdiction check
Confirm the controlling local or state authority before filing.
The record is marked Municipal Fallback. That means the county profile should be treated as a routing brief: incorporated municipalities, a state building department, or a state fire marshal may control plan review, permits, and inspections. Contact the named agency below and verify the parcel’s jurisdiction before paying a fee or scheduling field work.

Which codes and exemptions should I review?
The 2022 New York City Construction Codes and NYC Administrative Code govern current construction and existing-building work. The NYC Existing Building Code was enacted in 2026 but its effective date is July 17, 2027; the 2025 NYC Energy Conservation Code/ASHRAE provisions also apply where specified. NYC states that the majority of construction requires a Department of Buildings permit and directs applicants to NYC Building Code §27-126 for permit-required work. Specific exemptions depend on the work type; confirm with DOB before treating a repair or alteration as exempt.
