Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
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.
Inspection lane
Licensed professionals and other authorized applicants request construction, electrical, plumbing, elevator, boiler, and related inspections through DOB NOW: Inspections. Bronx construction-development inspections use 718-960-4709; enforcement inspections use 718-960-4730; certificate-of-occupancy inquiries use 718-960-4740.
Minor-work playbook
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.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Licensed professionals and other authorized applicants request construction, electrical, plumbing, elevator, boiler, and related inspections through DOB NOW: Inspections. Bronx construction-development inspections use 718-960-4709; enforcement inspections use 718-960-4730; certificate-of-occupancy inquiries use 718-960-4740.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Bronx DOB Customer Service: 718-960-4710; Construction Development: 718-960-4709; Construction Enforcement: 718-960-4730; DOB main: 212-566-5000.
N/A; review time varies by filing type, professional certification, objections, and whether the application is filed through DOB NOW or BIS.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
