Do You Need a DOB Permit in NYC? Repairs, Alterations and Emergencies
Which NYC work needs a Buildings Department permit, what counts as a minor alteration or ordinary repair, how emergency work is filed and who may do it.
By Seayora Editorial Team · Published · Facts checked · 3 min read
Short answer: Most construction in New York City needs Department of Buildings approval and a permit. Minor alterations and ordinary repairs, such as painting, plastering, new cabinets, replacing plumbing fixtures, resurfacing floors and non-structural roof repair, do not. Emergency work can start before a permit if a licensed contractor files an Emergency Work Notification within two business days of finishing, and residential home improvement work needs a separate license from the Department of Consumer and Worker Protection.
Key takeaways
- Painting, plastering, new cabinets, plumbing fixture replacement, floor resurfacing and non-structural roof repair do not need a DOB work permit.
- Electrical and plumbing work need licensed tradespeople, and most of it needs a permit even when it is small.
- Emergency work may start first, but a licensed contractor must file an Emergency Work Notification within two business days after completing it.
- A contractor doing residential home improvement work in NYC needs a Home Improvement Contractor license from DCWP.
Which work needs a DOB permit?
The Department of Buildings says most construction in New York City requires its approval and permits (NYC DOB: Do I Need a Permit?). That includes structural work, new walls or removing walls, changes to exits, new or enlarged buildings, most electrical work, plumbing work that alters or relocates piping, and anything that changes the building’s use or occupancy. The rules come from the city’s construction codes, last comprehensively revised by Local Law 126 of 2021, which applies to applications filed on or after November 7, 2022 (DOB: 2022 construction codes overview).
What work does not need a permit?
Minor alterations and ordinary repairs, under Administrative Code § 28-105.4.2. The department’s own examples are:
| Work | Permit? | Note |
|---|---|---|
| Painting and plastering | No | Minor alteration or ordinary repair (AC 28-105.4.2) |
| Installing new kitchen cabinets | No | The contractor still needs a DCWP Home Improvement Contractor license |
| Resurfacing floors | No | The contractor still needs a DCWP Home Improvement Contractor license |
| Replacing plumbing fixtures | No | Ordinary plumbing work by a Licensed Master Plumber (AC 28-105.4.4) |
| Non-structural roof repair | No | Minor alteration or ordinary repair |
| Mechanical service equipment work listed in 1 RCNY 101-14, Table 2 | No | Only the equipment work that table lists |
Not needing a permit does not mean anyone can do the work. Ordinary plumbing maintenance and repair, including allowable replacement or relocation of plumbing and gas piping, must still be done by a Licensed Master Plumber, and electrical work has its own permit rules; see the NYC electrical code guide and NYC plumbing and gas rules.
What about emergencies?
Under Administrative Code § 28-105.4.1, emergency work is work that would require a permit but is performed to relieve an emergency condition. A licensed contractor may start before a permit is issued, but must file an Emergency Work Notification within two business days after the work is completed. The department’s examples include erecting sidewalk sheds or fences to protect the public, stabilizing unsafe structural conditions, repairing gas leaks, replacing parts of combined standpipe and sprinkler systems, and repairing or replacing heating or hot water equipment serving residential occupancies during the heating season.
Who is allowed to do the work?
Many trades are licensed by the Department of Buildings, including master electricians and master plumbers. Separately, the Department of Consumer and Worker Protection licenses home improvement contractors: anyone doing construction, repair, remodeling or other home improvement work on residential land or buildings in the city needs that license (DCWP: Home Improvement Contractor). DCWP notes that many home improvements also need a DOB permit, and sidewalk work needs a Department of Transportation permit.
What should an owner do before work starts?
- Ask the contractor whether the job needs a permit, and which section of the code they are relying on if they say it does not.
- Check the contractor’s license with the agency that issued it.
- Look up the property in DOB NOW to confirm the permit was issued before work begins.
- Keep the permit, inspection sign-offs and any certificate of occupancy changes with the building’s records.
