Emergency? Gas smell, CO alarm, fire, sparking or flooding: get to safety and call 911 first.
Which license does the job need?
- General repairs and renovation (carpentry, drywall, roofing, gutters, windows, flooring, kitchens and baths) costing more than $200: a DCWP Home Improvement Contractor (HIC) license.
- Plumbing and gas piping: a DOB Licensed Master Plumber. DCWP notes that home improvement work doesn't include plumbing.
- Electrical: a DOB licensed master electrician. Purely electrical work isn't home improvement work either.
- Locksmiths: licensed by DCWP (moving to a business license on May 31, 2027).
- Painting only: NYC's home improvement definition excludes painting and decorating that isn't related to other improvement work.
Check a DCWP license (home improvement, locksmith)
- Go to the DCWP license search. No account needed. You can also call 311.
- Search by business name or DCWP license number.
- Confirm it's active and that the name matches the company you're signing with.
- For complaint history, call 311 and say "Business Background Check."
Why it matters: if a DCWP-licensed home improvement contractor owes you money, you may be eligible for reimbursement from the Home Improvement Contractor Trust Fund. With an unlicensed contractor, you're not.
Check a DOB license (plumber, electrician)
- Go to the DOB NOW Public Portal and choose Licensee. The search includes both DOB NOW and older BIS records.
- Search by last name, business name or license number, and pick the license type.
- Check the license status and the insurance information shown.
- DOB also offers a "Know Your Construction Professional" directory with disciplinary records.
Other red flags
- No written estimate, or a refusal to put the price and scope in writing. DCWP says licensed home improvement contractors must give you a written estimate if you ask.
- A large cash deposit demanded up front.
- "We don't need a permit" for gas, electrical or structural work.
- A license number that belongs to a different company name.
Our pro signup asks businesses for their license details, but you should always verify a license yourself before work starts.
