Research contractors in New York City: profiles, credentials and permits.
Start with the exact business and the work you need. In NYC, a home-improvement license, a trade credential and a project permit answer different questions. Compare dated company research, then confirm current requirements for your address and scope with the relevant City agency before signing.
Local guidance checked October 16, 2026. Company research dates are shown below and are not refreshed by this guide.

Choose the right credential check
Home-improvement work
DCWP’s June 2026 hiring guidance describes the Home Improvement Contractor license for covered residential work costing more than $200. Its home-improvement definition excludes new-home construction, plumbing and purely electrical work. Check the category that actually applies to your project.
Plumbing and electrical professionals
A home-improvement license alone does not establish a plumbing or electrical credential. Use the Department of Buildings’ Find Licensed Professionals guidance to check the relevant professional’s current license status and disciplinary or voluntary-surrender record. NHA has not performed an individual City license check for the examples on this page.
Permit-exempt is not credential-exempt
DOB’s Do I Need a Permit? page explains that certain minor work may not need a work permit, while other laws and professional requirements still apply. It specifically identifies ordinary plumbing work that must be done by a Licensed Master Plumber even when a permit is not required.
Do not infer a blanket exemption from a project label such as “repair.” Ask DOB or the appropriate licensed professional about the exact scope, building and address before work begins. Building-management approval and access arrangements may be separate project questions.
Get the scope and permit responsibilities in writing
For applicable home-improvement contracts, DCWP explains that written permit disclosure should identify required permits, who obtains them, the process, estimated fees and how status can be checked. Its guidance also links sample estimate, contract, cancellation and change-order documents.
Compare the same work: materials, exclusions, schedule, payments and warranty terms. For an electrical project, identify the equipment and proposed change; for plumbing, separate fixture work from piping or heating work; for HVAC, identify repair versus replacement and associated electrical or plumbing scope.
New York City includes the Bronx, Brooklyn, Manhattan, Queens and Staten Island. A nearby Nassau or Westchester office is not an NYC office. Confirm who will serve your actual address, manage permits and coordinate building access.
Read dated evidence, then make your own shortlist.
Gold recognition uses an exact BBB A+ record, directly verifiable Google customer rating strictly above 4.3, identity matching, official services and complaint-context review at the profile’s research date. Historical or special-recognition profiles explain their own basis. Ratings and records can change.
For plumbing-specific license checks, permit scope, condo/co-op coordination and final sign-off, use the NYC plumbing research guide.
NHA has not independently verified current licensing, bonding, certifications or insurance for the companies included here. A rating is not a credential or a guarantee of safety, workmanship or results. Verify credentials and insurance for your particular work before hiring.
Use the research standards, company directory and national contractor-research hub. Contact companies through their public channels; this guide requires no lead form. NHA is a private information resource, not a City agency. Any advertisements or material relationships remain separately disclosed.
