HOMEOWNER CHECKLIST · NYC + NEW JERSEY
How to check a contractor in NYC or New Jersey before hiring
Use official lookup tools, match the business on your estimate, and record the answers before committing to a project.
Start with the exact business details
Ask for the business name, address, relevant license or registration number, and the name that will appear on your contract. Search those details yourself rather than relying on a screenshot. Save the date and result of your check. A lookup is one check, not a guarantee of workmanship.
New York City: choose the right lookup
For home improvement businesses, start with NYC DCWP’s official license checker. NYC has separate credential checks for different types of work. For plumbing and electrical projects, use the Department of Buildings license and registration resources; do not treat a general home improvement record as proof of a trade-specific credential.
For estimate and contract questions, read DCWP’s homeowner hiring guidance. If the property is outside NYC, check the relevant local authority rather than assuming NYC rules apply.
New Jersey: check the business and the work
Start with the New Jersey Division of Consumer Affairs verification page. Choose the search category appropriate to the business or professional and the proposed work. Use the official home improvement contractor resources for current guidance. Registration and trade licensing are different checks; confirm which applies to your project.
Five questions before you sign
- Does the name in the official record match the business proposing the work? Resolve differences before paying.
- Can the contractor provide insurance information, and can you verify it with the insurer?
- Is the scope written clearly, including exclusions, materials and cleanup?
- Who will confirm permit requirements with the local building department and handle any required permits?
- What happens if the scope changes, the schedule slips or warranty work is needed?
Keep your project file together
Keep estimates, lookup results, insurance documents, written changes, receipts and warranty terms in one place. Ask the relevant authority about unresolved credential questions. This guide helps you organize checks; it does not certify a contractor or replace project-specific professional advice.
