NYC DOB License Search & DCWP Contractor Lookup

Choose the right NYC contractor lookup

There is no single New York City search that answers every contractor question. Start with the claim you need to check:

For a structured, dated DCWP result, the NYC Open Data issued-licenses dataset can help you save the fields you matched. Use the live DCWP search again when you need current status.

Older pages and documents may call DCWP the Department of Consumer Affairs or use the abbreviation DCA. A number ending in -DCA can still appear in an active DCWP record; match the number and current status rather than rejecting it because of the legacy suffix.

Collect the identity before you search

Ask for the exact legal business name, any trade name used in advertising, the DCWP Home Improvement Contractor number, the business address, and the phone number that will appear on the contract. A truck, proposal, and website may use a shorter brand name while the official record uses a corporation or LLC name.

The purpose of collecting these fields is not paperwork for its own sake. It prevents a search result for a similarly named company from being mistaken for the contractor who gave you the quote. Follow the contractor-name matching checklist to compare the proposal, trade name, legal entity and agency identifiers.

Search and match the official record

DOB license search: use DOB NOW Licensee

1. Open the official DOB NOW public portal and choose Licensee.
2. Select the license or registration type that applies to the contractor's claim. Use DOB's public-portal search instructions if you are unsure which record to choose.
3. Search by business name or license number. Match the returned business and identifier to the exact entity on the proposal.
4. Read the status and available insurance details in the returned record. Save the date and source; a DOB registration is not a DCWP Home Improvement Contractor license.
5. For work at a particular address, continue separately to DOB job and permit records. A license search alone does not establish that this company performed a particular project.

DCWP contractor lookup: match the HIC record

Open the official DCWP business search. Search first by license number when one is available, then by legal name. Compare:

• the license category;
• legal business name;
• license number;
• status and expiration date;
• business address;
• any details that help distinguish the company from a namesake.

If the proposal uses a trade name, check the New York State Department of State entity database for a corporation or LLC and any assumed-name filing that helps connect the names. The Department of State warns that its database relies on filed information and does not guarantee completeness or accuracy, so treat it as one identity source rather than a universal certification.

Read status and dates correctly

A matched active result is evidence that the listed license existed with the displayed status on the day you checked. It is not a rating, a workmanship warranty, or proof that the company is qualified for every type of exterior work.

An expired result is also a dated fact. It should lead to a current-status check and a request for clarification. A not found result means the searches you ran did not return a reliable match; it does not prove that no license exists under another legal name. An unavailable portal is a failed check, not a negative result. Use the not-found, unavailable and not-checked definitions to record which situation occurred and the next search to run.

There is a second question: does this particular contract require a DCWP Home Improvement Contractor license? DOB's Home Improvement Contractor Permit Requirements page explains an exemption for work in a multiple dwelling when the contractor is hired by the building owner or board. Do not use that exemption to excuse every missing result, or apply a one- or two-family-home rule to a co-op or apartment building. Record the building type, hiring party, scope, and exact contracting entity, then confirm the requirement for the job. A DOB registration or permit history is useful evidence, but it is not the same as a DCWP HIC license.

Read what an expired HIC result means before drawing a conclusion from that status.

Continue beyond the license

A license check answers one question. Continue with the records relevant to the proposed work:

1. Search DOB NOW and BIS for permit history under the company name or license identifier.
2. Check whether the quoted entity appears consistently in the New York business-entity record.
3. Follow the contractor insurance and COI checks: ask for current documents, match the named insured to the contracting entity, and verify them with the issuing party when appropriate.
4. Review workers’ compensation coverage or a legitimate exemption without assuming that every business structure has the same requirement.
5. For covered pre-1978 renovation work that disturbs paint, review EPA lead-safe firm certification.
6. Compare claimed projects with address-specific public records while remembering that an unmatched project is not proof the work did not happen.

Our complete contractor-vetting guide puts those checks in a practical order.

Save a dated record

Save the URL, the fields you matched, the date of the check, and a copy of the proposal or contract version you compared. Public records change: licenses renew, policies end, addresses are amended, and portal data is corrected.

Use the current official record again shortly before signing and before work begins. If a mismatch remains, ask the contractor to identify the legal entity and record that should apply. Do not silently substitute a close-enough company name.

Is a DOB lookup the same as a contractor-license lookup?

No. DOB licenses or registers certain construction trades and maintains building job and permit records. DCWP issues the Home Improvement Contractor license used for covered residential home-improvement work. Depending on the scope, the same business may need a DCWP record, a DOB license or registration, or appropriately licensed subcontractors.

Can I search by license number?

Yes. A license number is usually the cleanest starting point because business names vary in punctuation and spacing. Still compare the returned legal name, category, address, status, and expiration date with the proposal. A number copied from another business is not a match.

What if the contractor does not appear?

Repeat the search with the legal name, trade name, abbreviations, and number without punctuation. Check that you used the correct agency and record type. If no reliable match appears, record the terms and date, ask the contractor for the exact licensed entity, and describe the result as not found in the searches performed—not as proof that no license exists.
