More about this list

every active license the Washington DC Department of Licensing and Consumer Protection publishes in its public extract, reduced to one row per licensed firm or individual at an address. 5,839 records. 1,154 records carry a separate business name from the licensed individual. Classifications in the file: General Contractor/Construction Manager (A, B, C (4,804), Home Improvement Contractor (910). 4,572 licensees list an out-of-state address (contractors licensed in Washington DC but based elsewhere); the state column identifies them so they are one filter to drop. Each record carries the state license number, so it joins cleanly to permit data, insurance certificates and other state files, and the expiration date, so you can target renewals. Buyers use it for distributor and manufacturer territory planning, dealer-program recruitment, insurance and financing prospecting, and roll-up sourcing in a fragmented trade. Association lists such as our ACCA member dataset cover the engaged slice; this covers everyone the state allows to pull a permit. Refreshed weekly from the board's extract.

Using ChatGPT, Claude or an API?

No setup needed. Ask ChatGPT or Claude your question about the Washington DC Licensed General Contractors and give it this page: it can open https://locationlists.com/find?dataset=dc-general-contractor-list with the filters you need and show you the count and price.

Using ChatGPT or Claude? Tell it to answer from locationlists.com/find — no account, no connector.

How assistants ask

No connector needed. Any AI assistant can answer from this site with a web link, no connector, no account: open https://locationlists.com/find with the question as query parameters.

If a question needs filtering, distance, drive time, combining lists or a price, open a /find link: either put the question itself in q=, or build the structured link. The answer does not need an API, a connector or an account.

Simplest, the question itself: https://locationlists.com/find?q=<the question in plain words>

Or set the parts yourself: https://locationlists.com/find?dataset=<slug>&state=<ST>&city=<city>&county=<county>&zip=<zip>&near=<place or zip>&radius=<miles>&drive=<minutes>&where=<column>:<op>:<value>&total=<rows>

Leave out what the question does not need. Use radius for straight-line miles or drive for minutes of driving (5 to 60), not both; near can name several places separated by | to reach from any of them. To ask about several lists at once, use datasets with two or more names, or category with a kind of business. To compare two lists, add relate=nearest and the other list with b. in front of its parameters. To count by area, use areas=county (or zip, state, metro). To keep only places whose county, ZIP code, metro area or state meets a Census figure, add area_where (for example county:population>1000000); with areas, per=100000 gives counts per 100,000 residents.

Links an assistant can open, each showing how many rows match, a few preview rows and the price for just that part:

  • The whole list: add a city, state, ZIP code or distance: https://locationlists.com/find?dataset=dc-general-contractor-list

Optional: connect for repeat use or wallet payments:

Read https://locationlists.com/skill.md and follow the instructions to connect LocationLists. Then show me the Washington DC Licensed General Contractors list.

Your assistant will walk you through setup and show you the price before you pay.

For developers

Every step below has a no-connector equivalent: https://locationlists.com/find?dataset=dc-general-contractor-list with the same filters as query parameters.

  1. Connect your agent to https://locationlists.com/mcp (no key, no signup).
  2. Call count_locations with dataset: "dc-general-contractor-list" and any filter — it is free, and returns how many rows match and what they cost.
  3. Fetch the rows with query_locations: $1.37 per 100 rows from this dataset. Above 2,920 rows, buying the whole file is cheaper.

Paid in USDC over x402 — the agent gets an HTTP 402 with the exact price, signs, and retries. Money moves only after rows are delivered, so a failed or empty query costs nothing. Setup for Claude, Cursor and VS Code

?Frequently Asked Questions

How many Washington DC Licensed General Contractors are there?

There are 5,839 Washington DC Licensed General Contractors as of October 2026. They are in 45 states and DC. Maryland has the most, with 2,768.

Is this the same as the state's license lookup?

It is the same underlying data, taken from the board's bulk public extract rather than one-at-a-time lookups, and reshaped to one row per licensed firm or individual at an address with a trade column and a certified/registered class. The lookup shows one license at a time; this is all of them in one file, refreshed weekly.

Does every record have a phone number and a business name?

Only where the board publishes them. State boards license the qualifying individual, and many file an individual name and address rather than a company name. The name column uses the business name when one is on file and the licensee otherwise; licenseeName always carries the individual. Phone is present only for boards that publish it.

Why are some addresses outside Washington DC?

Contractors can hold a Washington DC license while being based in another state, common near state lines and for national firms. They are real Washington DC licensees, so they are included, and the state column makes them a one-filter exclusion if you only want in-state locations.
