How to Check a Contractor's License in Washington DC

Washington DC requires contractors to be licensed before performing construction work in the District. The licensing is handled by the Department of Licensing and Consumer Protection (DLCP), which was formerly known as the Department of Consumer and Regulatory Affairs (DCRA). The agency rebranded in recent years, so you may still see references to DCRA in older materials, but the licensing functions remain the same.

This guide covers how DC's contractor licensing system works, how to search the license verification database, what the different license types mean, and what else you should verify before hiring a contractor in the District.

Does Washington DC require a contractor license?

Yes. DC requires all contractors to hold a Basic Business License with a construction endorsement issued by the Department of Licensing and Consumer Protection. License types include General Contractor Class A (unlimited), General Contractor Class B, Home Improvement Contractor, and various specialty contractor licenses. Hiring an unlicensed contractor in DC means losing access to the Home Improvement Guaranty Fund if something goes wrong.

The District of Columbia requires contractors to hold a Basic Business License (BBL) with a construction endorsement to legally perform construction work. The BBL is the general business license required for all businesses operating in DC, and the construction endorsement is the specific authorization to perform contracting work.

DC issues several types of contractor licenses based on the scope of work:

• General Contractor (Class A)— Authorized to perform any type of construction work without a dollar limit. This is the highest level of contractor license in DC.
• General Contractor (Class B)— Authorized to perform construction work on projects up to a specified dollar amount, typically lower than the unlimited Class A license.
• Home Improvement Contractor— Specifically for residential renovation, repair, and improvement work. This is the most common license type for homeowners hiring a contractor for residential projects.
• Specialty Contractor— Licensed for a specific trade or type of work, such as electrical, plumbing, HVAC, or excavation.
• Electrical Contractor— Specifically authorized to perform electrical installation and repair work.
• Plumbing Contractor— Specifically authorized to perform plumbing installation and repair work.

Each license type has its own requirements for experience, bonding, and insurance. Some license types also require passing an examination.

How do I look up a contractor's license in DC?

Use the DC Business License Verification tool at eservices.dcra.dc.gov/BBLV to search by business name, owner name, license number, or address. The results show license type, status, issue date, and expiration date. Confirm the license is active, matches the type of work you need, and has not expired. DC licenses must be renewed every two years.

DC provides an online tool for verifying contractor licenses. Here is how to use it:

1. Go to the DC Business License Verification page. Note that while this URL still uses the DCRA domain, it serves the same function under the new DLCP.
2. You can search by business name, owner name, license number, or address. Enter the information you have and click search.
3. Review the results. The listing will show the license type, status, issue date, expiration date, and the business address.

You can also use the Department of Licensing and Consumer Protection main website to navigate to the license search tool and find additional information about licensing requirements.

When reviewing the search results, check for the following:

• License status. It should show as active. An expired, suspended, or revoked license means the contractor is not authorized to work in DC.
• License type. Make sure the license type matches the work you need done. A home improvement contractor license does not cover new commercial construction. A specialty contractor license does not cover general contracting work.
• Expiration date. DC business licenses must be renewed every two years. An expired license is not valid.
• Business name and address. Confirm the information matches the contractor you are dealing with. Contractors sometimes operate under multiple business names or entities.

Do electricians and plumbers need separate licenses in DC?

Yes. Electricians must hold both an electrical contractor license and individual journeyman or master electrician licenses. Plumbers must hold a plumbing contractor license and individual journeyman or master plumber licenses. HVAC contractors need a refrigeration and air conditioning contractor license. All of these can be verified through the same DC license verification database.

In addition to the general contractor and home improvement contractor licenses, DC requires separate licenses for several specialty trades.

Electricians must hold an electrical contractor license to perform electrical work in DC. Individual electricians are also required to hold a journeyman or master electrician license. These are separate from the business license and verify that the individual has the technical qualifications to perform electrical work safely.

Plumbers must hold a plumbing contractor license, and individual plumbers must hold journeyman or master plumber licenses. Similar to electricians, these licenses verify technical competence through examinations.

HVAC contractors need a refrigeration and air conditioning contractor license to install and service heating, ventilation, and air conditioning systems.

All of these specialty licenses can be verified through the same DC license verification database. If your project involves specialty trade work, check both the contractor's general business license and the specific specialty trade license.

What are DC's bonding and insurance requirements for contractors?

General contractors must post a bond of $25,000 or more depending on license class. Home improvement contractors must post a bond of $5,000 to $25,000. All contractors must carry general liability insurance at minimums set by the District. Insurance policies can lapse between renewals, so always request a current certificate and verify it directly with the carrier.

DC requires contractors to post a surety bond as part of the licensing process. The bond amount varies by license type:

• General contractors are required to post a bond of $25,000 or more depending on the class.
• Home improvement contractors are required to post a surety bond, typically $5,000 to $25,000.
• Specialty contractors have varying bond requirements based on the trade.

Contractors must also carry general liability insurance. The minimum coverage amounts are set by the District. While the licensing process verifies insurance at the time of licensure and renewal, insurance policies can lapse between renewals. Ask the contractor for a current certificate of insurance and verify it directly with the insurance carrier.

Workers' compensation insurance is required for contractors with employees under DC law. You can verify workers' compensation coverage through the DC Department of Employment Services.

What is DC's Home Improvement Guaranty Fund?

DC's Home Improvement Guaranty Fund allows homeowners to recover money if a licensed home improvement contractor fails to perform work, performs defective work, or breaches the contract. This protection only applies when you hire a contractor with a valid DC home improvement contractor license—hiring an unlicensed contractor means you have no access to this fund and must rely solely on civil court.

DC has specific consumer protections for residential home improvement work. The Home Improvement Guaranty Fund provides a mechanism for homeowners to recover money if a licensed home improvement contractor fails to perform work, performs defective work, or otherwise breaches the contract. This fund only applies to work performed by contractors who hold a valid DC home improvement contractor license.

This is one of the practical reasons why hiring a licensed home improvement contractor in DC matters. If you hire an unlicensed contractor and something goes wrong, you do not have access to this fund. Your only recourse would be through the courts.

What else should I verify before hiring a contractor in DC?

Beyond the license database, check the DC Office of the Attorney General for complaints, confirm the license type matches your specific project scope, verify building permits will be pulled, ask for references from recent DC-area projects (particularly relevant given historic district requirements), and review the written contract for DC consumer protection compliance.

Beyond checking the license in the DC verification database, here are other important steps:

• Check for complaints and enforcement actions. Contact the DC Office of the Attorney General's Consumer Protection division to check for complaints filed against the contractor. You can also check with DLCP directly for any enforcement actions or violations.
• Verify the specific license covers your work. A contractor may hold a valid license but for a different type of work than what you need. A plumbing contractor license does not authorize general construction work, and vice versa.
• Confirm building permits will be pulled. DC requires building permits for most construction projects. The contractor should be able to pull permits under their license. Work done without permits violates DC law and can create problems with inspections and property sales.
• Check references.Ask for references from recent projects in the DC area. DC has unique building characteristics — row houses, historic district requirements, and older building infrastructure — so experience working in the District is particularly relevant.
• Review the contract. DC law has specific requirements for home improvement contracts, including cancellation rights. Make sure you have a written contract that complies with DC consumer protection requirements.

Common issues in DC

The DCRA-to-DLCP transition.The rebranding from DCRA to the Department of Licensing and Consumer Protection has caused some confusion. Older license documents, permits, and references may still use the DCRA name. The licenses themselves are still valid — the underlying licensing program has not changed, just the agency name.

Historic district requirements. Many areas of DC fall within historic districts that have additional requirements for construction work. If your property is in a historic district, the contractor may need to follow specific guidelines from the Historic Preservation Office. Make sure the contractor is familiar with these requirements if they apply.

Unlicensed contractors. Despite the licensing requirement, some contractors operate in DC without proper licensing. This is a violation of DC law and exposes you to significant risk. Always verify the license before hiring, and be cautious of contractors who offer unusually low prices or resist providing their license information.

The bottom line

Washington DC requires contractors to hold a Basic Business License with the appropriate construction endorsement, issued by the Department of Licensing and Consumer Protection. You can verify a contractor's license online through the DC license verification database. Make sure the license is active, matches the type of work you need, and has not expired. For specialty trade work, check the specific trade license in addition to the general business license. Verify insurance and bonding independently, check for complaints with the Attorney General and DLCP, and confirm the contractor will pull proper building permits. DC's licensing system provides meaningful consumer protections, including the Home Improvement Guaranty Fund, but those protections only apply when you hire a properly licensed contractor.
