Washington D.C. Contractor Licenses: Updated Requirements Guide
Contracting in Washington D.C. is centrally regulated at the District level. Most building and trade activities require a Basic Business License through the Department of Licensing and Consumer Protection (DLCP), and technical trades are licensed by the DLCP Board of Industrial Trades. Whether you manage full-scope construction or specialize in a single system, plan on obtaining the correct District-issued license before bidding or performing work.
The DLCP Business Licensing Division administers the General Contractor (A, B, C, G & H)/Construction Manager license and the Home Improvement Contractor and Salesperson licenses. The Board of Industrial Trades licenses electricians, plumbers and gasfitters, refrigeration and air conditioning (HVAC) mechanics and contractors, asbestos workers, elevator mechanics and inspectors, and steam and other operating engineers. We highlight several representative licenses and authorities for Washington D.C. below; this guide is updated periodically as additional details are clarified or requested.
DLCP offers an online Business Licensing Portal (Access DC/DC Business Center) for applications and renewals, and most industrial trades use third-party examinations where applicable. Because District rules evolve, always verify current forms, fees, required documents, and insurance minimums on the official DLCP site before applying.

Overview of Washington D.C. Contractor Licensing
Washington D.C. licensing is administered by the Department of Licensing and Consumer Protection (DLCP). The Business Licensing Division issues Basic Business Licenses (BBLs) for construction business activities, including General Contractor (A, B, C, G & H)/Construction Manager and Home Improvement Contractor and Salesperson. DLCP’s DC Business Center provides online applications, checklists, and step-by-step guidance for required filings such as tax registration and Clean Hands certifications.
Technical and high-risk trades are regulated by the DLCP Board of Industrial Trades. The Board licenses electricians and electrical contractors, plumbers and gasfitters, refrigeration and air conditioning mechanics and contractors, asbestos workers, elevator mechanics and inspectors, and steam and other operating engineers. Examinations for electrician, plumber/gasfitter, and refrigeration/air conditioning categories are administered by PSI under contract with the Board of Industrial Trades.
The D.C. Council enacted the General Contractor Licensing Amendment Act of 2024 (D.C. Law 25-244), which creates a Board of Construction Managers and General Contractors and reinforces DLCP’s regulatory framework for general contracting in the District. All contracting entities must maintain current BBLs and, where applicable, employ District-licensed trade professionals when projects include regulated systems.

Application Process
- Complete the four core steps to obtain a Basic Business License: (1) business registration (Corporations Division if applicable), (2) tax registration with the DC Office of Tax and Revenue, (3) obtain a Certificate of Occupancy or Home Occupation Permit if operating from a DC location, and (4) obtain a Certificate of Clean Hands. See the DLCP Business Licensing Division overview at https://dlcp.dc.gov/service/business-licensing-division.
- Choose the correct business license category for your scope: General Contractor (A, B, C, G & H)/Construction Manager, Home Improvement Contractor, and/or Home Improvement Salesperson, per DLCP’s Contractor and Construction Services guidance.
- For industrial trades (electrician, plumbing/gasfitting, refrigeration and air conditioning, asbestos, elevator, steam/operating engineers), apply through the Board of Industrial Trades online system and meet documented experience, training, and examination requirements.
- Prepare supporting documents per category: liability insurance certificates, surety bonds (e.g., for home improvement and certain trade contractors), sample contracts, criminal history reports (where required), and salesperson designation letters.
- Submit applications and fees via the DC Business Licensing Portal (Access DC/DC Business Center) or in person at 1100 4th Street, SW. Links and instructions are available from the DLCP Business Licensing Division page.
- Maintain compliance post-approval: renew on schedule, keep insurance and tax registration current, and ensure that subcontractors and specialty trades on your projects hold required DC trade licenses.
Timeline: Mail-in applications for General Contractor/Construction Manager may take up to 30 days to process; online submissions via the DC Business Center are noted as having faster turnaround times.
Reciprocity
Reciprocity varies by trade and is limited. Some electrical arrangements involving nearby jurisdictions (e.g., Maryland and Virginia) may exist in specific circumstances, but most contractors must complete Washington D.C.’s own application process. Verify any reciprocity pathway directly with DLCP and the Board of Industrial Trades before relying on it.
Frequently Asked Questions
How long does it take to get a contractor license in Washington D.C.?
Processing depends on license type and application method. Mail-in General Contractor/Construction Manager applications may take up to 30 days; online submissions via the DC Business Center typically move faster. Trade licenses also depend on exam scheduling and document review.
Do I need both a Basic Business License and a trade license?
Yes, when your business offers regulated trade services. For example, an electrical contracting company needs a DC Electrical Contractor license tied to a DC Master Electrician and also must maintain the appropriate Business License and business compliance items (insurance, tax registration, Clean Hands, etc.).
Can I transfer my license from another state to Washington D.C.?
Limited reciprocity may exist for certain trades in narrow circumstances, but most applicants must meet DC’s requirements and follow DLCP’s application process. Confirm any reciprocity pathway with DLCP and the Board of Industrial Trades before applying.
What exams are used for DC trade licenses?
PSI administers DC exams for Electrician, Plumber/Gasfitter, and Refrigeration and Air Conditioning categories under the Board of Industrial Trades. For other specialties (e.g., elevator, asbestos, steam/operating engineers), consult DLCP for the current examination process and references.

Yes, many categories require insurance, and several contractor classifications require surety bonds. Examples include liability insurance for General Contractor/Construction Manager and Home Improvement Contractor BBLs, specified minimums for home improvement, and bonding for various trade contractors. Check DLCP’s current requirements for your exact license type.
How do I renew my license?
Renew through the DC Business Center (for BBLs) and DLCP’s online system (for industrial trades) on the timelines set by DLCP and the Board of Industrial Trades. Keep insurance, bonds, and tax registrations continuous and updated.
What happens if I fail a trade exam?
