What Are DC's Contractor Licensing Rules?

Is a contractor license required in DC?

Yes, and because DC is a single consolidated jurisdiction rather than a state with cities and counties underneath it, there's no local-versus-state question to untangle — one agency licenses everything. General Contractor and Construction Manager work is licensed as a business category, and Home Improvement Contractor work — repair or remodeling on an existing residence — is a separate business license with its own bonding and consumer-protection requirements. Electrical, plumbing/gasfitting, and HVAC/refrigeration work are regulated differently from either of those: each requires both an individual occupational license (journeyman or master level) and a separate trade-contractor business license. DC passed a law in 2024 that would create a genuinely new, exam-based General Contractor licensing system with its own board and a consumer guaranty fund, but that law's substantive provisions are marked "not funded" in the DC Code and haven't been implemented — the General Contractor license that actually exists today remains the older, simpler basic business license, not the new system.

Which agency regulates it?

The Department of Licensing and Consumer Protection (DLCP) — renamed from DCRA — handles all of it, but through two different internal tracks. General Contractor and Home Improvement Contractor licensing runs through DLCP's general business licensing system, now processed through its BOSS portal. Electrical, plumbing/gasfitting, and HVAC/refrigeration licensing runs through DLCP's Board of Industrial Trades, which issues the individual journeyman and master credentials and processes trade-contractor business applications separately. DLCP publishes both tracks' current licensing instructions directly.

Where can you find the actual laws?

General business and occupational licensing sits in DC Code Title 47, Chapter 28 — home improvement licensing and bonding authority is § 47-2883.01, and the new, not-yet-funded General Contractor professional licensing system is §§ 47-2853.78 through 47-2853.78i. Home improvement business regulations, including the rule against taking payment before work is complete, are in 16 DCMR Chapter 8. DC Code § 2-135 sets out plumbing compliance penalties. The Board of Industrial Trades' own published instructions govern the practical details of trade-contractor licensing and aren't all separately codified section by section. The Board of Industrial Trades publishes the electrical, plumbing, and HVAC licensing requirements directly.

What does it take to get licensed?

A General Contractor business license requires liability insurance, business and tax registration, and occupancy documentation. A Home Improvement Contractor license requires all of that plus a $25,000 surety bond, a sample contract, and a criminal history report, and the business has to designate a licensed Home Improvement Salesperson — a consumer-facing sales credential, not a technical qualification, and not the same kind of role as a master electrician or plumber. Electrical, plumbing/gasfitting, and HVAC/refrigeration work differently: an individual works up through journeyman (roughly four years and 8,000 hours) to master (roughly eight years and 16,000 hours) with an exam at each level, and a business then separately applies for a trade-contractor license by designating a DC-licensed master tradesperson as its qualifier — that master has to personally accept the designation through their own licensing account. Both the company and the designated master post their own separate surety bonds, with amounts that vary by trade (electrical and low-voltage work carry smaller bonds than plumbing, gasfitting, or refrigeration). There's no additional exam at the business-license stage — the competency exam belongs entirely to the individual's journeyman or master license.

What are the penalties for operating without a license?

Mostly administrative and civil rather than criminal. DLCP treats unlicensed contracting — particularly unlicensed home improvement work — as a potential violation of DC's Consumer Protection Procedures Act, which can bring fines and suspension or revocation on top of whatever licensing action follows. Unlicensed activity generally qualifies as a Class 1 civil infraction, which carries a substantial fine well over $2,000 for a first offense under DLCP's own published fine schedule. Separately, DC Code § 2-135 sets out an older, narrower criminal penalty specifically for failing to comply with plumbing regulations after notice — a fine of up to $200, up to 30 days in jail in default of payment, or both — though that provision shouldn't be read as the universal penalty for unlicensed contracting generally. DC courts have also held that accepting payment in advance of completed work, without the required home improvement license, violates 16 DCMR § 800.1, which can affect whether that contract is enforceable at all. The 2024 law's proposed $50,000 consumer guaranty fund for General Contractor work isn't operational — it exists on paper but hasn't been funded.

Does DC have reciprocity with other jurisdictions?

Yes, with its immediate neighbors, though more developed for electrical than plumbing. DC recognizes both journeyman and master electricians licensed in Maryland or Virginia without requiring them to retake the DC exam, as long as the original license was earned by examination and is current and in good standing — reciprocity waives the exam, but a DC license still has to be obtained, it isn't automatic. Plumbing reciprocity is newer and narrower: DC has recently opened a reciprocity pathway specifically for Maryland-licensed plumbing professionals, though the Board hasn't published the full eligibility terms for which license grade qualifies. There's no confirmed reciprocity pathway for Virginia plumbing or HVAC/refrigeration credentials.

Is it legal to rent or lease a license in DC?

For electrical, plumbing/gasfitting, and HVAC/refrigeration, DC builds a real, actively administered relationship into the trade-contractor license rather than a one-time paper designation. The business has to designate a DC-licensed master, and that person has to personally accept the designation through their own licensing account — it isn't something a company can do unilaterally by listing someone's license number. That master is responsible for supervising the actual work and personnel on the company's projects. DLCP runs a formal Designated Master Transfer Request process for when that relationship changes, which confirms the department treats this as a real, trackable affiliation rather than a static filing. What DLCP's published instructions don't spell out is whether the designated master has to be an owner or a W-2 employee specifically, or whether the same master can be designated for more than one trade-contractor business at the same time — those details aren't resolved one way or the other in what the Board has made public. For General Contractor and Home Improvement Contractor licensing, there's no equivalent qualifying-master system at all — the Home Improvement Salesperson requirement is a separate, lower-bar credential and shouldn't be treated as an equivalent relationship.
