DC Masonry Contractor License Requirements (2026)

The District of Columbia does not issue a standalone masonry license. Masonry contractors performing work in DC must hold a DC Basic Business License (BBL) under the General Contractor / Construction Manager endorsement issued by the DC Department of Licensing and Consumer Protection (DLCP, formerly DCRA) under D.C. Code §47-2851. The DLCP requires Clean Hands Certification (no outstanding DC tax debt), Certificate of Occupancy or home occupation permit, and proof of insurance. There is no DC trade exam for masonry. This page documents the verified path including DC OSHA silica enforcement and TMS 402 / IBC Chapter 21 compliance.

Regulatory Oversight

This license is issued and enforced by District of Columbia Department of Licensing and Consumer Protection — Board of Industrial Trades (DLCP) pursuant to D.C. Official Code Title 47 Chapter 28 (Basic Business License); D.C. Municipal Regulations Title 17 (Business, Occupations, and Professionals). DLCP (formerly DCRA) issues the Basic Business License (BBL) including the Home Improvement Contractor endorsement, and staffs the Board of Industrial Trades which licenses master and journey electricians, plumbers, steamfitters (HVAC), and refrigeration and air-conditioning mechanics in the District of Columbia.

Good moral character

DLCP requires Clean Hands Certification — no outstanding DC tax obligations or unpaid fees.

Background investigation

Self-disclosure on the BBL application; no fingerprinting for the masonry endorsement.

Required Experience and Education

Insurance carriers and prime contractors require demonstrated journey-level masonry experience by contract..

Accepted proof of experience or eligibility

Optional: signed letters from prior masonry employers
Project list (used for prime subcontracts and underwriting, not the BBL)

Examination Requirements

Rather than a written state examination, the cited materials route this credential through: No exam required by DC DLCP for the masonry / GC BBL

Examination fee: No exam fee — DC BBL is administrative.

Insurance and Financial Requirements

The cited state source set does not require a contractor license surety bond for this credential. Contractors should still confirm project-specific bond, permit-bond, or public-works bond requirements before bidding.

General liability

DC DLCP requires GL disclosure on the BBL application. Most owners and DC government contracts require $1,000,000 per occurrence / $2,000,000 aggregate.

Workers' compensation

Workers' compensation is mandatory under D.C. Code §32-1503 for any DC employer with one or more employees. Masonry NCCI 5022 carries one of the highest manual rates in DC.

Additional financial requirements

No financial statement required. Clean Hands Certification (DC tax compliance) is mandatory at every BBL application and renewal.

Licensing Fees

Fee	Amount
Application (non-refundable)	$258
Initial license	$258

Keeping the License Current

Renewal of the DC General Contractor / Construction Manager License (Masonry Subtrade) — DLCP comes due every 2 years. As cited, the renewal fee stands at $258. DC Basic Business Licenses renew every two years. Late renewal incurs a 10% penalty plus possible BBL suspension.

Reciprocity and License Transfer

Application Process, Step by Step

Form an entity and register with DLCP Corporations. File LLC/corporation registration with DC Corporations Division; out-of-state entities qualify as foreign.
Obtain a Certificate of Occupancy or Home Occupation Permit. DC requires CofO or HOP for the business address before BBL issuance.
Obtain Clean Hands Certification. Verify no outstanding DC tax debt or fees through MyTax.DC.gov.
Bind GL and workers compensation. Bind GL ($1M+ practical) and workers comp for any employees before applying.
Submit DLCP BBL application. File the General Contractor / Construction Manager BBL application with $208 + $50 endorsement fee through MyDC Business Center.
Receive BBL and post on jobs. DLCP issues the BBL number; it must appear on all DC contracts and bids per D.C. Code §47-2851.
Implement OSHA silica program. Federal OSHA enforces 29 CFR 1926.1153 in DC; written exposure control plan and Table 1 controls are mandatory.

Frequent Application Errors

Working from the cited board instructions, here are the snags most likely to trip up a District of Columbia Masonry filing.

Clean Hands failure at renewal

Any outstanding DC tax debt — even $50 — blocks BBL renewal until cleared. Common surprise for contractors with unpaid sales/use tax.

Historic district mortar mismatch

Georgetown and Capitol Hill HPO requires Type O lime mortar for pre-1920 masonry. Using Type N or S Portland cement causes immediate stop-work orders and remediation costs.

Working without CofO

BBL applications without Certificate of Occupancy or Home Occupation Permit are rejected. Out-of-DC contractors often miss this requirement.

Anchored veneer ties wrong gauge

DC wind and freeze-thaw require corrosion-resistant ties at TMS 402 spacing; DOB inspectors fail jobs with undersized or missing ties.

Silica plan absent

Federal OSHA targets DC masonry sites; missing 29 CFR 1926.1153(g) plans draw immediate citations.

Document Checklist

These are the pieces to lock down before filing with DLCP:

☐ DC Corporations Division entity registration
☐ Certificate of Occupancy or Home Occupation Permit
☐ Clean Hands Certification from MyTax.DC.gov
☐ GL insurance certificate ($1M+ practical)
☐ Workers compensation certificate
☐ DLCP BBL application + GC/CM endorsement ($258)
