DC Contractor Startup Checklist: Steps to Start a Contracting Business

Starting a contracting business in DC requires touching three separate agencies — DLCP, DOB, and OTR — in a specific order. Get the sequence wrong and you'll trigger Deficiency Notices, Clean Hands blocks, or application rejections that add weeks to your timeline. Here's the checklist that keeps the process moving forward without backtracking.

Step 1: Establish Your Business Identity

If you're operating under any name other than your exact legal first and last name, you need to register a trade name (DBA) through the BOSS portal at boss.dc.gov. The filing fee is $55, and the trade name must be renewed by April 1 of every second year following the initial registration year.

If you're forming an LLC instead of operating as a sole proprietor, file your Articles of Organization through the BOSS Corporations Division. The formation fee is $220.

At minimum, the corporate or registered trade name and physical business address on your Certificate of Insurance must match the BBL application exactly. Name mismatches are the single most common cause of Deficiency Notices.

Step 2: Secure Your Zoning Clearance

Before you can apply for a BBL, the Department of Buildings needs to confirm your business address is zoning-compliant.

Home-based contractors: Apply for a Home Occupation Permit (HOP) through the DOB Citizen Access Portal at citizenaccess.dc.gov. Cost: $72.60 total. You'll need your DC driver's license and a recent utility bill proving residency.

Commercial office or warehouse: Apply for a Certificate of Occupancy (COO) from DOB. Minimum filing fee: $36.30; final cost depends on square footage.

Based outside DC: If your business address is in Maryland or Virginia, both the HOP and COO are waived. You'll still need everything else on this list.

Step 3: Register with OTR (Form FR-500)

File the Combined Business Tax Registration (Form FR-500) at MyTax.DC.gov. This creates your District tax accounts — sales and use tax, personal property tax, and the unincorporated business franchise tax (if applicable).

You'll use your SSN or EIN to register. The form is free, but it activates tax filing obligations. Sole proprietors and single-member LLCs should be aware of the DC unincorporated franchise tax (Form D-30) — failing to file it, even when you qualify for an exemption, can create delinquencies that block your Clean Hands certificate.

While you're on MyTax.DC.gov, run a Clean Hands self-check. Under the current rules, you can owe up to $1,000 in tax debt and still qualify. DMV debts (parking tickets, tolls, vehicle fines) are capped separately at $100. If you're blocked, resolve the debt or enter into an installment agreement before proceeding.

Step 4: Compile Your Contractor-Specific Documents

What you need depends on your licensing category:

General Contractor (Classes A, B, C, G, and H):

• Certificate of Insurance (COI) showing Commercial General Liability (CGL) coverage matching your class — from $500,000 per occurrence (Class H) up to $2,500,000 (Class A)
• The COI must list "Department of Licensing and Consumer Protection" as the certificate holder, at the exact address: 1100 4th Street, SW, Washington, DC 20024
• Insurance carrier must have an A.M. Best rating of B+ or higher
• If performing residential work, submit the required sample contracts and designate at least one Home Improvement Salesperson (HIS)

Home Improvement Contractor (HIC):

• Certificate of Insurance showing at least $50,000 for bodily injury or death of one person in a single accident, $100,000 in the aggregate for multiple persons, and $10,000 for property damage
• $25,000 surety bond (must remain active for the full two-year license period)
• Police criminal history report — Form PD-70 from the DC Metropolitan Police Department for DC residents ($7), or an equivalent certified report from your home jurisdiction for non-residents, dated within 30 days of your BBL submission
• Two blank copies of your pre-printed residential contract in triplicate format, including the mandatory Buyer's Right to Cancel clause
• At least one designated Home Improvement Salesperson (HIS) — sole proprietors can designate themselves but must apply for a separate HIS license ($99 biennial fee)

Step 5: Submit Your BBL Application

With everything above in hand, apply through the BOSS portal at boss.dc.gov. Upload your zoning clearance, OTR registration, insurance certificates, and any contractor-specific documents.

Fees under the BEST Act:

• 6-month license: $49 (GC only; not available for HICs)
• 2-year license: $99
• 4-year license: $198
• Sole-proprietor exemption: $0 if annual revenue is under $10,000 (you still need the license itself)

Processing typically takes one to two weeks if no documents are flagged. Once approved, the printable license is available in your BOSS dashboard.

Step 6: Keep It Current

Your BBL expires at the end of the issuance month, six months, two, or four years from the date it was issued, depending on the term. Renewal opens 90 days before expiration through BOSS. Late penalties under the BEST Act are capped: $75 for the first 30 days, $150 up to six months, and a maximum of $350.
