DC is one of the most active commercial construction markets in the country — office conversions, federal building rehabs, embassy and institutional work, and tight Northwest and Capitol Hill infill projects. DC construction law has its own rules: mechanic's liens follow a unique notice and timing structure, the DC Construction Codes Coordinating Board sets specifications above the IBC baseline, and prevailing-wage and Davis-Bacon issues are constant.
DC construction disputes cluster around four common situations. Payment — a general contractor isn't paying subs, a subcontractor isn't getting paid, a federally funded project is hung up on a Miller Act bond, or a private project is heading toward DC's mechanic's lien process. Defect and delay — an owner is alleging defective work, a contractor is claiming compensable delay, weather or differing-site-conditions claims are in dispute. Bidding — protests of DC government or federal procurement awards, bid-mistake withdrawals, prequalification disputes. Permitting and zoning — DCRA Construction Code disputes, BZA appeals, Historic Preservation Office holds in DC's many historic districts.
DC's mechanic's lien procedure under DC Code § 40-301.01 et seq. is unforgiving. A general contractor must file the lien within 90 days of completion of the project; subcontractors and suppliers must file within 90 days of last furnishing labor or materials. The lien must be perfected by suit within 180 days. Miss either deadline and the lien is gone. Federally funded projects use the Miller Act (40 U.S.C. § 3131 et seq.) payment bond process instead, with its own 90-day notice and one-year limitation rules. A DC construction lawyer should be involved before deadlines slip, not after.
DC also layers in prevailing-wage requirements. The DC Living Wage Act and DC Davis-Bacon parallel statute apply to most DC government-funded projects; federal Davis-Bacon applies to federal-funded projects above $2,000. Misclassification of workers or wage shortfalls trigger DOES (DC Department of Employment Services) audits and federal DOL Wage and Hour Division actions. DC government contractors operating without familiarity with these wage statutes often run into back-pay liability and debarment exposure.

Construction-defect and delay litigation in DC typically runs $45,000-$250,000+ in legal fees on the defense side and $75,000-$500,000+ on a complex plaintiff-side delay/disruption claim with expert testimony. Many DC construction lawyers work on a hybrid hourly-plus-contingency basis for clear-liability payment claims.
A DC mechanic's lien filing requires action within 90 days of completion (general) or last labor/material (sub/supplier). Perfection requires suit within 180 days. A Miller Act payment-bond claim on a federal project requires 90 days' notice and suit within one year of last labor or materials.
Custom DC construction contracts (AIA-form modifications, design-build agreements, GMP contracts) take 2-5 weeks from first call to executed version. Project disputes that don't go to suit (mediation, payment-application disputes resolved through letter exchanges and partial payments) often resolve in 2-6 months.
DC Superior Court Civil Division typically reaches trial in 14-22 months on commercial construction cases. AAA construction arbitrations move faster — 9-15 months from filing to award — and most DC construction contracts default to AAA construction rules.
