Full Breakdown

The construction noise rule is 20 DCMR section 2803.2: no noise from construction, excluding minor home repairs, is permitted within a residential, special purpose or waterfront zone on any Sunday or legal holiday, or after 7 p.m. and before 7 a.m. on any weekday. The Sunday and holiday prohibition is outright, not an hours window, a point widely misreported. Exemptions cover portable power tools used for minor home improvements, public utilities, the transit authority and their subcontractors, though decibel caps still apply to the exempt work. Projects needing to work outside the window apply to the Department of Buildings for an after-hours permit.

Violations & Fines

Construction noise outside the permitted window, or on a Sunday or legal holiday without an after-hours permit, violates 20 DCMR 2803 and is enforced through the District's environmental noise programme.
