Washington, DC Landscaping Rules: Artificial Turf (2026)

Artificial turf in DC is not outright prohibited for residential use, but several regulatory frameworks effectively limit where and how it is installed. The Stormwater Management Regulations (DCMR 21-5) treat artificial turf as impervious surface (equivalent to concrete) for stormwater calculations, meaning installations over 400 square feet may trigger stormwater retention requirements. The Tree Protection Act (DC Code 8-651 and DCMR 20-24) prohibits disturbance within the Critical Root Zone of Special Trees (44+ inch circumference) without an arborist review, and turf installation that compacts soil or severs roots within the CRZ is typically denied. Historic Preservation Review Board guidance in Georgetown, Capitol Hill, and other historic districts generally prohibits street-visible artificial turf as inconsistent with period landscaping. DOEE has raised environmental concerns about PFAS content and microplastic shedding from synthetic turf, leading the DC Council to debate limits on public-field installations. Residential front-yard turf is uncommon and may generate HOA or neighbor complaints. No permit is required for residential turf replacement on an existing lawn area, but grading or drainage changes require a DOB permit.
