Artificial turf is allowed on Kent single-family lots but usually counts as impervious surface for stormwater. Large installs may require drainage review under Title 7 and Critical Areas rules.
Kent does not ban artificial turf on residential property, and it is often installed in backyards and sport courts. The key regulatory issue is stormwater. Kent City Code Title 7 and the Washington Stormwater Management Manual treat permeable surfaces based on their actual infiltration rate. Most synthetic turf on a compacted base performs close to pavement, so the city may count it as impervious surface when evaluating drainage, lot coverage, and runoff controls. Installations over 2,000 square feet or within Critical Area buffers can trigger a stormwater review or permit. Homeowners should plan for perimeter drains, a permeable base where feasible, and ensure runoff is not directed onto neighbors. The Green Kent ethic favors native plantings over synthetic turf for habitat and urban heat reasons, but the city does not prohibit turf on residential lots.
