Artificial turf is allowed in Redmond residential yards with no specific permit, but installations over 500 square feet may affect stormwater calculations and turf is discouraged in critical area buffers.
Redmond does not prohibit artificial turf for residential yards and synthetic lawns are increasingly common for low-maintenance landscaping. However several city regulations apply. Large turf installations that replace pervious lawn with an effectively impervious surface can trigger stormwater review under RMC 15.24 when combined with other hard surfaces exceed thresholds (typically 2,000 square feet new or replaced impervious surface). Artificial turf is not allowed as a substitute for native vegetation in critical area buffers, mitigation plantings, or shoreline setbacks because it provides no habitat or infiltration value. Infill crumb rubber has come under Ecology scrutiny for stormwater contamination; organic infills are preferred. HOA covenants may restrict synthetic lawns in some Redmond neighborhoods, so check your CCRs before installation. Installations over a geotextile with crushed rock base require proper drainage to avoid basement flooding and runoff onto neighbors.
