Collin County cities cap single-family lot coverage at 40-50% of total lot area including house, garage, and accessory structures. Impervious surface limits run 50-70% depending on zoning district.
Plano Zoning SF-7 limits building coverage to 40%, Frisco SF-9 caps at 45%, McKinney SF-5 allows 50%. Larger lots (SF-1A, 1-acre) in Fairview and Lucas typically allow 20-25% coverage. Impervious surface (driveways, patios, pools) is typically capped at 60-70% in standard SF zones and 35-45% in estate zones. Pervious pavers and grass grids often count as 50% impervious. Collin County has no countywide coverage rule in unincorporated areas, but deed restrictions commonly enforce 35-40% coverage caps.
Coverage exceedance: city denies permit until plan revised. Built-out violations require variance petition or removal. Drainage impact from excess impervious may trigger stormwater fines.
