Oklahoma City §59-4150 limits R-1 building coverage to 40 percent of lot. R-2/R-3 allow 50-60 percent. Stormwater management required for impervious surfaces over threshold.
Oklahoma City Municipal Code §59-4150 caps maximum lot coverage by buildings at 40 percent for R-1 single-family, 50 percent for R-2, and 60 percent for R-3. Impervious surface coverage (buildings + driveways + patios + pool deck) is limited to 60 percent in R-1 zones, with excess requiring a stormwater management plan per OKC Drainage Ordinance §27-200. Accessory structures count toward coverage. Permeable pavers may count at 50 percent of their surface area if certified by manufacturer. Edmond Code §22-30 uses 40 percent building coverage for R-1. Midwest City and Del City follow similar limits. Oklahoma is a runoff-sensitive area given intense spring thunderstorms (2-4 inch hourly rates possible) — OKC enforces MS4 stormwater requirements under EPA NPDES permit. Exceeding lot coverage without variance may trigger required demolition. Board of Adjustment variances require hardship demonstration. Some newer PUDs allow higher coverage with green infrastructure requirements.
Exceeding lot coverage: correction required + $250 to $1,000 (OKC §59-9999). May need to remove impervious surface. Stormwater violations: $500 to $2,500 under §27-200.
