Keller Zoning Ordinance caps building lot coverage, generally 40 to 50 percent in single-family districts. Total impervious coverage is limited to protect drainage and recharge, especially in large-lot SF-36 areas.
Lot coverage in Keller is measured as the percentage of the lot covered by the principal building footprint and, separately, the total impervious surface including driveways, patios, pools, and accessory structures. Base district maximums vary: larger-lot districts like SF-36 typically allow a lower building coverage, around 30 to 40 percent, to preserve open character, while tighter districts like SF-8.4 and SF-10 often allow up to 50 percent building coverage. Total impervious coverage including hardscape is typically capped around 60 to 70 percent depending on district and stormwater overlay. Accessory buildings count toward total coverage and must meet their own setback and size limits. Pool decks, patios, and extensive paver installations require a building permit with site plan review and can push a lot over its impervious limit, requiring drainage features such as dry wells, rain gardens, or permeable pavers. The Zoning Ordinance and Engineering Design Standards coordinate lot coverage with detention requirements, particularly for lots adjacent to Big Bear Creek and other drainage corridors. Homeowners planning significant additions, pools, or hardscape should pull the plat and confirm platted easements and coverage conditions. Variances to lot coverage require Zoning Board of Adjustment review. HOA covenants in Keller subdivisions sometimes impose stricter coverage or landscape requirements than the base zoning.
Zoning violations up to $500 per day. Overbuilt lots may require removal of excess hardscape or installation of on-site detention at owner expense.
