Lawton, OK Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 18-5-3-526 measures coverage as the combined footprint of the main house and every accessory building, capping it at 45 percent of the lot in the R-1 Single-Family Dwelling District; townhouses are carved out to the separate calculation in Section 18-4-1-418. The R-2 Two-Family Dwelling District carries the identical 45 percent cap under Section 18-5-4-538, so a duplex lot or a single-family lot with a garage apartment faces the same footprint ceiling as a plain single-family lot. Coverage tightens sharply in the lower-density A-2 Suburban District, where Section 18-5-2-515 limits it to 25 percent on interior lots and 30 percent on corner lots, with accessory buildings alone capped at 20 percent of the rear yard.

It loosens just as sharply on the industrial side: the I-1 Restricted Manufacturing and Warehouse District allows 85 percent lot coverage under Section 18-6-14-652, and the I-2 Industrial Park District allows 40 percent under Section 18-6-15-662. The 45 percent R-1 figure has carried forward unchanged through the 2002-34 and 12-07 amendments that otherwise rewrote the surrounding sections of Division 18-5-3.
