Collierville, TN Building Setbacks & Zoning: Lot Coverage Limits (2026)

The Collierville Code of Ordinances sets a numeric lot coverage cap in its two industrial districts. In § 151.027(C), the RI Restrictive Industrial district and the GI General Industrial district each show a Maximum Lot Coverage of 50% of total lot area. The residential table in § 151.027(A) has no lot coverage column; it shapes the building envelope through minimum lot size, minimum lot width, maximum height and setbacks. The commercial and office table in § 151.027(B) uses a Maximum Floor Area Ratio column instead.

Section 151.003 defines LOT COVERAGE as that portion of a lot that is covered by a building or any part of a building, so the definition counts building area. Section 151.006(A)(2)(c) adds that no building or other structure can be erected or altered to occupy a greater percentage of lot area, where applicable.

The same industrial table carries the dimensional rules that sit alongside the cap. RI shows a 60 ft. maximum height, a front setback of 40 ft., a rear setback of 30 ft. adjoining residential and otherwise 25 ft., and a 25 ft. side setback. GI shows a 2 acre area, a 60 ft. maximum height, a front setback of 40 ft., a rear setback of 50 ft. adjoining residential and otherwise 25 ft., and a side setback of 40 ft. adjoining residential and otherwise 25 ft. In RI and GI the Planning Commission, during site plan review, can allow a greater building height provided that no fire hazard is created in the opinion of the Fire Marshal.

Accessory structures tie back to coverage in § 151.025. In industrial districts, the total maximum area of all accessory structures shall not exceed 20% of the maximum lot coverage permitted within the zoning district. On residential lots less than two acres in size, the combined gross floor area of all accessory structures is capped at 30% of the total gross floor area of the principal building, and the Development Director or designee must find the structure consistent with the character of existing development nearby before a building permit issues.
