Collierville, TN Building Setbacks & Zoning: Setback Rules (2026)

Setbacks in the residential districts of the Town of Collierville, Tennessee, come from the table in § 151.027(A), which lists front, rear and side yards for each district. In R-1 (Low Density, single-family detached) the front setback is 40 ft., the rear is 30 ft., and the side is 25 ft. total with neither side less than 10 ft. In R-2 (Medium Density) the front is 30 ft., the rear is 30 ft., and the side is 20 ft. total with neither side less than 7.5 ft. Larger lots carry bigger yards: the Forest Agriculture Residential district requires 100 ft. in front and 75 ft. in the rear, and R-L1 requires 50 ft. in front, 40 ft. in the rear and 25 ft. on the side. At the dense end, R-3 requires 30 ft. in front and in the rear with 7.5 ft. on each side for single-family homes and 10 ft. on each side for duplexes, and R-4 requires 30 ft. front, 30 ft. rear and 10 ft. side.

The table footnotes change the raw numbers. Note [1] puts a front yard on each street for corner lots and double frontage lots. Note [3] lets the front yard for dwellings be reduced under § 151.005(A): where the average depth of existing front yards on developed lots within 300 feet on each side along the same block face is less than the minimum, the new lot can match that average, but in residential districts the front yard can never be less than 25 feet. Note [5] allows appurtenances to encroach under § 151.005(E): gutters, eaves and cornices can project up to 24 inches but stay no closer than 36 inches to a property line, bay windows can project up to 42 inches, and porches can project up to 72 inches, with front porches no closer than 20 feet to the back of the curb.

An owner of a substandard lot of record who cannot meet the yard rules can apply to the Board of Zoning Appeals for a variance under § 151.309. Mobile home parks add a 20 foot wide buffer area on top of the yard requirements, under note [4]. Nonresidential districts have their own setback columns in § 151.027(B) and (C), including 20 ft. side yards adjoining residential property in the NC and GC districts.
