Wylie, TX Building Setbacks & Zoning: Setback Rules (2026)

Appendix B, Article 3 sets yard setbacks district by district, each in its own numbered Figure. In the SF-10/24 District (Figure 3-4, the city's smallest standard single-family lot at 10,000 square feet), the front yard is 25 feet, the side yard is 10 feet, a side yard on a corner lot is 25 feet, a side yard next to an allowable nonresidential use is 30 feet, the rear yard is 25 feet, and a double-front lot's rear yard rises to 45 feet. Larger-lot districts scale up in step: SF-20/26 (Figure 3-3) sets a 30-foot front and rear yard, SF-Estate (Figure 3-2) sets 50-foot front and rear yards on its 1-acre minimum lots, and AG/30 (Figure 3-1) also requires 50 feet front and rear on its 2-acre minimum lots.

Section 3.2.B.4.b carves out one exception for SF-10/24: a non-enclosed attached patio cover is exempt from the standard rear setback and may extend to within 10 feet of the rear property line, as long as the lot's overall coverage cap of 45 percent is not exceeded. Detached accessory buildings follow a different, citywide setback table in Section 2.5.C.2.c rather than the main-structure figures, so a shed or detached garage is not held to the 25-foot rear line that applies to the house itself. The Building Official checks these distances against the recorded plat and the submitted building plans before issuing a permit, and setback lines shown on an approved plat can be more restrictive than the ordinance minimum where a builder or the plat itself established a stricter line.
