Wylie, TX Building Safety: Green Building Code (2026)

Section 3.4 sets a two-tier system for new residential development in Wylie: every project must fully satisfy the Base Standard for each design element, and separately select a minimum number of Desirable Design Attributes to reach the level required by Figure 3-9's category totals; the Architectural category alone requires 5 of its 9 listed desirables. Under the Conservation/Sustainability line of Figure 3-9(C), the mandatory Base Standard is only that each residential dwelling unit comply with the Energy component of the adopted Building Code, the same energy code baseline every house in the city must meet regardless of design choices.

The Desirable option on the same line, repeated in the detailed text at Section 3.4.F.15, lets a builder claim credit toward the 5-of-9 architectural quota if the unit is certified by United States Green Building Council (USBG) or Leadership in Energy and Environmental Design (LEED). Nothing in Appendix B requires that certification; a developer can hit the 5-of-9 threshold entirely through the other eight desirables, such as upgraded porches, chimneys or garage size, without ever pursuing LEED or USGBC review. There is no separate green building chapter, no local energy-code overlay beyond the Building Code's energy component, and no fee schedule or inspection track tied to third-party green certification anywhere in the Code of Ordinances or Appendix A Fee Schedule. Planning staff verify which desirables a project selected at plat and site-plan review, not through a dedicated green-building permit.
