Sandy, UT Environmental Rules: Defensible Space (2026)

Section 18-1-3 folds the City's defensible-space standard directly into the ignition-resistant construction rules adopted from the 2006 International Wildland-Urban Interface Code. 7, covering exterior wall coverings, under-floor and appendage protection, and exterior glazing, actually apply: only on the side of the structure that the Fire Code Official identifies as the exposure side, and only when the defensible space around that side measures less than 50 feet as defined in IWUIC § 603. A homeowner who maintains at least 50 feet of cleared, managed defensible space on the exposed side is not required to meet those three subsections on that side of the building.

7, out of the Class 2 ignition-resistant construction standard entirely, regardless of defensible space distance. 1 defensible-space carve-out is even measured. Sandy Fire Department and the Building Division jointly enforce compliance, checking defensible space distance and Class I or Class 2 material specifications together during plan review and pre-occupancy inspection for any home in a mapped Wildland-Urban Interface Area near the foothills or Little Cottonwood Canyon.
