Summary
Queen Creek's adopted Building Code exempts a retaining wall from a building permit only if it stands 4 feet or less from the bottom of its footing to the top and does not hold back a surcharge or impound hazardous liquids. Anything taller, or carrying extra load, needs Building Safety review. The Zoning Ordinance treats retaining walls as legally distinct from fences.
4. Retaining walls which are not over 4 feet (1219 mm) in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge or impounding Class I, II or III-A liquids.
Full Breakdown
Town Code Section 7-1-4-2-1, which adopts the International Building Code's list of work exempt from permit, sets the Town's retaining wall threshold: a retaining wall that is not over 4 feet high, measured from the bottom of the footing to the top of the wall, does not need a building permit, unless it supports a surcharge or impounds Class I, II or III-A liquids. Cross that height, add a surcharge load such as a driveway or structure behind it, or use it to hold back flammable or combustible liquids, and the wall needs a permit and Building Safety plan review before construction starts, the same way any other structural element under the adopted Building Code does.
The Zoning Ordinance keeps retaining walls out of its fence rules entirely. 2, which limits a front-yard fence to 36 inches and a side or rear fence to 6 to 8 feet, does not by its terms cap a retaining wall's height. 3 says the combined height and location requirements can be modified through a subdivision, planned area development, special use or conditional use approval, and directs the applicant back to the retaining wall definition to work out how the structure is measured.
Violations & Fines
Building a retaining wall over 4 feet, or one that carries a surcharge or impounds hazardous liquids, without first pulling a permit is unpermitted work under the Town's adopted Building Code (Town Code Chapter 7). Building Safety can red-tag the site and issue a stop-work order until the wall is permitted and inspected, and the adopted Building Code treats unpermitted construction as a violation subject to correction before any further work or final approval proceeds.
