Full Breakdown
The Building Safety Division, housed in the Development Services Department under the Building Safety Director (§ 4-1-3(A)), reviews every application. Section 4-1-4(B)(1) exempts specific minor work from a building permit: one-story detached accessory structures like sheds or playhouses up to 200 square feet on single-family lots, fences up to 6 feet on single-residence-zoned property, retaining walls up to 4 feet, sidewalks and driveways up to 30 inches above grade, water tanks up to 5,000 gallons on grade, and prefabricated above-ground pools no deeper than 18 inches holding up to 5,000 gallons, provided none of these sit on Desert Uplands-regulated property, in a Historic Preservation Overlay District, or on a designated historic landmark site.
An application must identify the work, legally describe the property, state the construction valuation, be signed by the owner or agent, and include proof of a valid Arizona contractor's license and bond (§ 4-1-4(H)). An application is deemed abandoned 180 days after filing unless pursued in good faith or the Director grants a written extension of up to 90 days (§ 4-1-4(H)(5)). A rejected application, or any other order of the Building Safety Director, can be appealed in writing to the Building Board of Appeals within 30 days under Mesa City Code, Chapter 2-11 (§ 4-1-2(Q)).
Violations & Fines
Starting regulated work without the required permit triggers an unauthorized construction fee under § 4-1-8(T), charged in addition to the normal permit fee whether or not a permit is later issued. Under the Penalty Clause at § 4-1-9(E), anyone who violates the permit chapter is guilty of a Class One misdemeanor, punishable by a fine up to $2,500, up to six months in the city jail, or both, with each day the violation continues counted as a separate offense. The Building Safety Director may also issue a written stop-work order requiring immediate cessation of the work (§ 4-1-3(L)).
