Full Breakdown
Maricopa adopts the 2024 International Residential Code and amends Section R105.2's list of work exempt from permit. Item 1, added by the city, exempts one-story detached accessory structures, sheds, in practice, from a building permit if the floor area does not exceed 200 square feet and the wall plate height at its highest point does not exceed 8 feet, with no mechanical, electrical or plumbing components. Cross the size or height limit, or add any MEP work, and the shed needs a full building permit reviewed under the amended IRC through the city's Development Services Department.

Building without a required permit is a Class 1 misdemeanor under MCC 15.05.210, and each missing permit, inspection or approval counts as a separate violation; the city can instead pursue a civil penalty up to $1,000 for an individual or $10,000 for an enterprise per offense.
