Do you need a permit to replace a roof in Maricopa, AZ?

Adopted code

City of Maricopa - Development Services Department, Building Safety

No, Maricopa, AZ does not require a permit for like-for-like roof replacement (City of Maricopa - Development Services Department, Building Safety). Maricopa City Code 15.05.050(B)(4) amends IRC R105.2 (work exempt from permit) by adding item 12: "Replacement of a roof cover where the replacement roof covering classification is equal to or greater than the existing roof covering classification and does not increase the loads upon the structural frame." A permit is therefore not required for a like-or-better roof cover replacement that adds no structural load. The chapter's building code amendment (15.05.040(B)(2)) adds a similar item for commercial buildings: "Roof covering provided no structural alterations would be required by this code due to additional loads." Work outside these exemptions, such as structural repair, was not found addressed in the sections read, so it is not stated here.

Sales & use tax
Roofing is taxed in Arizona as Prime Contracting (business code 015) under the Transaction Privilege Tax, not as a retail sale. The Arizona Department of Revenue Transaction Privilege and Other Tax Rate Tables effective October 1, 2026 list Contracting - Prime at 6.70% for Pinal County and at 4.00% for the City of Maricopa (city code MP), a combined 10.70%. A.R.S. 42-5075(B) sets the tax base at "sixty-five percent of the gross proceeds of sales or gross income derived from the business," so the combined rate applies to 65% of contract income. The same statute excludes from the classification "any work or operation performed by a person that is not required to be licensed by the registrar of contractors pursuant to section 32-1121."
