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

Adopted code

City of Casa Grande - Planning & Development Department, Building Division

No, Casa Grande, AZ does not require a permit for like-for-like roof replacement (City of Casa Grande - Planning & Development Department, Building Division). Section 105.2 (Work exempt from permit), Building, item 16 of the City's 2019 Administrative Code lists: "The replacement of asphalt shingle roofing materials on one- and two-family dwellings and their accessory structures. The replacement roofing must be the same material as what was removed. (Three tab, architectural, or mineral roll) Replacement with other roofing materials or any structural repairs shall require permitting." A permit is therefore not required for a same-material asphalt shingle replacement on those buildings and is required for other roofing materials or structural repairs.

Registration details
  • license: STATE LAYER, applies in Casa Grande as everywhere in Arizona. Contractors are licensed by the Arizona Registrar of Contractors under A.R.S. Title 32, Chapter 10 (32-1101 et seq.). A.R.S. 32-1121(A)(14) exempts an unlicensed person only for one project whose aggregate contract price, including labor and materials, is "less than $1,000" and whose work is "of a casual or minor nature," and says the exemption "does not apply: (a) In any case in which the performance of the work requires a local building permit." An unlicensed person who advertises must include the words "not a licensed contractor." Owner-occupants doing their own work on a structure intended solely for their own occupancy are separately exempt under 32-1121(A)(5). The specific roofing classification codes and the Registrar's own licensing page were not read for this record.
Permit process note
Section 105.2 (Work exempt from permit), Building, item 16 of the City's 2019 Administrative Code lists: "The replacement of asphalt shingle roofing materials on one- and two-family dwellings and their accessory structures. The replacement roofing must be the same material as what was removed. (Three tab, architectural, or mineral roll) Replacement with other roofing materials or any structural repairs shall require permitting." A permit is therefore not required for a same-material asphalt shingle replacement on those buildings and is required for other roofing materials or structural repairs.
Adopted code
The City's Building and Technical Administrative Code, Chapter 15.04, 2019 Edition, carries the line "Effective: July 1, 2019" and applies the International Residential Code "as adopted and amended by the Mayor and Council." The City's Regulatory Bill of Rights directory lists "2018 ICC Amendments" as the construction code amendments available for review. A Building Division notice dated 9/25/2026 says the City "is currently proceeding with the adoption of the 2024 ICC I-Codes (IBC, IFC, IEBC, IRC, IMC, IFGC, IPC, IPMC, ISPSC, and IECC) and the 2023 NEC," with public meetings beginning October 7, 2026. The 2018 amendment text itself was not read, so this record states no local amendment beyond the permit exemption quoted below.
Repair permit threshold
The threshold is a quantity of decking, not a dollar amount. Under the same exemption (Section 105.2, Building, item 16): "Up to three sheets of structural sheathing or 96 square feet of other wood decking material may be replaced at this time without permits."
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 Casa Grande (city code CG), 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."
