Adopted code

City of Glendale - Development Services Department, Building Safety

The City of Glendale, Arizona (Maricopa County) issues building permits through its Development Services Department at 5754 W. Glenn Drive. The City's December 10, 2025 implementation memo says the City "adopted the 2024 International Building Codes, Fire Codes and amendments" on December 9, 2025, effective January 9, 2026. Arizona has no statewide building code, so Glendale's own adoption controls. This listing covers the office's contact details, the adopted code edition and transition dates, the wind and ice-barrier design values in the City's Table R301.2 amendment, and the state licensing and tax rules that apply to a roofer working in Glendale. The City's reroof permit rule was not located, so this record makes no permit-required statement.

Registration details
  • license: STATE LAYER, applies in Glendale 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." 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.
Adopted code
The City's Development Services memo dated December 10, 2025 states: "On December 9, 2025, the City of Glendale adopted the 2024 International Building Codes, Fire Codes and amendments. The effective date of the 2024 Building Codes and amendments is January 9, 2026." It adds that the 2018 Building Codes remain in effect for plans submitted through July 9, 2026 only in listed grace-period situations, and that "All plans submitted after July 9, 2026, must comply with the 2024 Building Codes, Fire Code and amendments." The adopting ordinance amends Glendale City Code Chapter 9, Articles II and III. The ordinance's amendments other than the Table R301.2 values quoted under wind design were not read for this record, so it gives no answer that depends on them.
Ice & water shield
Not required — The ordinance's amended Table R301.2(1) lists "No" in the ice barrier underlayment required column. About ice & water barrier
Wind design criteria
The ordinance's amended Table R301.2(1) lists the wind design as "115 mph ultimate" and "89 mph ASD," seismic design category "B," weathering "Negligible," termite "Moderate to Heavy," winter design temperature "32F" and mean annual temperature "72.6F."
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 6.30% for Maricopa County (the 5.6% state rate plus the county rate) and at 2.90% for the City of Glendale (city code GE), a combined 9.20%. 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 9.20% 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."
