Do you need a permit to replace a roof in Unincorporated Yavapai County, AZ?

Adopted code

Yavapai County Development Services - Building Safety Unit

No, Unincorporated Yavapai County, AZ does not require a permit for like-for-like roof replacement (Yavapai County Development Services - Building Safety Unit). Ordinance 2025-4 amends IRC Section R105.2 (Work exempt from a permit). Its item 15 exempts "Re-roofing (like for like, maximum one hundred (100) square feet sheathing replacement and no more than two (2) layers) on residential properties." The ordinance states "These exemptions do not apply to commercial projects" and that the exemption applies "ONLY to Building Safety. Other Yavapai County regulatory agencies may have permit requirements for these exemptions." A residential reroof that changes the roofing material, replaces more than 100 square feet of sheathing, or leaves more than two layers is therefore outside the exemption as written; the Unit's treatment of those cases beyond this text was not read. The Unit's page also posts a Residential Roof Sheathing Form and a Residential Roof Final Form.

Registration details
  • license: STATE LAYER, applies in unincorporated Yavapai County 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
Ordinance 2025-4 amends IRC Section R105.2 (Work exempt from a permit). Its item 15 exempts "Re-roofing (like for like, maximum one hundred (100) square feet sheathing replacement and no more than two (2) layers) on residential properties." The ordinance states "These exemptions do not apply to commercial projects" and that the exemption applies "ONLY to Building Safety. Other Yavapai County regulatory agencies may have permit requirements for these exemptions." A residential reroof that changes the roofing material, replaces more than 100 square feet of sheathing, or leaves more than two layers is therefore outside the exemption as written; the Unit's treatment of those cases beyond this text was not read. The Unit's page also posts a Residential Roof Sheathing Form and a Residential Roof Final Form.
Adopted code
The County's code package is titled "Ordinances Adopting the 2024 International Building Codes and the 2023 National Electric Code, 2012 International Energy Conservation Code, and Yavapai County Grading Ordinance for the Unincorporated Areas of Yavapai County," marked "Effective January 1, 2026." Its table of contents lists Ordinance 2025-3 (International Building Code, 2024 Edition), Ordinance 2025-4 (International Residential One- & Two-Family Dwelling Code, 2024 Edition), Ordinance 2025-5 (Plumbing), 2025-6 (Mechanical), 2025-7 (Fuel Gas), 2025-8 (National Electrical Code, 2023 Edition), 2025-9 (Property Maintenance), 2025-10 (Grading), 2025-11 (Existing Building) and 2025-12 (Swimming Pool and Spa). The County's Ordinances and Regulations page marks the 2024 amendments "Effective 1/1/2026."
Repair permit threshold
The threshold is stated in the exemption itself, in Ordinance 2025-4, R105.2 item 15: re-roofing exempt from a building permit is "like for like, maximum one hundred (100) square feet sheathing replacement and no more than two (2) layers" on residential properties. The same list exempts item 9, "Remodels (non-structural and no increase in square footage or plumbing, electrical, and mechanical) on residential properties," and item 17, "New doors and windows (replacement, if same size, type, and function)." The ordinance gives no dollar figure for roofing.
Wind design criteria
Ordinance 2025-4 replaces IRC Table R301.2 with a County table that prints: Ground snow load "20 - 70*" (the asterisk refers to a footnote for elevations over 7,000 feet); Wind design speed 105 mph, Exposure C; Topographic effects NO; Special wind region NO; Windborne debris zone NO; Seismic Design Category C; Weathering "Below 3500: negligible, Above 3500: moderate"; Frost line depth 12 inches below 4,500 feet, 18 inches at or above 4,500 feet, 24 inches at or above 6,500 feet. Footnote d to the table says the jurisdiction fills the wind column "with the wind speed from the ultimate design wind speeds map [Figure R301.2(2)]." The ground snow load varies with elevation, so a site above 3,500 feet needs the site's own value from the County's table and footnote.
Deck & sheathing requirements
Ordinance 2025-4 replaces the sheathing requirements in several IRC Chapter 9 sections. R905.3.1: "Concrete and clay tile shall be installed over wood structural panels or solid lumber sheathing," with the exception "Spaced lumber sheathing is permitted for attached covered patios." R905.4.1 (metal roof shingles), R905.7.1 (wood shingles), R905.8.1 (wood shakes), R905.15.1 (BIPV shingles) and R905.16.1 (BIPV roof panels) each say the covering "shall be installed over wood structural panels or solid lumber sheathing." R905.10.1 says the same for metal roof panels, with the same attached-patio exception for spaced lumber sheathing and the requirement that "Installation must comply with manufacturer's installation requirements." The ordinance does not amend the asphalt shingle sheathing section, so the base 2024 IRC applies there.
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 6.35% for Yavapai County (the 5.6% state rate plus the county rate). That table carries city rates only for incorporated cities and towns, so this record, which covers unincorporated territory, adds no city rate. 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 6.35% 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."

Arizona has no statewide building code, so the County's own adoption controls. This listing covers the office's contact details, the adopted code, the re-roof exemption, the design criteria and roof-sheathing amendments, and the state licensing and tax rules that apply to a roofer working in unincorporated Yavapai County.
