City of Winslow - Community Development, Building Permits

The City of Winslow, Arizona (Navajo County) takes building permit applications through its Community Development page at City Hall, 102 E. Third Street. Winslow City Code Title 15, Chapter 15.04 adopts the 2018 International Building Code and 2018 International Residential Code with local amendments, including a Table R301.2(1) amendment that sets a 30 psf ground snow load, a 115 mph wind speed in a special wind region, and an ice barrier that is "Recommended but not required." Arizona has no statewide building code, so the City's own adoption controls. This listing covers the office's contact details, the adopted code edition and design values, and the state licensing and tax rules that apply to a roofer working in Winslow.

Registration details
  • license: STATE LAYER, applies in Winslow 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." The specific roofing classification codes and the Registrar's own licensing page were not read for this record.
Adopted code
Winslow City Code Title 15, Chapter 15.04 says: "The 2018 International Building Code, including Appendix K; 2018 International Residential Code, including Appendix Q and Appendix K; 2018 International Mechanical Code; 2018 International Plumbing Code; 2018 International Fuel Gas Code; 2017 National Electrical Code; 2018 International Property Maintenance Code; and the 2018 International Existing Building Code are adopted by the City of Winslow." The chapter amends the IBC and IRC administrative sections. Its amended R105.2 lists the work exempt from permit (sheds, retaining walls, water tanks, sidewalks and driveways, finish work, shallow pools, playground equipment, awnings) and does not mention roofing. The City's Permit FAQs page returned no readable text, so this record gives no answer on reroofing permit practice.
Ice & water shield
Not required — Winslow's amended IRC Table R301.2(1) reads "Ice Barrier: Recommended but not required." About ice & water barrier
Wind design criteria
Winslow's amended IRC Table R301.2(1) reads: "Ground Snow Load: 30 psf," "Wind Speed: 115 (Special Wind Region)," "Wind Exposure Category: C," "Weathering: Moderate," "Frost Depth: 18 inches," "Termite: Moderate to Heavy" and "Mean Annual Temp: 54.4."
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 6.43% for Navajo County (the 5.6% state rate plus the county rate) and at 3.00% for the City of Winslow (city code WS), a combined 9.43%. 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 9.43% 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."
