Adopted code

City of Kingman - Development Services, Building Division

The City of Kingman, Arizona (Mohave County) issues building permits through the Building Division of its Development Services Department. The City's Code Information & Design Criteria page lists the 2018 International Building and Residential Codes and the 2017 National Electrical Code as the current adopted codes. Arizona has no statewide building code, so Kingman's own adoption controls. This listing covers the office's contact details, the adopted code edition, the reroofing rules in the 2018 IRC that the City's published amendments leave unchanged, and the state licensing and tax rules that apply to a roofer working in Kingman. The City's own reroof permit rule was not found on its pages and is not stated here.

Registration details
  • license: STATE LAYER, applies in Kingman 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 Code Information & Design Criteria page lists under Current Adopted Codes the "2018 International Building Code (IBC)," "2018 International Residential Code (IRC)," "2018 International Existing Building Code (IEBC)" and "2017 National Electrical Code (NEC)," along with the 2018 Fire, Plumbing, Mechanical, Fuel Gas, Energy Conservation, Property Maintenance and Swimming Pool and Spa codes. The City's Code Amendments page lists local amendments to the IRC, including adopted Appendices A, B, C, H, J, O, Q, R and S, a Chapter 3 change to Table R301.2(1), and changes to Chapters 4, 11 and 39. It lists no amendment to IRC Chapter 9, Roof Assemblies. The text of the Municipal Code adopting ordinance was not read for this record.
Drip edge
Required — The 2018 International Residential Code, Section R905.2.8.5, says "A drip edge shall be provided at eaves and rake edges of shingle roofs" and "Underlayment shall be installed over the drip edge along eaves and under the drip edge along rake edges." The City's published IRC amendments list no change to Chapter 9. The City's own roofing-specific guidance was not found. About drip edge
Roof layer limit / recover
The 2018 International Residential Code, Section R908.3, says "Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck." Section R908.3.1.1 says a roof recover (a new covering over the old) "shall not be permitted" where "the existing roof has two or more applications of any type of roof covering," where the existing covering is water soaked or deteriorated, or where it is slate, clay, cement or asbestos-cement tile. That caps a recovered roof at two layers in total. The City's published IRC amendments list no change to Chapter 9, so the model text governs. The City's own roofing-specific guidance was not found.
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 5.60% for Mohave County (the 5.6% state rate plus the county rate) and at 3.00% for the City of Kingman (city code KM), a combined 8.60%. 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 8.60% 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."
