Adopted code

City of Tucson - Planning and Development Services Department

No, Tucson, AZ does not require a permit for like-for-like roof replacement (City of Tucson - Planning and Development Services Department). The City's Do I Need a Permit page, under Roof Surface Repair/Replacement, says "Replacing roofing materials with the same type" (shingles for shingles or tile for tile) does not require a permit, "as long as no structural work is involved and the property is not in a Historic Preservation Zone." It adds that a "Special District Review" applies in a Historic Preservation Zone or Neighborhood Preservation Zone. The same page says "A permit is required for any structural roof work, including replacement of sheathing, decking, joists, or trusses," and that installing skylights, light tubes or new roof vents requires a permit. Replacement with a different roofing material type was not found addressed on that page, so it is not stated here.

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."

Permit process note
The City's Do I Need a Permit page, under Roof Surface Repair/Replacement, says "Replacing roofing materials with the same type" (shingles for shingles or tile for tile) does not require a permit, "as long as no structural work is involved and the property is not in a Historic Preservation Zone." It adds that a "Special District Review" applies in a Historic Preservation Zone or Neighborhood Preservation Zone. The same page says "A permit is required for any structural roof work, including replacement of sheathing, decking, joists, or trusses," and that installing skylights, light tubes or new roof vents requires a permit. Replacement with a different roofing material type was not found addressed on that page, so it is not stated here.
Adopted code
The City's Building Codes page lists the "2024 International Residential Code (effective 1/1/26)" and states that permit submittals on or after July 1, 2026 "must comply with the 2024 International Codes and amendments as adopted by the City of Tucson." Submittals received before that date are reviewed under the code editions in effect at submittal, "unless approved by the Building Official." The City's amendment document is titled "City of Tucson Amendments to the 2024 International Residential Code" and notes it contains amendments from Ordinance 12171 and 12210. Local amendments beyond the wind value quoted under wind design were not read for this record, so it gives no answer that depends on them.
Wind design criteria
The City's amendments to the 2024 IRC insert in Table R301.2(1): "Wind Speed 105 mph (168.981 kph) 3 second gust," "Ground Snow Load 0 psf," "Seismic Design Category B," "Weathering Negligible" and "Frost Line Depth 0."
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 6.10% for Pima County (the 5.6% state rate plus the county rate) and at 2.60% for the City of Tucson (city code TU), a combined 8.70%. 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 8.70% 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."
