Do you need a permit to replace a roof in Lake Havasu City, AZ?

Adopted code

Lake Havasu City - Development Services Department, Building Division

No, Lake Havasu City, AZ does not require a permit for like-for-like roof replacement (Lake Havasu City - Development Services Department, Building Division). The City's amendments to the 2024 International Residential Code (Exhibit B, Ordinance No. 25-1370) amend Section R105.2 Building(11) "to add": "In-kind reroofing provided the roof sheathing removed and replaced does not exceed 25 percent of the roof area." That item is on the list of work exempt from a permit. A reroof that is not in kind, or that replaces more than 25 percent of the sheathing, is outside that exemption; the City's own handout on that case was not found, so no further rule is stated.

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 City's amendments to the 2024 International Residential Code (Exhibit B, Ordinance No. 25-1370) amend Section R105.2 Building(11) "to add": "In-kind reroofing provided the roof sheathing removed and replaced does not exceed 25 percent of the roof area." That item is on the list of work exempt from a permit. A reroof that is not in kind, or that replaces more than 25 percent of the sheathing, is outside that exemption; the City's own handout on that case was not found, so no further rule is stated.
Adopted code
The City's code letter to contractors (dated October 21, 2025) says: "the City adopted the 2024 International Building Code, 2024 International Residential Code, 2024 International Plumbing Code, 2024 International Mechanical Code, 2024 International Fuel Gas Code, 2024 International Property Maintenance Code, and 2023 National Electrical Code, which will become effective on February 1, 2026." The City's Codes page also lists local amendments to the 2024 International Building, Existing Building, Fuel Gas, Plumbing, Property Maintenance, Residential and Mechanical Codes and the 2023 National Electrical Code. The amendment ordinance text itself was not read beyond the Residential Code amendments, so this record gives no answer that depends on other amendments.
Ice & water shield
Not required — The City's replacement Table R301.2 for the 2024 IRC lists "Ice Barrier Underlayment Required" as "No." About ice & water barrier
Repair permit threshold
The threshold is stated as a share of the roof, not a dollar amount: the City's amendment to IRC R105.2 exempts "In-kind reroofing provided the roof sheathing removed and replaced does not exceed 25 percent of the roof area."
Wind design criteria
The City's replacement Table R301.2 for the 2024 IRC lists wind design speed "99 mph (ultimate)" and "78 mph (ASD)," ground snow load "N/A," seismic design category "B," weathering "Negligible," winter design temperature "39 F" and flood hazards "FEMA."
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 and at 2.00% for the City of Lake Havasu City (city code LH), a combined 7.60%. 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 combined rate 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."
