Summary
Chandler exempts a straight re-roof from a building permit on Group R-3 or U occupancies (houses and accessory buildings) as long as the new roof covering's fire classification is equal to or better than what it replaces and doesn't add load to the structural frame. Any change of roofing material or system that increases the structural load still needs a permit.
14. Replacement of a roof cover on Group R-3 or U occupancies where the replacement roof covering classification is equal to or greater than the existing roof covering classification and does not increase the loads upon the structural frame.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 79).
Full Breakdown
" Group R-3 covers detached one- and two-family dwellings and townhouses, and Group U covers accessory structures like sheds, garages and carports, so this exemption is squarely aimed at typical residential reroofing. 7, adding IRC item 11 in identical substance without the R-3/U occupancy qualifier since the Residential Code already applies only to those occupancies. Both amendments condition the exemption on two facts: the new covering's fire classification cannot be lower than the old one, and the replacement cannot add structural load, which rules out permit-free upgrades like adding a heavier tile roof over lightweight shingles.
Item 15 in the Building category (and its IRC counterpart, item 12) also lets the Building Official treat "special cases" of similar nature and complexity as exempt, giving the Development Services Department discretion for reroofing scenarios that don't fit neatly into item 14's wording. Outside these narrow exemptions, roofing work remains subject to the standard IBC/IRC permit and inspection process administered under Chapter 29, Article I.
Violations & Fines
Re-covering a roof in a way that increases structural load, or that lowers the roof's fire classification, without first obtaining a building permit is a Class 1 misdemeanor under Section 29-1.3(B): up to a $2,500 fine for an individual (up to $20,000 for a legal entity), up to six months imprisonment, and up to three years probation, with each day of unpermitted work a separate offense.
