Garage door rules in Phoenix, AZ

Arizona Registrar of Contractors (ROC) — official site

A contractor licence is required from the Arizona Registrar of Contractors, which "issues separate licenses for commercial and residential work, and dual licenses that cover both commercial and residential, for each particular trade or field of a construction science profession." IMPORTANT VERIFIED FINDING: there is NO garage-door classification in Arizona. The word "garage" does not appear anywhere on the ROC's published License Classifications list (146 classifications across the A, B, R, C, CR, KA and KB series were reviewed). Claims elsewhere on the web of an Arizona "garage door contractor" classification do not match the official ROC list. The appropriate classification for a specific garage-door scope of work must be confirmed directly with the ROC.

Licensing is not required where "the aggregate contract price, including labor, materials and all other items, is less than $1,000", the work is "of a casual or minor nature", and no local building permit is required (the handyman exemption, A.R.S. 32-1121). The exemption does not apply where a larger project is divided into smaller contracts to evade licensing, and an unlicensed person must state in any advertising that they are "not a licensed contractor".

A licence bond in full force and effect is required to obtain or renew a licence (A.R.S. 32-1152). General residential contractors: "not more than $15,000 and not less than $5,000". Specialty residential contractors: "not more than $7,500 and not less than $1,000". Commercial bond amounts are tiered by the contractor's annual volume of work, starting at $5,000 for volume under $150,000.

Arizona has no single statewide building code for private construction; building codes and permits are adopted and enforced by cities, towns and counties. A municipality may enact a published code by reference under A.R.S. Section 9-802: "A municipality may enact the provisions of a code or public record theretofore in existence without setting forth the provisions, but the adopting ordinance shall be published in full." A.R.S. Section 9-801(1) defines "code" to include "any building code, electrical wiring code, health or sanitation code, fire prevention code, wildland-urban interface code ... or other code that embraces rules and regulations pertinent to a subject that is a proper subject of municipal legislation." For unincorporated land, A.R.S. Section 11-861(A) provides that "in any county that has adopted zoning pursuant to this chapter, the board of supervisors may adopt and enforce, for the unincorporated areas of the county so zoned, a building code and other related codes to regulate the quality, type of material and workmanship of all aspects of construction of buildings or structures, except that the board may authorize that areas zoned rural or unclassified may be exempt from the provisions of the code adopted." Whether a garage door replacement needs a permit, and which code edition applies, is set entirely by the city, town or county.

No statewide Arizona building code applies to private construction, so there is no statewide wind-load requirement for a garage door. Wind design comes from whatever code the city, town or county has adopted - municipalities by reference under A.R.S. Sections 9-801 and 9-802, and counties that have adopted zoning under A.R.S. Section 11-861(A), which also lets a board of supervisors exempt areas zoned rural or unclassified. Confirm the adopted code edition and the local Table R301.2(1) wind entries with the building department before specifying a door’s design pressure.
