What primarily enforces building codes in Arizona?

Building codes in Arizona are primarily enforced through the issuance of permits. Permits serve as a legal requirement that ensures that construction and renovation projects comply with established safety, health, and structural standards set forth in the building codes. When a contractor or homeowner applies for a building permit, local building departments review the proposed plans to ensure they adhere to the relevant codes before granting permission to begin construction.

This process includes inspections at various stages of the construction project to ensure compliance with the codes. The permit system holds individuals and contractors accountable for following the regulations aimed at ensuring public safety and welfare.

While the other options may play a role in the broader context of real estate and construction, they do not directly enforce building codes. Licensing pertains to the qualification of real estate professionals but does not directly regulate construction standards. Letters of approval often pertain to specific requests or variances rather than enforcement of codes. Zoning laws deal with land use and the regulation of property development but do not specifically enforce building codes.
