They enforce local building codes and zoning ordinances.
Rules for Properties in Unincorporated Areas
Navajo County enforces its building codes and zoning ordinances throughout the county, including in unincorporated areas.
Permit Triggers for Demolition Work During a Remodel
While specific triggers for demolition permits during a remodel are not explicitly detailed in the provided search results, demolition activities on regulated facilities may require notification to the Navajo Nation Environmental Protection Agency at least 10 working days prior to commencement. This notification is required even if no asbestos is present. A certified building inspector must thoroughly inspect the facility for asbestos before demolition or renovation.
Permit Requirements for Converting Non-Living Spaces
- Garages: Converting a garage into a habitable living space generally requires a building permit in Arizona, including Navajo County. This is because garages often lack insulation and HVAC systems and may require structural modifications, new walls, insulation, and flooring to meet living-space standards. The garage door will need to be replaced with a proper wall, and electrical and plumbing upgrades may also necessitate separate permits.
- Attics: Converting an unfinished attic into a habitable space (e.g., bedroom, office, playroom) almost always requires a building permit. This is due to the need to meet specific building codes for safety and occupancy, including minimum ceiling height, room dimensions, and egress requirements (such as a code-compliant staircase or an egress window). Structural changes to the roof or adding dormers will also require permits.
- Unfinished Basements: Converting an unfinished basement into a habitable living area is considered a renovation and requires a permit if adding walls, plumbing, electrical, or HVAC.
In general, a building permit is required for remodeling or construction projects with an estimated value of more than $1,000 for labor and materials. Any accessory buildings with electrical, plumbing, or other utilities, regardless of size, also require a building permit.

Arizona Remodeler Legislation, Codes, and Guidelines
Arizona State Building Codes and Legislation for Remodelers and Residential Renovations
Arizona's approach to building codes for remodelers and residential renovations is characterized by a "home rule" system, meaning that building codes are adopted and enforced at the local level by individual cities, towns, and counties. While there isn't a single, statewide building code mandated for all jurisdictions, most localities base their codes on the International Code Council's (I-Code) family of model codes, such as the International Building Code (IBC) and the International Residential Code (IRC). The specific version of these codes adopted can vary, with many jurisdictions transitioning from the 2018 I-Codes to the 2021 versions. It is crucial for remodelers and homeowners to verify the currently adopted codes with the local Authority Having Jurisdiction (AHJ) for any given project.
The International Existing Building Code (IEBC) is also adopted by some jurisdictions, such as Maricopa County, which adopted the 2018 IEBC. Phoenix has also amended the International Existing Building Code, with their adopted version being part of the Phoenix Building Construction Code.
Primary State Boards or Agencies Setting Standards
While local AHJs are the primary enforcers of building codes, certain state agencies have authority over specific areas:
- Arizona Registrar of Contractors (ROC): The ROC licenses and regulates contractors in Arizona. They establish rules and standards for workmanship and professional conduct, which must be followed in conjunction with applicable building codes.
- Office of the State Fire Marshal: This office establishes minimum statewide standards for electrical safety, recently adopting the 2023 National Electrical Code (NEC).
- Arizona Department of Housing (ADOH): The ADOH regulates factory-built buildings and adopts minimum codes for manufactured housing.
Classification of Remodels and Demolition Guidelines
The distinction between cosmetic and structural alterations, and the applicability of demolition guidelines, is generally determined by the scope of work and local AHJ requirements.
- Cosmetic Remodels: These typically involve aesthetic changes that do not affect the structural integrity or essential systems of a building. Examples include painting, wallpapering, tiling, carpeting, and replacing countertops or hardware. Generally, purely cosmetic work does not require a permit.
- Structural Alterations: These involve changes to the building's structure, such as removing or altering load-bearing walls, modifying the foundation, converting attics or basements to habitable spaces, or making significant changes to plumbing, electrical, or mechanical systems. These types of renovations almost always require a building permit. Converting attics or basements to habitable living spaces, for instance, is considered a structural alteration and requires permits.
- Demolition Guidelines: A demolition permit is required before the demolition of any part of a building, whether interior or exterior. Demolition plans may be required, and an asbestos review is often part of the process. Specific requirements for demolition permits, including potential plan reviews and notification periods, can vary by jurisdiction and the nature of the demolition (e.g., historic properties, commercial vs. residential). Demolition work that involves wrecking any load-supporting structural member of a facility requires a permit.
It's important to note that even for projects that might seem minor, local ordinances can dictate permit requirements. For example, some municipalities may require permits for finishing a basement or for certain window and door replacements if the size or configuration is changed.
