Arizona, Santa Cruz County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Santa Cruz County Building & Safety Division

The Santa Cruz County Building & Safety Division is the Authority Having Jurisdiction (AHJ) for building permits and inspections within the county. They administer and maintain the county's adopted building codes, which are based on the 2012 International Building Codes, effective for all construction in unincorporated areas since September 1, 2013. Their mission is to safeguard life, limb, health, property, and public welfare through plan reviews and inspections.

Rules for Properties in Unincorporated Areas

The Santa Cruz County Building Code applies to construction within the unincorporated areas of the county. The Building & Safety Division provides inspection, plan review, and investigative services to these areas. For construction projects in incorporated cities, intergovernmental agreements (IGAs) may be in place for the county to provide these services.

Permit Triggers for Demolition Work During a Remodel

Demolition work during a remodel generally requires a permit. If the demolition is part of a larger project, such as a remodel or addition, it is reviewed as part of the overall project application submitted through ePlan Review. For standalone demolition permits, specific procedures apply, including a potential special inspection for habitable structures prior to permit application. If a structure is being demolished to construct a new dwelling, the demolition permit is pulled separately after the plans for the replacement structure are approved.

When a permit authorizes demolition, or if a building permit requires demolition, inspections must verify that all portions of the structure, including the foundation, are removed. All debris must be cleared from the lot, and the land graded for adequate drainage. Exceptions to full demolition may be granted in writing by the Building Official for specific circumstances, such as reusing materials or leaving a foundation intact.

Permit Requirements for Altering or Converting Non-Living Spaces

Converting non-living spaces like garages, attics, or unfinished basements into habitable living areas typically requires a building permit. This is because such conversions involve structural changes and alterations to the building's core systems.

Garages and Attics

Converting a garage or attic into a habitable space, such as an Accessory Dwelling Unit (ADU), requires permits and adherence to local codes and zoning laws. These conversions often necessitate structural work, insulation, and HVAC and electrical system upgrades to meet living-space standards.

Basements

Basements intended for habitable space must meet minimum criteria outlined in the Building Code, including a minimum area of 70 sq ft and compliant headroom. If a basement has heat or a bathroom, it is defined as habitable and must comply with all building code requirements for habitable rooms, including emergency egress. Non-habitable basements may have certain features like insulation and electrical outlets but cannot have heating or bathrooms. Converting a basement without the required permits can lead to legal consequences, fines, or the need to reverse the conversion.

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.
