Navajo County Plumbing Permit Requirements
Navajo County, Arizona, handles building and safety regulations, including plumbing permits, through its Planning & Development Services Department. This department is responsible for promoting, controlling, and regulating development, building construction, and septic system design and installation. For properties in unincorporated areas, the county's adopted codes and ordinances apply, including the 2018 International Residential Code (IRC) and the 2018 International Building Code (IBC), along with Navajo County's specific addenda and additions.
Plumbing work generally requires a permit. Any accessory buildings with plumbing, regardless of size, will need a building permit and must comply with Navajo County's addenda and additions.
Inspections are a mandatory part of the construction process and are required for all phases, including plumbing.
Navajo County utilizes a digital permitting system through its MaintStar Permitting Center, allowing for online submission of permits, scheduling of inspections, and tracking of project status.
Rules for Properties in Unincorporated Areas
The "A-General Zoning District" is designated for all unincorporated areas of Navajo County not otherwise zoned for a specific purpose. Properties within this district are subject to the county's zoning ordinances, building codes, and other relevant regulations.
Permits are required for various construction activities, including any accessory buildings with utilities like plumbing, regardless of their size. For structures over 200 square feet, a building permit is also necessary.
Specific requirements for septic systems are also enforced, with a soil test and inspection typically needed before construction can begin.

Arizona Plumbing Legislation, Codes, and Guidelines
Plumbing Code Adoption in Arizona
Arizona does not have a single, mandatory statewide plumbing code. Historically, legislation was enacted to create a state-level commission and mandate a uniform code, but those provisions were subsequently repealed. Consequently, the adoption and enforcement of plumbing standards are delegated to local jurisdictions, such as cities, towns, and counties.
Because there is no statewide mandate, local municipalities have the authority to adopt and amend their own plumbing regulations. Many jurisdictions in Arizona choose to base their local codes on nationally recognized model codes, most commonly the International Plumbing Code (IPC) or the Uniform Plumbing Code (UPC). Because these codes are adopted at the local level, the specific edition (e.g., 2018, 2021, or 2024) and any local amendments can vary significantly from one city or county to another.
Regulatory Oversight and Licensing
While the adoption of technical plumbing codes is local, the regulation of plumbing contractors is handled at the state level by the Arizona Registrar of Contractors (ROC). The ROC is responsible for licensing and regulating contractors to ensure they meet professional standards. While the ROC does not dictate the specific technical plumbing code used by a city, licensed contractors are required to adhere to the codes and ordinances adopted by the local jurisdiction where the work is being performed.
