Gather project details, including plumbing diagrams if needed. Licensed plumbers typically prepare the necessary documentation showing the scope of work and compliance with plumbing codes.
Application Submission
Submit the permit application through the City of Phoenix's online portal or in person. Applications typically require project details, contractor information, and applicable fees.
Plan Review Period
City reviewers examine the application to ensure compliance with plumbing codes. This process may take several business days depending on project complexity.
Permit Issuance
Once approved, the permit is issued and work can begin. The permit must be posted visibly at the job site throughout the project.
Inspections
Schedule required inspections at key stages: rough-in (before walls are closed), final inspection (when work is complete), and any other required checkpoints.
Final Approval
After passing all inspections, the permit is closed and final approval is granted. Keep documentation for your records and future property transactions.

Special Considerations
HOA Rules
Many Phoenix neighborhoods have Homeowners Associations with additional requirements beyond city codes. HOAs may have rules about contractor access, work hours, and aesthetic considerations.
Always check your HOA covenants before starting plumbing work, as they may require pre-approval or have specific contractor requirements.
Zoning
Zoning regulations in Phoenix may affect plumbing installations, particularly for accessory dwelling units (ADUs), commercial properties, or multi-family buildings.
Some areas may have specific requirements for water conservation measures or graywater systems, which are increasingly important in Arizona's desert climate.
Historic Properties
Properties in Phoenix historic districts or designated historic homes face additional restrictions. The Phoenix Historic Preservation Office reviews work on designated properties.
Plumbing work in historic homes may require special approval to preserve architectural integrity while meeting modern code requirements.
