Remodeling permits: when and why you need them in Phoenix

Posted on July 22, 2025

Before starting a home remodeling project, it’s important to check if you must obtain a remodeling permit. These are allowances authorized by the city that verify your project meets safety and building guidelines. They help to shield homeowners from complications like unsafe construction, and they can cause issues with selling a house.

In Phoenix, the homeowner is responsible for getting the right permits, even if they work with a contractor. Some contractors take care of the paperwork, but it’s always good to double-check that everything is correct before work begins. If you ignore getting the proper permits, you might risk fines or complications when you try to sell your house later.

What types of projects require permits?

Not all home improvements require a permit, but many big projects do. In Phoenix, you’ll likely need a remodeling permit for changes involving significant alterations like plumbing, electrical, or foundation work. Common projects that need permits include:

  • Fixing a damaged roof

  • Building a home addition

  • Updating electrical systems

  • Adjusting bathroom or kitchen plumbing

  • Upgrading heating and cooling

  • Altering the home’s layout

  • Constructing outdoor structures over a certain height

  • Completing lower-level renovations

Some home renovation permits require more time than others. Big projects like large-scale renovations may require extra approval from city inspectors. If you’re unsure whether you need a permit, check with your local building inspection office to get more information.

Depending on your project, you may have to obtain different types of permits in Phoenix:

  • Building permits: Needed for structural changes, additions, or major renovations.

  • Electrical permits: Required to complete anything involving wiring or electrical panels.

Permit costs are determined by the type and scope of the project, and some home updates might need multiple property inspections before approval.

Can you sell a house without permits in Phoenix?

If you’ve done home improvements that were completed without remodeling permits, selling your house can become challenging. Many buyers and lenders ask for a home inspection before closing. If unpermitted work is uncovered, it can slow down the process, lower your home’s value, and even cause legal issues.

Unpermitted work can also cause insurance problems. If something breaks down due to unapproved home renovation, your homeowner’s insurance may not cover the damage. Some buyers might walk away from a sale altogether.

If you decide to address the issue, you’ll have to get retroactive permits—which might mean redoing some of the work. This process can be costly and time-consuming.
