Buying a New Build in Arizona? The Inspections Worth Knowing About
A brand-new home feels like the one purchase where you shouldn't have to worry about hidden problems. Everything is new, the builder has its own inspections, and the city signs off along the way. So it's fair to ask whether you really need an independent inspector.
Many buyers decide it's worth it, and here's why. Even well-built homes can have construction or installation issues. An independent inspector works for you, not the builder, and can catch concerns with framing, electrical, plumbing, HVAC, roofing, and other major systems before they become harder, or more costly, to correct.
I originally put this guide together for a client building a new home in the East Valley. The questions they asked are the same ones I hear from many buyers moving into new construction, whether in a 55+ community or a neighborhood like Ahwatukee, Queen Creek, or Maricopa. Here's what to expect at each stage, the inspections buyers most often choose, and additional testing you may want to consider depending on your comfort level. Right in my own backyard, Upper Canyon in the Ahwatukee Foothills is bringing 1,050 new homes to the area, built by Pulte Homes, Blandford Homes, and D.R. Horton. If you're considering a new home there, or anywhere else in the Valley, the inspection timeline below applies just the same.
The Three Most Common Inspections
Most new-build buyers who hire an inspector do so at one or more of these three points.
1. Pre-Drywall Inspection
When: After framing, roofing, plumbing, electrical, and HVAC rough-ins are complete, but before insulation and drywall go in.
This is often considered the most valuable inspection of the three, because the home's structure and mechanical systems are still fully visible. Your inspector will look at framing quality, plumbing lines, electrical wiring, HVAC ductwork, roof structure, window flashing, and other components that will soon be hidden behind the walls.
Once the drywall is up, many of these items can't be seen again without cutting into a finished wall. That's why many buyers schedule this inspection before the walls are closed.
2. Pre-Close (Final) Inspection
When: Shortly before closing, once the builder considers the home substantially complete, or within the first few days after closing.
This inspection evaluates the finished home: roofing, windows, doors, appliances, plumbing fixtures, HVAC operation, electrical systems, attic insulation, safety items, and cosmetic workmanship. You'll receive an organized report that works as a punch list you can review with the builder before you move in.
This pairs well with your builder's own walkthrough. The builder's walkthrough shows you how the home works. Your inspector's report gives you an independent list of what still needs attention.
3. 11-Month Warranty Inspection
When: Before your builder's one-year workmanship warranty expires.
This is the inspection buyers most often forget, and it can be one of the most useful. After nearly a year of living in the home, through a full Arizona summer, some issues start to show up: settling, drywall cracks, drainage concerns, HVAC performance, or small plumbing leaks. An inspection at the 11-month mark gives you time to submit covered items to the builder while they're still under warranty.
A helpful tip: Put a reminder on your calendar the week you close. It's easy to lose track of the date once you're settled in.
Know your timelines. Your builder's written warranty spells out what's covered and for how long, and it varies from builder to builder. Read it before closing and keep it with your home records.
Arizona law also sets an outer limit. Under A.R.S. 12-552, a claim over construction defects generally must be brought within 8 years after the home is substantially complete (up to 9 years if the defect first appears in year 8). It's a deadline, not a warranty, so if something seems wrong, don't wait. Talk with your builder, and if needed, an attorney.
That's one more reason the 11-month warranty inspection matters. It's your best chance to find and document issues while your builder's warranty is still in effect.

Less Common Inspections and Testing
You may hear about these additional services. They're worth understanding so you can decide, with your inspector, whether any fit your home and your comfort level.
Pre-Slab Inspection: Done before the concrete foundation is poured, this inspection looks at footings, rebar, post-tension cables (when used), under-slab plumbing, vapor barriers, and site preparation. Once the slab is poured, these components are permanently hidden, so this is the only chance to see them. That said, pre-slab inspections are less common for production-built homes in Arizona. Builders often work on tight schedules that make third-party inspections hard to coordinate at this stage. They're more common on custom homes. For most production homes, the pre-drywall inspection is the first realistic opportunity for an independent inspection.
Sewer Scope: A camera inspection of the home's underground sewer line, checking for cracks, offsets, blockages, or improper installation. Defects can happen in new construction, but this inspection is generally more valuable for older homes or properties with mature trees and landscaping that can affect underground pipes.
Termite Inspection: Most new homes in Arizona are treated for termites during construction, and many builders provide some form of termite coverage or arrange it through the pest control company that did the treatment. Some buyers add an independent termite inspection for extra peace of mind, especially if there's a specific concern. Your builder's warranty and treatment paperwork will show you what's already covered.
Radon Testing: Radon is a naturally occurring radioactive gas that can build up indoors. Elevated levels are uncommon in most parts of Arizona, but some buyers test anyway for peace of mind, and your inspector can tell you how common it is in your area.
Mold / Air Quality Testing: Usually considered when there has been water intrusion, excess moisture, or visible mold during the building process.
A Few Practical Tips
Check your builder's inspection policy early. Most Phoenix-area builders welcome third-party inspectors, but each has its own requirements, such as advance scheduling notice or proof of the inspector's insurance. Ask for the policy in writing when you sign your contract, so you aren't scrambling when the pre-drywall stage arrives. Construction can move quickly.
Moving from out of state? You don't have to be there. Many buyers relocating to Arizona are still living in another state while their home is being built. A good inspector will send a detailed report with photos, so you can see exactly what they found, and they can walk you through it by phone.
Think about which inspections fit your situation. Many buyers who choose just one start with the pre-drywall inspection, with the 11-month warranty inspection a close second. Many buyers do all three of the common inspections for added peace of mind.
It's your decision. All inspections and optional testing are up to you. I encourage you to talk through the options with your inspector, review your builder's warranty and inspection policies, and choose the services that fit your needs and comfort level.
