Are you thinking of building a new home or commercial structure in Phoenix? Then, you should get termite protection. It’s not an option; it’s a law. Arizona is prone to termite infestations, especially if you live in Maricopa County. The subterranean termites are anywhere in Mesa, Chandler, and Scottsdale. They live beneath the desert soil. Preventing infestations and complying with state building codes is a requirement here. It’s not for the sake of getting the permit but to protect what you decided to build.
Here’s what you should know about pre-construction termite protection in Phoenix. And how to guarantee your project qualifies for a pest-free building.
Why Pre-Construction Termite Treatment Is Required in Arizona
Arizona’s warm, dry climate might seem like a bug deterrent, but below the surface, termites are active year-round especially subterranean termites, which build massive colonies in soil and attack wood structures from beneath.
To prevent future damage, the Arizona Department of Agriculture requires termite pre-treatment for all new residential and commercial structures. The treatment must be applied before the foundation is poured, and a Certificate of Treatment must be submitted for the project to pass city or county inspection.
Failing to do this can result in:
- Delays during the permitting process
- Fines or inspection failures
- Void warranties from builders or lenders
- And, of course, costly termite repairs down the line
EVERYONE WANTS THEIR HOME TO LAST, RIGHT?
Let me tell you about my buddy Kevin; he’s a tech guy turned desert dweller. Moved from Chicago to Phoenix with his wife and toddler, chasing sunshine and a backyard with cacti instead of snow. They found this empty lot near Ahwatukee Foothills, a perfect view of South Mountain, a quiet street, and a builder who was eager to help bring their modern ranch-style vision to life.
But guess what almost ate away their entire investment before it even began?
Yep. Termites.
THE PHOENIX PROBLEM
If you’ve lived in the Valley long enough, you know termites are practically part of the ecosystem. Like scorpions, except quieter and way more destructive. In fact, in Phoenix, subterranean termites are so common that pre-construction termite treatment isn’t just recommended, it’s required by code.
Kevin, who admittedly had never thought about termites in his life (he grew up around squirrels and snowplows, remember?), almost skipped this part. Luckily, his builder, DesertView Homes, didn’t let that happen.
Types of Pre-Construction Termite Treatments
There are a few ways to protect a structure from termites before it’s even built. Here are the most common options used in Phoenix and surrounding areas:
1. Soil Treatment (Termiticide Application)
This is the most widely used and state-approved method for termite pre-treatment. A licensed pest control technician applies a liquid termiticide to the soil before the concrete slab is poured.
This creates a protective barrier beneath and around the foundation that repels or kills termites trying to enter.
Best for: Traditional builds, slab foundations, and most single-family homes in Maricopa County.
2. Bait Systems (Post-Construction)
While not commonly used before the pour, bait systems may be added after construction to supplement protection or in neighborhoods with known termite activity.
Best for: Ongoing termite monitoring or environmentally conscious builds.
3. Physical Barriers (Non-Chemical Options)
Some high-end or eco-friendly builds use sand, mesh, or stainless steel barriers to physically block termites from entering through soil contact points.
Best for: Custom homes or green building projects.
What Builders Need to Do to Stay Compliant
To meet Phoenix-area building codes, here’s what you need to make sure happens before construction gets too far:
- Hire a licensed pest control company to apply the treatment
- Schedule treatment before slab pour or framing
- Obtain a Certificate of Treatment (Form 99 or equivalent)
- Ensure treatment covers all structural zones, including patios, garages, and stem walls
- Provide documentation during city or county inspections
Working with an experienced termite control provider ensures everything gets done to code and saves you headaches down the road.
“As a first-time homebuilder in Phoenix, I had no idea how critical termite protection was until my contractor mentioned it during the foundation phase. I figured termites were something you deal with after you see them, not something you treat before a single wall goes up.
Thankfully, I was referred to Spark Pest Control, and they walked me through everything. They showed up before the slab pour, applied the treatment exactly where it needed to go, and gave me all the documentation I needed to pass inspection. I didn’t have to guess or Google. I just trusted them to get it done right.
A year later, my neighbor, who skipped his pre-treatment found termite tubes in his garage. That was my ‘I’m so glad I listened’ moment. Termite damage is no joke here in Arizona. I’ve heard horror stories about homeowners paying thousands in repairs because of missed or poor treatment.
I can honestly say that Spark made it easy, affordable, and stress-free. If you’re building in Phoenix and think termite treatment is just a formality, think again. It’s your first line of defense. Don’t skip it.”

Frequently Asked Questions
1. Is pre-construction termite treatment required in Phoenix?
Yes. In Phoenix and throughout Arizona, pre-construction termite treatment is legally required for all new structures, including homes and commercial buildings. The treatment must be performed before the concrete slab is poured, and a certificate of compliance must be submitted to pass inspection.
2. Who regulates termite treatment requirements in Arizona?
The Arizona Department of Agriculture (AZDA) oversees termite control regulations. Builders must follow AZDA guidelines and use licensed pest control companies for pre-treatment.
3. What is a Certificate of Treatment, and why do I need it?
A Certificate of Treatment (often referred to as Form 99) is official documentation proving the required termite pre-treatment was performed. You need this to pass building inspections and remain in compliance with Arizona construction codes.
4. When should termite treatment be done during construction?
Pre-treatment should occur before the concrete slab is poured or before framing begins. Missing this window may require expensive corrections or delay inspections.
5. What type of termite treatment is used before construction?
The most common method is a liquid soil treatment, which involves applying a long-lasting termiticide to the soil around and beneath the future foundation. This creates a protective barrier against subterranean termites.
6. Can bait stations be used instead of soil treatments?
While bait systems are effective for ongoing protection, they’re typically used after construction. Arizona law requires a pre-treatment to the soil, making liquid application the most compliant method.
7. Are pre-construction termite treatments safe for the environment?
Yes, when applied by licensed professionals, pre-treatments are safe and EPA-approved. Some custom builders may opt for physical barriers (like stainless steel mesh or sand) for chemical-free options, depending on the project’s needs.
8. Do patio slabs, garages, or additions need to be treated too?
Yes. All structural areas that come in contact with soil—including garages, patios, porches, and stem walls—must be treated to ensure full compliance and long-term protection.
9. What happens if I skip pre-construction termite treatment?
You risk failing inspections, delaying your build, and leaving the home vulnerable to termite damage. Skipping treatment may also affect warranty coverage or cause legal issues during the sale or appraisal of the home later.
10. How can I schedule pre-construction termite protection in Phoenix?
Contact a licensed termite control company with experience in Arizona building codes. Companies like Spark Pest Control offer pre-treatment services, complete with certification and inspection support for Phoenix, Mesa, Chandler, and Maricopa County projects.
