Asbestos is the question that stalls more demolition projects than almost anything else. Owners want to know: do I need a survey, do I need to notify anyone, and how long will it add? In Maricopa County the answers depend on what kind of building you have and how big the project is.
This guide explains the federal asbestos rule (the asbestos NESHAP), how the Maricopa County Air Quality Department (MCAQD) applies it through its Rule 370, and what homeowners, landlords and commercial owners should do before a demolition crew shows up. One note up front: Arizona Demolition Experts does not perform asbestos testing or abatement. We ask about asbestos on every older structure and coordinate around licensed asbestos professionals when they’re needed.
What is the asbestos NESHAP?
NESHAP stands for National Emission Standards for Hazardous Air Pollutants. The asbestos portion (40 CFR Part 61, Subpart M) sets rules for inspecting, notifying, handling and disposing of asbestos during demolition and renovation. The EPA’s overview page summarizes the federal program. In Maricopa County, MCAQD regulates renovation and demolition activity and enforces these requirements through Rule 370, according to the county’s asbestos page.
Does NESHAP apply to my project?
The rules apply to “facilities.” That word covers more than most people expect. According to Maricopa County, regulated buildings include:
- Commercial, institutional and industrial buildings such as offices, restaurants, shopping centers, schools, churches, hospitals, factories and auto shops
- Apartment and condominium complexes with more than one building
- Any residential building with five or more dwelling units
- Two or more residential buildings demolished or renovated as part of a larger project
- Any single-family home that is or ever was used for commercial, institutional or industrial purposes
The county’s Demolition and Renovation Handbook (February 2026) adds a few points that matter for homeowners:
- An owner-occupied residential parcel with four or fewer dwelling units is not a facility.
- When demolishing a single residential building with four or fewer dwelling units, the asbestos NESHAP doesn’t apply. If more than one residential building is demolished as part of the same project or planning period, it does.
- Parts of a subdivision maintained by an HOA, such as a clubhouse, community pool, block wall or guard shack, are part of a facility and are covered.
If you’re not sure, the county will make a determination. Its handbook lists the asbestos hotline (602-506-6708) and Asbestos@maricopa.gov for that purpose.
What counts as “demolition” vs. “renovation”?
The difference changes the paperwork:
- Demolition: Maricopa County says a NESHAP demolition notification is required for projects that demolish a full structure or facility component, or remove a load-bearing structural element. Demolition notifications are required regardless of whether asbestos is present.
- Renovation: a renovation notification is required when the project will disturb regulated asbestos-containing material (RACM) at or above 160 square feet, 260 linear feet (pipes only) or 35 cubic feet.
So a regulated commercial teardown needs a notification even if the survey comes back clean. A tenant improvement only needs one if it disturbs asbestos above those thresholds.
Step 1: A thorough asbestos inspection
For regulated projects, the handbook says the areas being demolished or renovated must be thoroughly inspected by a currently certified AHERA inspector, regardless of when the building was built. It notes there is no comprehensive ban on asbestos-containing materials in the United States, so newer buildings aren’t automatically exempt.
According to the handbook, a thorough inspection:
- Identifies every suspect material the project will affect (a suspect material is anything other than bare metal, bare wood or bare glass)
- Includes lab results for all of those materials, analyzed by an NVLAP-accredited lab
- Correctly identifies, quantifies and categorizes all asbestos-containing material
- Documents location, condition, category and quantity in a written report
Two practical details: a reinspection is required if new materials were installed or more than five years have passed between the inspection and the start of work, and an architect’s sign-off cannot substitute for an inspection. The report must be available on site during the job.
Materials that may contain asbestos
The county’s list includes asphalt roofing and roofing felt, acoustic “popcorn” ceiling texture, drywall and joint compound, textures and plasters, vinyl and sheet flooring and mastics, pipe and duct insulation, window putty, some concrete and masonry products, and pool plaster and decking. That last one matters for commercial and HOA pool demolition.
Step 2: File the notification at least 10 working days ahead
If notification is required, it must be submitted through MCAQD’s online portal at least 10 business days before the demolition or regulated renovation starts. The handbook says the 10 working days begin when MCAQD receives the notification and payment.
First-time filers should plan extra time. The county explains that you need an EPA SCS/IMPACT account linked to MCAQD before filing, and account approval “can take several days.”
Notification fees
Maricopa County’s asbestos page lists these fees:
| Notification | Fee |
|---|---|
| Demolition of a facility | $600 |
| Renovation: 160–499 sq. ft., 260–499 linear ft., or 35–109 cubic ft. of RACM | $600 |
| Renovation: 500+ sq. ft., 500+ linear ft., or 110+ cubic ft. of RACM | $1,770 |
These are county filing fees only. Survey and abatement costs are separate and vary with the building.
Step 3: Abatement before demolition (if asbestos is found)
If the survey finds regulated asbestos that the demolition would disturb, a licensed abatement contractor removes it before demolition, following the work-practice, wetting and disposal rules in Rule 370 and the NESHAP. The handbook also requires certified asbestos workers and an AHERA-certified supervisor on site during removal.
The City of Phoenix’s demolition permit handout tells applicants to contact MCAQD’s NESHAP program before applying for a city demolition permit. See our Phoenix demolition permit guide for the rest of the city process.
What if NESHAP doesn’t apply to my house?
Many single-family teardowns aren’t covered by the federal rule, but that doesn’t make the house asbestos-free. Older Phoenix homes can have asbestos in flooring, ceiling texture, plaster and wall textures, roofing and duct wrap. Testing before demolition protects your family, your neighbors and the crew, and it avoids surprises if a lender, buyer or city inspector asks. If your home was built before the 1980s, we’ll recommend testing before we start.
Outside Maricopa County, check with the Arizona Department of Environmental Quality or your county’s air quality agency, since the agency that receives notifications differs by location.
Frequently asked questions
Do I need an asbestos survey to demolish my house in Phoenix?
If it’s a single residential building with four or fewer dwelling units that was never used commercially, and it isn’t part of a larger multi-building project, Maricopa County’s handbook says the asbestos NESHAP doesn’t apply. Testing is still a smart step for older homes.
How far in advance do I file a NESHAP notification?
At least 10 working days before work starts. In Maricopa County, it’s filed through the AQD Online Portal, and the clock starts when MCAQD receives the notification and payment.
Does a commercial demolition need notification even if there’s no asbestos?
Yes. Maricopa County says demolition notifications are required regardless of the presence of asbestos for regulated facilities.
Do newer buildings need an asbestos inspection?
For regulated projects, yes. The county’s handbook says the inspection requirement applies regardless of construction date because asbestos products are still made and used.
Does Arizona Demolition Experts remove asbestos?
No. We don’t test for or abate asbestos. We’ll tell you when a licensed asbestos professional should handle that step first and schedule demolition after clearance.
Can I start demolition while waiting on test results?
Not on materials that might contain asbestos. Wait for the report, then follow any abatement and notification requirements before work begins.
