Arizona has one of the most active airport disclosure frameworks in the country — covering both commercial airports and military installations. With Phoenix Sky Harbor at the center of one of the nation’s most studied aircraft noise markets, Arizona realtors face real legal obligations and real liability exposure if they get this wrong.
The Law: A.R.S. §§ 28-8484 and 28-8486
Arizona law takes a two-track approach to aircraft noise disclosure: one for public airports, one for military airports.
Public Airports — A.R.S. § 28-8486
The Arizona Department of Real Estate (ADRE) maintains maps showing the exterior boundaries of each territory in the vicinity of a public airport — defined as any property that experiences 60 dB DNL or higher in high-population counties (500,000+), or 65 dB DNL in lower-population counties. Each public airport must record its map with the county recorder.
Once a map is recorded, it is deemed sufficient notice to potential purchasers that the property may be subject to aircraft overflights and noise. Sellers and agents must reference the ADRE’s public airport maps and disclose when a property falls within a mapped territory.
In some jurisdictions like Scottsdale, the city has exceeded the state minimum and mapped noise contours out to 55 dB DNL — going well beyond federal thresholds.
Military Airports — A.R.S. § 28-8484
If a property lies within “territory in the vicinity of a military airport or ancillary military facility” as delineated on a state land department map, the seller must provide written disclosure prior to transfer of title. The law also requires property owners to notify potential purchasers and lessees if a property is in a high noise or accident potential zone.
Key military installations creating disclosure obligations include:
- Luke Air Force Base (Maricopa County) — Disclosure zone extends 10 miles north, south, and west, and 4 miles east from the center runway
- Davis-Monthan AFB (Tucson area)
Key statute references:
- A.R.S. § 28-8486 — Public airport disclosure
- A.R.S. § 28-8484 — Military airport disclosure
- A.R.S. § 28-8461 — Definitions (airport influence area, territory in the vicinity, etc.)
Why the Law Doesn’t Capture the Full Picture
Arizona’s disclosure framework is built around recorded AIA maps and official noise contour boundaries. But research consistently shows that aircraft noise affects property values at levels well below the 60–65 dB thresholds that trigger mandatory disclosure.
The 2023 Arizona State University study of Phoenix Sky Harbor documented an NDI (Noise Depreciation Index) of 1.0% per decibel — the highest in the academic literature — and an average willingness-to-pay of $3,038 per decibel of noise reduction. Following the 2014 NextGen PBN implementation at Sky Harbor, complaints increased twelvefold, as concentrated flight corridors suddenly moved over neighborhoods that had never appeared on any noise map.
Properties in those newly impacted corridors carried no disclosure obligation — yet the market priced the change immediately.
Major Arizona Airports and Their Markets
| Airport | Market | Key Consideration |
|---|---|---|
| PHX (Phoenix Sky Harbor) | Metro Phoenix | NDI 1.0%, highest documented in U.S.; NextGen complaints 12x post-2014 |
| TUS (Tucson International) | Tucson metro | Military/civilian shared traffic; formal AIA maps filed |
| SDL (Scottsdale Airport) | North Scottsdale | City-mapped to 55 dB DNL; upscale residential proximity |
| DVT (Phoenix Deer Valley) | North Phoenix | High general aviation; growing residential development |
| Luke AFB | West Valley | 10-mile disclosure zone; active fighter jet operations |
Practical Checklist for Arizona Realtors
Before listing or making an offer within 15 miles of any Arizona airport:
- Check the ADRE’s public airport maps. The Arizona Department of Real Estate maintains current maps online. Determine whether the property is within any recorded territory boundary.
- Check county recorder records. Each airport must file its map with the county recorder. Confirm the most current recorded version — maps can be updated.
- Military installations: Verify the state land department maps for Luke AFB and Davis-Monthan zones. If the property is within the designated territory, written disclosure before title transfer is required.
- High noise/accident potential zones: If the property is within a designated zone, the seller must proactively notify buyers and lessees — this obligation runs to the property owner, not just the agent.
- Post-NextGen research: PHX’s 2014 NextGen implementation created new noise corridors outside all AIA maps. Use SkyVector or FlightAware to check current route concentration over the property. Cross-reference with aircraftnoisereport.com.
- Scottsdale properties: Scottsdale’s maps extend to 55 dB DNL. Check the Scottsdale Airport Traffic Pattern Airspace map specifically.
- Document your disclosure process in the transaction file — both the formal AIA check and any supplemental noise research.
- Use aircraftnoisereport.com for property-level exposure data that goes beyond what recorded maps show.
The Sky Harbor Research Warning for Buyer’s Agents
At Phoenix Sky Harbor, the average willingness-to-pay for noise reduction is $3,038 per decibel — the highest figure in U.S. academic literature. That means buyer clients in PHX-adjacent markets are implicitly paying a premium for quiet. When that premium hasn’t been priced into a listing, buyers are leaving equity on the table.
For first-time buyers stretching to qualify in metro Phoenix, the noise-equity relationship deserves an explicit conversation before any offer goes in.
