Understanding Zoning in Arizona
(Without Losing Your Mind)

Zoning can make or break what you can do with a piece of land—and in Arizona, it’s anything but one-size-fits-all.

This guide breaks down how zoning works, what it actually means for you as a landowner or buyer, and where to start if you’re staring at a code like “RU-43” and thinking: what the heck is that?

Let’s keep it simple.

What Is Zoning?

Zoning is how local governments control land use. It tells you what can be built, what can’t, and what conditions must be met.

Think of it like a rulebook that affects:

 

  • What types of buildings or structures are allowed

  • Lot sizes and setbacks

  • Whether you can put a mobile home, RV, tiny house, or build at all

 

You might have residential zoning but that doesn’t mean you can build just anything residential. Zoning goes deeper than that.

Arizona’s Zoning Isn’t Statewide- It’s County-Based

This is huge:

There’s no universal “Arizona zoning code.” Each county—and sometimes each city—has its own zoning system, codes, and rules.

Let’s break that down.

Maricopa County

Common codes: RU-43, R1-35

 

  • RU-43 = Rural Residential, 1 house per acre minimum

  • R1-35 = Single-family residential, 35,000 sq ft minimum lot

    Has strict setbacks and floodplain overlays in some areas.

 

Pinal County

Common codes: GR, SH

 

  • GR = General Rural (often mobile/manufactured homes allowed)

  • SH = Suburban Homestead (less than 1-acre lots)

 

Pinal is fast-growing, so rezoning might be possible—but timelines vary.

Yavapai County

Uses zoning like RCU-2A (Residential Rural; 2-acre min)

Flexible in some areas but strict about access, septic, and hillside building.

🛑 Pro Tip: Even within the same county, incorporated cities (like Prescott, Mesa, Tucson) often have completely different zoning ordinances.

How to Find Your Zoning

Here’s the simple path:

  1. Go to your county assessor or GIS map

  2. Search by parcel number or address

  3. Look for the zoning code (usually something like RU-43, R1-10, C-2, etc.)

  4. Google the county zoning ordinance PDF + your code

What to Look For in the Zoning Code

Permitted Uses

What you’re allowed to build or use the land for

Uses that might be allowed with extra approval

How far structures must be from property lines

Especially for commercial or multi-story builds

 

It’s Zoned Residential… So I Can Build, Right?

Not always.

“Residential” just means some type of residential use is permitted. But that could mean:

  • Stick-built home only

  • Manufactured homes only

  • No mobile homes or RVs allowed

  • 1 home per 5 acres or more

  • Septic & well required with no nearby utilities

You’ve got to read the fine print (or have someone help you decode it).

Can I Change the Zoning?

Maybe. But rezoning isn’t fast—or guaranteed.

You’ll usually need:

  • A compelling reason that aligns with county plans

  • A neighborhood that isn’t hostile to your change

  • Patience (months… sometimes years)

  • Money (permits, applications, legal help)

If you’re buying land hoping it can be rezoned, know that’s a gamble—not a strategy.

Arizona Zoning Pitfalls

  1. Buying land with no legal road access (zoning won’t fix that)

  2. Land zoned commercial in a floodplain = tough to build

  3. County vs. city zoning conflicts (always check both)

  4. Assuming manufactured homes are allowed everywhere (they’re not)

  5. Zoning changes mid-deal (yes, it happens)

My Real-World Advice

Before you do anything with a property, find the zoning code and dig deeper. Don’t just take the seller’s word for it. And if a listing says “buyer to verify,” that’s your cue to do the homework.

Better yet, let someone like me help you break it down.

I do this every day for landowners who inherited land, bought at auction, or just want to know what they’re working with.
