Moved Here Full-Time? Make Sure Your Home Is Classified as Your Primary Residence

Many people first buy here as a winter home. They come for a few months, fall in love with Arizona, and a few years later they decide to make it home full-time.

It’s a wonderful decision. But there’s one small step that’s easy to miss along the way: letting the Maricopa County Assessor know that your home is now your primary residence.

I’m Monica Condomitti, a Luxury Real Estate Advisor with MC Luxury Real Estate at Coldwell Banker, serving Rio Verde and North Scottsdale, Arizona. I see this situation often, so here’s what to know. This is general information, not tax advice.

Why the Classification Matters

Every property in Maricopa County has a “legal class.” A home you live in as your primary residence is Class 3. A vacation or second home that isn’t rented out is usually Class 4.

The classification matters because a primary residence can qualify for a state credit on the school portion of your property taxes. Under Arizona law, that reduction can be up to $600 a year for a primary residence (A.R.S. § 15-972). A second home doesn’t qualify.

So if you’ve moved here full-time but your home is still classified as a second home, you may be paying more than you need to.

What Counts as a Primary Residence?

According to the Maricopa County Assessor, a primary residence is your one and only main residence, where you live more than seven months of the year. You can have only one primary residence, no matter how many homes you own, in Arizona or anywhere else.

How to Check Your Home’s Classification

You can look up your property on the Maricopa County Assessor’s website and see its current legal class. If your home shows as a second home or rental and you now live here full-time, it’s worth asking about a change.

How to Request a Change

The Assessor has a form called the Request for Residential Legal Class Change. You’ll need to show proof that the home is your primary residence, such as:

• an Arizona driver’s license showing the property address
• a voter registration card showing the property address
• the name-and-address section of your tax return, along with a vehicle registration or utility bill

The Assessor’s legal class page has the current form and instructions, and their office can answer questions at 602-506-3406.

Timing Matters

According to the Assessor, changes filed and approved before July 1, 2026 apply to the 2026 and 2027 tax years. Changes filed and approved after July 1, 2026 apply to the 2027 tax year. If an earlier year may have been classified incorrectly, the Assessor describes a separate process called a Notice of Claim that can correct up to three prior years.

Because dates and rules can change each year, check the Assessor’s site for the current deadlines.

It Works the Other Way, Too

If you move away and keep your Arizona home as a second home, or start renting it out, the classification should change as well. The Assessor reviews classifications and may mail a notice asking you to confirm how the home is used. If a notice arrives, respond to it, because not responding can lead to the home being reclassified.

Easy to Miss, Easy to Fix

If this applies to you, you haven’t done anything wrong. Life changes, and this is simply one of those details that’s easy to overlook when you’re busy settling into your new life here.

The best next step is to check your classification on the Assessor’s site and ask your tax professional how a change would affect you.

Frequently Asked Questions

How do I change my home to my primary residence in Maricopa County?

Submit the Maricopa County Assessor’s Request for Residential Legal Class Change, with proof that you live in the home, such as an Arizona driver’s license or voter registration showing the property address.

What is Class 3 property in Arizona?

Class 3 is the legal class for a home used as a primary residence. In Maricopa County, a primary residence is your one main residence, where you live more than seven months of the year.

No. Only one home can be your primary residence. A second or vacation home is usually classified differently and doesn’t qualify for the primary residence credit.

A rental is classified differently from a primary residence, and the classification should be updated. Check with the Assessor and your tax professional about what applies to you.
