Phoenix Rent Increase Rules 2026–27: No Rent Control, the 30-Day Month-to-Month Rule, Retaliation Limits and the Rental Tax Repeal
If your Phoenix landlord just told you the rent is going up, your first question is probably whether they're allowed to raise it that much. In Arizona, the short answer is usually yes. State law bars cities from capping rents, so there's no Phoenix equivalent of the rent limits you hear about in Los Angeles or Seattle.
That doesn't mean anything goes. Your lease, the type of tenancy you have, and a few state laws all limit when and why rent can go up. This guide walks through the rules in Arizona's Residential Landlord and Tenant Act that matter most when you get a rent increase notice.
Last checked October 2026. Sources: Arizona Revised Statutes (A.R.S.) on azleg.gov, an Arizona Senate fact sheet, the Arizona Department of Revenue (ADOR), and Community Legal Services. This is general information, not legal advice.
The Short Version
No rent control: Arizona preempts it. Phoenix can't cap how much your rent goes up (A.R.S. 33-1329).
Fixed-term lease: rent is whatever your lease says for the length of the lease. A mid-lease increase generally needs a lease term that allows it.
Month-to-month: either side can end the tenancy with 30 days' written notice before the rent date. The statutes we reviewed don't set a separate rent-increase notice period.
Retaliation is illegal: a landlord can't raise rent because you complained about code violations or repairs, or joined a tenants' union (A.R.S. 33-1381).
Rental tax repeal: since January 1, 2025, cities can't tax long-term residential rent, and landlords had to stop charging tenants that tax.
New utility billing: for existing tenants, a landlord must give 90 days' notice before starting submetering or ratio utility billing.

Why Phoenix Can't Cap Your Rent
Arizona law is direct on this. A.R.S. 33-1329 says the Legislature treats rent control on private residential housing as a matter of statewide concern, and that "the power to control rents on private residential property is preempted by the state." Cities, including charter cities like Phoenix, and towns "shall not have the power to control rents."
So there's no percentage limit, no annual cap, and no rent board to appeal to. A landlord can raise rent by any amount, as long as the increase follows your lease and the timing rules below.
The exception: the preemption doesn't apply to residential property that is owned, financed, insured or subsidized by a state agency, a city or a town. If you live in public housing or a building with government financing or subsidies, the program's own rules may limit increases. Ask your property manager or housing authority which rules apply to your unit.

If You Have a Fixed-Term Lease
Under A.R.S. 33-1314(A), a landlord and tenant can put terms in a rental agreement covering rent, the length of the lease and the rights of each side, as long as the terms aren't prohibited by law.
In practice, that means the rent in a signed 12-month lease is the rent for those 12 months. Before you assume an increase is allowed, read your lease for clauses like:
an escalation clause that raises rent on a set date;
a clause letting the landlord add new fees or utility charges; or
renewal terms that say what happens when the lease ends.
If nothing in your lease allows a mid-term increase, a notice that tries to raise rent in the middle of your lease is worth questioning. Ask the landlord in writing which lease clause they're relying on.
At renewal time, things change. When a lease ends, a landlord can offer a new lease at a higher rent. You can accept, try to negotiate, or move out.
If You're Month-to-Month
If your lease has no fixed end date, A.R.S. 33-1314(D) says the tenancy is month-to-month, unless you're a roomer paying weekly.
A.R.S. 33-1375(B) lets either side end a month-to-month tenancy with written notice at least 30 days before the periodic rental date named in the notice. A week-to-week tenancy needs 10 days' written notice.
What this means for rent increases: the Arizona statutes we reviewed don't set a specific notice period for raising rent. Because a landlord can end a month-to-month tenancy with 30 days' written notice, increases on month-to-month tenancies are commonly given with at least that much notice. If you get a shorter notice, or a verbal one, talk to a legal aid lawyer about whether it's effective.
Check the dates. The 30 days run to the periodic rental date, the day rent is due. A notice given on the 15th generally can't take effect on the 1st of the next month.
When a Rent Increase Is Retaliation
Arizona doesn't limit the size of increases, but it does limit the reason. Under A.R.S. 33-1381, a landlord may not retaliate by increasing rent, decreasing services, or bringing or threatening an eviction after a tenant has:
complained to a government agency about a building or housing code violation that materially affects health and safety;
complained to the landlord about a violation of the landlord's maintenance duties under A.R.S. 33-1324; or
organized or joined a tenants' union or similar group.
The six-month presumption
This is the part most tenants don't know. If you made a protected complaint within six months before the rent increase, the law creates a presumption that the increase was retaliation. The landlord then has to produce evidence that it wasn't.
The presumption doesn't apply if you complained after you'd already received a notice of termination.
Limits on the protection
A landlord can still file an eviction if:
the code violation was caused mainly by a lack of reasonable care by you, someone in your household, or a guest; or
you're behind on rent.
Tip: if you've asked for repairs, keep copies of your requests, any city complaint numbers, and the date of every notice you get. Dates matter for the six-month window.
The Rental Tax Repeal: Make Sure It Came Off Your Bill
Until the end of 2024, Phoenix and many other Arizona cities charged a transaction privilege tax (TPT) on residential rent, and landlords often passed it to tenants as a line item.
According to ADOR, starting January 1, 2025, cities can no longer levy that tax on long-term residential rentals of 30 days or more. ADOR says there's no state or county tax on residential rentals either.
The Arizona Senate's fact sheet on the law, S.B. 1131, describes two protections for tenants:
landlords had to stop charging tenants the amount of the repealed rental tax by January 1, 2025; and
in a lawsuit challenging a charge, the landlord has the burden of proving the charge isn't the repealed tax.
The fact sheet also says the rent-reduction requirement is repealed on January 1, 2027. That date is coming up, so if you think you're still paying the old tax, raise it now.
What to do: compare a 2024 rent statement with a current one. If a "rental tax" or "city tax" line is still there, or the rent didn't drop and the tax just disappeared into the base rent, ask your landlord in writing to explain. If you can't resolve it, contact legal aid.
Utility Charges and Fees
Rent increases sometimes show up as new utility charges instead. A.R.S. 33-1314.01 sets rules for landlords who bill separately for gas, water, wastewater, trash or electricity:
The landlord can recover the provider's charges plus an administrative fee for actual costs only. No other charges are allowed.
The lease must list the utilities billed separately and the amount of any administrative fee.
For existing tenants, the landlord must give at least 90 days' notice before starting submetering or ratio utility billing. Starting it during a lease also requires that the lease allow it.
Bills must show the charges for the period, meter readings and dates if submetered, and any administrative fee.
If you disagree with a utility bill, the law says you must first object in writing to the landlord. If that doesn't resolve it, you can file a civil complaint in justice court.
Don't Withhold Rent Over an Increase
A.R.S. 33-1368(B) says a tenant may not withhold rent for any reason the landlord-tenant law doesn't authorize. If you refuse to pay a rent increase you think is improper, you risk a five-day notice for nonpayment and an eviction case.
A safer approach:
Ask the landlord in writing to explain the increase and the lease clause behind it.
Keep paying the amount you're sure you owe while you get advice.
Call legal aid before the new rent takes effect.
