Arizona Late Fee Laws: Rent, HOA, and Consumer Rules

Arizona late fee laws set different caps depending on what you owe and to whom. Residential rent late fees are limited to $5 per day after a five-day grace period. HOA assessment late fees are capped at the greater of $15 or 10% of the overdue amount, and only after 15 days. Small consumer loans and revolving accounts allow the lesser of $10 or 5% of the installment after 10 days. Commercial contracts have no fixed cap but must pass a reasonableness test. Credit cards follow federal law, not Arizona statute.

The context controls the number. A fee that is lawful on a vendor invoice would be void in a lease, and a fee a landlord tries to charge on day three is unenforceable no matter what the lease says.

Residential Rent Late Fees

If your rent is due on the first, you have through the fifth to pay with no penalty. Starting on the sixth day, a landlord can charge up to $5 for each day the rent remains unpaid, counted back to the original due date rather than from day six.¹

Two conditions have to be met before any fee is owed. The lease must authorize it in writing, and the agreement has to give the tenant at least five days after the due date to pay. A clause that charges earlier, or at a higher daily rate, is unenforceable.¹

If the Landlord Overcharges

A landlord who knowingly puts a prohibited late fee in the lease — a daily rate above $5, no grace period, or a fee the written lease never authorized — is exposed. The tenant can recover actual damages and can void the entire rental agreement.¹

Curing a Late Payment Before Eviction

When rent goes unpaid, the landlord has to deliver a written notice giving the tenant five days to pay before filing. If the tenant pays everything owed, including any reasonable late fee the lease actually spells out, before the landlord files the eviction action, the lease is reinstated by operation of law.²

HOA Assessment Late Fees

Homeowners associations follow their own cap. The late fee on an unpaid assessment is limited to the greater of $15 or 10% of the amount owed, and it can only be imposed after the payment has been overdue for at least 15 days. Before the fee attaches, the HOA has to give notice that the assessment is past due or that it will become past due on a specific date. Community documents can lengthen the grace period, never shorten it.³

The same formula applies if the HOA tries to charge a late fee on an unpaid penalty: no more than the greater of $15 or 10%, and not until 15 days have passed.³

Consumer Loans and Revolving Accounts

For closed-end loans of $5,000 or less and for revolving accounts, a lender cannot charge a late fee until the installment is at least 10 days past due. The fee is capped at the lesser of $10 or 5% of the overdue installment. On a $150 installment, 5% is $7.50, so $7.50 is the ceiling; on a $50 installment, the cap is $2.50.⁴

This fee is on top of interest, not instead of it. The 10-day grace period is set by statute and cannot be shortened by the loan agreement.⁴

Consumer Services

Gym memberships, subscription plans, maintenance contracts, and similar ongoing services run on a different formula. A seller can impose a delinquency fee only when the unpaid balance is more than $10 and at least 15 days have passed since the invoice due date.

Balances of $25 or less: up to $5.
Balances over $25: up to $10 or 5% of the unpaid balance, whichever is greater.

The direction flips here. For loans, you take the lesser of $10 or 5%. For consumer services, you take the greater. On a $300 unpaid service balance, 5% is $15, which beats the $10 floor, so $15 is the cap.⁵

Credit Cards Are Federal, Not State

Credit card late fees do not fall under Arizona’s consumer loan statute. They are governed by federal Regulation Z, which requires any penalty fee to be reasonable and proportional to the violation and provides safe harbor dollar amounts presumed reasonable. Those amounts are $32 for a first late payment and $43 for a second late payment within six billing cycles of the first, adjusted annually for inflation.⁶

The CFPB issued a 2024 rule that would have cut the safe harbor to $8, but a federal court vacated that rule in April 2025, so the earlier amounts remain in effect. One hard limit always applies: a credit card late fee cannot exceed the minimum payment due. If the minimum is $25, the fee is capped at $25.

Commercial Contracts and the Liquidated Damages Test

Late fees in commercial leases, vendor agreements, construction contracts, and business-to-business invoices sit outside the specific statutes above. Enforceability is tested under Arizona common law on liquidated damages. The question a court asks is whether the fee is a genuine estimate of what late payment actually costs, or a penalty designed to coerce performance.

In Dobson Bay Club II DD, LLC v. La Sonrisa de Siena, LLC, the Arizona Supreme Court adopted the Restatement (Second) of Contracts framework. A late fee is enforceable only if the amount is reasonable in light of the anticipated or actual loss, taking into account how hard the real damages would be to prove. The two factors operate together: a larger fee is more defensible when actual damages would have been genuinely difficult to pin down when the contract was signed.⁷

In practice, a flat fee bearing no relationship to the contract value is vulnerable. A $500-per-day charge on a $2,000 agreement will likely be struck down as a penalty. A fee of 1.5% per month on an unpaid commercial invoice, where cash flow disruption is real but hard to quantify, generally holds up. If you are drafting the contract, the fee should track a realistic estimate of the cost of delay, and the agreement should say why that cost is difficult to measure precisely.

Servicemember Lease Terminations

Active-duty servicemembers who have to break a residential lease because of deployment or a permanent change of station get a specific federal shield. Under the Servicemembers Civil Relief Act, the landlord cannot impose any early termination charge on a qualifying servicemember. Rent and other obligations that accrued before the termination date are still owed. The lease ends 30 days after the next monthly rent payment is due following delivery of proper written notice.⁸

SCRA protections can be waived, but only knowingly and in writing. Read any waiver clause carefully before signing.

Recreational Vehicle Parks

RV parks sit under a separate statute, but the late fee math matches residential rentals: up to $5 per day beginning on the sixth day after the due date. The difference is that the fee is optional. The RV park rental agreement has to include it in writing. If the agreement is silent, no late fee can be charged at all.⁹

Late Fees and Credit Reports Are Not the Same

Whatever cap applies to the fee, a late payment does not land on your credit report the moment the fee attaches. Credit bureaus have no reporting code for payments one to 29 days late, so a payment that arrives a few days after the due date and triggers a fee will not necessarily show up on your credit history. Federal student loans have an even longer buffer and are not reported late until 90 days past due. The fee and the credit report hit run on separate timelines, and the first does not automatically produce the second.
