Work out the fee, then check it against what A.R.S. § 33-1368(B) actually allows. No sign-up, and the arithmetic is shown so you can put it on the notice.
Many states and cities cap late fees, require a minimum grace period, or require the fee to be stated in the lease. Check your local rules and your lease before charging.
Flat fee of $50.00 once the grace period passes.

No statutory cap — the fee must be “reasonable”
No statutory grace period
Yes — the fee must be set out in a written rental agreement
A.R.S. § 33-1368(B)
This is the most common error in Arizona late-fee content. The five-day period in § 33-1368(B) runs after the landlord serves written notice of nonpayment and intent to terminate — it is the tenant’s window to cure before termination. It is not a waiting period before a late fee may be charged. Rent is unpaid when due, and any grace period has to come from the lease itself.
Arizona requires a “reasonable late fee set forth in a written rental agreement” and stops there. There is no statutory flat-dollar or percentage limit, and “reasonable” is not defined in the statute.
The statute conditions the fee on being set forth in a written rental agreement. An oral understanding or a mid-tenancy announcement does not meet that.
Under § 33-1368(G) the periods in this section are counted in calendar days, so weekends and holidays are included unless the lease says otherwise.
A.R.S. § 33-1329 bars cities and towns from controlling rents on private residential property. That provision is about rents, not fees, so it is not a blanket statement that no local rule can ever touch late fees — check your city if you are near a cap.

Rentwelly applies late fees by rule and posts them to the ledger, so the tenant balance is right and the income lands in the right period.
No statutory cap — the fee must be “reasonable”. The rule is in A.R.S. § 33-1368(B). A lease cannot authorise more than the statute allows, so where there is a ceiling it governs whatever the lease says.
No. Arizona sets no statutory grace period, so the timing comes from the lease — which makes it important that the lease states it clearly.
Yes — the fee must be set out in a written rental agreement. As a practical matter, a fee that is not written into the lease is difficult to collect anywhere, however reasonable the amount.
Arizona’s five days is a notice period, not a grace period. This is the most common error in Arizona late-fee content. The five-day period in § 33-1368(B) runs after the landlord serves written notice of nonpayment and intent to terminate — it is the tenant’s window to cure before termination. It is not a waiting period before a late fee may be charged. Rent is unpaid when due, and any grace period has to come from the lease itself.
Yes, a late fee you actually collect is rental income. The cleaner practice is to post the charge when it is applied and the payment when it arrives, so the tenant balance and your books agree rather than drifting apart.
