Move-in fee vs security deposit: the accounting and legal difference

Key Takeaways

• A move-in fee is a non-refundable charge the PM company keeps to cover prep or repair costs. A security deposit is refundable money held in trust and returned if the tenant meets the lease terms. They are not two names for the same money.

• A clearly labeled non-refundable fee for a service is earned revenue the day it's received. A refundable deposit is not revenue at all; it's a trust liability the entire time it's held, since it legally remains the tenant's money.

• Most states don't cap non-refundable move-in fees, but real exceptions exist: Arizona requires the fee's purpose in writing, Chicago layers additional rules through its Residential Landlord and Tenant Ordinance, and Massachusetts bars application fees entirely.

• Whether interest is owed on a held deposit varies by state and, in several states, by threshold conditions like building size or deposit amount. Sources disagree on the exact count of states requiring interest, which is itself a reason to confirm the specific state's current rule rather than relying on a general figure.

• Skipping required deposit interest or commingling deposit funds with operating funds can trigger statutory penalties on its own, entirely independent of any dispute over deductions at move-out.

A tenant hands over two payments at move-in. Same bank, same signature, maybe even the same dollar amount. One of them is money the PM company can spend that night. The other one isn't the PM company's money at all; it stays the tenant's the entire time it sits in the account.

Quick Answer: What's the difference between a move-in fee and a security deposit?

• A move-in fee is a non-refundable charge the landlord keeps to cover prep or repair costs. A security deposit is refundable money the landlord holds and returns if the lease terms are met.

• The fee is earned revenue from the day it's received; the deposit is a trust liability the entire time it's held, since it legally remains the tenant's property until any lawful deduction is applied at move-out.

• Legal treatment varies by state: most states don't cap a non-refundable move-in fee, but several, including Arizona, require the fee's purpose stated in writing, and some cities layer on additional local rules.

A move-in fee and a security deposit are not the same kind of money

The whole distinction comes down to one question: whose money is it while it's being held? A move-in fee is a non-refundable charge added to cover repair or preparation costs incurred before move-in. A security deposit is refundable: it's held, and returned if the lease terms are met. One is a payment. The other is money held in trust.

This distinction matters because it follows the money into two different systems: the PM company's own books and the state's landlord-tenant statute. Get the label wrong and both can create real problems, which is why the label needs to be deliberate, not incidental.

A move-in fee is earned revenue on receipt; a refundable deposit is not

The accounting split turns on whether the money actually belongs to the PM company yet. A non-refundable fee, clearly labeled as a charge for a specific service, a cleaning fee or a pet fee, for example, functions as earned revenue from the moment it's received. A refundable deposit does not; it's excluded from revenue at receipt because it may need to be returned at the end of the lease.

Think of it like a coat check. When someone hands over their coat and a token, no payment has occurred; the coat check is holding property it's obligated to return. A tip left on top, by contrast, is earned the moment it's handed over. The move-in fee is the tip. The deposit is the coat.

Whether a move-in fee is even legal depends on the state and city

The legal picture is genuinely a patchwork. Most states don't cap the amount that can be charged for a non-refundable move-in fee or control what it can be used for; as a market observation, a move-in fee commonly runs about 20% to 50% of one month's rent. Then the exceptions start. Under Arizona Revised Statutes §33-1321, the purpose of every nonrefundable fee must be stated in writing, and any fee not specifically designated as nonrefundable is deemed refundable by default. Arizona also caps security deposits, however denominated, at one and one-half months' rent. In Illinois, move-in fees are legal but subject to further local regulation, particularly Chicago's Residential Landlord and Tenant Ordinance. Massachusetts doesn't permit landlords to charge application fees at all. Virginia allows a refundable application deposit alongside a separate nonrefundable application fee. "Legal in most states" is not the same as "legal where a specific property sits"; confirm both the state and the city before finalizing a fee structure.

Where the real risk sits: interest and commingling, not the deduction fight

The sharpest compliance risk isn't the deduction dispute at move-out; it's the interest and commingling rules that sit underneath the deposit itself. In several states, deposits must be held in interest-bearing accounts with the interest paid to the tenant, and both the obligation and the specific rate vary by state and, sometimes, local ordinance. Commingling deposit funds with operating funds, or simply skipping required interest, can trigger statutory penalties entirely on its own, independent of whether any deduction dispute ever arises.

Many of these interest rules are conditional, triggered only once a specific threshold is met: building size, deposit dollar amount, or length of holding period. Threshold states include New York and Illinois for larger buildings, and several other states apply thresholds tied to holding period or deposit size specifically. One important caution: published counts of exactly how many states require interest, and the specific rates, conflict across sources. Confirm the current, primary-source figure for the specific state before publishing or relying on any number, rather than treating a secondary source's count as settled.

Four things to fix before the next tenant signs

• Label every charge in writing: mark the fee "nonrefundable" explicitly in the lease so it can't later be claimed as a refundable deposit. In Arizona specifically, anything not marked nonrefundable is deemed refundable by default.

• Confirm state and local fee rules: most states don't cap the fee amount, but city-level ordinances, like Chicago's RLTO, add layers state law alone doesn't cover.

• Record fees as revenue and deposits as a liability: a fee labeled for a specific service is earned revenue at receipt; a refundable deposit is money owed back and belongs on the books as a liability, not revenue, until any lawful deduction is actually applied.

• Check whether deposit interest is owed: confirm the specific state's current interest requirement and threshold conditions before assuming either that interest applies or that it doesn't.

Frequently asked questions

Can a PM company charge both a move-in fee and a security deposit on the same lease?

Generally yes, in most states, since they serve different purposes and carry different legal treatment. Confirm the specific state doesn't restrict combining the two; a small number of jurisdictions cap the combined total of all deposit-like charges, which can affect how much room remains for a separate move-in fee once the security deposit is set.

Does a pet fee follow the same rules as a general move-in fee?

The same underlying logic applies, refundable versus non-refundable determines the accounting treatment, but pet-related charges increasingly have their own specific state rules layered on top of general move-in fee rules. Confirm whether the state treats pet fees, pet deposits, and pet rent as distinct categories with separate requirements, since several states now regulate this specific area more tightly than general move-in fees.

What happens if a fee is collected as "nonrefundable" but the state doesn't recognize that structure?

If a specific state doesn't permit a charge to be structured as nonrefundable for the purpose collected, for example some application-fee frameworks, the label in the lease doesn't override the state's actual legal requirement. The charge may be treated as a refundable deposit regardless of how it was labeled, which means the underlying accounting treatment should follow the state's actual rule, not just the lease's stated intent, whenever the two conflict.
