Is a late fee legal? State caps, worked examples

Key Takeaways

• A $75 late fee on $1,650 monthly rent in New York exceeds the state cap. New York limits late fees to the lesser of $50 or 5% of rent, and 5% of $1,650 is $82.50, so the lower figure, $50, is the actual legal ceiling, not the percentage.

• The same $1,650 rent in North Carolina allows a higher fee: North Carolina caps late fees at the greater of $15 or 5% of rent, so 5% ($82.50) governs, and a $75 fee is legal there.

• Identical rent, identical late fee amount, opposite legal outcomes, because the two states use opposite comparison logic: New York takes the lesser of the two figures, North Carolina takes the greater.

• A late fee that exceeds a state's statutory cap is generally unenforceable in court even if the signed lease states the higher amount. The lease cannot override the statutory ceiling.

• Several states use a "reasonable" standard rather than a fixed cap, and courts in those states have generally treated fees above 10% of rent as carrying real legal risk, even without a specific statutory number to point to.

A $75 late fee looks identical on two different leases: one for a unit renting at $1,650 in New York, one for the same rent in North Carolina. One of those fees is legal. One of them isn't. The dollar amount alone never answers the question, because the same fee has to be checked against two entirely different formulas depending on which state the property sits in.

Numetix takes an expert-led, AI-powered, and human-in-the-loop approach to lease compliance review, checking each property's late fee structure against the current cap for its specific state rather than applying a single company-wide policy. This guide works through the exact math for two states with clearly documented, opposite-logic caps.

Quick Answer: Is a $75 late fee legal on $1,650 rent?

• It depends entirely on the state. In a state that caps fees at the lesser of a flat dollar amount and a percentage (New York's structure: lesser of $50 or 5%), $75 exceeds the cap and is not enforceable. In a state that caps at the greater of the two figures (North Carolina's structure), $75 is within the legal range.

• 5% of $1,650 rent is $82.50. Whether $75 is legal depends on whether the state's formula compares against the flat dollar figure, the percentage figure, or both, and whether it takes the higher or lower of the two.

• A fee that exceeds the applicable state cap is generally void as written in the lease, regardless of what the tenant signed, since a lease provision cannot legally exceed a statutory ceiling.

Why the same dollar figure can be legal in one state and not another

Late fee caps generally take one of three forms: a flat percentage of rent, a flat dollar amount, or a dollar-or-percentage formula that specifies whether the lesser or the greater figure applies. The third category is where identical numbers produce opposite outcomes, because "lesser of $50 or 5%" and "greater of $15 or 5%" are structurally different formulas even when they share the same percentage figure.

Worked example: New York, $1,650 rent, lesser-of formula

New York's late fee cap is commonly reported as the lesser of $50 or 5% of monthly rent. Calculating 5% of $1,650 gives $82.50. Comparing the two figures, $50 is lower than $82.50, so $50 is the enforceable maximum, regardless of what the percentage calculation produced. A $75 fee exceeds this $50 ceiling and would not be enforceable, even though $75 is well under the $82.50 percentage figure, because the percentage figure was never the operative cap once the flat dollar amount came in lower.

Worked example: North Carolina, $1,650 rent, greater-of formula

North Carolina's late fee cap is commonly reported as the greater of $15 or 5% of monthly rent. The same 5% calculation gives $82.50, and comparing the two figures, $82.50 is greater than $15, so $82.50 becomes the enforceable maximum. A $75 fee falls within this ceiling and is legal in North Carolina under the same rent and the same dollar fee that would be void in New York.

The general 5% benchmark, and why it isn't a safe universal answer

Across states without a specific dollar-or-percentage formula, 5% of monthly rent is the figure most consistently cited as a defensible late fee, whether as an explicit statutory cap or as the level courts have generally treated as reasonable under a "reasonable fee" standard. Some states permit meaningfully higher fees (a small number allow fees in the 8 to 12% range), and a small number cap fees at a low flat dollar figure regardless of rent size. Treating 5% as a universal safe number will under-collect in the states that permit more and risk unenforceability in the states that permit less, which is why the specific state's formula, not a general industry benchmark, is what actually governs a specific lease.

Frequently asked questions

Can a landlord charge a late fee that isn't written in the lease?

Generally no. In nearly every state, a late fee must be disclosed in the signed lease, including both the amount and the trigger (how many days late before it applies), to be enforceable at all. A late fee charged that was never specified in the lease is typically unenforceable regardless of whether it falls within the state's statutory cap, since the disclosure requirement and the amount cap are two separate conditions that both have to be satisfied.

What happens if a PM company charges a late fee above the legal cap?

The excess portion is typically unenforceable, and depending on the state, charging an unlawful fee can expose the landlord to additional consequences beyond simply losing the excess amount, including potential statutory damages in a tenant dispute. Practically, if this is discovered, the correct response is to stop charging the excessive fee going forward and, depending on the state and the specific facts, potentially refund amounts already collected in excess of the cap, ideally with guidance from a PM-specialized accountant or attorney rather than a unilateral internal decision.

Do late fee caps apply to commercial leases the same way as residential?

Generally no. Most state statutory late fee caps are specific to residential tenancies; commercial leases are typically governed by whatever the negotiated lease terms specify, with courts applying a general reasonableness standard rather than a specific statutory percentage or dollar cap. This is one of several areas where commercial and residential property management accounting diverge meaningfully, covered in more detail in the commercial vs residential accounting guide.
