Maryland Late Fee Laws: The Landlord and Tenant Guide

Maryland is refreshingly clear where many states are vague: it caps a residential late fee with a hard number. Under the Maryland Code, Real Property, section 8-208(d)(3), a late fee may not exceed five percent of the rent due for the rental period for which the payment was delinquent, and a lease that tries to charge more is unenforceable to that extent. That single ceiling — five percent, with a separate flat limit for weekly tenancies — drives everything on this page. There is no statewide grace period baked into that rule, but Baltimore City, Montgomery County, and Prince George’s County each add one, and a late fee has its own distinct place in Maryland’s failure-to-pay-rent eviction process.

This guide walks the full framework in plain English: exactly what the five percent cap limits and how it is measured, the special three-dollar-a-week and twelve-dollar-a-month rule for weekly rentals, whether any grace period exists and which counties add one, when a fee may first be charged and why it must be in the written lease, the separate dishonored-check rule under Commercial Law section 15-802, and the critical point that a late fee is not rent for a failure-to-pay-rent action under section 8-401. It also covers the special cases — mobile-home parks and subsidized housing — local ordinances, how a tenant contests an unlawful fee, a practical playbook for both sides, real scenarios, and a Maryland-specific FAQ.

Because Maryland fixes the ceiling by statute, the safest posture for a landlord is a fee at or below five percent, written into the lease, that respects the local grace period; the strongest position for a tenant is to know that any fee above the cap, or absent from the lease, is unenforceable. Treat every figure here as a starting point and verify the current statute and any local ordinance before you charge, pay, or dispute a fee.

Before diving into the mechanics, it helps to see exactly what Maryland law does and does not control. A late fee is not rent. It is a contractual charge the landlord adds when rent arrives late, and Maryland does something many states avoid: it puts a firm statutory ceiling on that charge. The controlling provision is Maryland Code, Real Property, section 8-208(d)(3), which bars a lease from providing for a late-payment penalty in excess of five percent of the rent due for the rental period the payment was late.

So the narrow legal question in Maryland is not the open-ended “is this fee reasonable?” that some states ask. It is far more concrete: is the fee written into the lease, and is it at or below five percent of the delinquent rent? If yes on both counts, the fee is generally enforceable. If the fee exceeds five percent, the excess is unenforceable, because a provision that violates section 8-208 cannot be enforced by the landlord. Everything else on this page — grace periods, the weekly rule, the eviction interplay — orbits that single ceiling.

This makes Maryland easier to comply with than a reasonableness state, but the number still has to be applied correctly. Five percent is measured against the rent for the period that was late, not against the whole year or some larger base, and the weekly-tenancy rule swaps in a flat-dollar limit instead of the percentage. Getting the base wrong, or importing a monthly-style fee onto a weekly tenant, is the most common way a Maryland late fee slips over the line.

At the state level, the answer is no. Real Property section 8-208 sets the five percent ceiling on the amount of a late fee, but it does not, by itself, require a landlord to wait a fixed number of days after the due date before the fee attaches. In other words, the statute governs how much a late fee can be, not when it may begin. Any waiting period a tenant enjoys therefore comes from the written lease or from a local ordinance, not from the statewide statute.

This surprises people who assume every state guarantees a few free days. Under the state rule alone, if the lease says rent is due on the first and grants no cushion, a late fee can attach once the rent is late, subject only to the five percent cap. But three of Maryland’s largest jurisdictions have added grace periods by local law, and for a great many Maryland tenants those local rules are what actually control the timing.

The County and City Grace Periods

Three jurisdictions each require a waiting period the state statute does not. Baltimore City requires residential leases to bar a late fee unless the rent is more than ten days late, and then charge no more than one percent of the monthly rent per day beginning on the eleventh day, up to a total of five percent of the monthly rent. Montgomery County prohibits a landlord from charging a late fee unless the rent is more than ten days late, and even then the fee may not exceed five percent of the monthly rent. And Prince George’s County gives a five-day grace period, allowing a late fee only beginning on the sixth day of the rental period, and charging no more than one percent of the monthly rent per day up to the five percent ceiling; it also has a public-assistance timing rule that pushes the fee later when an assistance check was mailed late. In each of these places, the landlord must clear the local waiting period first and still keep the fee within five percent.

This is the heart of Maryland late-fee law. Under Real Property section 8-208(d)(3), a lease may not provide for a penalty for the late payment of rent in excess of five percent of the amount of rent due for the rental period for which the payment was delinquent. The measure is precise: take the rent for the period that was paid late, multiply by five percent, and that is the ceiling. On monthly rent of one thousand dollars, the maximum late fee is fifty dollars for that month; on one thousand five hundred dollars, it is seventy-five dollars. A landlord may charge less, but never more.

Because the cap is tied to the rent for the delinquent period, it is not a running or compounding figure. A landlord cannot add five percent again and again for each day or week the rent stays unpaid within the same period, and cannot base the five percent on a larger sum such as annual rent. The fee is a one-time charge measured against that period’s rent. A provision that tries to charge more — a flat penalty above the cap, a daily fee that adds up past five percent, or a percentage of the wrong base — is unenforceable by the landlord to the extent it exceeds the statute.

The Weekly-Tenancy Rule

Maryland carves out weekly tenancies from the percentage rule. Where rent is paid in weekly installments, the late penalty may not exceed three dollars for any one week or a total of twelve dollars in any one month, under the same section 8-208(d)(3). This is a flat-dollar cap, not a percentage, and it exists because five percent of a single weekly installment would be a very small and awkward figure. A landlord who charges a weekly tenant a monthly-style late fee, or five percent of a weekly installment, is charging more than the weekly rule allows, and the excess cannot be enforced.

A late fee cannot appear out of thin air. To be enforceable at all, the fee must be provided for in the written rental agreement. The lease has to say a late fee applies, when it applies, and how much it is — and that amount cannot exceed five percent of the delinquent rent, or the weekly flat caps. A landlord cannot add a late fee the lease never mentions, cannot spring one on the tenant mid-tenancy without a proper new agreement, and cannot charge more than both the lease and the statute allow. If the lease is silent on late fees, there is simply no late fee to collect.

Assuming the lease does provide for a fee, timing follows the due date and any applicable grace period. Under the state rule alone the fee may attach once the rent is late, but inside Baltimore City, Montgomery County, or Prince George’s County the local grace period sets the earliest date the fee can begin. Writing the fee into the lease is only the first hurdle: the clause opens the door, and the five percent ceiling then decides how large the fee may be. A lease that authorizes a fee above the cap does not make that amount valid — it just creates a clause that is unenforceable for the part above five percent.

A bounced rent check is governed by its own statute, separate from the late-fee cap. Under Maryland Code, Commercial Law, section 15-802, when a tenant’s check is dishonored, the landlord (as holder) may send the tenant a written notice of dishonor. If the check is still unpaid thirty days after that notice is sent, the drawer becomes liable for the amount of the check, a collection fee of up to thirty-five dollars, and additional damages of up to two times the amount of the check, but not more than one thousand dollars. The landlord may then seek those damages in the District Court of Maryland.

Two points matter here. First, the remedy is procedural: it is unlocked only by mailing the statutory notice of dishonor and then waiting the thirty days, not by the bounce alone. Second, the dishonored-check remedy is entirely separate from the five percent late fee. A returned rent check can trigger both — a late fee because the rent is now late, and the section 15-802 damages because the check bounced — but they rest on different statutes and different caps, and each must be justified on its own terms.

This is where the late fee meets the eviction process, and Maryland draws a clean line. A landlord who wants to evict for nonpayment brings a failure-to-pay-rent action under Real Property section 8-401. For that purpose, a late fee is not rent: rent means the periodic charge for the use or occupancy of the premises, not the other amounts a tenant may owe, even if the lease labels them additional rent. The case is therefore built on the unpaid rent itself, and unpaid late fees cannot by themselves drive a nonpayment eviction.

Since October 1, 2024, the Renters’ Rights and Stabilization Act also requires the landlord to serve a written ten-day Notice of Intent to File before filing the failure-to-pay-rent complaint, using the official court form, telling the tenant how much rent is overdue and giving ten days to pay. That notice and the action turn on the rent, and our Maryland eviction notice laws guide covers the process in depth. A late fee may still appear later in the case — a court can award late fees and court costs on top of the rent — but the fee is not the engine of the eviction.

The tenant’s right of redemption ties this together. If the landlord wins a judgment for possession, the tenant can stop the eviction by tendering, at any time before the eviction is actually carried out, all past-due amounts as determined by the court, plus court-awarded costs and fees — which can include the awarded late fees. So a valid late fee is collectible within the case as part of what the court awards and what the tenant must tender to redeem, but it is not a stand-alone basis to remove the tenant. A landlord who wants to pursue a disputed late fee outside the rent case can treat it as an ordinary contract debt, for example in small claims, or, at move-out, deduct a valid late fee from the deposit where the lease allows — a step governed by the Maryland security deposit laws.

The five percent cap is the baseline for ordinary residential rent, but several categories of housing carry their own layered rules, and the plain percentage analysis is not the whole story for them.

Mobile-Home and Manufactured-Home Parks

Manufactured-home and mobile-home park tenancies operate under their own Maryland framework rather than the ordinary apartment analysis alone. Park rules, community documents, and the terms governing lot rent can shape when and how a late fee applies, so a park cannot simply import an apartment-style penalty without regard to those rules. A park homeowner facing a late fee should read the community’s governing documents alongside the state cap, and a park operator should confirm the fee fits both the park framework and the five percent ceiling before charging it.

Subsidized Housing (Section 8 and Similar)

In the Housing Choice Voucher program and similar subsidized tenancies, a late fee generally applies only to the tenant’s own share of the rent, not to the portion the housing authority pays, and the program contract or lease rider may cap or bar the fee entirely. A landlord who accepts a voucher agrees to the program’s terms for the contract term, so the program rules ride on top of state law. Prince George’s County goes further for certain public-assistance recipients, delaying the late fee when an assistance check was not mailed on time. The five percent cap still applies, but within the narrower band the program or local rule allows.

Maryland’s counties and Baltimore City can and do add their own rules on top of the state cap, and where a local ordinance is more protective of tenants, it controls. The clearest examples are the grace periods discussed above: Baltimore City bars a late fee unless the rent is more than ten days late, then limits it to one percent of the monthly rent per day from the eleventh day up to the five percent ceiling; Montgomery County prohibits a fee unless the rent is more than ten days late, and even then the fee may not exceed five percent of the monthly rent; and Prince George’s County allows a fee only from the sixth day of the rental period and limits it to one percent of the monthly rent per day up to the five percent ceiling. A fee that satisfies the state cap on amount can still violate one of these local timing rules.

Because coverage varies by jurisdiction, the only reliable step is to check the rule for the specific address. A landlord should confirm which county or municipality the property sits in and what that place says about when a late fee may begin and how it must be disclosed, before charging one. A tenant should check whether the local rules give more protection than the statewide five percent cap — in Baltimore City, Montgomery County, and Prince George’s County, they often do, at least on timing.

Because Maryland fixes the ceiling by statute, a tenant challenging a late fee has a clear yardstick: the fee must be in the lease and at or below five percent of the delinquent rent, or the weekly flat caps, and it must respect any local grace period. A provision that violates section 8-208 is unenforceable by the landlord, so a fee that tops the cap or is missing from the lease can be resisted with confidence.

The five percent cap rewards simple discipline on both sides. For landlords, a fee kept inside the ceiling and the local grace period holds up; for tenants, knowing the cap and the lease requirement keeps you from paying money you do not owe.
