Maine Late Fee Laws: The Landlord and Tenant Guide

Four Percent Cap · 15-Day Grace Period · Written-Disclosure Rule · NSF Fees · Seven-Day Notice Interplay

Updated Q3 2026 By Tenant Screening Background Check Editorial Team Applies Maine ~15 min read

Maine is one of the most tenant-protective states in the country on late rent fees, and it does the exact opposite of a state like California: instead of an open-ended reasonableness test, Maine fixes two hard numbers. Under Maine Revised Statutes Title 14 section 6028, a residential late fee may not exceed four percent of one month’s rent, and a landlord may not charge any late fee until the rent is at least fifteen days late. On top of that, the fee only exists if the landlord disclosed it in writing when the tenant signed the lease. Those three rules — the four percent cap, the fifteen-day grace period, and the written-disclosure requirement — drive everything on this page.

This guide walks the full framework in plain English: what the law caps and by how much, why the fifteen-day grace period is unusually strong and cannot be shortened by the lease, when a fee may first be charged, the separate returned-check rule under Title 14 section 6071, and the critical point that an unpaid late fee cannot drive a seven-day notice to quit for nonpayment under Title 14 section 6002. It also covers the special cases — mobile-home parks under Title 10 section 9097-C, subsidized housing — local practice, how a tenant contests an unlawful fee, a practical playbook for both sides, real scenarios, and a Maine-specific FAQ.

Because Maine puts firm numbers in the statute, compliance is more mechanical here than in reasonableness states: a landlord who charges four percent or less, waits the full fifteen days, and disclosed the fee at lease signing is on solid ground, while a tenant who knows those three tests can spot an unlawful fee instantly. Treat every figure here as a starting point and verify the current statute before you charge, pay, or dispute a fee.

Maine Late Fees at a Glance

Statutory Cap

Four percent of one month’s rent

Grace Period

Fifteen days by statute

Governing Law

Title 14 section 6028

Disclosure

Written, at lease signing

Bottom line: Maine caps a residential late fee at four percent of one month’s rent and forbids charging it until the rent is fifteen days late, all under Maine Revised Statutes Title 14 section 6028. The landlord must have disclosed the possible penalty in writing when the lease was signed, or there is no enforceable fee at all. A bounced check is handled separately under Title 14 section 6071. And a late fee is not rent, so it cannot be the basis of a seven-day notice to quit for nonpayment under Title 14 section 6002. These are general rules; verify the current statute before you charge or dispute a fee.

Late Fees: The Narrow Legal Question

Before diving into the numbers, it helps to see exactly what Maine law controls. A late fee is not rent. It is a penalty the landlord may add when rent arrives late, and Maine treats that penalty as something the legislature has capped directly. Unlike states that ask an open-ended question about the landlord’s actual damages, Maine simply picks a number and a waiting period and writes them into the statute.

So the narrow legal question in Maine is not “was this fee a reasonable estimate of harm?” The real questions are mechanical: was the fee no more than four percent of one month’s rent, was it charged only after the rent was fifteen days late, and was the possibility of the fee disclosed in writing at the start of the tenancy? If all three are yes, the fee is generally valid. If any one is no, the fee is unlawful, no matter how the lease is worded.

This makes Maine one of the easier states to apply, and one of the friendlier to tenants. A landlord cannot argue up to a bigger fee by pointing to real costs, because the cap is fixed. A tenant does not have to litigate reasonableness, because the tests are numeric. Everything else on this page — the grace period, disclosure, the seven-day-notice interplay — orbits those three fixed questions.

Takeaway

Maine does not ask whether a late fee is reasonable — it fixes the answer. A fee is valid only if it is no more than four percent of one month’s rent, charged only after the rent is fifteen days late, and disclosed in writing at lease signing. Those three mechanical tests, under Title 14 section 6028, control every late fee in the state.

Is There a Statutory Grace Period?

Yes — and it is one of the strongest in the country. Under Maine Revised Statutes Title 14 section 6028, a payment of rent is not legally late until fifteen days have passed from the date the payment was due, and a landlord may not assess any late-payment penalty until the rent is at least fifteen days late. This is a statutory grace period, not a lease courtesy, so it exists whether or not the lease mentions it, and it applies to every ordinary residential tenancy in the state.

The practical effect is blunt. If rent is due on the first of the month, it is not “late” for penalty purposes on the second, the fifth, or the tenth. The earliest a lawful late fee can attach is the sixteenth, once fifteen full days have passed. A landlord who emails a tenant on the third demanding a late fee has jumped the gun, and that fee is unlawful because the fifteen-day clock has not run.

The Lease Cannot Shorten It

Because the fifteen-day grace period is written into the statute, a lease cannot cut it down. A clause that says “rent is late on the second and a fee applies immediately” is unenforceable to the extent it conflicts with Title 14 section 6028: the fee still cannot be charged until day fifteen has passed. A lease may be more generous — giving the tenant twenty days, say — but it can never be stricter than the statute. This is the reverse of a state like California, where any grace period comes only from the lease.

The fee cannot attach during the first fifteen days

The most common Maine late-fee error is charging the fee too early. A landlord who applies a penalty on day two, day five, or day ten has violated Title 14 section 6028, because the rent is not yet legally late. Wait the full fifteen days. A tenant who is charged a late fee inside that window should point to the statute and ask for it to be removed; the fee is not owed.

Takeaway

Maine gives tenants a statutory fifteen-day grace period under Title 14 section 6028 — rent is not legally late, and no fee may be charged, until fifteen days pass from the due date. The lease cannot shorten this window, only extend it. The earliest a lawful fee can attach is the sixteenth day.

The Four Percent Cap: Maine’s Anchor

This is the heart of Maine late-fee law. Under Maine Revised Statutes Title 14 section 6028, a landlord may not assess a penalty for the late payment of rent that exceeds four percent of the amount of rent due for one month. That is a hard ceiling. There is no reasonableness balancing, no argument that the landlord’s real costs were higher; four percent of a month’s rent is the maximum, full stop, and the landlord may always charge less.

The math is straightforward. If the monthly rent is one thousand dollars, four percent is forty dollars, and forty dollars is the most the landlord can charge for that late payment. If the rent is one thousand five hundred dollars, four percent is sixty dollars. A flat late fee written into the lease is fine only if, for that unit’s actual rent, it never works out to more than four percent of a month’s rent — so a fixed seventy-five-dollar fee on rent of one thousand dollars is unlawful, because seventy-five exceeds the forty-dollar ceiling.

The Cap Is Per Late Payment, Not Per Day

The four percent limit applies to the penalty for a given late payment; it is not four percent per day or four percent compounding each week the rent stays unpaid. A landlord cannot turn the cap into an escalating charge that grows the longer the rent is late. One late payment, one penalty, capped at four percent of a month’s rent. A structure that keeps adding four percent every few days quickly blows past the statutory ceiling and is unlawful.

Four percent is a ceiling, not a target

Nothing in Title 14 section 6028 requires a landlord to charge the full four percent. Many Maine landlords set a lower flat fee or a smaller percentage, both of which are lawful as long as they never exceed four percent of a month’s rent and are not charged before day fifteen. The statute sets the outer boundary; the landlord chooses anywhere at or below it. A modest fee is both lawful and less likely to sour the tenancy.

Fee designHow Maine treats it
Percentage at or below four percent of a month’s rentLawful — within the Title 14 section 6028 cap, provided it is charged only after day fifteen
Flat fee that never exceeds four percent for the unit’s rentLawful — a fixed figure is fine so long as it stays under the four percent ceiling for that rent
Flat fee above four percent of a month’s rentUnlawful — exceeds the statutory cap; only four percent is collectible at most
Escalating or per-day feeUnlawful — the cap is per late payment, not per day; a compounding charge blows past four percent

Takeaway

Under Title 14 section 6028, a Maine late fee may not exceed four percent of one month’s rent — a hard cap, not a reasonableness test. It is per late payment, not per day, so escalating charges are unlawful. Four percent is the ceiling; the landlord may always charge less, and a flat fee is fine only if it stays under that line.

When a Fee May Be Charged and the Written-Disclosure Requirement

A Maine late fee cannot appear out of thin air. To be enforceable at all, the possibility of the fee must have been disclosed to the tenant in writing at the time the rental agreement was made. Maine Revised Statutes Title 14 section 6028 says a landlord may not assess a late penalty unless the landlord gave the tenant written notice, when they entered into the lease, that a penalty of up to four percent of one month’s rent may be charged for late rent. The disclosure has to happen at the start; a landlord cannot spring a new late fee on a tenant mid-tenancy.

Assuming the disclosure was made, timing then follows the fifteen-day rule. The fee may attach only after the rent is fifteen days late — the sixteenth day at the earliest — and only up to the four percent cap. So the three requirements stack: written disclosure at signing, the fifteen-day wait, and the four percent ceiling. Miss the disclosure and there is no fee to collect; jump the fifteen days and the fee is premature; exceed four percent and the excess is uncollectible.

No written disclosure means no late fee

The written-disclosure requirement is a true gate. If the landlord never told the tenant in writing, at lease signing, that a late penalty of up to four percent could apply, then no late fee is enforceable — even if the rent is sixty days late and the amount would otherwise be within the cap. Landlords should build the disclosure into the lease itself; tenants should check whether the lease actually contains it before paying any late fee.

Takeaway

A Maine late fee is enforceable only if three things line up: the fee was disclosed in writing at lease signing, the rent is at least fifteen days late, and the amount is no more than four percent of a month’s rent. Miss any one under Title 14 section 6028 and the fee cannot be collected.

NSF and Returned-Check Fees

A bounced rent check is governed by its own statute, separate from the late-fee rule. Under Maine Revised Statutes Title 14 section 6071, the dishonored-check statute, when a tenant’s check is returned and the tenant does not pay after the required written demand, the holder may recover the amount of the check, court costs, the processing charges the holder incurred, and interest at twelve percent per year from the date the check was dishonored. A court may also award a civil penalty of up to one hundred fifty dollars in an appropriate case.

The statute has a sharper edge for repeat offenders. A second dishonored check to the same payee within one year can trigger enhanced liquidated damages — for a check that bounces for insufficient funds, up to twice the face amount of the check or four hundred dollars, whichever is less; for a check drawn on no account at all, up to twice the face amount or seven hundred fifty dollars, whichever is less. The drawer generally has a set number of days after a written demand to pay before those enhanced damages apply, which gives an honest tenant a chance to make the check good.

Keep the NSF remedy and the late fee distinct

A bounced rent check can trigger two different things: the rent is now unpaid, which starts the fifteen-day clock toward a possible four percent late fee under Title 14 section 6028, and the check itself is dishonored, which opens the returned-check remedy under Title 14 section 6071. They rest on different statutes with different figures. The twelve percent interest and the one-hundred-fifty-dollar civil penalty belong to the bad-check rule, not to ordinary late rent, so treat each on its own footing.

Takeaway

A bounced check is governed by Title 14 section 6071: the holder may recover the check amount, court costs, processing charges, and twelve percent yearly interest, with a civil penalty up to one hundred fifty dollars and enhanced damages for a repeat check within a year. This remedy is separate from any four percent late fee.

Can a Late Fee Lead to Eviction? The Seven-Day Notice Interplay

This is where late-fee mistakes can become eviction mistakes. A Maine landlord who wants to evict for nonpayment serves a seven-day notice to quit under Maine Revised Statutes Title 14 section 6002, and that notice may be served only once the tenant is at least seven days in arrears on rent. The notice is grounded in unpaid rent — and a late fee is not rent. Because the four percent penalty cannot even be charged until the rent is fifteen days late, a late fee has no place in the arrears figure that drives a seven-day notice.

There is a built-in escape hatch that protects tenants. Under Title 14 section 6002, if the tenant pays all rental arrears — all rent due as of the date of payment — plus any filing and service-of-process fees the landlord actually expended before the writ of possession issues, the tenancy is reinstated. The amount to cure is rent (and, once the case is filed, the landlord’s actual court filing and service costs), not a pile of late fees. A landlord who overstates the arrears by folding in a late fee muddies that cure figure and risks undermining the case.

That does not make a valid late fee uncollectible. It changes the collection path. A landlord may pursue a lawful four percent late fee as an ordinary contract debt — in small claims court, for example — separate from the eviction. What a landlord may not do is treat the late fee as rent, count it toward the seven-day arrears, or make paying it a condition of staying in the home when the statute lets the tenant cure by paying rent and the landlord’s actual filing and service costs. Our Maine eviction notice laws guide covers the seven-day notice in depth.

Never treat a late fee as rent in a seven-day notice

The single most damaging late-fee error in a Maine eviction is confusing the fee with rent. The seven-day notice under Title 14 section 6002 is about rent arrears, and the tenant cures by paying rent plus the landlord’s actual filing and service fees, not late fees. Keep the arrears figure to rent alone. If a valid four percent late fee is owed, collect it separately in small claims, never through the nonpayment case.

Takeaway

A Maine seven-day notice to quit under Title 14 section 6002 is based on rent arrears, not late fees. A tenant reinstates by paying the rent due plus the landlord’s actual filing and service costs before the writ issues — not a stack of late fees. A valid four percent late fee is collectible as a separate debt in small claims, never through the eviction.

Special Cases: Mobile Homes and Subsidized Units

The four percent cap and fifteen-day grace period are the baseline for ordinary residential rent, but a couple of categories of housing carry their own layered rules, and it is worth knowing where they differ.

Mobile-Home Parks

A mobile-home park lot is governed by its own statute, but the late-fee rule is essentially identical. Under Maine Revised Statutes Title 10 section 9097-C, part of the mobile-home park chapter, a park owner may not assess a late-payment penalty that exceeds four percent of one month’s rent, may not charge it until the rent is fifteen days late, and must have given the tenant written notice of the possible penalty when the rental agreement was signed. So a homeowner renting a lot in a Maine mobile-home park enjoys the same four percent cap, the same fifteen-day grace period, and the same disclosure protection as an ordinary residential tenant — just under a parallel statute in Title 10 rather than Title 14.

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, so the program rules ride on top of Maine’s four percent cap. The state ceiling still applies as an outer limit, but it applies within the narrower band the program allows, and some programs forbid a late fee on the subsidy portion outright.

Commercial Leases

The whole analysis on this page is about residential tenancies. Title 14 section 6028 protects residential renters, and a commercial lease is not governed by the same four percent cap or fifteen-day grace period. Commercial late fees are largely a matter of contract, judged under ordinary contract principles, so a business tenant cannot assume the residential protections apply to a store or office lease.

Takeaway

Mobile-home park lots get the same four percent cap and fifteen-day grace under Title 10 section 9097-C, subsidized tenancies limit a late fee to the tenant’s share and may bar it, and commercial leases fall outside Title 14 section 6028 entirely. The residential rule is the baseline; these categories layer their own limits on top.

Local Rules and Municipal Practice

Maine’s late-fee protection is set at the state level, and the four percent cap and fifteen-day grace period apply statewide, so the core rule does not change from Portland to Bangor to a small rural town. Unlike some states where big cities pile local rent-control ordinances on top of state law, Maine’s uniform statute means the same four percent ceiling governs almost everywhere in the state.

That said, some Maine municipalities — Portland most notably, which has adopted rent-control and tenant-protection measures — regulate other parts of the landlord-tenant relationship, such as rent increases and just-cause requirements. A landlord in a municipality with its own housing ordinances should confirm whether any local rule touches late fees or payment timing, and a tenant should check whether the city offers protections beyond the state baseline. Where a local ordinance is more protective, it controls; it can never allow a fee larger than the state four percent cap.

Check the local ordinance where one exists

Because Maine’s four percent cap and fifteen-day grace period are statewide, the state rule is the floor of protection everywhere. In a municipality like Portland that has its own tenant-protection ordinance, confirm whether any local rule adds to the state baseline on late fees, grace periods, or notice. A local rule can be stricter on the landlord, never more permissive than Title 14 section 6028.

Takeaway

Maine’s four percent cap and fifteen-day grace period apply statewide, so the core late-fee rule is the same across the state. Some cities such as Portland add tenant protections in other areas; where a local ordinance touches late fees it can only be stricter, never allow a fee above the state cap.

How a Tenant Contests an Unlawful or Excessive Late Fee

Because Maine’s tests are numeric, a tenant challenging a late fee has an easy checklist. Run the fee against three questions under Title 14 section 6028: was it charged before the rent was fifteen days late; does it exceed four percent of one month’s rent; and was the possibility of the fee disclosed in writing at lease signing? A “no” on the disclosure, a “yes” on charging early, or an amount over four percent each makes the fee unlawful, and the tenant does not have to argue reasonableness to prove it.

Steps a Maine Tenant Can Take Against a Bad Late Fee

Check the three numeric tests

Confirm whether the fee was charged before day fifteen, whether it exceeds four percent of a month’s rent, and whether the lease disclosed the fee in writing at signing. Any failure makes the fee unlawful under Title 14 section 6028.

Ask the landlord to correct or drop it

Put it in writing, cite Title 14 section 6028, and ask the landlord to remove the fee if it was premature, over four percent, or never disclosed. A clear statutory citation often resolves it without a fight.

Raise it if it hits a nonpayment case

If the landlord folded a late fee into the arrears for a seven-day notice under Title 14 section 6002, point out that the cure amount is rent plus actual filing and service costs, not late fees, and that a fee within the first fifteen days is unlawful anyway.

Dispute a deposit deduction

If the landlord took an unlawful late fee from the security deposit, challenge it in the deposit accounting and, if needed, in small claims court to recover it, a step governed by Maine’s security deposit rules.

Use small claims and keep records

A tenant can sue in small claims court to recover an overcharge above four percent or a fee charged during the grace period. Keep written records of every due date, payment date, and fee charged throughout the tenancy.

Takeaway

A Maine tenant contesting a late fee runs a three-part checklist: charged before day fifteen, over four percent of a month’s rent, or never disclosed in writing — any one is a violation of Title 14 section 6028. Ask the landlord to correct it in writing, raise it against a nonpayment case, dispute a deposit deduction, and use small claims to recover an overcharge.

The Maine Landlord and Tenant Playbook

Maine’s fixed numbers reward discipline on both sides. For landlords, a fee that stays inside the three rules holds up cleanly; for tenants, knowing the three tests keeps you from paying money you do not owe.

How to Handle a Late Fee the Compliant Way in Maine

Disclose the fee in writing at lease signing

Landlords: put the late-fee clause in the lease itself, stating that a penalty of up to four percent of one month’s rent may apply, so the written-disclosure requirement of Title 14 section 6028 is satisfied at the start of the tenancy.

Wait the full fifteen days before charging

Never assess a late fee until the rent is at least fifteen days late. If rent is due on the first, the earliest a lawful fee can attach is the sixteenth. Charging earlier violates the statute and gives the tenant a clean defense.

Cap the fee at four percent of a month’s rent

Calculate four percent of the actual monthly rent and never exceed it. A flat fee is fine only if it stays under that figure for the unit. Do not add per-day or escalating charges; the cap is per late payment.

Keep the fee out of the eviction arrears

Never fold a late fee into the arrears for a seven-day notice under Title 14 section 6002. Demand only rent, and let the tenant cure with rent plus your actual filing and service costs. Collect any valid late fee separately in small claims.

Tenants: verify before you pay

Check that the fee was disclosed in the lease, that fifteen days have passed, and that it is no more than four percent of a month’s rent. Dispute in writing anything charged early, over the cap, or never disclosed, and keep your payment records.

Need the eviction notice itself?

If a tenant is genuinely behind on rent, the correct tool is a rent-based seven-day notice, not a late-fee demand. See our Maine eviction notice laws guide and the broader library of late fee laws by state. Keep the arrears figure to rent alone, and pursue any valid four percent late fee separately. Always verify current law before serving.

Lawful Versus Unlawful: Common Scenarios

✓ Usually Lawful

  • Four percent, charged on day sixteen. A fee at or below four percent of a month’s rent, disclosed in the lease, charged only after the rent is fifteen days late.
  • Modest flat fee under the cap. A fixed late fee that, for the unit’s actual rent, always works out to four percent or less — disclosed at signing.
  • Fee collected separately. A valid late fee pursued in small claims, kept out of the seven-day notice and the arrears figure.
  • Returned-check remedy. The check amount, costs, twelve percent interest, and a civil penalty under Title 14 section 6071 — kept distinct from the late fee.

✕ Unlawful

  • Fee charged before day fifteen. Any late penalty applied during the fifteen-day grace period violates Title 14 section 6028.
  • Fee above four percent. A flat or percentage charge that exceeds four percent of one month’s rent; only four percent is collectible at most.
  • Fee never disclosed. A late fee the lease never mentioned in writing at signing — unenforceable no matter how late the rent.
  • Late fee as rent. Folding a late fee into the arrears for a seven-day notice, or making paying it a condition of curing.

The Best Late Payment Is the One That Never Happens

Most late-rent and bounced-check problems trace back to a tenant whose payment history showed red flags before move-in. Comprehensive credit, income, and eviction-history reports surface prior payment problems before you ever sign a lease.

Frequently Asked Questions

Is there a legal limit on late fees in Maine?

Yes. Maine sets a hard statutory cap. Under Maine Revised Statutes Title 14 section 6028, a landlord may not assess a late-payment penalty that exceeds four percent of the amount of rent due for one month. Unlike states that use an open-ended reasonableness test, Maine fixes a clear number: four percent of a month’s rent is the ceiling, and any fee above it is unlawful. The cap applies to the penalty for a given late payment, not four percent stacked per day or per week. Always verify the current statute before charging or paying a fee.

Does Maine have a grace period for late rent?

Yes, and it is unusually strong. Under Maine Revised Statutes Title 14 section 6028, a rent payment is not legally late until fifteen days have passed from the date it was due, and a landlord may not assess any late fee until the rent is at least fifteen days late. This fifteen-day grace period is set by statute, not by the lease, so it applies even if the lease tries to shorten it. A fee charged on day two, day five, or day ten is unlawful because the rent is not yet late for penalty purposes.

How much can a Maine landlord charge as a late fee?

No more than four percent of one month’s rent, and only after the rent is fifteen days late. For example, on rent of one thousand two hundred dollars a month, four percent is forty-eight dollars, and that is the maximum penalty the landlord may charge for that late payment. A landlord who charges a flat fifty or seventy-five dollars on rent where four percent works out lower has overcharged. The four percent cap under Maine Revised Statutes Title 14 section 6028 is the outer limit, and the landlord may always charge less.

Does a late fee have to be in the written lease in Maine?

Yes. Maine Revised Statutes Title 14 section 6028 says a landlord may not assess a late-payment penalty unless the landlord gave the tenant written notice, at the time they entered into the rental agreement, that a penalty of up to four percent of one month’s rent may be charged for late rent. The disclosure must be made when the tenancy begins, not invented later. If the lease is silent about a late fee, or the landlord never disclosed it in writing at the start, there is no enforceable late fee to collect, no matter how late the rent is.

What is the returned-check or NSF fee in Maine?

A bounced rent check is governed by Maine Revised Statutes Title 14 section 6071, the dishonored-check statute, not by the late-fee rule. If a check is returned and the drawer does not pay within the statutory demand window, the holder may recover the amount of the check, court costs, the processing charges, and interest at twelve percent per year from the date of dishonor, and a court may add a civil penalty of up to one hundred fifty dollars. A second dishonored check to the same payee within a year can trigger enhanced liquidated damages. This remedy is separate from any four percent late fee.

Can a landlord include a late fee in a Maine 7-day notice to quit?

No. A Maine seven-day notice to quit for nonpayment under Maine Revised Statutes Title 14 section 6002 is based on unpaid rent, and it can only be served once the tenant is at least seven days in arrears on rent. A late fee is not rent. Because the four percent penalty cannot even be charged until rent is fifteen days late, and the notice targets rent arrears, folding a late fee into the amount demanded to cure risks overstating the arrears and undermining the notice. Demand only rent to reinstate the tenancy; collect any valid late fee separately.

Can unpaid late fees lead to eviction in Maine?

Not on their own. Maine’s seven-day notice to quit under Maine Revised Statutes Title 14 section 6002 is grounded in unpaid rent, not late fees. If a tenant pays all rental arrears and any filing and service fees the landlord actually expended before the writ of possession issues, the tenancy is reinstated, so a disputed late fee should not be the thing that forces a tenant out. A landlord may pursue an unpaid, lawful four percent late fee as a separate debt in small claims, but not by using the fast eviction process to collect it as if it were rent.

When can a Maine landlord first charge a late fee?

Only after the rent is fifteen days late. Maine Revised Statutes Title 14 section 6028 defines rent as late once fifteen days have passed from the due date, and bars any penalty before that point. So if rent is due on the first, the earliest a lawful late fee can attach is the sixteenth. The lease cannot shorten this window. Once the rent is fifteen days late and the required written disclosure was made at the start of the tenancy, the landlord may assess a penalty of up to four percent of one month’s rent, and no more.

Is a percentage-based late fee legal in Maine?

Maine’s cap is itself expressed as a percentage: four percent of one month’s rent under Maine Revised Statutes Title 14 section 6028. A percentage fee is legal as long as it does not exceed that four percent ceiling and is not charged before the rent is fifteen days late. A flat-dollar fee is also fine so long as, in practice, it never exceeds four percent of the monthly rent for that unit. What is unlawful is any structure, percentage or flat, that produces a charge above four percent of a month’s rent or that hits the tenant during the fifteen-day grace period.

How does a Maine tenant fight an unlawful or excessive late fee?

Start by checking two things against Maine Revised Statutes Title 14 section 6028: was the fee charged before the rent was fifteen days late, and does it exceed four percent of one month’s rent? Either problem makes the fee unlawful. Ask the landlord in writing to correct or drop it, and cite the statute. A tenant can dispute a wrongful late fee deducted from a security deposit, raise it if the landlord tries to fold it into a nonpayment case, or sue in small claims to recover an overcharge. Keep written records of the due dates, payment dates, and every fee charged.

Do late-fee rules differ for mobile-home parks in Maine?

The rule is essentially the same but sits in its own statute. For a mobile-home park lot, Maine Revised Statutes Title 10 section 9097-C mirrors the residential rule: the park owner may not charge a late-payment penalty exceeding four percent of one month’s rent, may not charge it until the rent is fifteen days late, and must have disclosed the possible penalty in writing when the rental agreement was signed. So a homeowner renting a lot in a Maine mobile-home park enjoys the same four percent cap and fifteen-day grace period as an ordinary residential tenant, under a parallel statute.

Can a Maine landlord charge both a late fee and interest on late rent?

The four percent penalty under Maine Revised Statutes Title 14 section 6028 is the cap on what the landlord may charge for the late payment itself, so a landlord cannot layer a separate interest charge on top that pushes the total penalty above four percent of a month’s rent. The twelve percent interest figure in Maine law belongs to the dishonored-check statute, Title 14 section 6071, and applies to a bounced check, not to ordinary late rent. For an ordinary late payment, four percent of one month’s rent is the ceiling, and stacking extra charges on top of it is not allowed.

Does a lease clause let a Maine landlord exceed the four percent cap?

No. Maine Revised Statutes Title 14 section 6028 is a statutory ceiling, and a lease cannot contract around it. A clause that sets a late fee above four percent of one month’s rent, or that tries to charge the fee before the rent is fifteen days late, is unenforceable to that extent even if the tenant signed it. The written disclosure at lease signing is required to charge any fee at all, but it does not unlock a higher fee. The lease can offer the tenant more protection than the statute, never less.
