Effective since Maine's statehood on March 15, 1820, commercial lease terms, including late fees, are governed by general contract law rather than specific statutory caps. Maine's residential late fee statute (14 MRS § 6028)—which prohibits a landlord from charging more than 4% of a month's rent and mandates a strict 15-day grace period—is one of the most tenant-friendly in the country. It does not apply to commercial leases.
Official Law Citation: Late fees in commercial leases are governed by general contract law and strictly by the negotiated terms of the lease agreement.
Freedom of Contract
In a commercial lease, a late fee is essentially "liquidated damages," negotiated in advance to compensate the landlord for the administrative hassle and loss of use of funds when a commercial tenant fails to pay on time.
Because the state assumes both parties are sophisticated businesses, there are no statutory limits on the amount or the timing.
- No 15-Day Grace Period: A commercial landlord does not have to wait 15 days. A lease can dictate that rent is due on the 1st, and a late fee is automatically generated if payment is not received by 5:00 PM on the 5th.
- No 4% Maximum: A commercial landlord can negotiate significantly higher penalties. A fee of 5%, 10%, or a flat fee of several hundred dollars per occurrence is common and entirely legal, provided it is established in the signed lease.
Liquidated Damages vs. Unlawful Penalties
While landlords have immense flexibility, a late fee that is excessively high can still be challenged in court. If a landlord charges a $5,000 late fee on a $2,000 monthly rent payment, a Maine judge is likely to strike it down. Under general contract law, the fee must be a reasonable estimation of the landlord's actual damages, not a purely punitive tax designed to bankrupt the tenant.
Default Interest Rates
In addition to a flat late fee or a percentage penalty, sophisticated commercial leases in Maine often include a "Default Interest Rate."
- If the tenant misses a payment, the outstanding balance begins accruing interest (e.g., 12% or 15% annually, calculated daily) until the balance is paid in full.
- This prevents a tenant from using the landlord as a zero-interest bank during cash flow crunches.
The Importance of the Non-Waiver Clause
If a commercial tenant consistently pays rent on the 10th of the month, and the landlord consistently accepts it without enforcing the stated late fee, the tenant could argue in court that the landlord implicitly "waived" their right to enforce the 1st of the month deadline through their ongoing actions.
To combat this, every commercial lease in Maine requires a rigid Non-Waiver Clause. This clause essentially states:
"The landlord's failure to enforce a late fee or right of default on one occasion does not constitute a waiver of the landlord’s right to strictly enforce the lease terms on any subsequent occasion."
Even with this clause, landlords should be extremely cautious about establishing a patterned history of accepting late rent without penalty or protest.
Serving Default Notices
Unlike residential evictions which demand a rigid 7-day notice for non-payment, the commercial lease dictates the timeline. If the lease states a tenant has 5 days to "cure" a monetary default (meaning pay the rent plus any late fees), the landlord can serve a formal Notice of Default exactly according to that timeline.

Frequently Asked Questions
▶What are the Maine landlord-tenant laws every property owner should know?
Maine's landlord-tenant laws strive to balance the property rights of landlords with concrete habitability and transparency protections for tenants. While the state statutes apply broadly, landlords must also be acutely aware of local ordinances in municipalities like Portland, which enforce stricter rent control and eviction guardrails. This guide covers the essential compliance requirements for property owners and landlords.

The Maine eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Maine. The full court process varies but typically takes several weeks.
Read the complete guide▶What are the Maine security deposit rules and return deadlines?
Maine has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Maine rent increase laws and caps for landlords?
Maine has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether Maine has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Maine?
Maine has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee. Late fee provisions must be stated in the lease agreement, and fees must be reasonable. Check Maine state law and any applicable local ordinances for the exact grace period and late fee limits that apply to your rental property.
Read the complete guide▶What disclosures must Maine landlords provide to tenants?
Maine landlords must provide certain disclosures to tenants before or at the time of lease signing. Common required disclosures include lead-based paint hazards (for pre-1978 buildings, a federal requirement), the identity of the landlord or property manager, and any known material defects in the property. Additional state-specific disclosures may include flood risk, mold hazards, and environmental conditions.
Read the complete guide▶What are the Maine lease requirements for rental properties?
Maine recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting. Certain lease clauses that waive tenant statutory rights may be void and unenforceable under Maine law.
Read the complete guide▶What are Maine landlord maintenance obligations and habitability standards?
Maine landlords must maintain rental properties in a condition that is fit for habitation and complies with applicable building, housing, and health codes. This includes maintaining structural integrity, plumbing, heating and cooling systems, electrical systems, and pest control.
