Most of what you'll find online about Maine security deposits is wrong. I've read the blog posts that tell you the statute lives in Chapter 710, that tenants over 62 are capped at one month, that you owe interest on the money. None of that is in the Maine Revised Statutes. What is in the statutes is a deadline that forfeits your entire right to withhold if you miss it by a day, and a damages provision that doubles what you kept and hands the tenant's lawyer a bill you pay. Here's the actual law, section by section, and what I do about it.
This post is educational, not legal advice. Maine landlord-tenant law is particular, and the facts of your situation matter. For advice on a specific property or tenant situation, talk to a Maine-licensed attorney or contact Pine Tree Legal Assistance at ptla.org.
How long do you have to return a security deposit in Maine?
Two deadlines, and which one applies depends on your paperwork. If you have a written lease, you have up to 30 days. If the tenancy is at will, you have 21 days from termination or from surrender and acceptance of the premises, whichever happens later. Miss either one and you forfeit the right to withhold anything.
The operative section is 14 MRSA §6033, not §6034. That distinction matters because §6033 sets the deadline and §6034 sets the penalty, and people conflate them constantly.
Read §6033(2)(A) closely. It says the written lease deadline is "within the time, not to exceed 30 days, stated in the agreement." That phrasing catches landlords. If your lease says you'll return the deposit in 14 days, 14 days is your deadline. You wrote it, you're bound by it, and 30 days is only a ceiling. I've seen owners use a downloaded lease template with a 10-day return clause they never noticed, then blow past it on a routine turnover.
For a tenancy at will, §6033(2)(B) gives 21 days running from termination or surrender and acceptance, whichever is later. Tenancies at will are common in central Maine, especially on older month-to-month arrangements that were never papered. If you don't have a signed written lease in the file, assume 21 days.
What you actually have to send
Returning the deposit is one option. The other is a written itemized statement of the reasons for retention, and here's the part landlords skip: §6033(2) requires that the statement "must be accompanied by a full payment of the difference." A statement without the balance check is not compliance. You cannot send the accounting now and the money later.
Delivery is the one place the statute cuts you a break. The landlord "is deemed to have complied with this section by mailing the statement and any payment required by this section to the last known address of the tenant." If the tenant left no forwarding address, mail it to the unit anyway. Certified mail with return receipt is what I use, because the receipt is what you hand the judge.
If you miss the deadline, §6033(3) is unforgiving: the landlord "shall forfeit his right to withhold any portion of the security deposit." Not the disputed portion. The whole thing. A tenant who left $2,400 in damage on a $1,200 deposit still gets the full $1,200 back if your statement went out on day 31.
What is the maximum security deposit you can charge in Maine?
Two months' rent. 14 MRSA §6032 says a lease or tenancy at will agreement may not require a security deposit equivalent to more than the rent for two months. That's the ceiling statewide. There is no senior exception, no exception for pets, and no exception for a tenant with poor credit.
The trap is in the definition, not the number. Under 14 MRSA §6031, a security deposit is any advance of money "regardless of its denomination" whose primary function is to secure performance of the lease. Call it a pet deposit, a cleaning deposit, a key deposit, a damage deposit. If its job is to secure performance, it counts against the two-month cap.
So a $1,400 unit with a $2,800 security deposit plus a $400 pet deposit is at $3,200 on a $2,800 ceiling. That's a violation on its face, and the tenant doesn't have to prove damage to raise it.
Two things I want to correct here, because both circulate widely:
- There is no one-month cap for tenants 62 and older. Several national rental-software blogs publish this. It is not in §6032 or anywhere in Chapter 710-A.
- Maine does not require you to pay interest on a residential security deposit or to hold it in an interest-bearing account. Nothing in §§6031 through 6039 imposes that.
The one genuine exception is mobile home park lots, which are governed by a different title entirely. Under 10 MRSA §9098, a lessor of a mobile home park lot may not require a security deposit greater than three months' rent. If you rent lots rather than dwelling units, you're reading the wrong chapter.
What triggers double damages under 14 MRSA §6034?
A tenant sends you written notice of intent to sue. You have seven days. If you don't return the entire deposit inside that window, the law presumes you're wrongfully retaining it, and 14 MRSA §6034 makes you liable for double the wrongfully withheld portion plus the tenant's attorney's fees and court costs.
Three mechanics in that section are worth understanding separately.
- The seven-day notice under §6034(1). The tenant must give notice "no less than 7 days prior to commencing the action." This is your last off-ramp. Return the full deposit inside those seven days and the presumption never attaches.
- The doubling under §6034(2), which applies to "that portion of the security deposit wrongfully withheld," not automatically to the whole deposit. If you kept $900 and $600 of it was defensible, the exposure runs on the $300.
- The burden shift under §6034(3). The landlord "has the burden of proving that the landlord's withholding of the security deposit, or any portion of it, was not wrongful." You are the one who has to prove your case. The tenant doesn't have to disprove yours.
That third point is the whole ballgame, and it's why I'm obsessive about move-in documentation. In a deposit case you walk into court already carrying the load.
The attorney's fees are not discretionary once wrongful retention is established. The Law Court settled that in Robbins v. Foley, 469 A.2d 840 (Me. 1983), and it has held up.
The 2025 case every Maine landlord should read
In December 2025 the Maine Supreme Judicial Court decided Allaf v. Shoreline Holdings Five, LLC, 2025 ME 95. Tenants left a cockroach-infested Biddeford apartment by agreement with the landlord. The landlord kept the $1,795 deposit, argued the lease had never been properly terminated, and never sent an itemized statement. The Court found wrongful retention and awarded $3,590, double the withheld amount, plus fees. Emma Halas-O'Connor of Pine Tree Legal Assistance argued for the tenants.
The holding with the longest tail is procedural. The Court treated statutory attorney's fees as costs rather than damages, which means they sit on top of the small claims damages ceiling rather than inside it. A landlord who assumed small claims capped total exposure at the jurisdictional limit was wrong before Allaf and is clearly wrong now.
The good-faith defense, and why I don't rely on it
The presumption of wrongful retention is rebuttable. In Lyle v. Mangar, 2011 ME 129, 36 A.3d 867, the Law Court held that a landlord can overcome it by showing a good faith reason for the retention, and the landlord there prevailed despite never sending the written statement, because the tenant owed months of back rent.
That case gets cited to me by owners who want permission to skip the paperwork. My answer is that Lyle is a rescue, not a strategy. The landlord won on facts so lopsided that the missing statement didn't matter. Yours probably aren't. Send the statement.
What can you legally deduct from a Maine security deposit?
Section 6033(2) lists permitted reasons and says the list is not exclusive. Named in the statute: the cost of storing and disposing of unclaimed property, nonpayment of rent, and nonpayment of utility charges. Damage beyond normal wear and tear is deductible. Normal wear and tear is not, under §6033(1), full stop.
Maine defines the term rather than leaving it to argument. Section 6031 describes normal wear and tear as deterioration occurring "without negligence, carelessness, accident or abuse," and expressly excludes the cost of removing articles the tenant abandoned, including trash. A 1997 amendment added that where the unit was rented in habitable condition, cleaning costs to restore it to habitable condition are not normal wear and tear.
That last clause is narrower than landlords want it to be. It permits deducting for a unit returned uninhabitable. It does not permit charging every departing tenant a turnover cleaning fee. The Maine Attorney General's consumer guide, Consumer Rights When You Rent an Apartment, tells tenants directly that a landlord generally cannot use the deposit for routine cleaning or painting. Assume your tenant has read it.
| Condition at move-out | Normal wear and tear | Deductible damage |
|---|---|---|
| Carpet | Traffic-path wear after a multi-year tenancy | Burns, pet stains through to the pad, tears |
| Walls | Nail holes from hanging pictures, faded paint | Unapproved paint colors, large holes, crayon |
| Appliances | Worn oven racks, loose refrigerator shelf | Cracked glass cooktop, missing appliance parts |
| Cleaning | Light dust and ordinary surface soil | Grease buildup or filth leaving the unit uninhabitable |
| Left-behind property | Nothing | Storage and disposal costs under §6033(2) |
Property the tenant leaves behind
Abandoned property is governed by a separate statute in a different chapter, 14 MRSA §6013. You must place the property in storage in a safe, dry, secured location, then send written notice by first-class mail with proof of mailing to the tenant's last known address, including an itemized list. The notice tells the tenant that if they don't respond within seven days you may dispose of the property. If they do respond, you store it at least 14 more days.
The two statutes interlock, which is convenient. Follow §6013 and the storage and disposal costs become a §6033(2) deduction. Skip §6013 and you've created a conversion claim on top of your deposit problem.
Which Maine landlords are exempt from the security deposit law?
One exemption matters, and it's total. Under 14 MRSA §6037(2), the chapter does not apply to a dwelling unit in a structure containing no more than five units, one of which the landlord occupies. Owner-occupied five-or-fewer. If you qualify, the cap, the deadlines, and double damages all fall away.
This covers an enormous share of the housing stock in Bangor, Brewer, and Old Town. The classic Bangor triple-decker with the owner on the first floor is exempt. So is an owner-occupied four-unit in Orono.
Three cautions before you rely on it.
- The exemption turns on one structure, not one portfolio. Owning six units across two owner-occupied buildings does not disqualify you; owning a six-unit building you live in does.
- Occupancy has to be real and current. If you move out and rent your unit, the exemption goes with you, and the tenancy that started while you lived there is now covered.
- Bangor's local ordinance has no equivalent carve-out. Exempt from Chapter 710-A does not mean exempt from the city rules below.
The other exemption, §6037(1), applies where chapter provisions conflict with the terms of a federally guaranteed mortgage. It comes up rarely and is worth an attorney's read if you think it applies to you.
Where does Maine require you to hold the deposit?
In a segregated bank account, structured so your creditors can't reach it. 14 MRSA §6038 says a deposit may not be treated as an asset to be commingled and must sit in an account "beyond the claim of creditors of the landlord," naming a foreclosing mortgagee and a trustee in bankruptcy specifically.
You can pool every tenant's deposit into one escrow account. You cannot run deposits through your operating account, and you cannot spend them and true up at move-out. I've watched an owner with a refinance in progress discover the difference the hard way.
The tenant can ask where the money is
Section 6038 also gives the tenant a disclosure right. On request, you must disclose the name of the institution and the account number where the deposit is held. Most tenants never ask. The ones who do are usually building a file, which is a signal worth reading.
The penalty for a §6038 violation runs on a different track from double damages. The tenant recovers actual damages, or $500, or one month's rent, whichever is greatest, plus costs and potentially fees. On a $1,500 unit that's a $1,500 floor for commingling, independent of whatever you eventually returned.
What happens when you sell the building or die
14 MRSA §6035 covers termination of your interest by sale, assignment, death, or appointment of a receiver. You either transfer the deposits with a full accounting and written notice to each tenant of the transferee's name and address, or you return them. On a sale, the statute requires the accounting and transfer of funds to happen no later than at closing, with written proof to the buyer.
Do it properly and you're relieved of further liability while the buyer assumes the obligations. Do it sloppily and you're a defendant on deposits you no longer hold. I flag this at every listing appointment with an owner who's selling, because the closing attorney is not always tracking it and the deposits are rarely on anyone's checklist.
One more provision worth knowing: any lease clause purporting to waive a tenant's rights under this chapter is void as against public policy under 14 MRSA §6036. You cannot draft around any of this, and a tenant cannot agree to let you.
What do Bangor's rules add on top of state law?
Bangor's Chapter 282, Tenant Housing Rights, took effect in March 2023 and layers city requirements on top of Chapter 710-A. It does not change the deposit cap or the return deadlines. It does change your fees, your notice periods, and your paperwork at lease signing, and it is non-waivable.
What Chapter 282 requires inside city limits:
- Sixty days' written notice of any rent increase, notwithstanding the 45 days state law requires under 14 MRSA §6015. For an increase of 10% or more, state law's 75-day period is longer, so use 75.
- Application fees are banned outright. Screening fees are capped at actual cost or $75, whichever is less, chargeable only to a successful applicant and only when first month's rent is due. Records kept two years.
- The City's Tenant/Landlord Rights and Responsibilities disclosure goes to every tenant at commencement, with a signed acknowledgment you retain for two years.
Councilor Dina Yacoubagha, who pushed the ordinance through, told Maine Public when it passed that it was a "step in the right direction". Three years in, the screening fee cap is still the provision that catches new owners, particularly out-of-state investors running a national screening product that costs more than $75 a head.
If you also own in Portland, run two playbooks. Portland caps deposits at one month's rent and requires 90 days' notice for rent increases under its rent stabilization ordinance. A statewide lease template will put you out of compliance in one city or the other.
What happens if a tenant sues you over a deposit in Penobscot County?
Small claims, almost always. A Bangor-area case is filed in the Bangor District Court at the Penobscot Judicial Center, 78 Exchange Street. As of January 1, 2026 the small claims jurisdictional limit is $10,000, raised from $6,000 by P.L. 2025, ch. 261. Filing fees run $50 up to $4,500 and $120 above that.
The math changed with that increase. A two-month deposit on a $1,500 unit is $3,000; doubled it's $6,000, which used to sit right at the old ceiling before fees were even discussed. At $10,000 there's now room for the doubled amount and a fee award in the same proceeding, and Allaf confirmed fees ride on top of the cap regardless.
Maine's small claims procedure is unusual in one respect worth knowing: the plaintiff serves the defendant before filing, not after. The Maine Judicial Branch publishes the process and forms in A Guide to Small Claims Cases. You'll be served, then you'll see the claim.
What I tell owners who call me holding a seven-day notice: the decision point is now, not at the hearing. If your file has a signed move-in condition report, dated photos, an itemized statement, and proof of mailing inside the deadline, defend it. If any one of those is missing, write the check inside the seven days. The fee exposure alone will exceed the deposit.
What changed for Maine landlords in 2025 and 2026?
Less than the noise suggests. The 132nd Legislature did not amend the deposit cap, the return deadlines, or the double-damages provision. Chapter 710-A reads the same in 2026 as it did in 2024. Three things around the edges did move, and one older law took full effect.
The small claims ceiling went to $10,000 effective January 1, 2026, which is the change with the most direct effect on deposit litigation. Separately, LD 2176, sponsored by Sen. Jill Duson (D-Portland), became Public Law 2025, ch. 767 in April 2026. It rewrites landlord entry and disclosure rules and raises the unlawful entry penalty from $100 to $250. It does not touch security deposits.
LD 824, sponsored by Sen. Donna Bailey (D-York), would have capped pet deposits at $300 and pet rent at 1% of monthly rent. It died in April 2025. Maine still has no statutory cap on pet rent, and no cap on a pet deposit beyond the two-month ceiling that already swallows it under §6031's definition.
The fee-disclosure regime from LD 1490, enacted as P.L. 2023, ch. 594, took effect January 1, 2025. If you charge recurring fees beyond rent, the total-price disclosure and opt-in requirements now apply and are worth a separate look at your lease.
Context for why deposit disputes have gotten sharper: Maine's rental vacancy rate hit 2.2% in 2025, a record low for the series, per U.S. Census Bureau data published by the St. Louis Fed. National vacancy was 7.2% in the fourth quarter of 2025. A tenant who loses a deposit in this market often can't cover the next one, so they fight, and Pine Tree Legal Assistance is available to them at no cost.
How I handle deposits across our portfolio
The operating rules I use are shorter than the statute and mostly exist to keep §6034(3) from mattering. Because the burden of proof sits with the landlord, the file either wins the case before it starts or it doesn't.
- Deposits go into a segregated escrow account on the day they're received, never through operating funds.
- Every unit gets a signed, dated move-in condition report with photographs of every room, appliance, floor, and wall, stored so they can be produced two years later.
- The turnover calendar entry is created the day the tenant surrenders keys, dated to the applicable deadline minus five business days.
- Every deduction traces to an invoice or a receipt, not an estimate. A number I can't document is a number I don't take.
- The itemized statement and the balance check go out together, certified mail with return receipt, to the last known address, including when that address is the vacated unit.
Maine does not require a move-in checklist, a move-out walkthrough, or a photo record. I do all three anyway, because the statute that doesn't require them is the same statute that makes me prove my case. We manage hundreds of units across central and eastern Maine, and I have never regretted the fifteen minutes spent photographing a unit at move-in. You can see the towns and service areas we cover if you want to know whether we work where your property is.
Frequently Asked Questions
How long does a landlord have to return a security deposit in Maine?
Thirty days with a written lease, or the shorter period your lease states, since §6033(2)(A) treats 30 days as a maximum rather than a default. Twenty-one days for a tenancy at will, running from termination or from surrender and acceptance, whichever comes later. The deadline applies to the deposit or to an itemized statement sent with the balance owed.
What is the maximum security deposit a landlord can charge in Maine?
Two months' rent under 14 MRSA §6032, and that ceiling absorbs anything functioning as security regardless of what you call it. A pet deposit, cleaning deposit, or key deposit counts toward the same two months because §6031 defines a security deposit by its function, not its label. Mobile home park lots are capped separately at three months under 10 MRSA §9098.
Does Maine require landlords to pay interest on security deposits?
No. Nothing in 14 MRSA §§6031 through 6039 requires interest or an interest-bearing account for a residential security deposit. Section 6038 requires only that the money be segregated from your other funds and held beyond the reach of your creditors. Portland's local ordinance addresses interest where a landlord chooses an interest-bearing account, which is where some of the confusion originates.
What happens if a Maine landlord misses the deadline?
You forfeit the right to withhold any portion of the deposit under §6033(3), regardless of how much damage the tenant left. If the tenant then sends written notice of intent to sue and you don't return the full deposit within seven days, §6034 presumes wrongful retention, exposing you to double the withheld portion plus the tenant's attorney's fees and court costs.
Are owner-occupied buildings exempt from Maine's security deposit law?
Yes, if the structure has no more than five dwelling units and you occupy one of them. Section 6037(2) exempts that arrangement from the entire chapter, including the two-month cap, the return deadlines, and double damages. The test applies per structure, not per portfolio, and Bangor's local ordinance requirements still apply to exempt buildings inside city limits.
Can a Maine landlord charge a nonrefundable cleaning fee?
A fee whose function is to secure lease performance is a security deposit under §6031 no matter what the lease calls it, so labeling it nonrefundable does not remove it from the chapter. Section 6033(1) separately bars retaining any deposit for normal wear and tear. Cleaning costs are deductible where the unit was rented habitable and returned otherwise.
