Security Deposit Laws in New Hampshire: What Landlords Can and Can't Take

Security deposits are one of the most contested issues in the landlord-tenant relationship — and for good reason. According to a 2023 survey by the Apartment List, more than 1 in 4 renters reported losing all or part of their security deposit unfairly, and disputes over deposits account for a significant share of small claims court filings across the country. In New Hampshire, the law is actually quite protective of renters — but only if you know what those protections are. Many tenants hand over hundreds or even thousands of dollars at move-in and never see that money again, not because the landlord had a legal right to keep it, but because the tenant didn't know how to challenge an unlawful deduction. This article breaks down New Hampshire's security deposit laws in plain language: how much a landlord can charge, what they can legally deduct, how and when they must return the deposit, and what you can do if they break the rules.

The Foundation: New Hampshire RSA Chapter 540-A

New Hampshire's security deposit rules are codified primarily under RSA Chapter 540-A, titled 'Prohibited Practices.' This is the core tenant protection statute in the state, and it governs everything from security deposit limits and return timelines to prohibited landlord behaviors like shutting off utilities or unlawful entry. For renters, this chapter is essential reading — or at least essential knowing. The statute was designed to give residential tenants meaningful leverage, including the ability to sue for damages when a landlord violates the rules. Unlike some states where security deposit violations result in minor penalties, New Hampshire law allows tenants to recover actual damages plus a civil penalty of $1,000 per violation in certain circumstances. That's real money — and a real deterrent.

How Much Can a Landlord Charge for a Security Deposit in New Hampshire?

Under RSA 540-A:6, a landlord in New Hampshire may not charge a security deposit that exceeds one month's rent. This is a hard cap — not a guideline, not a suggestion. If your monthly rent is $1,400, your landlord cannot legally require a deposit of more than $1,400. This limit applies to residential tenancies only and covers any payment made to the landlord specifically as security for the performance of the lease — meaning the landlord cannot work around the cap by calling the deposit something else, like a 'damage fund' or 'reservation fee,' if it functions as a security deposit.

There is one important exception to the one-month cap: pet deposits. New Hampshire law does not explicitly prohibit landlords from charging an additional pet deposit on top of the standard security deposit, though the practice and enforceability can vary depending on lease terms. If you paid both a security deposit and a separate pet deposit, you should review your lease carefully and consider consulting a tenant's rights organization to understand how each is governed. The New Hampshire Legal Assistance (NHLA) organization provides free legal aid to income-eligible residents and can help clarify these situations.

Last Month's Rent: Is It Separate?

Some landlords ask for both a security deposit and the last month's rent at move-in. In New Hampshire, a 'last month's rent' payment is treated as prepaid rent, not as a security deposit — but the law has teeth here too. Under RSA 540-A:6, if a landlord collects last month's rent in advance, they must pay the tenant interest on that amount at a rate equal to the rate paid on a regular savings account by the bank or lending institution where the funds are deposited. This interest accrues annually and must be returned to the tenant when they vacate. Failing to pay this interest is a violation of RSA 540-A, which carries those same civil penalties mentioned above.

Where Must the Deposit Be Held?

New Hampshire law requires that security deposits be kept in a separate, interest-bearing bank account. The landlord must deposit the funds within 25 days of receiving them. The account must be maintained at a bank or federally insured lending institution doing business in New Hampshire, and it must be separate from the landlord's personal or operating accounts. This is an important safeguard: it prevents landlords from spending the deposit during the tenancy and then being unable to return it at move-out.

The interest earned on a security deposit belongs to the tenant. Each year, the landlord must either pay the tenant the interest earned or apply it to the tenant's rent, at the tenant's option. When the tenancy ends, any remaining interest must be returned along with the principal deposit amount (minus any lawful deductions). If a landlord fails to maintain the deposit in a compliant account, this is itself a violation of RSA 540-A — and the tenant may have grounds to reclaim the full deposit plus penalties.

What Can a Landlord Legally Deduct From Your Deposit?

This is where most deposit disputes begin. After a tenant moves out, a landlord can only deduct from the security deposit for specific, lawful reasons. New Hampshire law is clear that a security deposit is not a slush fund for general repairs or for refreshing a unit between tenants. The permitted deductions are narrow by design.

Lawful Reasons for Deductions

• Unpaid rent or other amounts owed under the lease at the time of move-out
• Physical damage to the rental unit caused by the tenant, their household members, or guests — beyond normal wear and tear
• Costs to restore the unit to its condition at the start of the tenancy, accounting for normal wear and tear
• Unpaid utility bills that the tenant was responsible for under the lease and that are in arrears at move-out
• Costs associated with the tenant abandoning the unit, if the landlord must re-rent it (in some circumstances)

What Is 'Normal Wear and Tear'?

The phrase 'normal wear and tear' is the most important concept in security deposit law — and the most frequently misunderstood. In New Hampshire, as in most states, landlords cannot deduct for deterioration that results from ordinary, reasonable use of the property. This is the natural aging and decline that happens to a property simply because someone was living in it. Landlords are expected to account for this when they price their rent and plan for maintenance. Deducting for normal wear and tear is unlawful, period.

Normal wear and tear typically includes things like: minor scuffs or fading on walls from everyday living, carpet wearing down from regular foot traffic over years of tenancy, small nail holes from hanging pictures (a standard practice), fading or slight discoloration of fixtures from age and sunlight, and loose hinges or handles on doors and cabinets. Tenant damage, on the other hand, is something that goes beyond that baseline: large holes in walls, burns or deep stains in carpet, broken window panes, missing fixtures, significant unauthorized alterations, or damage from pets or negligence.

Gray Areas and Common Disputes

The line between wear and tear and tenant damage is often disputed. For example, a 10-year-old carpet that is stained because a tenant had a dog is different from a 1-year-old carpet with a large pet urine stain. Courts in New Hampshire will often look at the age of the item, its expected useful life, and the degree of damage when determining whether a deduction is lawful. A landlord who charges a tenant for the full replacement cost of a 15-year-old carpet is very likely overreaching. The tenant would only be responsible for the depreciated value of the carpet, not its replacement cost.

• Painting: Repainting after a long tenancy is generally considered normal wear and tear. Painting over significant crayon drawings, smoke staining, or unauthorized paint colors may be deductible.
• Cleaning: If the unit was professionally cleaned before move-in, the landlord may charge for professional cleaning at move-out if the tenant left the unit significantly dirtier — but not for routine cleaning.
• Appliances: Deductions for appliances depend on age, condition at move-in, and what caused the damage. A broken stove knob after 5 years may be wear and tear. A shattered oven door from misuse is likely not.
• Fixtures: Broken towel bars, toilet seats, or light fixtures may be wear and tear if they're old; they may be damage if they were brand new at move-in.

The Move-In and Move-Out Checklist: Your Most Important Protection

Under RSA 540-A:6, IV, landlords in New Hampshire are required to give tenants a written statement of the condition of the rental unit at the beginning of the tenancy. This must be provided within five days of the tenant moving in, and the tenant has the right to dispute any items on the checklist within five days of receiving it. Both parties should sign the checklist. At move-out, the same checklist becomes the benchmark for any damage claims. If the landlord did not provide a move-in condition statement as required by law, they forfeit the right to make deductions from the security deposit. This is a significant protection — and one that many tenants don't know about.

Even if your landlord provides a checklist, you should always supplement it with your own documentation. Walk through the entire unit on the day you move in and take time-stamped photos or video of every room, every wall, every appliance, every fixture. Note any pre-existing damage — scratches, stains, chips, broken items — in writing and send a follow-up email to your landlord documenting what you found. This creates a paper trail that is invaluable if there's a dispute later. The same applies when you move out: photograph everything before you hand over the keys.

When Must a Landlord Return Your Security Deposit?

New Hampshire law sets a firm deadline for returning security deposits. Under RSA 540-A:7, a landlord must return the security deposit — along with a written, itemized list of any deductions — within 30 days of the termination of the tenancy. The clock starts when the tenancy actually ends, not when you give notice or when your lease expires. In practice, this usually means 30 days from the date you vacate and return the keys.

The itemized statement must explain every deduction in enough detail that the tenant can understand what is being claimed. Vague entries like 'repairs: $500' are not sufficient. A landlord must specify what was damaged, what repairs were made, and how the cost was calculated. If receipts or invoices are available, best practice is to include them — and if a tenant requests supporting documentation, they should receive it.

What If the Landlord Misses the 30-Day Deadline?

This is where New Hampshire law becomes particularly tenant-friendly. If a landlord fails to return the deposit or provide an itemized statement within 30 days, the tenant is entitled to the full return of the deposit — regardless of whether some deductions might otherwise have been lawful. The landlord loses the right to make any deductions by missing the deadline. Additionally, a landlord who willfully fails to comply with these requirements may be liable to the tenant for civil penalties under RSA 540-A:4, which can reach $1,000 per violation, plus the tenant's actual damages and attorney's fees.

1. 1Document your move-out date clearly — send a written notice, email, or text stating the date you are vacating and returning keys.
2. 2Return all keys, access cards, and parking passes to create a clear record of when the tenancy ended.
3. 3Provide your forwarding address in writing so the landlord cannot claim they didn't know where to send the deposit.
4. 4Mark your calendar for 30 days from your move-out date. If you haven't received the deposit or an itemized statement by then, the deadline has passed.
5. 5If the deadline passes without action, send a written demand letter to the landlord requesting return of the full deposit immediately.
6. 6If the landlord still doesn't respond or refuses, file a claim in New Hampshire's Circuit Court — District Division (small claims court) for recovery of the deposit plus civil penalties.

How to File a Claim in New Hampshire Small Claims Court

If your landlord refuses to return your deposit or makes unlawful deductions, you have the right to take them to small claims court in New Hampshire. The state's Circuit Court — District Division handles small claims for amounts up to $10,000, which covers most security deposit disputes. Filing fees are relatively low (typically around $90-$130 depending on the claim amount), and you do not need an attorney, though you may choose to have one.

To file, you'll submit a Small Claim form (available at the courthouse or online through the New Hampshire Judicial Branch website) along with your filing fee. You'll need to describe your claim, state the amount you're seeking, and provide the landlord's name and address for service. The court will schedule a hearing, at which you and the landlord will each present your side. Bring all your documentation: your lease, the move-in checklist (or evidence that none was provided), move-in and move-out photos, correspondence with the landlord, the itemized statement (or evidence that none was sent), and any receipts or estimates relevant to disputed charges.

Special Situations: Foreclosure, Sale of Property, and Death of a Landlord

What happens to your security deposit if the property is sold while you're a tenant? Under New Hampshire law, the new owner takes the property subject to the existing tenancy — and that includes the security deposit obligation. The original landlord is required to transfer the deposit to the new owner at the time of sale, and the new owner becomes responsible for returning it in compliance with the law when the tenancy ends. If the deposit was not properly transferred, both the original and new landlord may bear liability. If your rental property is sold, ask in writing who is holding your security deposit and confirm the amount — do this early, not at move-out.

In the event of a foreclosure, the situation is more complex. Federal law (the Protecting Tenants at Foreclosure Act) provides certain protections for tenants in foreclosure situations, including notice requirements before eviction. New Hampshire law also provides that security deposits must follow the property through foreclosure. If the bank or new owner after foreclosure fails to return your deposit as required, you may still have a claim — though pursuing it can require legal assistance. The New Hampshire Legal Assistance (nhla.org) is the best starting point in these situations.

Local and City-Level Considerations in New Hampshire

New Hampshire is a state with strong preemption — meaning state law generally governs landlord-tenant relationships, and most municipalities do not have separate rent control or security deposit ordinances that go beyond state law. However, some cities have local housing codes and inspection requirements that interact with the move-in/move-out process. Manchester, Nashua, Concord, and Portsmouth all have active housing departments with code enforcement divisions. If your rental has housing code violations that existed before you moved in, this could affect your liability for any damage claims — a documented pre-existing condition that the landlord was aware of should not be charged to the tenant.

It's also worth knowing that New Hampshire does not have rent control anywhere in the state (state law actually prohibits municipalities from enacting rent control), but tenant protections under RSA 540-A apply statewide, uniformly. Whether you're renting in a rural town or in downtown Manchester, the same rules apply to your security deposit.

Final Thoughts: Your Deposit Is Your Money

Security deposits represent a meaningful amount of money for most renters — often representing hundreds or thousands of dollars that could be the difference between making your next first month's rent or struggling to get into a new home. New Hampshire law is designed to protect that money from being improperly kept by landlords, but the law only works if you know and enforce your rights. Document everything. Understand the checklist requirement. Know the 30-day rule. And don't be afraid to pursue what you're owed through the court system — it exists precisely for situations like these.

The data is clear: renters who understand their rights are dramatically more likely to recover their deposits. A 2022 report by the National Housing Law Project found that tenants who sent a formal written demand letter before filing in small claims court recovered their deposits in full more than 60% of the time — often before ever setting foot in a courtroom. Knowledge is your first and most powerful tool.
