New Hampshire Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights
New Hampshire limits security deposits to one month's rent or $100, whichever is greater, and requires landlords to return them within 30 days of the tenancy ending. Landlords must obtain prior consent before entering a rental unit, with a 48-hour notice requirement specifically for bed-bug inspections.
Security deposits in New Hampshire
New Hampshire places a low cap on security deposits: a landlord may collect no more than one month's rent or $100, whichever is the greater amount. For most tenants paying modern market rent, the cap works out to one month's rent. The landlord must return the deposit, along with a written itemization of any deductions, within 30 days of the tenant vacating the unit. Permitted deductions include unpaid rent, damage beyond normal wear and tear, and cleaning costs if the unit was left in an unusually dirty condition.
If the landlord fails to return the deposit or the itemized statement within 30 days, the tenant can sue in small claims court. New Hampshire courts can award double damages for a wrongful withholding of a security deposit. There is no requirement that deposits be held in a separate escrow account under New Hampshire law, but the landlord must be able to account for the funds.
| Key fact | Rule |
|---|---|
| Deposit cap | 1 month's rent or $100, whichever is greater |
| Return deadline | 30 days after tenancy ends |
| Itemized statement | Required with any deductions |
| Interest on deposit | Not required |
Keep dated photos of the unit at move-in and move-out, and send any communications about the deposit by certified mail so you have a paper trail if the return is delayed or disputed.
When can a landlord enter? Notice rules
New Hampshire law requires a landlord to obtain the tenant's prior consent before entering a residential rental unit. There is no fixed statutory timeframe such as 24 or 48 hours for ordinary visits, which makes "prior consent" the operative standard: the landlord and tenant should agree in advance on a date and time. One specific exception exists: if a landlord needs access to conduct a bed-bug inspection, 48 hours' advance notice is required by statute.
Emergency situations are treated differently. A landlord may enter without prior consent when there is an immediate threat to health or safety, such as a burst pipe, a gas leak, or a structural emergency. The emergency exception is narrow and should not be used as a routine workaround for the consent requirement.
For any non-emergency entry, tenants should insist on advance notice and should put requests and approvals in writing. If a landlord persistently enters without consent, that may constitute unlawful entry under RSA 540-A, which gives tenants the right to seek an injunction and damages.
Ending a lease: notice to vacate
To end a month-to-month tenancy in New Hampshire, either the landlord or the tenant must provide 30 days' written notice. The 30-day period typically runs from the next rental due date after notice is given, so the practical lead time may be slightly longer than a calendar month.
New Hampshire adds an important limitation for landlords: even with 30 days' notice, a landlord can only terminate a tenancy for one of the statutory causes listed in RSA 540. Those causes include nonpayment of rent, lease violations, the landlord's legitimate need to use the property, and certain other enumerated grounds. A landlord cannot simply give 30 days' notice and force a tenant out without a qualifying reason. This gives tenants in New Hampshire somewhat stronger protection against no-cause evictions than tenants in many other states.
If a landlord seeks to evict for nonpayment or a lease violation, the process starts with the appropriate statutory notice. See the New Hampshire eviction notice page for notice periods and procedures, or visit the eviction notice hub for a general overview.
Repairs and the warranty of habitability
New Hampshire recognizes an implied warranty of habitability under RSA 540:13-d. This means every residential rental must be fit for human habitation: it must have working heat, running water, sanitation, structurally sound walls and roof, and functioning electrical systems. Landlords must maintain these conditions throughout the tenancy, not just at move-in.
If a landlord fails to make a required repair after receiving written notice, New Hampshire tenants have a few potential remedies. Rent withholding is recognized as an affirmative defense in eviction proceedings under New Hampshire case law. This means a tenant who withholds rent because of serious habitability defects can raise those defects as a defense if the landlord tries to evict for nonpayment. It is not a blanket right to stop paying rent, and using it carries real risk: the tenant needs solid documentation of the problem and proof that notice was given to the landlord before the withholding started.
Before withholding rent, a tenant should put every repair request in writing, keep copies, and consider consulting a tenant-rights organization or attorney. In serious cases, tenants can also contact the local code enforcement office to request an official inspection and written notice of violations.
Rent, late fees, and rent control
New Hampshire does not have a statutory cap on late fees. Landlords and tenants are free to agree on a late-fee amount in the lease, and courts generally enforce those provisions. There is also no required grace period before a late fee can be charged, though many leases build in a short window (commonly three to five days). Read your lease carefully to know exactly when your rent is considered late.
For rent increases, New Hampshire law does not require any particular advance notice period beyond what the lease itself provides, or reasonable notice for month-to-month tenancies. A landlord raising rent on a month-to-month tenant would typically need to give at least 30 days' notice since raising the rent changes a material term of the tenancy.
New Hampshire has no statewide rent control law, and there are no active local rent-control ordinances in the state. Local governments in New Hampshire are generally preempted from adopting rent regulation. This means landlords can raise rent as much as they choose (with proper notice to end the current tenancy terms), subject only to any limits in a fixed-term lease.
If you have a landlord-tenant dispute in New Hampshire
Most landlord-tenant disputes in New Hampshire can be resolved through clear communication and documentation, but knowing your options matters when things escalate.
Start by putting everything in writing. Whether you are requesting a repair, disputing a charge, or giving notice, a written record protects you. Send important communications by email or certified mail and keep copies.
For deposit disputes involving amounts up to $10,000, New Hampshire's small claims court (part of the Circuit Court's District Division) is the practical venue. Filing fees are modest and you do not need an attorney. Bring dated photos, the lease, move-in and move-out checklists, and all written correspondence.
If a landlord is entering without consent or retaliating against you for complaining about conditions, RSA 540-A gives you the right to seek an injunction and damages in court. The New Hampshire Housing Finance Authority (NHHFA) maintains tenant resources, and New Hampshire Legal Assistance (NHLA) provides free civil legal aid for qualifying tenants.
For complex disputes or situations involving potential eviction, consulting a licensed attorney is the most reliable next step. Legal aid organizations can often advise on whether you have a strong defense before any court date.
This article is general legal information, not legal advice. Landlord-tenant rules vary by state and city and change, and some cities add their own ordinances. For advice about a specific situation, consult a licensed attorney or your state housing agency.

Frequently Asked Questions
How long does a landlord have to return my deposit in New Hampshire?
New Hampshire landlords must return the security deposit, plus a written itemized statement of any deductions, within 30 days after the tenancy ends. If the landlord misses this deadline, you can sue in small claims court and may recover double the wrongfully withheld amount.
What is the maximum security deposit in New Hampshire?
The cap is 1 month's rent or $100, whichever is greater. For most tenants paying current market rent, this works out to one month's rent. Anything collected above that limit is unlawful under RSA 540-A:6.
How much notice must a landlord give to enter in New Hampshire?
New Hampshire requires the tenant's prior consent before a landlord enters. There is no fixed number of hours for ordinary visits; the landlord and tenant must agree in advance. For bed-bug inspections specifically, 48 hours' advance notice is required. Emergencies allow entry without prior consent.
How much notice is needed to end a month-to-month lease in New Hampshire?
Either party must give 30 days' written notice. However, landlords in New Hampshire also need a statutory reason (such as nonpayment, a lease violation, or owner use) to terminate a tenancy. A landlord cannot end a tenancy for no cause even with 30 days' notice.
Can a landlord raise rent in New Hampshire?
Yes. New Hampshire has no statewide rent control and no local rent-control ordinances. Landlords can raise rent, but must give at least 30 days' notice to change the terms of a month-to-month tenancy. A fixed-term lease cannot be changed mid-term without the tenant's agreement.
Can I withhold rent for repairs in New Hampshire?
New Hampshire recognizes rent withholding as a defense in eviction proceedings when a landlord has failed to maintain habitable conditions after written notice. This is not a risk-free remedy: document every repair request in writing, keep proof you notified the landlord, and consider consulting an attorney before withholding rent.
