New Hampshire Landlord-Tenant Law 2026: The Plain-English Guide

New Hampshire splits its rental law across two chapters: RSA 540 governs evictions and termination notices, while RSA 540-A covers prohibited practices and security deposits. The state's personality is distinctive: a $100-or-one-month's-rent deposit cap (whichever is greater), interest owed after one year, an itemized deposit return backed by receipts, and a nonpayment eviction process that gives tenants a genuine pay-and-stay right — but also preserves no-cause 30-day terminations on month-to-month tenancies. Paperwork precision is everything here; New Hampshire rewards landlords who document and punishes those who improvise.

Eviction in New Hampshire

Self-help is flatly illegal — no lockouts, no utility shutoffs, no seizing property (RSA 540-A:3, I–II). Every eviction runs through a written notice to quit followed by a possessory action in court, and the notice must state the reason with specificity (RSA 540:3, III). Vague notices die in court.

Repairs and habitability

Entry rights

New Hampshire doesn't pin a fixed number of hours to every entry — the standard is reasonable notice, adequate under the circumstances, at reasonable times, and the tenant may not willfully refuse access for necessary repairs or other lawful ownership functions (RSA 540-A:3, V). Two specifics to know:

Discrimination

The federal Fair Housing Act applies, and New Hampshire's law (RSA 354-A) adds age, marital status, and sexual orientation (with gender identity covered under the state's broader civil-rights framework). Practical traps: "ideal for a young professional" in an ad (age), different treatment of unmarried couples (marital status), and occupancy rules that hit families with children. One exemption to know: owner-occupied buildings with four or fewer units are exempt from most of RSA 354-A's housing provisions — but not from the ban on discriminatory advertising (RSA 354-A:13, RSA 354-A:10, VII). Screen every applicant with identical written criteria. Our fair housing guide covers what you can and can't ask.

Small-landlord practical tips

1. Master the 5-day move-in window. The signed receipt telling tenants to report needed repairs in writing within 5 days of occupancy is your best deposit defense — use it every time.

2. Every deduction needs a receipt. New Hampshire's itemization rule expects receipts, estimates, or invoices per line item. No receipt, no deduction — build the paper trail as work happens, not at move-out.

3. Track interest from day one. After month 12, every deposit accrues interest at the account's savings rate. A spreadsheet column now beats a courtroom argument later.

4. Follow the demand-then-notice sequence for nonpayment: written demand for rent first, then the 7-day notice to quit with the pay-plus-$15 language. Skipping the demand step or the statutory language voids the notice.

5. Calendar 30-day rent-increase notices — and keep at least one non-electronic rent payment option available, or you're violating the statute on day one.

The bottom line

New Hampshire is a paperwork state: receipt-backed deposit itemizations, signed receipts with 5-day repair-reporting language, interest after year one, specific-cause notices, and a genuine pay-and-stay right on the first three nonpayment notices per year. The upside is real too — no-cause 30-day terminations survive on month-to-month tenancies, and there's no rent control. Landlords who run tight documentation — receipts for everything, proper notice sequences, interest tracked — do fine here. Landlords who wing it get doubled.
