New Hampshire compliance obligations
New Hampshire landlords commonly track 5 state and local compliance obligations, each listed below with its schedule, its sources, and the date we last verified it. Among them: file New Hampshire LLC annual report by April 1, return security deposit and itemized list within 30 days after tenancy ends, and review interest owed on security deposits held a year or longer.
File New Hampshire LLC annual report by April 1
If your rental is held in an LLC or corporation registered in New Hampshire, filing its annual report with the Secretary of State by April 1 avoids a $50 late fee on top of the $100 filing fee, and missed reports can lead to administrative dissolution.

Pay first-half property tax bill where your town bills twice a year
In New Hampshire towns that bill property tax twice a year, the first installment is usually due around July 1, and paying by the date printed on your town's bill avoids interest that runs at 8 percent a year on any late balance.

Return security deposit and itemized list within 30 days after tenancy ends
Returning the security deposit and any interest owed within 30 days after the tenancy ends, with a written itemized list of any deductions and receipts or estimates for repair charges, protects New Hampshire landlords covered by the deposit law from liability of up to twice the deposit plus interest.

Review interest owed on security deposits held a year or longer
Unless you rent only one single-family home and own no other rental property, or rent units in an owner-occupied building of five units or less (units occupied by someone 60 or older stay covered), New Hampshire requires paying interest on a security deposit held a year or longer at the regular savings rate of the New Hampshire bank, savings and loan, or credit union holding it, so a yearly review of each deposit account keeps that interest ready to pay at move-out or when a tenant asks for it.

Verify smoke and CO alarms per NH fire code
New Hampshire requires every rental unit to have smoke alarms and, where the unit has an attached garage or any appliance or device that burns fuel, carbon monoxide alarms, and makes the owner responsible for keeping them in working order, so a yearly test of every alarm (replacing any smoke alarm older than 10 years, as the US Fire Administration advises) keeps each unit compliant and its occupants protected.

Seasonal maintenance for New Hampshire
Landlords in New Hampshire plan upkeep around a cold climate: this guide lists 7 seasonal maintenance items for New Hampshire in calendar order, each with its timing and the date we last verified it. Among them: monitor roof snow load and check for ice dams, test sump pump and clear foundation drainage before snowmelt, and smoke and CO detector seasonal test.
Monitor roof snow load and check for ice dams
Midwinter checks for ice damming and heavy roof snow catch structural stress and meltwater leaks before interior damage appears.

Test sump pump and clear foundation drainage before snowmelt
Snow cover across most of New Hampshire melts during March and April, and meltwater and spring rain can raise groundwater and send runoff toward the foundation, so testing the sump pump and clearing downspout outlets and drainage paths in early March helps keep water out of the basement.

Smoke and CO detector seasonal test
An annual full test of smoke and CO detectors (beyond battery swaps) confirms every alarm actually sounds.

Spring thaw inspection: roof and foundation
Freeze-thaw cycles crack roofs and foundations; a spring inspection catches winter damage early.
Around April · Verified before August 2026
Winterize exterior plumbing and irrigation before first freeze
Hard freezes usually reach New Hampshire's North Country around the end of September and Concord by mid-October, and water left in hoses, hose bibs, irrigation lines, or plumbing in unheated spaces expands as it freezes and can crack the spigot or the pipe behind it, so draining and shutting off these lines by mid-September prevents burst pipes and water damage.

Furnace inspection before heating season
A pre-season furnace inspection prevents mid-winter heating failures and carbon monoxide risk.
