Amherst, NH

Hillsborough County does not require a short-term rental license. New Hampshire has no statewide STR registration program either. The only state-level requirement is collecting and remitting the New Hampshire Meals and Rooms (Rentals) Tax of 8.5 percent under RSA 78-A:6 on any rental of a residential unit for less than 185 consecutive days. Cities and towns within the county (Manchester, Nashua, Merrimack, etc.) regulate STRs through local zoning under RSA 674.

Hillsborough County imposes no short-term rental tax. New Hampshire's only statewide STR levy is the 8.5% Meals and Rooms (Rentals) Tax under RSA 78-A on stays of less than 185 consecutive days. New Hampshire has no state or local sales tax. Some municipalities may charge nominal local zoning, health, or fire-inspection fees.

Hillsborough County does not set short-term rental occupancy caps. New Hampshire has no statewide STR occupancy limit. Maximum occupancy is governed by the New Hampshire State Building Code (RSA 155-A) and State Fire Code (RSA 153, NFPA 1/101) based on bedrooms, exits, and life-safety provisions, plus any limits in a host municipality's zoning ordinance.

Hillsborough County does not regulate short-term rental parking. New Hampshire has no statewide STR parking standard. Parking requirements come from each city or town's zoning ordinance under RSA 674. Most Hillsborough County municipalities require off-street parking for residential uses; on-street parking is governed by local traffic ordinances under RSA 47:17.

Hillsborough County does not enforce a pool fence ordinance - barrier rules come from the New Hampshire State Building Code under RSA 155-A. New Hampshire has adopted the International Residential Code (IRC) with state amendments. Residential pool barriers follow IRC Appendix AG (Section AG105), which requires a barrier at least 48 inches high with no openings allowing a 4-inch sphere to pass and self-closing, self-latching gates. Permits are issued by each city or town building department.

Hillsborough County has no county-level fireworks ordinance. New Hampshire fireworks law is found at RSA 160-C. 'Permissible fireworks' (consumer fireworks except those banned by RSA 160-B:16) may be possessed and displayed by adults 21 or older on private property with the owner's written consent or in the owner's presence, unless the city or town has voted to prohibit them under RSA 160-C:6. Display fireworks require a state license, municipal permit, and federal permit.

Hillsborough County itself does not regulate Accessory Dwelling Units. Under New Hampshire's Home Rule structure (RSA Title LXIV), zoning and ADU regulation is handled by the individual cities and towns - Manchester, Nashua, Merrimack, Hudson, Milford, etc. New Hampshire's statewide ADU enabling law at RSA 674:71-73 requires every municipality with single-family zoning to permit at least one ADU per single-family lot as a matter of right.

Hillsborough County has no county-level noise ordinance. New Hampshire counties have no operational regulatory authority over municipal nuisance matters - cities and towns regulate under RSA 31:39 (town bylaws) and RSA 47:17 (city bylaws). Statewide, RSA 644:2, III(a) makes it disorderly conduct to make 'loud or unreasonable noises in a public place' that would disturb a person of average sensibilities. Local quiet hours vary by municipality - Manchester (Chapter 94) and Nashua (Chapter 201) each set their own nighttime limits.

Hillsborough County does not regulate fence height. Under New Hampshire's home rule structure (RSA Title LXIV), fence height is set by each municipality's zoning ordinance under RSA 674:16-21. Nashua's Land Use Code Section 190-44 generally caps residential fences at 7 feet (with up to 14 feet allowed adjacent to the F.E. Everett Turnpike, requiring a building permit above 7 feet). Manchester sets fence rules in Chapter 155 (Zoning) - check your specific zoning district. State law RSA 473:1 also governs partition fences between abutting parcels.

Hillsborough County does not enforce dog leash rules. New Hampshire RSA 466:30-a makes it 'unlawful for any dog to run at large' off the owner's premises, except when accompanied by the owner or custodian. RSA 466:1 requires every dog 4 months or older to be licensed annually by the town or city clerk. RSA 466:31 covers nuisance, menace, and vicious dogs. Manchester (Code Chapter 90, Section 90.12) and Nashua (Code Chapter 93) add municipal leash and licensing rules.

Hillsborough County does not administer floodplain rules - that authority lies with each city and town and the state. Communities including Manchester, Nashua, Merrimack, Hudson, Litchfield, Lyndeborough, Milford, and Mont Vernon participate in the FEMA National Flood Insurance Program (NFIP). Development in any FEMA Special Flood Hazard Area mapped on the Hillsborough County DFIRM (panel set 33011C) must comply with local floodplain ordinances. Wetland fill or dredge requires a state permit under RSA 482-A.
