Fire Regulations in Nashua, NH: What Residents Actually Need to Know

If you live in Nashua or are thinking about moving there, fire regulations are one of those things you probably won't think about until they affect you directly. Nashua has 8 specific rules on the books covering different aspects of fire regulations, and some of them might surprise you.

Outdoor Burning

All open burning in Nashua requires both a city permit from Nashua Fire Rescue under City Code § 110-2 (Chapter 110, Burning, Open) and a written forest-fire-warden permit under RSA 227-L:17 (Woodland Fire Control). The City Forest Fire Warden is the Nashua Fire Chief. Permits are free and issued through nashuanh.burnpermits.com in three categories: Category 1 (minimum 25-foot setback from any structure, applied for entirely online), Category 2 and Category 3 (minimum 50-foot setback, require a site visit). Burning is allowed between 5:00 p.m. and midnight, weather permitting. No permit is required only when the ground is completely covered with snow.

Key details: City Permit Cite: Nashua Code § 110-2 (Chapter 110). State Permit Cite: RSA 227-L:17 (Forest Fire Warden). Permit Cost: Free. Apply Online: nashuanh.burnpermits.com. Permitted Hours: 5:00 p.m.-midnight (weather permitting).

Open burning without the required permits violates Nashua City Code § 110-2 and RSA 227-L:17. RSA 227-L:17 imposes strict liability: any person who kindles a fire without a required permit is liable for all damages caused and for all expenses incurred in extinguishing the fire, plus statutory fines under RSA 227-L. Nashua Fire Rescue and the City Forest Fire Warden enforce. Nashua Fire Marshal's Office: (603) 594-3650; for an active fire call 911.

Compared to other cities, Nashua takes a harder line on outdoor burning. The enforcement and penalty structure reflects that.

Wildfire Zones

Nashua is a built-out southern New Hampshire suburban city with no formally mapped wildland-urban interface (WUI) zones and no stand-alone wildfire hazard ordinance. Wildfire risk inside the city is generally low compared with northern New Hampshire forest country, but vegetation along Mine Falls Park, the Nashua River corridor, the Pennichuck Brook watershed, and the Merrimack River edge can carry fire in drought conditions. State-level wildfire authority comes from RSA Chapter 227-L (Woodland Fire Control), administered by the NH Division of Forests and Lands, with the Nashua Fire Chief serving as the City Forest Fire Warden. The NH Forest Fire Danger ranking (Class I Low through Class V Extreme) can trigger statewide or regional burn suspensions independent of city permits.

Key details: Formal WUI Map: None. City Wildfire Ordinance: None (relies on state law). State Authority: RSA Chapter 227-L (Woodland Fire Control). Local Forest Fire Warden: Nashua Fire Chief. Fire Danger Suspensions: Class V Extreme = burning suspended.

Wildfire-related rules in Nashua are enforced under (1) Nashua City Code Chapters 110 and 156 by Nashua Fire Rescue, (2) RSA 227-L by the City Forest Fire Warden (Fire Chief) and the NH Division of Forests and Lands, and (3) the State Fire Code (NFPA 1, 2021 ed.) adopted under RSA 153. Burning during a Class V Extreme fire-danger day, even with a valid permit, violates state policy. Nashua Fire Marshal's Office: (603) 594-3650; NH Division of Forests and Lands forest protection: (603) 271-2217.

If you are coming from a city with tighter rules, you will find Nashua gives residents more flexibility on wildfire zones.

Fire Pit Rules

Backyard fire pits, chimineas, fire bowls, and any open burning of solid fuel materials (other than charcoal) in Nashua require a burn permit from Nashua Fire Rescue under Chapter 110 (Burning, Open) of the City Code and RSA 227-L:17. Permits are issued free at nashuanh.burnpermits.com. Category 1 permits cover compliant campfires with a minimum 25-foot setback from any structure; Categories 2 and 3 require a 50-foot setback and a site visit. Burning is allowed only between 5:00 p.m. and midnight, weather permitting, and only when the ground is not snow-covered without a permit. The 2021 edition of NFPA 1 (Uniform Fire Code), adopted statewide effective August 13, 2024 under RSA 153, applies as the enforcement baseline.

Key details: Permit Required: Yes (Nashua Code § 110-2 + RSA 227-L:17). Apply Online: nashuanh.burnpermits.com (free). Category 1 Setback: Min. 25 ft from any structure. Category 2/3 Setback: Min. 50 ft from any structure (site visit). Permitted Hours: 5:00 p.m. to midnight, weather permitting.

Open burning without a permit violates Nashua City Code § 110-2 and RSA 227-L:17 and is enforced by Nashua Fire Rescue and the City Forest Fire Warden. RSA 227-L:17 makes any person who kindles a fire without a required permit liable for all damages caused and for all expenses incurred in extinguishing the fire, plus state-law fines. Nashua Fire Marshal's Office: (603) 594-3650. For fire emergencies call 911.

This is not one of those rules that cities tend to ignore. Nashua actively enforces its fire pit rules requirements.

Fireworks

Nashua City Code Chapter 160 (Fireworks) prohibits the sale, purchase, possession, use, or explosion of any fireworks without a permit issued in accordance with RSA 160-B and RSA 160-C. The ordinance further states that 'there shall be no permits granted, except to the City of Nashua for programs and displays under its control, for the sale, purchase, possession, use or explosion of Class C fireworks' - the consumer (permissible) fireworks otherwise allowed elsewhere in New Hampshire. The Fire Marshal may grant a permit for professional fireworks displays when proper safety is provided. For permitted displays, only color shells, cakes, and whistlers may be used, discharged, or displayed after 10:00 p.m.; salute, reports, and thunder-shell fireworks are prohibited between 10:00 p.m. and 8:00 a.m. Nashua is on the NH State Fire Marshal's Community Restrictions List as a city that does not allow permissible (consumer) fireworks.

Key details: City Ban: All Class C / consumer fireworks prohibited (Ch. 160). State Authority for Local Ban: RSA 160-C:6 (Local Option). Display Permit: Fire Marshal may issue (proper safety required). Time Limit on Displays: No salute / reports / thunder shells 10 p.m.-8 a.m.. After 10 p.m. (permitted shows): Color shells, cakes, whistlers only.

Possession, use, or discharge of consumer (Class C / permissible) fireworks anywhere in Nashua violates Chapter 160 of the Nashua City Code and is enforced by the Nashua Fire Marshal's Office and Nashua Police Department. Violators face penalties under RSA 160-B and RSA 160-C plus the City Code general penalty under § 1-12. Display-fireworks violations and unlicensed pyrotechnic operations can trigger separate criminal penalties under RSA 160-B. Nashua Fire Marshal's Office: (603) 594-3650; Nashua Police non-emergency: (603) 594-3500.

This is one of the stricter rules in Nashua's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Brush Clearance

Nashua does not have a stand-alone defensible-space or vegetation-clearance ordinance. Brush and combustible-vegetation hazards are addressed through the New Hampshire State Fire Code (NFPA 1, 2021 edition, adopted statewide effective August 13, 2024 under RSA 153) - including NFPA 1 provisions on outdoor accumulations of combustible waste - and through RSA 227-L (Woodland Fire Control), administered by the NH Division of Forests and Lands, which authorizes town forest fire wardens (the Nashua Fire Chief and designees) to require abatement of fire hazards on land adjacent to forest. Open burning of brush requires a Chapter 110 permit and a written RSA 227-L:17 permit from the forest fire warden.

Key details: Stand-Alone Brush Ordinance: None. State Fire Code: NFPA 1 / NFPA 101, 2021 ed. (RSA 153). Forest Fire Authority: RSA 227-L (Woodland Fire Control). Local Burn Permit: Required (Nashua Code Ch. 110). Setback for Burning: 25 ft (Cat 1) / 50 ft (Cat 2-3).

Combustible-waste accumulations and open-burning violations are enforced by Nashua Fire Rescue under City Code Chapter 110 (Burning, Open) and the State Fire Code (NFPA 1, 2021 ed.) adopted under RSA 153. Forest-fire-warden orders under RSA 227-L are enforced by the City Forest Fire Warden (Fire Chief) and the NH Division of Forests and Lands. Nashua Fire Marshal's Office: (603) 594-3650.

Smoke Detectors

Smoke and carbon monoxide alarms in Nashua dwellings are required under New Hampshire RSA 153:10-a (Automatic Fire Warning Devices and Carbon Monoxide Detection Devices in Dwellings), the New Hampshire State Fire Code (NFPA 1, 2021 ed.; NFPA 101, 2021 ed.; NFPA 72 National Fire Alarm and Signaling Code), and the New Hampshire State Building Code adoption of the 2021 IRC (R314 Smoke Alarms, R315 Carbon Monoxide Alarms) under RSA Chapter 155-A. Smoke alarms are required in every sleeping room, outside each sleeping area, and on every level. Carbon monoxide alarms are required in any dwelling unit with an attached garage or any fuel-burning appliance. Owners are responsible for installation and maintenance in rental units.

Key details: Smoke / CO Statute: RSA 153:10-a. State Fire Code: NFPA 1 + NFPA 101 + NFPA 72 (2021 ed.). Building Code: 2021 IRC R314 / R315 (RSA 155-A). Smoke Alarm Locations: Every sleeping room + outside each + each level. CO Alarm Trigger: Attached garage or any fuel-burning appliance.

Missing, inoperative, or non-compliant smoke or CO alarms in a Nashua rental dwelling violate RSA 153:10-a and the New Hampshire State Fire Code adopted under RSA 153. Nashua Fire Rescue (Fire Marshal's Office) and the City's Building Department enforce through Code Enforcement inspections; landlords face state-law penalties plus orders to correct. Nashua Fire Marshal's Office: (603) 594-3650; Nashua Building Department: (603) 589-3030.

This is not one of those rules that cities tend to ignore. Nashua actively enforces its smoke detectors requirements.

Backyard Fires

A backyard fire in Nashua - including any fire pit, chiminea, burn barrel, or campfire fueled by anything other than charcoal - requires both a city permit from Nashua Fire Rescue under City Code § 110-2 (Chapter 110, Burning, Open) and a written forest-fire-warden permit under RSA 227-L:17 (Woodland Fire Control). Permits are free through nashuanh.burnpermits.com and come in three categories with structure setbacks of 25 feet (Category 1) or 50 feet (Categories 2 and 3). Burning is allowed only between 5:00 p.m. and midnight, weather permitting. Propane, natural gas, and charcoal cooking grills are exempt from the open-burning permit requirement. The State Fire Code (NFPA 1, 2021 ed., adopted August 13, 2024) supplies the underlying life-safety standard.

Key details: Permit Required: Yes (Nashua § 110-2 + RSA 227-L:17). Cost: Free (nashuanh.burnpermits.com). Setback (Cat 1 fire pit): Min. 25 ft from any structure. Setback (Cat 2 / 3): Min. 50 ft + site visit. Hours: 5:00 p.m.-midnight (weather permitting).

Backyard burning without the required permits violates Nashua City Code § 110-2 and RSA 227-L:17. RSA 227-L:17 imposes strict liability: the person who kindles a fire without a required permit is liable for all damages caused and for all expenses incurred in extinguishing the fire. Nashua Fire Rescue may order an unsafe fire extinguished on the spot. Nashua Fire Marshal's Office: (603) 594-3650; for an active fire call 911.

Compared to other cities, Nashua takes a harder line on backyard fires. The enforcement and penalty structure reflects that.

Propane Storage

Propane and LP-gas storage and use in Nashua are governed by the New Hampshire State Fire Code, which adopts NFPA 1 (Uniform Fire Code), 2021 edition, effective August 13, 2024 under RSA 153. NFPA 1 incorporates NFPA 58 (Liquefied Petroleum Gas Code) as the technical standard for LP-gas container storage, dispensing, transportation, and use. Residential consumer cylinders (typically 20-lb grill tanks) are allowed at one- and two-family dwellings with manufacturer-recommended clearances. Storage in public buildings is limited to 1-lb cylinders with a total of 200 lb of propane. Bulk and commercial installations require fire-prevention permits from the Nashua Fire Marshal under City Code Chapter 156 (Fire Prevention) and follow the separation distances in NFPA 58. Cooking grills on combustible balconies in multi-family buildings are restricted by NFPA 1.

Key details: State Fire Code: NFPA 1, 2021 ed. (RSA 153, eff. Aug 13, 2024). Technical Standard: NFPA 58 Liquefied Petroleum Gas Code. Public Building Storage Cap: 1-lb cylinders, 200 lb total propane. Cylinder Setback (2 exits): 5 ft from building opening. Cylinder Setback (1 exit): 10 ft from building opening.

Commercial installations without required permits are subject to stop-work orders and civil penalties; property managers can be cited for grills or cylinders stored on combustible balconies in multi-family buildings under NFPA 1. Nashua Fire Marshal's Office: (603) 594-3650.
