Nashua's Home Business: The Rules That Matter

Every city handles home business a little differently. In Nashua, New Hampshire, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Zoning Restrictions

Nashua Land Use Code Sec. 190-20 (Article VI Supplemental Use Regulations) permits home occupations in residential districts in two tiers. A Minor Home Occupation allows no nonresident employees and up to 20 percent of dwelling floor area or 200 sq ft (whichever is less), reviewed administratively by the Administrative Officer. A Major Home Occupation allows 1 nonresident employee and up to 30 percent of floor area or 300 sq ft (whichever is less), except child day care which may use up to 420 sq ft, and requires Zoning Board of Adjustment approval as a special exception.

Key details: Code Reference: Nashua Land Use Code Sec. 190-20. Minor Home Occupation Sq Ft Cap: 20% of dwelling or 200 sq ft (lesser). Minor Nonresident Employees: 0. Major Home Occupation Sq Ft Cap: 30% or 300 sq ft (420 sq ft for day care). Major Nonresident Employees: 1 maximum.

Operating a home occupation without the required Minor permit or Major Special Exception is a violation of Sec. 190-20 enforceable by the Administrative Officer under Sec. 190-15 and Article XV. Remedies include a cease-and-desist order, civil penalties under NH RSA 676:17 of up to $275 per day for the first offense and $550 per day for subsequent offenses, and equitable relief in Hillsborough County Superior Court.

Signage Rules

Nashua Land Use Code Sec. 190-20 limits home occupation signage to a single non-illuminated sign of 2 sq ft or less identifying only the occupant's name and address. Window signs, A-frames, banners, and freestanding monument signs advertising the home business are prohibited in all residential districts. Article X (Sec. 190-200 et seq. Signs) sets a separate sign permit requirement through the Department of Building Safety.

Key details: Code Reference: Sec. 190-20 + Article X (Sec. 190-200). Permitted Sign: 1 non-illuminated, 2 sq ft max. Sign Content: Occupant name and address only. Illumination: Prohibited. Sign Permit: Required (Dept of Building Safety).

Sign violations under Sec. 190-20 and Article X are enforced by the Administrative Officer and Department of Building Safety with a cease-and-desist order requiring sign removal, civil penalties under NH RSA 676:17 of up to $275 per day for the first offense and $550 per day for subsequent offenses, and equitable relief through Hillsborough County Superior Court. Installing a sign without a permit is also a separate violation of Article X.

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.

Home Daycare

Nashua Land Use Code Sec. 190-20 expressly addresses child day-care facilities as Major Home Occupations, permitting up to 420 sq ft of dwelling floor area (versus 300 sq ft for other Major occupations). NH RSA 170-E and N.H. Admin. Code He-C 4002 license Family Child Care Homes (FCCH) for up to 6 unrelated children plus up to 3 school-age children before/after school. A NH DHHS Child Care Licensing license is required for care of 4 or more children, including the operator's own.

Key details: Local Zoning Reference: Nashua Sec. 190-20 (Major Home Occupation). Day Care Floor Area Cap: 420 sq ft (Sec. 190-20). State Statute: NH RSA 170-E. Family Child Care Home Capacity: 6 children + up to 3 school-age. License Threshold: Required for 4+ children incl. own under 5.

Operating an unlicensed child care arrangement above the RSA 170-E threshold is a violation of RSA 170-E:32 subject to civil penalties and a cease-and-desist order from NH DHHS. Nashua zoning violations (operating a child day-care home without a Major Special Exception, or exceeding 420 sq ft) are enforced by the Administrative Officer with civil penalties under NH RSA 676:17 of up to $275 per day first offense and $550 per day subsequent, plus revocation of the Special Exception.

Home Occupation Permits

Nashua requires every home occupation to obtain approval under Sec. 190-20 before operation begins. Minor Home Occupations file an application with the Administrative Officer (Department of Building Safety) and receive a Certificate of Use and Occupancy administratively. Major Home Occupations require a Special Exception from the Zoning Board of Adjustment under Sec. 190-180 with a public hearing. New Hampshire has no statewide municipal business license, but NH Secretary of State LLC/corporation filings and any trade-specific state licenses still apply.

Key details: Minor Permit Required: Yes — Administrative Officer Certificate of Use. Major Permit Required: Yes — ZBA Special Exception (public hearing). Major Application Fee: $200-$400 (current fee schedule). Minor Review Type: Administrative (no hearing). Major Review Type: Public hearing (RSA 676:7 notice).

Operating without an approved Certificate of Use (Minor) or Special Exception (Major) is a violation of Sec. 190-20 enforceable by the Administrative Officer under Sec. 190-15. Remedies include cease-and-desist orders, civil penalties under NH RSA 676:17 of up to $275 per day first offense and $550 per day subsequent, equitable relief in Hillsborough County Superior Court, and revocation of any existing approval.

Customer Traffic Restrictions

Nashua Land Use Code Sec. 190-20 requires home occupations not to significantly change the residential character of the property. Minor Home Occupations allow no nonresident employees and effectively limit on-site client traffic to occasional one-on-one visits. Major Home Occupations allow 1 nonresident employee and are subject to Zoning Board of Adjustment conditions on traffic, parking, and hours. Off-street parking standards in Sec. 190-160 require adequate driveway capacity to avoid spillover onto the street.

Key details: Code Reference: Nashua Sec. 190-20 + Sec. 190-160. Minor — Nonresident Employees: 0. Major — Nonresident Employees: 1 maximum. Residential Character Test: Required (Sec. 190-20). Off-Street Parking: Required for staff and clients (Sec. 190-160).

Excess customer traffic, parking spillover, or off-premises nuisance is enforced by the Nashua Administrative Officer under Sec. 190-15 and Article XV. Remedies include a cease-and-desist order, revocation of the Minor Certificate of Use or Major Special Exception, civil penalties under NH RSA 676:17 of up to $275 per day for the first offense and $550 per day subsequent, and equitable relief in Hillsborough County Superior Court.

Cottage Food Operations

New Hampshire RSA 143-A (Homestead Food Operations) authorizes Nashua residents to sell non-potentially hazardous homemade foods directly to consumers without a license up to $35,000 in gross annual sales. Above $35,000 or for wholesale/internet/mail order, a Class H Homestead Food License ($150) from NH DHHS is required. Allowed products: breads, cookies, jams, jellies, candies, fudge, dry mixes, pickles, fruit pies. Nashua Sec. 190-20 requires a Minor or Major Home Occupation approval in addition to the state food framework.

Key details: State Statute: NH RSA 143-A (Homestead Food Operations). Exempt Sales Cap: $35,000 annual gross. Class H License Fee: $150 annual. Allowed Products: Bread, cookies, jams, jellies, candies, dry mixes, pickles. Prohibited: Cream pies, custards, cheesecake, meat, dairy, sandwiches.

Selling unapproved (potentially hazardous) products, exceeding $35,000 without a Class H license, or selling to retailers without licensing is enforced by NH DHHS Food Protection with cease-and-desist orders, embargo of product, civil penalties under RSA 143-A:18, and revocation of a Class H license. Local Nashua zoning violations are enforced by the Administrative Officer with civil penalties under NH RSA 676:17 of up to $275 per day first offense and $550 per day subsequent.

The rules around cottage food operations in Nashua lean permissive, but that does not mean anything goes.
