Nashua's Home Business: The Rules That Matter

Every city handles home business a little differently. In Nashua, New Hampshire, there are 4 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 & Home Occupation Permits

Nashua allows home-based businesses as accessory residential uses citywide, but minor home occupations need only an administrative certificate while major ones require a Zoning Board special exception under strict size and employee limits.

Key details: Minor home occupation limit: 20% of floor area or 200 sq ft. Major home occupation limit: 30% of floor area or 300 sq ft. Minor approval: Administrative Officer certificate. Major approval: Zoning Board special exception. Sign limit: One 2-sq-ft nonilluminated sign.

Operating a home occupation without the required certificate of use and occupancy, or a major home occupation without a Zoning Board special exception, is a zoning violation subject to enforcement action.

Customer Traffic Restrictions

Nashua caps customer, vendor and delivery visits to a minor home-based business at an average of three per week, keeping it 'infrequent' enough to stay unnoticed by neighbors.

Key details: Minor occupation limit: 3 visits/week, average. Governing rule: Zoning Ordinance § 190-47A(6). Approval needed: Certificate of use and occupancy. Over the limit: Requires ZBA special exception. General penalty: Up to $1,000/day, § 1-12.

Exceeding the three-visits-per-week average without a Zoning Board special exception risks denial or revocation of the certificate of use and occupancy, plus the City's general penalty of up to $1,000 per day under Code § 1-12.

Home Daycare

Nashua allows child day-care in a home as a by-right accessory use if state Health and Human Services licensing rules are met, per Land Use Code § 190-36.

Key details: Status: By-right accessory use in dwellings. Governing code: He-C 4002 (state licensing rule). State law tie-in: RSA 170-E applies. Zoning approval needed: None, if licensed.

Operating without meeting He-C 4002 licensing requirements or RSA 170-E can bring state Health and Human Services enforcement action, including denial or revocation of the child care license; zoning-side noncompliance is enforced by the City's Code Enforcement Department under the Land Use Code's general violation provisions.

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

Signage Rules

Home occupation signs in Nashua are capped at two square feet, must stay non-illuminated, and only one sign per property is allowed under the city's zoning ordinance.

Key details: Max sign area: 2 square feet. Illumination: not permitted. Signs allowed per premises: one. Other advertising: prohibited on premises. Applies to: minor and major home occupations.

Putting up a sign larger than two square feet, illuminated, or a second one without a land use permit violates § 190-47C and § 190-128A, and can trigger revocation of the home occupation certificate or special exception under § 190-127.

The Bottom Line

Nashua's home business rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Nashua is broadly strict or permissive.
