Can I run a business from home in Hamilton, Massachusetts?
Yes. Hamilton allows a customary home occupation by right in its residential districts, run by someone who lives there, in the house or an accessory building. It must stay secondary to the home, with no more than 2 non-resident employees, no outdoor storage or display, no more than 2 commercial vehicles parked outside, and signs limited to 3 square feet.
| Approval | Allowed by right in R-1A, R-1B, RA (not in TC-BRC) [1] |
| Who can run it | A person residing on the premises [2] |
| Non-resident employees | No more than 2 [3] |
| Commercial vehicles parked outside | No more than 2 [4] |
| Sign size (residential districts) | Max 3 sq ft [5] |
| Site plan review | Not required for customary home occupations [6] |
Allowed by right
The Table of Use Regulations lists a "customary home occupation conducted in a Dwelling or Building accessory thereto by a person residing on the premises" as allowed by right (Y) in the R-1A, R-1B and RA districts and most Town Center sub-districts, but not in the Bay Road Civic sub-district [1]. Section 3.3.1 repeats that a resident may run the business in the house or an accessory building [2]. Customary home occupations are exempt from Planning Board site plan review [6].
Conditions
Section 3.3.2 requires that [3]:
- the business be clearly incidental and secondary to living there;
- no more than two people who don't live there be regularly employed on site;
- no offensive noise, vibration, smoke, dust, fumes, odors, heat, glare or unsightliness be produced;
- there be no public display of goods or wares.
There can also be no outdoor storage of materials or equipment, no more than two commercial vehicles parked outside, and nothing else outside that shows the business or changes the home's residential character [4].
Signs
Home occupation signs must follow Section 6.3. In residential districts, a sign can't exceed 3 square feet [5]. Permanent signs need a building permit, and illuminated signs must be off from 11 p.m. to 6 a.m. Signs in the Historic District also need a certificate of appropriateness.
What isn't allowed
Kennels, contractor's yards, storage of commercial landscaping equipment or materials, and commercial auto repair are prohibited as accessory uses in the residential districts. The bylaw doesn't set a limit on customer visits, but the parking and "no exterior indication" rules effectively limit them.

Massachusetts state rules for home businesses
Massachusetts has no general state law on home occupations. Whether you can run a business from home, and what limits apply (employees, signs, client visits, parking), is set by your town's zoning bylaw. State law does protect some home-based uses and add a few requirements:
- Family child care is protected: a licensed family child care home or large family child care home (licensed by the Department of Early Education and Care) is an allowed use everywhere. Towns may not prohibit or regulate it through zoning (M.G.L. c. 40A, §3). A family child care home serves up to 6 children under 16, counting the provider's own children who are cared for there.
- The "Dover Amendment" (also c. 40A, §3) bars zoning from prohibiting religious or nonprofit educational uses and child care facilities. Towns can still apply reasonable rules on bulk, height, setbacks, open space and parking. This mainly matters for institutions, not typical home offices.
- Business certificate ("DBA"): if you do business under any name other than your own legal name, you must file a business certificate with the city or town clerk where your office is located (M.G.L. c. 110, §5).
- Farm stands and agriculture get zoning protection only on qualifying farm parcels (generally 5+ acres, or 2+ acres with $1,000 per acre in yearly sales).
- State licensing for specific trades (cosmetology, food production, etc.) applies no matter where you work.
