Newton, MA Home Business: Signage Rules (2026)

Sec. 3 permits one home business per dwelling unit as an accessory use in residence districts, subject to conditions listed in Sec. 3(B)(1). The business must be clearly incidental to the residential use, occupy no more than 30 percent of the dwelling's ground floor area (or of an apartment's gross floor area in a multifamily building), employ no more than one nonresident in a secretarial role (two for a physician or dentist), and serve no more than three customers, pupils or patients at a time.

Subsection (f) governs signage directly: there can be no exterior display or storage of merchandise, and no exterior indication of the business other than one non-illuminated identification sign capped at 2 square feet. This tracks the general dwelling-sign allowance in Sec. 6(A)(4), which lets a plain dwelling identification sign reach only 1 square foot but raises the cap to 2 square feet where a permitted accessory home business exists. The business also cannot generate noise, vibration, glare, fumes, odors, electrical interference or traffic beyond what is normal for the neighborhood, and off-street parking must be provided at one stall per 200 square feet of home-business floor area.
