Chelsea, MA Home Business: Customer Traffic Restrictions (2026)

Section 34-50(f)(1) permits a home occupation or professional office in the R1, R2, and NHR residential districts only if it does not change the residential character of the building or neighborhood, is operated by a resident with not more than one employee, occupies no more than 25 percent of the habitable space as defined in the state building code, has no exterior storage of materials or equipment, displays no signs or products visible from the street, and involves no retail sale of merchandise on the premises.

Only one home occupation is allowed per dwelling unit. The definitions article, Section 34-241, sharpens the customer-traffic boundary directly: a home occupation is an accessory use carried on entirely within the dwelling unit and incidental to its residential use, and the term expressly excludes barbershops, commercial stables or kennels, teaching of more than three pupils simultaneously, and, for musical instruction, more than one pupil at a time. That teaching cap is the code's clearest numeric limit on client volume for an in-home business: a tutor or instructor can work with up to three students at once (or one music student) and still qualify as an accessory home occupation, but a fourth simultaneous pupil, or a second simultaneous music student, converts the activity into a use the residential districts do not permit at all, since it falls outside the home-occupation definition entirely. m. Monday through Saturday, underscoring how tightly the code manages walk-in or client-facing traffic at a residence.
