Showing ordinances that apply to Groton, MA
Groton is an unincorporated community (population 1,353) in Middlesex County, Massachusetts. Because Groton is not an incorporated city, it does not have its own municipal code. Instead, Middlesex County ordinances apply directly to properties here. The livestock rules below are the ones that govern your area.
Livestock in Middlesex County is restricted to rural and agricultural zones. Urban and inner-suburban communities prohibit horses, goats, pigs, and cattle; western Middlesex permits them on large lots.
Livestock keeping in Middlesex County is governed by local zoning bylaws and MGL c.40A (zoning), with statewide agricultural protections under MGL c.40 s.1A (Right to Farm). Inner Middlesex cities (Cambridge, Somerville, Medford, Malden, Everett) prohibit all livestock other than limited backyard chickens. Middle-ring suburbs (Newton, Arlington, Lexington, Belmont) likewise prohibit horses and livestock in residential zones. Western Middlesex communities including Concord, Carlisle, Acton, Boxborough, Groton, Pepperell, Townsend, Ashby, and Dunstable allow livestock on agriculturally zoned parcels, typically 2+ acres. Horses require 2-acre minimums with 50-100 foot setbacks for stables and manure storage. Goats, sheep, and small cattle follow similar rules. Pigs are generally restricted to active farming operations. Massachusetts Right to Farm protections shield pre-existing farms from nuisance complaints even as residential development encroaches, a major issue in Concord and Carlisle.
