Oxford, MA Building Setbacks & Zoning: Setback Rules (2026)

Setback rules in Worcester County are entirely municipal because county government was abolished in 1998 and zoning is authorized by MGL c. 40A (the Zoning Act). The City of Worcester Zoning Ordinance (Article IV) divides residential zones into RS-7 (single-family, 7,000 sf minimum lot), RS-10, RG-5 (general residential), RL-7, and RL-10 districts, each with specific setback tables. Typical single-family (RS-7) requirements: 20-30 ft front setback, 10 ft side, 25 ft rear. Corner lots have increased side setbacks on the street-facing side. Accessory structures (detached garages, sheds under 200 sf) typically get reduced rear/side setbacks of 3-5 ft. Variances require a Zoning Board of Appeals hearing under MGL c. 40A §10 with proof of hardship (shape/topography/soil conditions of the lot). Eaves and gutters may project up to 2 ft into setbacks; open porches up to 10 ft. Fitchburg, Leominster, Gardner, Worcester suburban towns (Shrewsbury, Westborough, Northborough, Grafton, Holden, Auburn), and rural towns (Princeton, Sterling, Rutland, Paxton, Hardwick, Petersham, Barre) each have their own bylaws. Wetlands Protection Act (MGL c. 131 §40) and Rivers Protection Act impose additional setbacks within 100 ft of wetlands / 200 ft of perennial rivers.
