Most towns allow tiny homes as accessory dwelling units (ADUs), but restrictions on size, setbacks, and foundation types vary widely. Some communities permit them with variances, while others ban them entirely unless zoned specifically. Checking with your local planning department is essential before breaking ground.

Understanding Zoning and Building Codes

Massachusetts zoning laws are enforced at the town level, so rules differ significantly between cities and rural areas. Many suburban towns classify tiny houses under residential zoning but impose strict limits: maximum square footage (typically under 500 sq ft), minimum lot size, and requirements for permanent foundations or trailers. Electrical, plumbing, and heating systems must meet state building codes. Contacting the local building official early helps avoid costly delays or legal issues.
