Tiny home rules in Belchertown, MA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
The Massachusetts State Building Code, adopted under MGL Chapter 143, establishes uniform statewide minimum construction standards for dwellings including tiny homes, with municipalities prohibited from adopting weaker requirements.
Under MGL Chapter 143, Section 95, the Board of Building Regulations and Standards adopts a uniform State Building Code (780 CMR) that applies in all 351 cities and towns.

Tiny homes on permanent foundations must meet 780 CMR; tiny houses on wheels are regulated as recreational vehicles under MGL Chapter 140, Section 32A and cannot be used as permanent dwellings except in licensed recreational vehicle parks.
Building Code violations under MGL Chapter 143, Section 94 carry fines up to $1,000 per day, plus stop-work orders and potential criminal penalties for repeat or willful violations.
