County subdivisions not defined at a glance

Zoning & raw-land occupancy

Varies locallyMassachusetts General Laws Chapter 40A lets each city and town adopt its own zoning bylaw or ordinance; the state only limits what towns can regulate (e.g., they can't override state building code construction standards). Raw-land use rules vary completely by town. source

Dwellings, tiny homes & RVs

Varies locallyThe state building code (780 CMR, based on the IRC) includes Appendix AQ for tiny houses 400 sq ft or less, giving them a compliance path; RV/tiny-house-on-wheels occupancy as a permanent residence is decided by local zoning departments, not the state.

Building permits & codes

Restricted780 CMR is the statewide building code, and MGL Chapter 142A generally requires a registered contractor, though homeowners can seek an owner-builder exemption from their local Building Official. Permits are issued and enforced locally. source

Septic & composting toilets

RestrictedTitle 5 (310 CMR 15.000), administered by MassDEP, governs on-site sewage system siting, construction, and maintenance statewide; composting toilets are approved for general use but require a Disposal System Construction Permit from the local Board of Health. source

Greywater reuse

RestrictedGreywater discharge is regulated within Title 5 and generally still requires a septic tank and soil absorption system meeting state design standards unless a variance for an alternative technology is approved through the local Board of Health and MassDEP's regional office. source

Rainwater harvesting

Unclear - verifyNo dedicated state statute setting rainwater harvesting capacity limits or permits was found; the state Uniform Plumbing Code (248 CMR 10) governs any connections into household plumbing systems generally. Confirm with your town for any local health rules. source

Private wells & water rights

Varies locallyLocal Boards of Health hold primary jurisdiction over private well siting, construction, and water quality under MGL Chapter 111, Section 122; the state's role is limited to requiring that only Massachusetts Registered Well Drillers install wells. source

Living disconnected from utilities

Unclear - verifyNo state statute explicitly bans disconnecting from grid electricity or municipal water/sewer; in practice, local building departments typically require an approved water supply and Title 5-compliant wastewater system before issuing occupancy approval, making this a town-level determination. Not confirmed as a state-level rule either way.
