Off-Grid Living in Belmont, Massachusetts
Belmont, Massachusetts is a densely built, fully sewered suburb whose zoning bylaw prohibits any use not specifically enumerated, leaving little to no room for off-grid living, tiny homes on wheels, or raw-land occupancy.

If you're dreaming of going off-grid in Belmont, Massachusetts, I have to be straight with you upfront: this is about the least likely place in the state to pull that off. Belmont is a dense, fully built-out, sewered inner suburb of Boston, and its Zoning By-Law (administered locally but grounded in Massachusetts General Law Chapter 40A, Section 3) works on a "prohibited unless enumerated" basis. That means if a use isn't specifically listed for a district, the town treats it as not allowed. There's no rural or agricultural district here aimed at raw land occupancy, so living in a vehicle, yurt, or temporary structure on vacant land isn't something the bylaw makes room for.
On dwellings, Belmont's bylaw defines "Dwelling" and "Dwelling, Single-Family" in pretty conventional terms, conventional residential buildings, and I found no provision for RVs or mobile units as permanent housing. Massachusetts has statewide Appendix Q standards that make small/tiny homes easier to permit in some towns, but whether Belmont has adopted that without added restrictions isn't confirmed in what I reviewed, so ask the Building Division directly.
Any construction beyond ordinary repair needs a permit and falls under the Massachusetts State Building Code, enforced locally by Belmont's Inspector of Buildings through the Building Division. That covers solar installs and other utility-related work too. I did not find a Belmont bylaw that specifically addresses disconnecting from the electric grid, but the permitting requirement for the physical work itself still applies.
On water and waste: Belmont is largely on municipal sewer, and the Board of Health has authority over any on-site septic or cesspool replacement, requiring its permission plus a sewer connection packet from the Health Department. I found no town-specific greywater ordinance, so it likely gets treated like other wastewater discharge under the statewide Title 5 framework, meaning it's restricted rather than freely permitted. Rainwater harvesting isn't addressed in anything I could find at the town level, so I'd assume the general state baseline applies (outdoor non-potable use is normally fine, indoor potable use is the sticking point) but confirm with the Board of Health.
Private wells in Massachusetts fall under local Board of Health jurisdiction, with MassDEP offering a model regulation towns can adopt or not. I could not confirm whether Belmont's Board of Health has adopted a private well regulation, and given how thoroughly sewered and water-served this town already is, I'd treat new private wells as a genuine question mark until you talk to them directly.
Bottom line: Belmont is not off-grid-friendly territory. If this is the town you're set on, your best move is a direct conversation with Planning & Building and the Board of Health before you buy or build anything.

FAQ
Common questions about off-grid living in Belmont
Can I legally live off-grid on vacant land in Belmont?
Realistically, no. Belmont's zoning bylaw only permits uses specifically listed for a district, and there's no district set up for raw off-grid occupancy like living in a vehicle or temporary structure on undeveloped land.
Are tiny homes allowed in Belmont?
Belmont's bylaw defines dwellings in conventional terms and I found no provision for RVs or mobile tiny homes as permanent residences. Confirm directly with the Building Division whether any tiny-home standards apply.
Can I install a composting toilet instead of connecting to sewer?
Not confirmed. Belmont's Board of Health oversees septic and sewer connections, but I found no specific composting-toilet policy, so you'd need to ask the Board of Health directly.
Can I drill a private well in Belmont?
Unclear. Private wells are regulated by local Boards of Health in Massachusetts, and whether Belmont has adopted the state's model well regulation isn't confirmed. Given the town is fully sewered and water-served, check with the Board of Health before assuming this is an option.
