Off-Grid Living in Sharon, Massachusetts

I'll say this up front: Sharon, Massachusetts is not a place to try to quietly disappear into the woods with a camper and a rain barrel. It's a fully zoned town, and off-grid living here means working within a fairly conventional New England regulatory structure rather than around it.

Zoning. Sharon's zoning bylaw (Chapter 275, adopted by Town Meeting under the state's MGL c. 40A) divides the town into districts, each with its own Table of Use Regulations and Table of Dimensional Regulations. That means what you can build, and where, depends entirely on which zoning district your parcel sits in. Using land or a structure for something not expressly allowed in that district is not permitted. If you're eyeing a specific lot, start by finding its zoning district and checking the tables in Chapter 275 on eCode360, or call the Building Division.

Dwellings, tiny homes, RVs. Any dwelling has to meet the Table of Dimensional Regulations (lot area, frontage, setbacks, coverage). I did not find a Sharon-specific minimum dwelling size exemption or an explicit rule on living in an RV full-time. That's a real gap in the public record, so I'd call the Building Division directly before assuming either is fine.

Building permits. Sharon's Building Division, under the Department of Public Works, issues permits and runs scheduled Building, Electrical, and Plumbing/Gas inspections. Anything needing a variance or special permit goes through the Zoning Board of Appeals.

Septic and composting toilets. This is state-driven with local backup: Massachusetts DEP's Title 5 (310 CMR 15.000) sets the baseline for all septic systems, and Sharon's Board of Health enforces its own Article 7 regulations on top of that, applying stricter local standards where they exist. No building permit gets issued until the Board of Health signs off on a lot for a septic system. The Board has also adopted its own chemical toilet regulations, so composting or chemical toilets are addressed locally, not left unregulated, and need Board of Health approval.

Greywater. Same Title 5 framework applies; greywater is treated as wastewater needing an approved disposal system. I found no separate Sharon greywater-reuse allowance.

Rainwater. No town-specific bylaw turned up in my research. Outdoor use is presumably fine as a state-baseline matter, but indoor/potable use runs into plumbing code and the Title 5 wastewater link. Not confirmed at the town level, worth asking the Building Division.

Wells. The Board of Health handles well and septic siting jointly, with the DPW Engineering Division acting as the Board's agent. Percolation and deep-hole tests need to be scheduled with real advance notice.

Off-grid utilities. Sharon's Building Division has a dedicated Electrical Inspector with set inspection days, and that applies to solar and other off-grid electrical work too, under the state's 780 CMR code, not a special exemption.

Bottom line: Sharon runs a normal, actively enforced permitting system. Nothing here says "no" to off-grid living outright, but almost everything runs through either the Building Division or Board of Health.
