Off-Grid Living in Cambridge, Maine

I'll be upfront: Cambridge, Maine is a tiny town (population 443 per the 2020 census) in Somerset County, and it's one of those places where the official paper trail online is thin. I dug through what's publicly available and I want to walk you through what I actually found versus what remains a question mark, because guessing wrong on this stuff can cost you.

Zoning. I could not find Cambridge's general zoning ordinance text posted anywhere online, on the town's own site or on a code host like Municode. That doesn't mean there's no zoning, it means I couldn't confirm it either way. What I can confirm is that Maine's Mandatory Shoreland Zoning Act, administered by the Maine DEP, requires every municipality (Cambridge included) to have a shoreland ordinance for land near water. If a town never adopted its own version, the state's model ordinance applies automatically. So if your land is anywhere near a lake, stream, or wetland, shoreland rules apply for certain, enforced locally by Cambridge's Code Enforcement Officer. For anything else, you'd need to call the town directly, since Cambridge does have a working Code Enforcement Officer, Planning Board, and Board of Appeals, which tells me some form of local ordinance structure exists even if I can't read the text myself.

Dwellings, tiny homes, RVs. No Cambridge-specific language on this turned up in my research. This would be governed by whatever local ordinance the Code Enforcement Officer applies, so this is a direct-call situation.

Building permits. Maine law (through the Office of State Fire Marshal) requires every municipality to have a Code Enforcement Officer who handles shoreland zoning, land use, plumbing, septic, and building standards. Cambridge's is Brian Turner, who also serves as Local Plumbing Inspector. Given the town's small size, it may fall under an optional path for statewide building code adoption, but I did not confirm that specifically for Cambridge, so ask Turner's office directly.

Septic and composting toilets. State rules permit composting and alternative toilet systems, and in Cambridge that permitting runs through the Local Plumbing Inspector, again Brian Turner.

Greywater. Handled the same way as septic, through state rules on subsurface wastewater disposal with local sign-off from the plumbing inspector. Expect to need a licensed site evaluator for any greywater disposal field.

Rainwater harvesting. I found no state or Cambridge rule addressing this either way. Nothing suggests it's restricted.

Wells. Private well drilling falls under Maine's statewide well construction framework; I found no Cambridge-specific well ordinance layered on top.

Off-grid utility disconnection. No explicit ordinance found. In practice, this outcome depends on how the septic, well, and building requirements get applied to your specific parcel by the town's Code Enforcement Officer.

Bottom line: Cambridge doesn't publish a lot of ordinance detail online, so a phone call to the town office is genuinely your best next step before you buy or build.
