Off-Grid Living in Ridgefield, Connecticut

I'll say this up front: Ridgefield, Connecticut is not a place where you can just buy a wooded lot and quietly go off-grid. It's a fully zoned town, and multiple town and state offices have to sign off before you can legally live on a property, whether you want to or not.

Zoning. The Ridgefield Planning and Zoning Commission divides the whole town into residential and special districts, with lot-coverage, setback, and density rules spelled out in the Zoning Regulations. I didn't find anything in the town's regulations that treats raw-land camping or living outside an approved dwelling as a permitted use, so I'd call that restricted rather than open.

Dwellings, tiny homes, RVs. The regulations govern dwelling types, floor area, and accessory dwelling units, and cap the number of dwelling units per lot based on the zoning district. I found no specific carve-out for tiny homes or RVs as permanent residences. That likely means it gets decided case by case by Planning & Zoning and the Building Department, so don't assume either is automatically allowed.

Building permits. Ridgefield enforces the Connecticut State Building Code through its own Building Department, which reviews plans, issues permits, inspects, and signs off on Certificates of Occupancy. Notably, the town's code says no building permit gets issued until zoning, septic, and (where applicable) sewer approvals are already in hand, along with Fire Marshal review.

Septic and composting toilets. Septic systems fall under the state Public Health Code, administered locally by Ridgefield's Health Department. You'd need a licensed engineer or septic installer to do soil testing and design work, which then goes to the Health Department's Sanitarian for approval before a licensed installer can build it and get it inspected. I found no town ordinance addressing composting toilets one way or the other, so treat that as unconfirmed and worth a direct call to the Health Department.

Greywater and rainwater. I couldn't find any Ridgefield-specific rule on household greywater reuse, and Connecticut doesn't appear to have a dedicated state statute either, so this is genuinely unclear at the town level. Rainwater harvesting looks more straightforward: I found no town restriction beyond whatever the state building code's general permitting provisions require.

Wells. Private well permits go through the Health Department, working alongside Building and Zoning, per the town's own land-use application listings.

Full utility disconnection. This is the big one: Ridgefield's code is explicit that no certificate of occupancy can be issued without the Health Department confirming your septic or sewer hookup complies with its rules. In practice, that means you can't get a legal occupancy sign-off while living fully off-grid on wastewater, even if your power and water setups are otherwise fine.

Bottom line: Ridgefield layers state building and health code on top of its own zoning and building rules, and the town's Health Department is a gatekeeper for septic, wells, and occupancy alike. Anyone serious about this should call the Health Department and Planning & Zoning before buying land here.
