Off-Grid Living in Old Saybrook, Connecticut

I'll be upfront: Old Saybrook, Connecticut is not the kind of place where you can buy a wooded lot and quietly go off-grid. It's a fully zoned town, with the Zoning Commission and Land Use Department administering a detailed code (Chapter 302/303 of the Town Code) that includes an Aquifer Protection Area, floodplain and coastal overlays, and inland wetlands review. Any land use, including "just living on" raw land, is going to run through that process.

Zoning and dwellings. The Town Code, per the Connecticut General Statutes' grant of authority to local zoning commissions, sets up district-by-district rules. RVs and "motorized campers" are explicitly defined in the zoning regulations as temporary or recreational uses, not year-round dwellings, so parking a camper on a lot and living in it full-time isn't something the code appears to allow outright. Manufactured homes are addressed separately with their own siting standards. If you're thinking tiny house or ADU, don't guess, call the Land Use Department and ask about foundation and occupancy requirements before you commit to anything.

Building permits. The Building Department follows Connecticut State Statutes for code enforcement, and a certificate of occupancy is required before a structure can be legally occupied. There are some permit exemptions I found worth knowing, small sheds under 120 square feet, driveways, and small tents don't need a building permit, but the town still wants the Land Use Department to sign off on placement.

Septic. Old Saybrook has its own sewage disposal ordinance (administered through the Water Pollution Control Authority) layered on top of state Department of Public Health rules. Notably, the town requires septic tanks to be pumped and inspected on a recurring schedule, with the Director of Health entitled to observe. Septic permitting itself is handled by the Connecticut River Area Health District (CRAHD), not an in-house town office, so that's who to call with system-specific questions. Composting toilets aren't addressed anywhere I could find, so I'd call CRAHD directly if that's your plan.

Wells. Because of the Aquifer Protection Area regulations the town maintains, well siting and land use over recharge zones face an extra layer of local review, on top of the state's standard well-construction rules.

Greywater and rainwater. I found no town-specific ordinance on residential greywater reuse, so I'm marking that unclear and leaning on whatever state baseline applies. Rainwater harvesting looks to be permitted, following the state building code baseline, with nothing at the town level that restricts it further.

Utilities. Between the certificate-of-occupancy requirement and the mandatory septic inspection ordinance, going fully off-grid on utilities for a permanent residence isn't a simple, low-friction path here.

Bottom line: Old Saybrook is livable off-grid in pieces (rainwater collection looks fine, for instance), but zoning, building, and septic oversight are all real and locally enforced. Call before you build.
