Off-Grid Living in Stonington, Connecticut

I've been digging into what off-grid living actually looks like in Stonington, Connecticut, and the honest answer is: this is a zoned town with active local oversight, not a place where you can just quietly set up on raw land and disappear from the system.

Zoning. Stonington is fully zoned, administered by the Planning Department and Planning & Zoning Commission. The town has been in the middle of a comprehensive rewrite of its regulations (the old base dated to 1961, last comprehensively updated in 1979), with new regulations adopted more recently. I did not find specifics on minimum lot sizes or raw-land camping in what I could pull up, so if you're eyeing a specific parcel, call Planning directly before assuming anything is allowed.

Dwellings, tiny homes, RVs. I could not confirm town-specific rules on tiny homes or living in an RV long-term. Connecticut's state building code sets a general floor here, but Stonington's own zoning text on this wasn't something I could verify directly, so treat this as unclear until you ask Planning or the Building Department.

Building permits. The Town of Stonington's Building Official's office requires all permits to go through the town's online portal (they moved away from paper submissions a while back). Work can't legally start until both zoning and building permits are issued, and the town does have a penalty structure for non-compliance. Call the Building Department before you break ground on anything.

Septic and wells. This is handled not by the town directly but by Ledge Light Health District, the local health authority covering Stonington. They review soils, approve septic system plans and repairs, and also approve well locations, construction, and testing. Septic systems need an inspection before they're covered over. I did not find anything specific on composting toilets, so ask Ledge Light directly if that's your plan.

Greywater. I found no Stonington or Ledge Light Health District ordinance addressing greywater reuse specifically. This is a genuine gap in what's publicly documented, not a confirmed "yes" or "no."

Rainwater harvesting. I didn't find any town-specific restriction, and Connecticut's state building code has general provisions that would apply as a baseline. I can't confirm the town adds anything on top of that.

Utilities. There's no explicit off-grid utility ban that I could confirm, but in practice, occupancy sign-off runs through the Building Department and Ledge Light Health District, both of which expect a code-compliant water and wastewater setup. That functionally makes full off-grid utility independence harder to pull off without at least a compliant well and septic system in place.

Bottom line: Stonington isn't hostile to homesteading-style living, but it's not a legal gray zone either. Every major system, water, waste, structure, needs sign-off from either the town or Ledge Light Health District.
