Off-Grid Living in Southington, Connecticut

I've been digging into what off-grid living actually looks like in Southington, Connecticut, and the short version is: this is a zoned, code-enforced town, and going fully "off-grid" here means working with the Planning & Zoning Department, the Building Department, and the local health authority, not around them.

Zoning. Southington has its own Zoning Regulations, adopted by the Planning and Zoning Commission under Connecticut's state Zoning Enabling Act, with a map full of conventional residential, business, and industrial districts (R-80, R-40, R-20/25, etc.). The regulations are written so that anything not clearly listed as permitted is presumed prohibited. That's important for off-gridders: there's no "just go build a cabin in the woods" option without a zoning determination first. Call the Zoning Enforcement Officer before you buy land or start planning.

Dwellings, tiny homes, RVs. I didn't find Southington-specific text addressing tiny houses, ADUs, or living in an RV full-time. What I did confirm is that every building application, per the Building Department, requires a zoning determination before a permit is issued. So the honest answer is: not confirmed for specifics, but expect it to be restricted in practice until you've cleared it with zoning and building staff.

Building permits. The Building Department enforces the State of Connecticut Building Code plus state statutes and local ordinances, reviews plans, inspects, and issues Certificates of Occupancy. Applications go through the town's online system. Nothing here is optional if you're constructing a permanent structure.

Septic. The Director of Health (administered locally through Southington's health authority) won't approve a new septic system if public sewer is available, and where it isn't, you need a licensed installer and a written health permit, meeting state Department of Public Health design standards. Composting toilets aren't addressed separately in what I found, so confirm that directly with the health office.

Greywater. No Southington-specific greywater ordinance turned up in my research. This is genuinely unclear at the local level, so ask the health department directly before setting up any reuse system.

Rainwater harvesting. I found no local restriction beyond the general state building code permitting that would apply to any installed catchment system, so this looks permitted, but check with Building if your system involves plumbing or structures.

Wells. Wells require a licensed well driller and a written health department permit before drilling, following Connecticut's statewide well drilling regulations and Public Health Code sections. This is a firm state-level requirement administered locally.

Full utility disconnection. There's no outright ban I found on going off the electric or water grid, but Certificate of Occupancy requirements and mandatory septic/well permitting make a fully "invisible" off-grid setup impractical without going through these approvals first.

Bottom line: Southington isn't hostile to off-grid ideas, but it is a fully zoned, code-heavy town, and the burden is on you to get determinations before you build, dig, or drill.
