Off-Grid Living in Canaan, Connecticut

I've been digging into what off-grid living actually looks like in Canaan (Falls Village), Connecticut, and the short answer is: this is a zoned town, so "off-grid" here means working within a real permitting structure, not disappearing onto raw land.

Zoning. The Town of Canaan's Planning & Zoning Commission adopted its Zoning Regulations under the state's enabling statute (Connecticut General Statutes Section 8-23), and those regulations apply to every parcel and structure in town. Land is split into districts, the Village Residential (VR) zone covers the historic village core, and the Residential/Agricultural (R/A) zone covers the more rural, farm-oriented land, with other districts (including a mountain residential zone) layered in. What you can build or do on raw land depends entirely on which district you're in, so I'd pull up the Commission's regulations and confirm your parcel's zone before assuming anything.

Dwellings, tiny homes, RVs. The regulations set dwelling standards by district, but I couldn't confirm specific rules on tiny homes or RV occupancy from what I reviewed, so treat that as an open question for the Building Inspector. What is confirmed: the town requires a building permit for any footprint expansion or accessory building over a certain size threshold, per the Building Inspector's office.

Building permits and codes. Canaan's Building Official enforces the state building code locally, coordinating with the Fire Marshal, the Inland Wetlands Commission, the Zoning Enforcement Officer, and the Torrington Area Health District (TAHD). That last connection matters a lot for off-grid setups, because your building permit process is tied to septic and well approval.

Septic, wells, and utilities. This is the crux of it. If you're building where there's no public sewer or water, which is most of Canaan, you need permits from TAHD to install a septic system and drill a well. TAHD is the state-delegated environmental health agency covering Canaan and several neighboring towns. And critically, the final Certificate of Occupancy from Canaan's Building Official won't be issued without that TAHD sign-off, meaning you genuinely can't live fully off-grid (no approved well, no approved septic) and still get a legal CO.

Greywater and rainwater. I found no Canaan-specific ordinance on household greywater reuse, so that one's genuinely unclear at the local level, worth a direct call to TAHD or the Building Inspector. Rainwater harvesting looks fine as a baseline matter (state building code has provisions addressing it), and I didn't find any town rule restricting it further.

Bottom line: Canaan isn't hostile to off-grid living, but it's not a free-for-all either. Every major system, dwelling, septic, well, occupancy, runs through a named local or district authority, and there's no shortcut around the CO requirement.
