Off-Grid Living in Plainville, Connecticut

Plainville, Connecticut is not the place for off-grid living in the "buy raw land and do whatever" sense. It's a zoned town, meaning the Planning and Zoning Commission controls where and how you can build, and the Building Department controls how you build it. If you're picturing a cabin with a composting toilet and a rain barrel tucked away in the woods here, you'll run into permit requirements at nearly every step.

Zoning. The Planning and Zoning Commission administers formal zoning districts with density minimums (single-family residential zoning in Plainville generally requires around 7,000 square feet of land per dwelling unit) plus setback and accessory-structure rules. This is a town-level framework, not a state mandate, and it applies to any new construction, addition, shed, or fence.

Dwellings, tiny homes, RVs. The Building Department requires zoning approval before any dwelling or accessory structure goes up. I did not find a specific town rule on living permanently in an RV or tiny home, so that's genuinely unconfirmed. I'd call the Building Department directly before assuming anything is allowed.

Building permits. The Building Department enforces both state and local codes, issues all permits, and now only accepts electronic permit applications through their online portal. No paper permits.

Septic and composting toilets. Septic work ties into both Building Department and health department approval. Public health oversight in Plainville runs through the South Central Health District (once known as Plainville-Southington Regional Health District). There's no separate town composting-toilet ordinance that I found, so it likely defaults to Connecticut's statewide Public Health Code standards, worth confirming with the health district.

Greywater. No Plainville-specific ordinance turned up in my research. This one is unclear at the town level, and I'd lean on state Department of Public Health guidance as the fallback, confirmed by asking the health district.

Rainwater harvesting. I didn't find a town restriction here. State building code provisions likely apply, administered through the Building Department when it comes to any physical plumbing or structure tied to a permit.

Wells. Well approvals appear to run jointly through the South Central Health District and Building Department as part of standard permit review, but I didn't find a standalone Plainville well ordinance beyond the state's Public Health Code baseline.

Utilities. Certificates of Occupancy are required for any living space, and the Building Department won't issue one without health and zoning sign-off, which in practice means code-compliant water and waste systems before you can legally live somewhere.

Bottom line: Plainville is a fully zoned, fully code-enforced town. Anything off-grid here needs to go through the Building Department and, for water/waste, the South Central Health District. Confirm specifics before you plan around gaps in what I found.
