Off-Grid Living in Lisbon, Connecticut

I've been digging into what off-grid living actually looks like in Lisbon, Connecticut, and the short version is: this is a zoned town, so you're working within real local rules, not a blank slate.

Zoning. Lisbon is not unzoned. The town's Planning & Zoning Commission administers its own Zoning & Subdivision Regulations, adopted under Connecticut's Zoning Enabling Act, and there's a Zoning Enforcement Officer on staff. There's a Residential Zoning Permit Application, which tells me raw-land building or occupancy is actively regulated here, not just theoretically covered. If you're eyeing a parcel, start with the Planning & Zoning Commission page before you assume anything.

Dwellings, tiny homes, RVs. I could not confirm specific rules on tiny homes, minimum dwelling size, or full-time RV living from Lisbon's official pages. The town's 2025 Zoning Regulations PDF probably has dimensional standards, but I haven't verified tiny-home or RV-specific language, so treat this as unclear until you ask the Zoning Enforcement Officer directly.

Building permits. Lisbon has its own Building Department issuing permits under the state building code. Any new dwelling needs a Zoning Permit and Building Permit, and notably, a Uncas Health District application has to be approved first, before the town will process your building or zoning permit. That's a real gate to plan around.

Septic. Septic permitting isn't done by the town at all, it's delegated to the Uncas Health District, a regional local health department covering Lisbon and ten other towns. Their process (per Connecticut Public Health Code) involves plan review, soil and percolation testing, and permitted, inspected installation. I found no Lisbon or Uncas page specifically addressing composting toilets, so that piece is unconfirmed, ask Uncas directly.

Greywater. No Lisbon or Uncas ordinance on residential greywater reuse turned up in my research. This looks like an area where the town simply hasn't addressed it, which is common in Connecticut generally.

Rainwater harvesting. I didn't find anything in Lisbon restricting rainwater collection beyond the standard state building code requirements for any structural components. This looks permitted by default.

Wells. Wells go through the Uncas Health District, not the town. Based on how comparable districts in the same regional network operate under the same state Public Health Code sections, expect a licensed well driller, District approval before drilling, a completion report, and a water quality test after installation. Confirm Lisbon-specific procedure with Uncas.

Utilities. There's no explicit ban on disconnecting from the grid that I found, but since the Uncas Health District has to sign off on water/septic before you get a building or zoning permit, full off-grid utility independence is functionally tied to satisfying that health district review.

Bottom line: Lisbon is zoned and permit-heavy compared to unzoned Connecticut towns, and the Uncas Health District is a gatekeeper you can't skip for septic or wells.
