Off-Grid Living in Killingworth, Connecticut

Killingworth, Connecticut is a fully zoned, rural-residential town, and that surprises some people who assume off-grid living means "no rules." It doesn't work that way here. The Planning and Zoning Commission adopted comprehensive Zoning Regulations (Chapter 500) back in 1957 and has amended them since, and a Zoning Enforcement Officer enforces them. If a use isn't specifically permitted, it's treated as prohibited, and much of the town carries large-lot requirements. So before you buy raw land here thinking you'll just live on it quietly, understand you're working within an actual regulatory framework, not a blank slate.

On dwellings: I found no path in the zoning code for full-time RV or tiny-home living as a primary residence. In fact, the town's mobile-home and trailer provisions go out of their way to say that camping/recreational/utility trailers can be parked or stored on private residential property, but cannot be occupied for living, sleeping, or housekeeping, and cannot be hooked up to any utility service (electric, heat, water, sewage). Mobile and manufactured homes are restricted to specific districts and situations. Larger trailers need a zoning permit. That combination effectively closes off the "park a camper and live in it" option as a legal long-term strategy.

Building falls under Connecticut's statewide Building Code, enforced locally by Killingworth's Building Department, which reviews plans for new buildings, additions, and accessory structures. Separately, the town's own zoning permit is required any time you place or change an improvement on land, so you're often dealing with two departments, not one.

Septic is a big deal here because Killingworth is, in the town's own words, "all septic and all wells." The Health Department (Director of Health or an agent) oversees on-site sewage disposal system approvals, following state Public Health Code standards, and the town requires septic tanks be pumped on a set schedule, more often for undersized or poorly functioning systems. I did not find a specific composting-toilet ordinance, so treat that as unconfirmed and check with the Health Department directly before relying on one.

Greywater reuse and rainwater harvesting: I found no Killingworth-specific ordinances addressing either. That means you're likely operating under the state baseline only, but I can't confirm there isn't a local wrinkle, so ask the Land Use or Health Department.

Wells are locally overseen by the Health Department, coordinating with the state DEEP on water quality and contamination concerns.

Bottom line on "disconnecting from utilities": there's no blanket town ban on off-grid systems for a proper dwelling, but the trailer rules explicitly forbid unconnected occupancy for trailers, and any permanent home still needs approved septic and well systems through local Health and Land Use channels. Off-grid here means "self-sufficient but still permitted," not "unregulated."
