I've spent time digging through Preston, Connecticut's town documents and Connecticut state code to figure out what off-grid living actually looks like here, and the short version is: Preston is a fully zoned town, and that shapes just about everything below.
Zoning. Preston has an adopted Zoning Regulations document, a Planning & Zoning Commission, and a Zoning Enforcement Officer (ZEO) who administers it. No use of land, and no change of use, happens without a zoning permit from that office. So if you're picturing quietly parking a camper on raw land and living there, that's not how it works here, the ZEO's office needs to sign off first.
Dwellings, tiny homes, RVs. New dwellings go through zoning permit review by the ZEO. RVs in RV parks specifically need authorization from the park owner/association before the town will even accept a permit application. I didn't find any special tiny-home exemption in Preston's regs, so assume the standard dwelling and building rules apply unless the ZEO tells you otherwise.
Building permits. This is a multi-department process in Preston: Planning & Zoning, the Health Department, the Sanitarian, and Inland Wetlands may all need to weigh in depending on the project, and a permit is required for basically any construction, alteration, or system change (electrical, gas, mechanical, plumbing).
Septic and composting toilets. Septic is regulated at the state level by the Connecticut Department of Public Health (Public Health Code, Environmental Engineering program) for systems handling 7,500 gallons/day or less, but locally the Preston Health Department/Town Sanitarian handles permitting and complaints, and any building work on a septic-served property needs their sign-off too.
Greywater. I couldn't find a Preston-specific greywater ordinance. This one is genuinely unclear at the local level, treat it as governed by whatever general state guidance applies until you've confirmed with the Health Department.
Rainwater harvesting. No Preston-specific restriction turned up. The statewide building code sets permit requirements for installing or repairing rainwater collection systems, and Preston's Building Department handles that as part of its normal permitting.
Wells. Well matters run through the same Local Health Department channel as septic. I didn't find a standalone Preston well ordinance, so contact the Health Department directly.
Off-grid utilities generally. Preston ties Certificate of Occupancy sign-off to Zoning, Building, and Health Department approval together, so any off-grid water or waste setup has to satisfy all three before the town will certify the home as occupiable.
Bottom line: Preston isn't hostile to off-grid systems, but it is a well-organized, multi-department town where nothing gets rubber-stamped without paperwork. Call before you build.
