Off-Grid Living in Madison, Connecticut

I've been digging into what off-grid living actually looks like in Madison, Connecticut, and the short version is: this is a fully zoned shoreline town with an active Health Department and Planning & Zoning Commission, and that combination makes a true "disconnect from everything" off-grid setup very hard to pull off legally.

Zoning. Madison has its own zoning and subdivision regulations, administered by the Planning & Zoning Department, and enforced through the Planning & Zoning Commission and Zoning Board of Appeals. There's also a town-specific Aquifer Protection Area overlay that restricts certain land uses near water supplies. Zoning review is now folded into the standard building permit process rather than being a separate track, so raw land isn't a free-for-all here, whatever you build has to clear both zoning and building review.

Dwellings, tiny homes, RVs. I couldn't find a Madison-specific rule addressing tiny homes or RVs as full-time residences. What I can confirm is that the town's Building Department requires permits for essentially all construction (with a narrow exception for minor repairs to existing structures), and ADUs are handled through Planning & Zoning. If you're thinking about a tiny house or RV as a permanent home, call the Planning & Zoning Department directly before you buy land or a trailer.

Building and septic. The Building Department issues permits and does inspections per the state Building Code, and any new house application goes through the Wetlands Official, the Health Department, and Engineering (if in a flood zone) before the Building Department signs off. The Health Department's septic review is a real gatekeeper: septic design and installation follows the Connecticut Public Health Code, and the town requires Health Department approval before a building permit for a new home is even issued.

Greywater. I found nothing on Madison's own site addressing residential greywater reuse specifically, so this one falls back to Connecticut's state-level guidance. Treat it as unclear locally and ask the Health Department directly.

Rainwater. No Madison-specific restriction turned up in my research; state building code applies to any collection structure, and Madison's general permitting rules would apply if you're building something to hold it.

Wells. Any construction near a well, like a deck or addition, requires a site plan showing distances to both septic and well. The Health Department weighs increased water use and lot coverage against whether there's still room for a compliant septic system.

Bottom line on utilities. Because Health Department sign-off is required before most residential permits, and occupancy requires a final inspection and Certificate of Occupancy, going fully off-grid (skipping septic or well compliance) isn't really something Madison's permitting system has a lane for. That doesn't mean solar power or a well instead of town water is off the table, it means the sewage and water pieces still have to pass muster.

As always, town rules can and do get more specific than what's posted online, so a call to Planning & Zoning or the Health Department before you commit to a property is worth the time.
