Off-Grid Living in Westbrook, Connecticut

I've been digging into what off-grid living would actually look like in Westbrook, Connecticut, and the short answer is: this is a fully zoned coastal Connecticut town with layered rules, not a place where you can just quietly settle raw land.

Zoning. Westbrook is entirely zoned, with a Zoning Map and Regulations that spell out permitted uses district by district. The Zoning Commission (which updated the regulations as recently as June 2025) reviews site plans and special permits, and a chunk of the shoreline carries an added Coastal Area Management Overlay tied to the state's Coastal Management Act. Whatever you want to do with land here, you're checking the use table for that specific district first, and the overlay if you're near the coast.

Dwellings, tiny homes, RVs. I couldn't find a Westbrook-specific rule addressing tiny homes as permanent residences or RVs as dwellings. That doesn't mean it's allowed, it means it's not confirmed either way, so this is a direct question for the Land Use office before you buy or build anything unconventional.

Building permits. Westbrook has adopted the State of Connecticut Basic Building Code as its own, administered locally by the Building Department. Worth noting: under state law (CGS 7-148(c)(2)(B)), the town can't approve a building application if property taxes are delinquent.

Septic. This is where Westbrook gets notably strict. The town has no public sewer system, so it runs a "sewer avoidance" policy developed with the state DPH and DEEP, and every septic proposal, from new construction to additions to tear-down rebuilds, needs Health Department application and review. There's also a standing ordinance requiring septic systems be pumped and inspected on a five-year cycle. Composting toilets aren't addressed anywhere I found, so that's a call to the Health Department.

Greywater. No Westbrook ordinance on household greywater reuse turned up in my research. The town's sewage definition excludes roof, yard-drain, and floor-drain water, but sink and shower greywater isn't separately addressed. Treat this as unclear until the Health Department tells you otherwise.

Rainwater harvesting. I found no Westbrook rule restricting it, so the state Building Code provisions would govern by default. Worth double-checking locally since the absence of a rule isn't a guarantee.

Wells. Private well approvals run through the Public Health Department, which enforces the state Public Health Code for well siting and construction.

Full off-grid disconnection. Since every property here relies on an on-site septic system rather than sewer, and wells go through Health Department approval, a genuinely disconnected home still has to clear Health Department and Building Department sign-off. I didn't find explicit code language tying occupancy to utility hookups, so don't assume either way, ask directly.

Bottom line: Westbrook isn't hostile to self-sufficient living, but it's a town that wants paperwork on septic, wells, and construction, and several off-grid-relevant questions (tiny homes, greywater, RV living) simply aren't spelled out in what I could find. Call before you commit.
