Off-Grid Living in Westport, Connecticut

Westport, Connecticut is not a place to try to slip below the radar of local government, and I want to be upfront about that before we get into specifics. This is a fully zoned, affluent Fairfield County town with an active Planning & Zoning Commission, a Building Department that enforces the Connecticut State Building Code, and septic/well oversight handled by a regional health district. Off-grid living here is possible in pieces (rainwater harvesting looks fine, for instance) but you're working within a dense permitting structure at every level, not around it.

Zoning. The Town of Westport's Planning and Zoning Commission maintains comprehensive zoning regulations, with multiple residence districts (AAA, AA, A, B, C), a mobile home park district, and an open space residential district. You can't just occupy raw land; whatever you build or park has to conform to the district it sits in. This is set at the town level, administered under Connecticut's Zoning Enabling Act.

Dwellings, tiny homes, RVs. I did not find a Westport-specific carve-out for tiny homes or RVs as permanent residences. Connecticut runs one State Building Code statewide, with only minor local climatic/geographic tweaks for Westport, so any residential structure gets reviewed the same way. Whether an RV can be a permanent dwelling here isn't confirmed in what I found, call Planning & Zoning before you assume anything.

Building permits. The Westport Building Department reviews all residential, commercial, and municipal construction against the state code and issues the permits. This is the town-level gatekeeper for anything you build.

Septic. Septic permitting isn't handled by the town directly, it's delegated to the Aspetuck Health District (serving Westport, Weston, and Easton), which enforces the state Public Health Code plus its own local sanitary code, including plan review and inspections. Composting toilets aren't separately addressed in what I found, so ask the health district directly.

Greywater. No Westport or Aspetuck-specific greywater rule turned up in official sources. This is genuinely unclear, and it inherits the same ambiguity Connecticut has at the state level. Don't guess, ask the health district before installing a greywater system.

Rainwater harvesting. Nothing suggests Westport restricts this beyond the general state building code framework, and it seems to be treated as a normal permitted feature through the Building Department's process.

Wells. Also handled by the Aspetuck Health District, not the town. State health code requires testing of newly constructed wells, and the health district actively tracks well conditions, reporting damaged wells annually to the state. This is real, ongoing oversight, not a rubber stamp.

Living off-utilities generally. There's no outright ban I found on disconnecting from municipal utilities, but in practice your septic and well work run through the Aspetuck Health District as part of any building or zoning approval, so full self-sufficiency still has to clear that review chain.

Bottom line: Westport allows off-grid-style systems (well, septic, rainwater) but nothing here is a workaround for permits. Confirm every specific with Planning & Zoning, the Building Department, or Aspetuck Health District before you buy land or break ground.
