Off-Grid Living in East Haven, Connecticut

East Haven is a fully zoned Connecticut town, so if you're picturing raw off-grid land here, set your expectations accordingly. This isn't unzoned rural county land out west, it's an incorporated town with an active Planning and Zoning Commission whose regulations date back to 1936 and were most recently amended in 2025.

Zoning: The town's zoning code divides East Haven into a long list of districts (R-1 through R-5, RA-1, RA-2, several commercial and industrial categories). What you can build or do on a given parcel depends on which district it sits in, and that's administered by the Planning and Zoning Department. There's no "off-grid exemption" in the code, and raw land use is governed district by district. If you're eyeing a specific lot, call Planning and Zoning before you buy.

Dwellings, tiny homes, RVs: I didn't find any tiny-home or RV-as-permanent-residence provisions specific to East Haven. What is clear: Connecticut state statute (and the town, echoing it) requires a Certificate of Occupancy before you legally occupy any newly built structure, and that C.O. only comes after Zoning and the Health Department sign off. So parking an RV as a full-time residence, or dropping a tiny house without going through the permit process, is not confirmed to be legal and I'd assume it's restricted until Planning and Zoning tells you otherwise.

Building permits: The Building Department enforces the State of Connecticut Building Code, as required under state law (CGS Sec. 29-253). Owner-occupants can do their own work on a one-family home, but you still need to pull permits and schedule inspections. No shortcuts here.

Septic and wells: East Haven doesn't run its own health department. Instead, the East Shore District Health Department (ESDHD), which also covers Branford and North Branford, handles septic system permits and well/water approvals under the state Public Health Code. Composting toilets aren't addressed in any town-specific document I found, so that question goes to ESDHD directly.

Greywater: I found nothing in East Haven's ordinances or ESDHD's materials that specifically addresses household greywater reuse. Treat this as unresolved and ask ESDHD how they'd handle a proposed greywater system.

Rainwater harvesting: No town restriction turned up. The state Building Code has provisions covering rainwater systems, and the Building Department administers that locally, so this looks permitted as a baseline, but confirm any specifics with them.

Utility disconnection: Because occupancy is legally tied to a Certificate of Occupancy, and that requires Zoning and Health Department sign-off, going off-grid on water and wastewater doesn't get you around the permitting process, it just means your septic/well and other systems need to be code-compliant before you can legally live there.

Bottom line: East Haven's rules are set at multiple levels, state statute for building codes, a regional health district for septic and wells, and the town for zoning and occupancy. Nothing here suggests East Haven is a permissive place for informal off-grid living, so budget time for real conversations with Planning and Zoning, the Building Department, and ESDHD.
