Off-Grid Living in Trumbull, Connecticut

Trumbull, Connecticut is a fully zoned suburban town, and that fact alone should reset expectations for anyone dreaming of an off-grid homestead here. This is not a rural unzoned county in the West. The Trumbull Planning and Zoning Commission, acting under Connecticut General Statutes Section 8-2, has laid out a comprehensive plan with residential districts (Residence AAA, AA, and A) that carry minimum lot sizes of a half acre to a full acre. Nothing in those regulations that I could find treats raw-land camping or living in a structure without utilities as a permitted use.

On dwellings: I did not find anything in Trumbull's public materials that confirms tiny homes or RVs as legal full-time residences. The Planning and Zoning Department is the office that signs off on building permits and answers zoning questions, so if you're considering a small or alternative dwelling, that's who you call before you buy land or a trailer.

Building itself runs through the Trumbull Building Department, which reviews everything against the Connecticut State Building Code. A building permit here isn't a one-office errand, it requires sign-off from Planning & Zoning, Engineering, Inland Wetlands, the water pollution control authority, and the Health Department (which notes your well and septic status on the form). That layering is typical of Connecticut towns, but it does mean off-grid-style builds face more checkpoints than in looser jurisdictions.

Septic is squarely a Health Department matter. Trumbull's Health Department issues septic permits and inspects installations and repairs, and no changes to an approved system happen without the Director of Health's sign-off. I found no town-level guidance confirming composting toilets as an accepted alternative, so if that's your plan, ask the Health Department directly rather than assuming.

Greywater reuse: I could not confirm any Trumbull-specific policy either way. Rainwater harvesting has a permitted baseline under the Connecticut State Building Code, but I found no Trumbull ordinance layered on top of that, so treat the state rule as your floor and confirm nothing local changes it.

Private wells fall under Connecticut's Local Health Departments and Districts, which is Trumbull's Health Department in practice, with technical backup from the CT Department of Public Health's Private Well Program. Well status gets recorded right on the same building and septic paperwork.

Bottom line on utility disconnection: Trumbull's permitting web (Building, Health, Planning & Zoning) makes it hard to legally live fully off-grid on a residential lot here without some form of septic and well approval on record, and a Certificate of Occupancy needs those sign-offs. This is a town where you comply piece by piece rather than opt out entirely.
