Off-Grid Living in Prospect, Connecticut

I'll say upfront: Prospect, Connecticut is a zoned town, not the kind of unzoned rural spot where off-grid living tends to be easiest. That doesn't mean it's impossible, but it does mean you're working within a formal framework run by the Planning & Zoning Commission and enforced by the Land Use Inspector, on top of Connecticut's statewide building and health codes. Here's what I found digging through official sources.

Zoning. Prospect adopted its Zoning Regulations back in 2008 and maintains residential districts (RA-1 at one acre, RA-2 at two acres) plus business zones and an aquifer protection overlay. Raw land isn't a free-for-all here: accessory structures and most site uses need a Zone Permit from the Land Use Office before you build or occupy anything.

Dwellings, tiny homes, RVs. This is genuinely murky. I could confirm that the Land Use Inspector can kick a project up to the full Commission for a public hearing, but I could not pin down Prospect's specific stance on tiny homes as permanent residences or RVs as full-time dwellings. If that's your plan, call the Land Use Office directly and ask them to walk you through the dwelling-unit definition in the current regulations.

Building permits. The Prospect Building Department enforces the state's ICC-based building code locally. Minor cosmetic repairs are exempt from permitting, but anything touching water supply, sewer, drainage, gas, or structural elements is not exempt, so plan on a permit for most off-grid infrastructure work.

Septic and composting toilets. Septic systems fall under the Connecticut Public Health Code, with the Local Director of Health approving systems under a set flow threshold. In Prospect, that local health authority role is handled by the Chesprocott Health District rather than a town health department. I did not find anything confirming composting toilets as a standalone sanitation solution in local rules, so this needs a direct conversation with Chesprocott.

Greywater. No Prospect-specific or state DPH rule on household greywater reuse turned up in my research. That leaves it genuinely unclear, treat it as unaddressed rather than clearly legal.

Rainwater harvesting. I found no Prospect ordinance restricting this. The state building code has a relevant provision, and any installation tied to plumbing would run through the local Building Department for a permit, but collecting rainwater itself doesn't appear prohibited.

Wells. New private wells fall under the state Public Health Code, which requires bacteria, metals, and non-metals testing on newly constructed wells. Locally, that testing and review runs through Chesprocott Health District.

Off-grid utilities. I found no Prospect ordinance specifically banning full utility disconnection, but a certificate of occupancy from the Building Department generally assumes code-compliant water and sewage systems, so going fully off-grid on utilities while still seeking an occupancy certificate could get complicated. Ask the Building Department directly about this before committing.

Bottom line: Prospect isn't hostile to off-grid elements like rainwater collection or wells, but it is a fully zoned town with active enforcement, and several of the specifics that matter most for off-grid living (tiny homes, RVs, composting toilets, greywater) aren't spelled out clearly in what I found. This is a "call before you build" town.
