Off-Grid Living in Rocky Hill, Connecticut

I've spent some time digging through Rocky Hill's town code and official pages to see what off-grid living actually looks like here, and the short version is: this is a fully zoned, fully regulated New England town. That's not a knock on it, it just means anyone dreaming of a quiet off-grid parcel needs to plan around a real regulatory framework rather than open land.

Zoning. Rocky Hill is not unzoned. The Planning and Zoning Division administers the Rocky Hill Zoning Regulations (codified in Chapter 245 of the Town Code), and the Zoning Enforcement Officer handles day-to-day enforcement along with support to the Zoning Board of Appeals. There's also a specific local rule I noticed: the town generally won't issue a building permit for a lot that lacks frontage on an accepted, improved street unless the Planning and Zoning Commission approves it through a subdivision plan. If you're eyeing a landlocked or unimproved-road parcel, that's worth asking about early.

Dwellings, tiny homes, RVs. I couldn't find Rocky Hill zoning text that specifically addresses tiny homes or RVs as permanent dwellings, so treat this as a case-by-case call by the Zoning Enforcement Officer, not a settled yes or no. One concrete detail I did find: small accessory structures under 200 square feet, if detached from the main house, need only a Zoning Permit and are exempt from a full Building Permit.

Building permits. Connecticut's State Building Code (the International Building Codes with state amendments) governs construction here, and Rocky Hill's Building Department issues and enforces the permits locally, for new construction, additions, and any alterations or occupancy changes.

Septic, wells, and utilities. Rocky Hill contracts its public health functions to the Central Connecticut Health District (CCHD), which enforces the state Public Health Code on private wells and septic systems. Both require CCHD review. I didn't find anything addressing composting toilets specifically, so ask CCHD directly if that's your plan. Because occupancy approval ties back to Building Code and Health District sign-off on water and sewage, going fully disconnected from utilities isn't something the town spells out as banned, but in practice it's hard to get a certificate of occupancy without an approved well and septic system.

Greywater. I found nothing town-specific on greywater reuse. It likely falls under CCHD's general sanitary review, but there's no dedicated ordinance I could confirm, so ask CCHD before setting up any greywater system.

Rainwater harvesting. No local restriction turned up in my research. The state Building Code's rainwater provisions apply as the baseline, and the Building Department would field any permit questions if you're integrating catchment into a structure.

Bottom line: Rocky Hill isn't a place to try to fly under the radar. Talk to Planning & Zoning first about the land itself, then Building and CCHD about the systems.
