Off-Grid Living in Union, Connecticut

Union, Connecticut is a zoned town with an active Planning and Zoning Commission, Zoning Enforcement Officer, and Board of Appeals, so off-grid plans here go through local review, not a legal gray zone. Septic and well matters run through the regional Northeast District Department of Health rather than a town health office, and several specifics (tiny homes/RVs, greywater rules) simply weren't confirmed in available sources.</summary> <parameter name="framework">{"zoning":{"status":"restricted","note":"Union has its own Planning and Zoning Commission and zoning regulations (effective 6-5-24), plus a Zoning Enforcement Officer and Zoning Board of Appeals.

Is it legal to live off-grid in Union, Connecticut?

There is no outright ban on living off-grid in Union, Connecticut - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is not clearly documented online, so confirm it locally, and building permits are restricted. Plan around septic/wastewater (restricted) and disconnecting from utilities (restricted). Because these rules are set locally, confirm the specifics with Union before you buy land or build.

Read this before you act on anything below. This is my researched starting point for Union, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

Union at a glance

Zoning & raw-land occupancy
RestrictedUnion is a zoned town with its own Planning and Zoning Commission, Zoning Enforcement Officer, and Inland Wetland Commission overseeing land use. Specific standards on lot size, setbacks, and raw-land occupancy are set in the town's own zoning regulations, so check with the Zoning Enforcement Officer before settling on raw land. source
Dwellings, tiny homes & RVs
Unclear - verifyI couldn't confirm any specific Union rule on tiny homes, RV living, or ADUs. This would fall under the town's zoning regulations (effective June 2024), so ask the Zoning Enforcement Officer or Planning & Zoning Commission directly before you buy a tiny home or plan to live in an RV.
Building permits & codes
RestrictedConnecticut has a statewide building code administered locally, and Union has a Building Inspector function whose decisions can be appealed to the Zoning Board of Appeals. Any new construction, addition, or change of use needs to go through that process, so confirm requirements with the town's Zoning Enforcement Officer or the state Office of the State Building Inspector. source
Septic & composting toilets
RestrictedUnion doesn't have its own health department, it's covered by the Northeast District Department of Health, which reviews and approves septic system installs, repairs, and expansions under the state's Public Health Code. Composting toilets aren't separately addressed, so I'd confirm with NDDH before going that route. source
Greywater reuse
Unclear - verifyI found no Union-specific rule or clear state statute permitting standalone greywater reuse systems; the state Public Health Code touches on graywater in the context of septic regulation but a distinct reuse allowance isn't confirmed. Ask the Northeast District Department of Health before setting one up.
Rainwater harvesting
Generally allowedNo Union-specific ordinance restricts rainwater collection, so the state building code baseline appears to apply. Still worth a quick check with the Zoning Enforcement Officer if you're building a dedicated catchment structure.
Private wells & water rights
RestrictedThere's no separate Union well ordinance found, but private wells fall under the Northeast District Department of Health's oversight, the same office that handles septic and drinking water testing. Get your well reviewed there before drilling.
Living disconnected from utilities
RestrictedI found no explicit Union ordinance banning off-grid utility disconnection, but as in most Connecticut towns, a certificate of occupancy likely depends on sign-off from the Zoning Enforcement Officer and Northeast District Department of Health on septic and well systems. This link isn't directly confirmed in Union's own documents, so ask the Zoning Enforcement Officer directly.

I'll level with you up front: Union, Connecticut is a small, rural town, but it is NOT unzoned. It has an active Planning and Zoning Commission with its own zoning regulations (effective 6-5-24), a Zoning Enforcement Officer, a Zoning Board of Appeals, and an Inland Wetland Commission. If you're picturing Union as some loophole town where you can just plunk a camper on raw land and live quietly forever, I haven't found evidence to support that.

Zoning and raw land. The Planning and Zoning Commission administers local zoning rules, and the Zoning Enforcement Officer (currently Andrew Marchese, per the town site) handles compliance questions. I did not find the actual setback, minimum lot size, or camping/dwelling standards in the portions of the regulations I could access, so anyone serious about buying land here should get the full zoning regs document from the town and talk to the Zoning Enforcement Officer before assuming anything is allowed.

Tiny homes, RVs, alternative dwellings. Not confirmed. I found no specific Union provision addressing RV occupancy, tiny homes, or ADUs. This would fall under the town's zoning regs, which I could not review in full text, so ask the Zoning Enforcement Officer directly.

Building permits. Connecticut has a statewide building code administered by the Office of the State Building Inspector, and locally, Union's Building Inspector's decisions can be appealed to the town's Zoning Board of Appeals, which confirms a local building permitting function exists here even though I couldn't find a dedicated town building department page.

Septic and wells. Union doesn't run its own health department. Health and environmental functions, including septic system review and approval and drinking water testing, are handled by the Northeast District Department of Health (NDDH), a regional authority. Connecticut's Public Health Code sets the statewide framework for septic systems up to a certain daily flow, administered by local health directors, which in Union's case means NDDH.

Greywater. Not confirmed. I didn't find a standalone Connecticut or Union rule permitting or restricting household greywater reuse outside the general subsurface sewage code.

Rainwater harvesting. As far as I found, rainwater collection is fine under the state building code baseline, with no extra restriction specific to Union.

Utility disconnection. Not explicitly banned in anything I found, but the practical reality in most Connecticut towns is that certificate of occupancy depends on the local zoning officer and health authority signing off on septic and well systems, so full off-grid disconnection likely runs into that process even if no ordinance says "you must connect to utilities."

Bottom line: Union has real zoning and health oversight through NDDH, it's just spread across town and regional offices rather than one big building department. Call before you buy or build.
