Read this before you act on anything below. This is my researched starting point for Northwest Hills Planning Region, CT, 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.

The local rulesNorthwest Hills Planning Region, CT (state framework; no county page yet)

Zoning & raw-land occupancy

Varies locallyConnecticut has no statewide zoning code; each town adopts its own regulations under the state's Zoning Enabling Act, so raw-land occupancy rules vary by municipality. source

Dwellings, tiny homes & RVs

Varies locallyThe State Building Code allows tiny homes up to 400 square feet, but whether one can be a full-time residence, ADU, or requires a foundation is decided by local zoning, which differs town to town.

Building permits & codes

RestrictedConnecticut has adopted an ICC-based State Building Code statewide, but permits and inspections are issued by local building departments. source

Septic & composting toilets

RestrictedSeptic systems are regulated under DPH's Public Health Code (Section 19-13-B103 and related sections) and permitted locally by the town Director of Health; composting toilets require case-by-case local health director approval. source

Greywater reuse

Unclear - verifyNo dedicated Connecticut statute or code section for household greywater reuse was found; DEEP has a broader water-reuse policy document but not confirmed as a specific permitting framework. Ask your local health director if greywater ties into a septic system. source

Rainwater harvesting

Generally allowedRainwater collection is legal in Connecticut and addressed directly in Section 1303 of the State Building Code, though a permit is required to install or repair a collection system.

Private wells & water rights

RestrictedWell construction is governed by DPH Public Health Code Sections 19-13-B51(a)-(m), with local health directors reviewing water quality tests before a new well goes into service; there's no state post-drilling inspection or mandated ongoing maintenance testing. source

Living disconnected from utilities

RestrictedNo state law bans disconnecting from utilities, but most towns won't issue a certificate of occupancy without approved well water tests and code-compliant sewage disposal, per state health department authority. source
