Read this before you act on anything below. This is my researched starting point for Kent County, RI, 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 rulesKent County, RI (state framework; no county page yet)

Zoning & raw-land occupancy

Varies locallyThe state Zoning Enabling Act (RIGL Chapter 45-24) lets each city/town set its own districts and permitted uses; there's no statewide right to occupy raw land, so check your specific town. source

Dwellings, tiny homes & RVs

Varies locallyNo dedicated state tiny-home law; foundation dwellings fall under the State Building Code and RVs/tiny homes on wheels are governed by local zoning and building rules. source

Building permits & codes

Generally allowedA mandatory statewide code exists under RIGL Chapter 23-27.3, but local building officials issue the actual permits and certificates of occupancy; no off-grid exemption exists. source

Septic & composting toilets

RestrictedDEM requires OWTS to be designed and installed by DEM-licensed professionals; composting toilets are allowed as an alternative system but greywater still needs a DEM-approved disposal method. source

Greywater reuse

RestrictedDEM regulates greywater as part of the OWTS system rather than as a freely reusable stream; it generally must go through an approved leachfield or holding tank.

Rainwater harvesting

Generally allowedState law (RIGL § 44-30-28) defines cisterns of 50+ gallons and offers a tax credit for installing one; the plumbing code also addresses nonpotable rainwater systems.

Private wells & water rights

RestrictedRIDOH's Office of Private Well Water Contamination regulates private wells statewide, requiring testing and a Well Completion Report; local building officials may add requirements. source

Living disconnected from utilities

Varies locallyNo state law bans grid disconnection, but occupancy still requires a certificate of occupancy tied to an approved water source and wastewater system, issued by the local building official. source
