Off-Grid Living in Richmond, Rhode Island

I've been digging into what it actually takes to live off-grid in Richmond, Rhode Island, and the short version is: this is zoned territory, and the town, county-level state agencies, and Rhode Island's own statewide rules all have a say. There's no single "off-grid ordinance" here, so what you're really navigating is a stack of overlapping requirements.

Richmond is not unzoned. The town has its own Zoning Ordinance (Title 18 of the Code of Ordinances), a zoning map, and a Zoning Board of Review, all run through the town's Building, Planning & Zoning Department. That matters because raw land here isn't a blank slate. Richmond has multiple zoning districts, including an Aquifer Protection Overlay District that limits density to one dwelling per three acres in sensitive watershed and wellhead areas, plus special mixed-use districts along the Route 138/I-95 corridor that require Planning Board review. Lot size, frontage, and setback rules are set town-wide by ordinance, so before you buy land, I'd call the Building, Planning & Zoning Department to find out which district you're in.

On dwellings, I couldn't find any Richmond-specific carve-out for tiny homes or RVs as permanent residences. The Building Office enforces the state Building Code alongside local zoning, and the state baseline generally doesn't treat RVs as legal primary dwellings outside narrow exceptions. Treat this as restricted until you confirm otherwise with the town.

Building permits go through Richmond's Building Office, which enforces the state Building Code per the town charter and zoning ordinance. Expect to submit scaled plans (foundation, floor plan, framing, elevations) plus a plot plan showing setbacks and septic location. Fire department review is part of the process for new construction too.

Septic is a state matter here: Rhode Island DEM licenses the designers and installers of onsite wastewater treatment systems (OWTS) and oversees site suitability, design, and installation. Richmond's own permit process just requires you to show septic location on your plot plan. I found nothing confirming composting toilets as a standalone legal substitute for a permitted septic system, so don't assume that shortcut works here.

Greywater reuse isn't addressed by any Richmond-specific rule I found, so it falls under RIDEM's statewide OWTS framework. Rainwater harvesting looks fine, no Richmond ordinance restricts it, and Rhode Island's state baseline actually permits it.

Private wells are regulated by the RI Department of Health statewide, and Richmond's Aquifer Protection Overlay District boundaries are tied directly to state-mapped wellhead protection areas, so where you can drill may be constrained by which zone you're in.

Finally, going fully off-grid, disconnected from electric and water utilities, isn't something I found an exemption for in Richmond. The Building Office enforces the state Building Code with no noted off-grid variance, so plan on confirming this directly with them before committing to a design.
