Off-Grid Living in Smithfield, Rhode Island

I've been digging through Smithfield, Rhode Island's town and state rules for anyone dreaming of a more self-sufficient setup here, and the short version is: this is a zoned town, and off-grid living gets filtered through both local zoning and Rhode Island's state codes. Here's what I found.

Zoning. Smithfield is not unzoned. The town's Zoning Ordinance, administered under the Town of Smithfield Building & Zoning Department and rooted in Rhode Island General Law Chapter 45-22.2, breaks the town into districts like R-200, R-80, R-20, and OS, each with its own rules on lot size, density, and permitted uses. Before you buy raw land here with off-grid plans, I'd get a zoning certificate from the town, that's the official written determination of what a parcel can and can't be used for.

Dwellings, tiny homes, RVs. I didn't find any Smithfield-specific ordinance addressing tiny homes or RVs as permanent dwellings. The Building & Zoning Department enforces the state building code plus local zoning for all occupancy, so any non-conventional dwelling would need to clear that review. This is genuinely unclear from what's published, so call the Building & Zoning office directly before committing.

Building permits. The Building & Zoning Department enforces the Town Charter, local ordinances, and all state-adopted building, fire, and property maintenance codes. State law requires the town to start reviewing permit applications within 15 calendar days of submission.

Septic and composting toilets. Like most of Rhode Island, Smithfield doesn't run its own septic program, it's the state's RIDEM Office of Water Resources (OWTS Program) that handles site-suitability review, design review, and inspections. Any new septic system needs a DEM-licensed designer and installer. I found no town-level composting toilet allowance, so that's an open question for RIDEM or the town.

Greywater. No Smithfield-specific greywater ordinance turned up in my research. This falls under RIDEM's statewide OWTS framework by default, so treat greywater reuse as state-regulated rather than a local carve-out.

Rainwater harvesting. I found no town restriction on collecting rainwater. This appears to be governed by state-level rules, which are generally permissive, but I'd still confirm nothing local has changed.

Wells. Private wells fall under Rhode Island Department of Health rules statewide; I found no Smithfield ordinance layering on extra restrictions.

Utilities. This is where things tighten up. The Building & Zoning Department enforces state-adopted building codes, and Rhode Island's baseline code generally expects pressurized potable water and, when power lines are close by, a grid electric connection. I found no Smithfield-specific exemption from that. If full utility disconnection is your goal, this is a conversation to have directly with the Building & Zoning office before you plan a build.

Bottom line: Smithfield layers its own zoning and building enforcement on top of Rhode Island's statewide codes for septic, wells, and construction. Several off-grid specifics (tiny homes, composting toilets, full utility disconnection) aren't addressed in anything I could find published, which means they're a "call and ask" situation, not a "it's clearly allowed" situation.
