Off-Grid Living in Cumberland, Rhode Island

I've been digging into what off-grid living actually looks like in Cumberland, Rhode Island, and the short version is: this is a zoned New England town, not a place where you can just buy raw land and start homesteading without paperwork. Here's what I found, organized by the questions people usually ask me.

Zoning. Cumberland is fully zoned under its Code of Ordinances (Appendix B), administered by the town's Building & Zoning Department. The most land-friendly zones are the agricultural districts, A-1 (minimum five acres) and A-2 (minimum 80,000 square feet), but even there you're working within a use table, not a blank check. Bare land doesn't automatically come with a right to occupy it; you need an approved structure and, in most cases, a permit.

Dwellings, tiny homes, RVs. The zoning ordinance generally limits a lot to one main residential building plus a capped number of accessory buildings (except in the A zones). I didn't find any Cumberland provision that lets someone live in an RV or mobile home outside a recognized manufactured-home park, so I'd treat that as off the table unless the Building & Zoning Department tells you otherwise.

Building permits. All construction runs through the town's Building Department, and as of recently they've moved to an online-only permitting system (OpenGov) rather than paper applications. The Building Official also enforces zoning and kicks variance or special-use requests to the Zoning Board of Review.

Septic and composting toilets. I couldn't find a Cumberland-specific composting toilet allowance. Septic systems (what the state calls OWTS) are approved through Rhode Island DEM, with the town Building Department also requiring a permit for any structure served by one. This is a state-controlled area that the town enforces on top of.

Greywater and rainwater. No town-specific greywater ordinance turned up, so state DEM rules would govern. Rainwater harvesting looks fine, I found nothing in Cumberland's code restricting it, so the general state-permissive baseline applies.

Wells and utilities. Private wells fall under state (RIDOH) regulation, not a separate Cumberland restriction, but whether a lot has town water or sewer does affect the dimensional requirements you must meet to build at all. Going fully off-utility-grid isn't clearly protected here. There's a wrinkle worth knowing: some older, undersized lots may still be buildable if they predate the town's first zoning ordinance from 1952, which is exactly the kind of parcel-specific question the Building Department needs to answer for you directly.

Bottom line: Cumberland isn't hostile to rural living, especially in its A-1/A-2 districts, but it's a fully zoned town layered on top of state environmental rules, so plan on calling the Building & Zoning Department before you buy land or start building.
