Off-Grid Living in Garrett County, Maryland

I've been digging into Garrett County, Maryland for anyone dreaming of an off-grid spot in the Appalachian highlands, and it's an unusually interesting case: this is one of the few Maryland counties with no countywide zoning ordinance.

Zoning: Outside the eight incorporated towns (Oakland, Accident, Mountain Lake Park, Grantsville, Loch Lynn Heights, Friendsville, Kitzmiller) and the Deep Creek Lake Watershed Zoning Ordinance area, Garrett County itself doesn't regulate land use through zoning. That's genuinely rare, and it means raw-land occupancy has more room to breathe here than in most counties I've researched. But don't get too excited: the county's Subdivision Ordinance, Floodplain Management Ordinance, and Sensitive Area Ordinance still apply everywhere, and towns and the Deep Creek watershed run their own rules. Confirm your parcel's status with the Department of Planning & Land Management before assuming freedom from zoning.

Building & dwellings: The county's Permits & Inspections Division enforces its adopted building code (built on the 2021 IBC/IRC/IECC, with Maryland's statewide building standards layered on top). A permit is required, and if you don't start construction within the code's stated window, the permit lapses. Tiny houses on wheels and long-term RV living aren't spelled out on the county's official pages I found, so I'd call before assuming either is a clear path.

Septic and greywater, this is the big one: Garrett County is unusual in having its own state statute backing septic enforcement, and it's stricter than the norm. The Health Department must issue a permit before any dwelling is built or a mobile home is sited, and building without one is a real violation, not just a paperwork problem. Even more notably, county code defines "sewage" to include sink, dishwater, laundry, and bathwater, not just toilet waste, which sweeps greywater into the same permitting requirement as full septic, going further than Maryland's statewide greywater reuse allowance. I did not find an official page describing a lighter-touch greywater reuse process here, so treat greywater as regulated until the Health Department tells you otherwise.

Rainwater: I found no county restriction on collecting rainwater. The county's stormwater rules reference the same Maryland environmental design standards used statewide, so this looks like the inherited state baseline, permitted.

Wells: Well permits are handled locally by the Health Department under state authority, standard practice in Maryland. Bigger withdrawals need a separate Maryland Department of the Environment appropriation permit.

Utilities: No standalone ordinance on going off-grid from electric or water utilities was found. In practice, though, the sewage permit requirement functions as the real gatekeeper for any occupied structure, off-grid or not.

Bottom line: Garrett County gives you more zoning freedom than almost anywhere else in Maryland, but its septic and greywater rules are tighter than you might expect. Confirm both before you buy or build.
