Off-Grid Living in Murray County, Minnesota

If you're eyeing unincorporated land in Murray County, Minnesota for an off-grid setup, here's what I found digging through the county's own pages and the state rules that sit behind them.

Zoning is countywide and applies to everything, even sheds. Murray County's Environmental Services office (Planning and Zoning Division) requires a zoning certificate for any structure on unincorporated land, and the county's language is explicit that this covers structures "large or small, portable, temporary, or permanent." So you can't just park a camper or build a small cabin without going through the county first. Note that incorporated cities inside the county (like Hadley, partially) may run their own separate zoning, so always confirm which authority governs your specific parcel.

Dwellings, tiny homes, RVs: I couldn't find a Murray County rule that specifically addresses tiny homes or RVs as permanent residences. Given the broad "any structure" language in the zoning certificate requirement, my read is that these would fall under that same permitting umbrella, but this is genuinely unclear and worth a direct call to the Zoning Administrator before you commit.

Building permits and code: Minnesota's State Building Code is the statewide floor, though it's only enforceable locally if adopted by ordinance. Murray County's own housing assistance program materials confirm the county does issue building permits and requires projects to meet "building codes adopted at the time building permit is obtained." I didn't find the specific adoption ordinance, so confirm current code status with the county, and ask about any rural-township reduced-enforcement provisions under state law.

Septic: Handled entirely at the county level under state authority. Murray County enforces the state's Subsurface Sewage Treatment System (SSTS) rules through its own zoning ordinance (Section 12 / Article 25), and property transfers require SSTS compliance. Composting and incinerating toilets remain allowed under the state code that the county ordinance incorporates.

Greywater and rainwater: No county-specific rules turned up in my research for either. Greywater likely falls under the state SSTS rules the county already enforces; rainwater catchment for outdoor use is generally unregulated statewide, with indoor plumbed systems reviewed under state plumbing code. Confirm specifics with Environmental Services.

Wells: Regulated by the state, not the county. The Minnesota Department of Health issues well construction permits under state statute, and licensed contractors handle the paperwork. Murray County's own role is limited to a cost-share program helping landowners seal abandoned wells. Big water users (over roughly 10,000 gallons a day) need a separate DNR permit.

Utilities: I found nothing requiring or banning grid disconnection for a legally permitted dwelling. But since you'll still need a zoning certificate and SSTS compliance regardless, going off-grid doesn't get you out of those two obligations.

Bottom line: Murray County is more hands-on than some rural counties, especially on zoning certificates for any structure. Call ahead before you build anything.
