Off-Grid Living in Grant County, North Dakota

I'll be upfront: Grant County, North Dakota is one of the more "actively zoned" rural counties I've researched, which surprised me a little since a lot of ND counties leave zoning to individual townships. Grant County has its own countywide zoning ordinance, administered by the Grant County Planning & Zoning Department, with the Official County Zoning Map kept on file with the County Auditor. That means if you're eyeing raw land here for an off-grid build, the county itself, not just your township, has a say.

Zoning and building permits. The county's Planning & Zoning Department reviews building permit applications and makes recommendations to the County Commission. Some land uses need a conditional use permit, which requires a public hearing before the Planning Commission. Critically, the county says a building permit is required for pretty much any new structure, home, garage, shed over a small size threshold, deck, patio, porch, or addition, and this applies even to farm residences that are otherwise tax-exempt. The county's own materials say to apply well ahead of construction. I did not find a specific fee schedule in what I reviewed, so confirm current costs and lead times directly with the Planning & Zoning Department.

Dwellings, tiny homes, RVs. I could not confirm specific minimum square footage requirements for dwellings. The county does separately track mobile/manufactured homes through a registration process, so if that's your plan, ask the Planning & Zoning office how it's handled.

Septic and greywater. Septic systems are permitted, but regulated through a mix of state and local health authority. North Dakota's Department of Environmental Quality licenses septic installers statewide and sets design standards, but actual permits come from a local public health unit. I wasn't able to confirm which specific health unit covers Grant County from the sources I had, so that's a call worth making before you dig. Greywater reuse rules I simply couldn't find, at either the county or state level, so treat that as an unclear/gray area and ask the local health unit directly.

Rainwater and wells. No Grant County ordinance specifically restricts rainwater collection; state baseline is generally permissive, though an underground storage tank could still trigger the standard building permit review. Wells for domestic use are permitted and regulated at the state level. Grant County is also served regionally by the Southwest Water Authority for rural water supply, so private well or hookup decisions may intersect with that. Larger, non-domestic water use needs a conditional water permit from the state Department of Water Resources.

Utilities. I found no county rule mandating a grid hookup, which is good news for anyone wanting to live disconnected. The building permit process remains the county's main tool for reviewing any structure, off-grid or not.

Bottom line: Grant County isn't hands-off. Talk to Planning & Zoning early.
