Unincorporated Yellow Medicine County, Minnesota requires a county land-use permit for a new building or structure, an addition, or a structure moved onto land12.

Do you need a building permit in Yellow Medicine County, Minnesota?
Yes—a Yellow Medicine County land-use permit is required for new construction of a building, structure or accessory structure, for an addition, and for a structure moved onto a property12. The rule includes houses, garages, storage sheds, decks, porches, signs, grain bins and barns2. Replacing windows, siding or shingles and doing interior remodeling do not require that county land-use permit12. This is a land-use approval; the reviewed county information does not establish whether Yellow Medicine County also administers building-code permits or inspections. Ask the Land and Resource Management Office which approvals apply to the exact project before work begins2. Minnesota's State Building Code is the statewide standard for covered buildings, with limited treatment of agricultural buildings, but local enforcement depends on the applicable statutory and local arrangement7.
Who handles Yellow Medicine County building permits, and how do you reach them?
The Yellow Medicine County Land and Resource Management Office handles planning, zoning and county land-use permits rather than a separately listed county building department2. The office is at 1000 10th Ave. Suite #2, P.O. Box 675, Clarkfield MN 56223; call 320-669-75242. Permit applications may be requested by phone or completed in person in Clarkfield2. Published land-use permit fees are based on construction cost, so ask the office to confirm the current fee and required application materials for the project2. A qualifying owner who personally builds or improves residential real estate may use Minnesota's contractor-licensing exemption when the property will be occupied or retained as a rental, but the exemption does not cover work for resale or speculation and does not waive permits6.
Does Yellow Medicine County have zoning?
Yes. Yellow Medicine County's land-use ordinance regulates uses and development in the county's unincorporated areas32. That makes the parcel's zoning district central to questions about allowed uses, setbacks, lot standards, RV occupancy and tiny homes. The reviewed information does not establish one countywide numerical setback, minimum lot size, minimum dwelling size, building-height limit or lot-coverage limit. Ask the Land and Resource Management Office to identify the parcel's district and every site standard before designing or buying2. Some proposals may need a conditional-use permit or variance under the county ordinance3. Flood-prone land needs another check: Minnesota requires a local floodplain permit for a house, fill, culvert or bridge in applicable floodplain areas8. The county says some areas fall under its floodplain ordinance, so bring the parcel map and proposed building location to the same office2.
How do septic permits work in Yellow Medicine County?
Yellow Medicine County requires a sewer permit before installing, constructing, replacing, modifying, altering, repairing or expanding the capacity of a sewage treatment system45. The Land and Resource Management Office administers the county SSTS program and provides sewer permits95. Call 320-669-7524 or visit 1000 10th Ave. Suite #2 in Clarkfield to start5. Only 3.1% of county soils are rated without severe limitations for a conventional septic drain field, so soil evaluation and system design should be early feasibility work rather than an afterthought10. Minnesota local governments issue construction permits for most SSTS, while a large system designed for more than 10,000 gallons per day requires MPCA permitting11. We could not confirm a general county septic-inspection rule or whether a proposed off-grid sanitation method is acceptable; ask the SSTS office before relying on a privy, composting toilet or holding arrangement5.
Can you live in an RV or tiny home in Yellow Medicine County?
We could not confirm a countywide rule allowing full-time RV occupancy on a private Yellow Medicine County parcel. Ask the Land and Resource Management Office whether the parcel's district, sanitation plan and proposed duration allow the use before placing or occupying an RV2. Minnesota's recreational-camping-area license applies to an area accommodating 5 or more tents or recreational camping vehicles and does not answer whether one owner may live in one RV on private land12. A distinct Yellow Medicine County tiny-home occupancy rule and a general minimum dwelling size also could not be confirmed. A tiny home that is a new building or a structure moved onto land still requires county land-use review, and residential use must satisfy the applicable zoning and septic rules134. New manufactured homes installed for occupancy in Minnesota require inspection under the federal installation standards programs13.
Building a home in Yellow Medicine County: the steps, in order
- Ask the Land and Resource Management Office to identify the parcel's zoning district, allowed residential use, setbacks, floodplain status and application requirements32.
- Test septic feasibility early because only 3.1% of county soils are rated without severe limitations for a conventional drain field, then obtain the county sewer permit before covered SSTS work104.
- Apply for the county land-use permit before constructing the house or moving a structure onto the property12.
- Ask the office whether separate State Building Code review, inspections or an occupancy approval applies, because county administration of those items could not be confirmed2.
- If the driveway meets a public highway, obtain the road authority's permit; the County Highway Department publishes an entrance-driveway form for county-road access1415.
- Obtain a local floodplain permit before a house, fill, culvert or bridge project in an applicable floodplain8.
What should you check before buying land in Yellow Medicine County?
Confirm that county zoning governs the parcel and have Land and Resource Management identify the district, allowed use and site standards in writing32. Check septic feasibility before treating vacant land as buildable because only 3.1% of county soils are rated without severe limitations for a conventional drain field10. Check floodplain maps and the proposed building pad because houses, fill, culverts and bridges in applicable floodplain areas require a local permit8. Verify legal road access and ask the relevant road authority about a driveway permit; the county publishes an entrance-driveway form for county highways1415. We could not confirm the applicable residential well-permit authority or a general utility-connection requirement, so ask Land and Resource Management which water authority serves the parcel2. For carrying costs, the effective property-tax rate is about 1%, and the median annual property-tax bill is about $1,5451617.
Watch-outs
- A county land-use permit is required for barns and other listed accessory structures; do not assume an agricultural building is exempt from county land-use review12.
- Only 3.1% of Yellow Medicine County soils are rated without severe limitations for a conventional septic drain field, so septic feasibility can change the build plan10.
- County building-code administration, inspections, occupancy approval, RV living, tiny-home occupancy and numerical zoning standards could not be confirmed; take the parcel and project details to Land and Resource Management2.
