Unincorporated Rice County, Minnesota requires a building permit for every construction project and for demolition, and permitted work is inspected12. County zoning controls where and how you can build, except in Dundas, Faribault, Lonsdale, Morristown, Northfield and Bridgewater Township, which administer their own rules34. Rice County Environmental Health reviews septic designs, issues permits and inspects installations5.

Do you need a building permit in Rice County, Minnesota?
Yes. Every construction project in unincorporated Rice County requires a building permit, as does demolition of an existing structure1. Rice County has adopted and enforces the Minnesota State Building Code for buildings and structures in its jurisdiction9. Permitted residential and commercial work receives field inspections that can include footings, foundations, structural components, heating, plumbing and fireplaces2. Rice County does not administer building or zoning matters in Dundas, Faribault, Lonsdale, Morristown, Northfield or Bridgewater Township, so applicants there must contact the appropriate city or township4.
Who is the Rice County building department, and how do you reach them?
The Rice County Building Division issues building permits and performs inspections in the county-administered area102. Reach the division at the Rice County Government Services Building, 320 Third St. NW, Faribault, MN 55021, or call 507-332-611310. Building permits must be submitted through the county's online permitting system110. Permit fees vary locally and may use fixed charges, construction value or both, so confirm the current amount with the Building Division before applying11.
Does Rice County have zoning?
Yes. Rice County's zoning ordinance sets district regulations, development requirements and environmental protections in the county-administered unincorporated area3. The applicable government varies by location because Dundas, Faribault, Lonsdale, Morristown, Northfield and Bridgewater Township handle their own building and zoning matters4. In the county's Rural Residential district, a single-family lot has a 20,000-square-foot minimum, although sewage-treatment needs can require more land7. Rural Residential setbacks are 40 feet from a county road or state highway, 20 feet from a township or other road, 10 feet at the side and 20 feet at the rear12. Rural Residential property also has a 25% impervious-surface limit, while principal buildings are capped at 35 feet1314. These figures are district-specific, so ask Planning and Zoning to identify the parcel's district and any additional standards before designing the site712.
How do septic permits work in Rice County?
Minnesota counties, cities and townships review designs and issue construction permits for most subsurface sewage treatment systems (SSTS); only large systems built for a flow greater than 10,000 gallons a day go to the state's MPCA instead15. In Rice County, the Environmental Health division of Environmental Services is that local authority: it reviews individual and community wastewater treatment system designs, issues the permits, and inspects installation to confirm code compliance516. Apply for a septic permit or a compliance inspection through the county's online permitting system, or call 507-332-6113 with questions16. Only about 8% of Rice County's soils are rated free of severe limitations for a conventional septic drain field, so budget for a site evaluation and the possibility of an engineered or mound system rather than assuming a standard drain field will pass17. For a truly primitive setup such as a privy, state rule requires following local ordinance for disposing of the waste; where no local ordinance covers it, the material must be buried or covered with soil and kept away from surface water, drainageways and wet areas18.
Can you live in an RV or tiny home on your land in Rice County?
We could not confirm a complete Rice County rule for living in one RV or a tiny home on a private parcel, so ask the Planning and Zoning Division about the proposed use and zoning district before moving onto the land. County zoning standards regulate development in the county-administered area, while five cities and Bridgewater Township apply their own rules34. A manufactured home installed for occupancy in Minnesota must be inspected under federal installation standards, and later alterations require review before work begins19. In Rice County's jurisdiction, a manufactured home or accessory dwelling unit also needs all required inspections—including final approval from the State Electrical Inspector—before a certificate of occupancy is issued and the dwelling is occupied20.
Building a home in Rice County: the steps, in order
- Identify the governing jurisdiction; five cities and Bridgewater Township administer their own building and zoning rules rather than Rice County4.
- Ask Rice County Planning and Zoning to confirm the district, allowed use, lot size, setbacks, height and impervious-surface limit for a county-administered parcel7121314.
- Apply online for the building permit before construction or demolition begins1.
- For a property without sewer service, obtain septic design approval and a permit from Rice County Environmental Health516.
- Secure access approval from MnDOT for a state highway, the Rice County Highway Department for a county road or the township clerk for a township road when a driveway permit is required8.
- Obtain a floodplain permit before placing a house, fill, culvert or bridge in a mapped floodplain21.
- Keep permitted work accessible and exposed through each required inspection, and do not cover work until the building official approves it22.
- Before occupying a manufactured home or accessory dwelling unit, complete the required inspections and obtain the certificate of occupancy20.
What to check before you buy land in Rice County
Soils: only about 8% of Rice County's soil is rated free of severe limitations for a conventional septic drain field, so arrange a site evaluation before assuming a standard system will work17. Zoning: verify the parcel's district because minimum lot area, setbacks, coverage and height vary by district, and sewage treatment can require more than the stated zoning minimum7121314. Flood: a house, fill, culvert or bridge in a mapped floodplain requires a floodplain permit21. Access: driveway approval may come from MnDOT, the Rice County Highway Department or the township clerk according to which road serves the parcel8. Taxes: Rice County's effective property tax rate is about 1%, and the median annual property tax bill is about $2,8992324.
Watch-outs
- Rice County does not handle building or zoning for parcels inside Dundas, Faribault, Lonsdale, Morristown, Northfield or Bridgewater Township; contact the city or township that governs the parcel4.
- Rural Residential dimensions are not countywide defaults; other districts and specific uses can have different standards7121314.
- We could not confirm a complete private-lot RV, tiny-home, minimum dwelling-size or well rule; ask Rice County Planning and Zoning about land use and the appropriate well authority before committing to a site25.
