Building permits, zoning and land rules in Nobles County, Minnesota
47Index Score / 100 #75 of 87 in Minnesota
Unincorporated Nobles County, Minnesota requires a county land-use permit, a zoning approval, before anyone erects, alters or moves a building1. We could not confirm who enforces the State Building Code on rural parcels, so ask before you design2. Zoning and septic permits both come from Nobles County Environmental Services, and incorporated cities fall outside the county zoning rule34.

Do you need a building permit or land-use permit in Nobles County, Minnesota?
Unincorporated Nobles County requires a county land-use permit before a person erects, alters or moves a permanent or portable building1. This is the county's zoning approval, and a completed form and the applicable fee go to the Planning & Zoning Administrator; a conforming project is to receive its land-use permit within 60 days12. The published fee for a new dwelling is $750, while an after-the-fact land-use permit costs triple the listed amount1011. The county's inspections cover setbacks and land use under its zoning ordinance, and the reviewed material does not show county State Building Code inspections13. The Minnesota State Building Code is the statewide minimum construction standard, but we could not confirm who adopts or enforces it for building permits on unincorporated land, so ask Environmental Services214. Minnesota's owner-builder exemption concerns contractor licensing and does not erase required land-use or septic permits8.
Who issues land-use permits and handles building questions in Nobles County, and how do you reach them?
Nobles County Environmental Services is the first office to call for county land-use permits, zoning, subdivision and septic permits154. Inside a city, the county zoning rule does not apply, so ask that city about its own building permits and zoning15. The county office is at 960 Diagonal Road, PO Box 187, Worthington, Minnesota 56143, and its phone number is 507-295-532214. The official state directory also lists ethompson@co.nobles.mn.us as the contact email14. Ask the office to identify the zoning district, required application, fee, septic sequence and floodplain status for the exact parcel12516. A variance, conditional use or zoning amendment follows the ordinance's additional review path rather than the ordinary conforming-permit path12. We could not confirm general building-code permits, inspections or certificates of occupancy, so ask who has that jurisdiction2.
Does Nobles County have zoning?
Yes. Nobles County administers zoning and subdivision regulations in unincorporated areas; incorporated municipalities are outside the stated scope of the county rule3. The parcel's district matters because lot, setback, coverage and height standards vary17181920. In the Rural Residential R-2 District, a private-sewer dwelling generally needs one acre, reducible to one-half acre plus public right-of-way when the stated percolation test is met21. The cited residential setbacks are 100 feet from a state-highway centerline, 100 feet from a county-road centerline and 65 feet from a township-road centerline, subject to the ordinance's exceptions18. Dividing land also triggers county subdivision review and plat requirements22. Confirm the district and whether subdivision review applies with Environmental Services before designing the site1422.
How do septic permits work in Nobles County?
Nobles County Environmental Services administers the county's subsurface sewage treatment system program4. A county SSTS construction permit is required before constructing, installing, modifying, replacing, repairing, operating or expanding the capacity of a septic system, and the permit is valid for one year5. Where an SSTS permit is required, Nobles County requires that permit before issuing a building or land-use permit5. Septic permit fees are separate from the land-use fee: a new Type I or II system is $200, Type III $300 and Type IV $40010. Compliance inspections apply to new and replacement systems and other situations identified in the ordinance, and qualified licensed businesses or certified employees must perform and sign them23. Site feasibility deserves early attention because only about 2.9% of county soils are rated without severe limitations for a conventional septic drain field9. Contact Environmental Services before fixing the house location because the septic design, replacement area and zoning layout need to work together1417.
Can you live in an RV or tiny home on your land in Nobles County, Minnesota?
We could not confirm a general Nobles County rule allowing long-term occupancy of one RV on private land, so ask Environmental Services about duration, utilities and zoning before relying on an RV during construction14. In a floodplain district, an RV must satisfy detailed exemption criteria or be treated as a new structure; the county definition describes an RV as temporary living quarters rather than a permanent dwelling6. Minnesota treats a tiny house as a dwelling of 400 square feet or less, excluding lofts, and subjects it to the State Building Code and local zoning24. We could not confirm a general minimum size for every dwelling, but a manufactured home must be at least 24 feet wide and contain at least 800 square feet7. Manufactured-home accessory dwellings are limited to specified care or farm situations and carry siting conditions25.
How do you build a home in Nobles County, Minnesota? The steps, in order
Ask Environmental Services to confirm county jurisdiction, the zoning district and whether subdivision review is involved14322.
Confirm lot size, setbacks, floodplain limits and legal access before fixing the site plan211816.
Complete the site evaluation, septic design and county SSTS permit before the land-use permit when a new system is required5.
Submit the land-use form and fee to the Planning & Zoning Administrator; a new-dwelling permit is listed at $7501211.
Ask which building official, if any, issues State Building Code permits and inspections for the parcel2.
For access to a state trunk highway, obtain the MnDOT driveway permit before changing the access or property use26.
If acting as owner-builder, confirm the contractor-license exemption without treating it as a permit waiver8.
What should you check before buying land in Nobles County?
Make septic feasibility an early due-diligence item because only about 2.9% of Nobles County soils lack severe limitations for a conventional drain field9. Confirm the zoning district, minimum lot size, setbacks and floodplain overlay with Environmental Services rather than applying one district's standards countywide14211816. Ask whether a boundary change or added lot requires subdivision review22. Verify the road authority and access approval: MnDOT requires a permit for a change in access to its right-of-way or a property-use change affecting that access, while the county material confirms permitted-driveway limits only for certain manufactured-home uses2627. For carrying costs, the effective property-tax rate is about 0.9%, the median annual property-tax bill is about $1,674 and typical annual home insurance is about $1,840282930.
Watch-outs
A Nobles County land-use permit is required, but State Building Code adoption, building permits, inspections and certificates of occupancy remain unconfirmed; ask Environmental Services who has code jurisdiction1214.
The cited one-acre private-sewer lot minimum and road setbacks come from residential district standards, so confirm the parcel's zoning district before using them in a design1718.
After-the-fact land-use permits cost triple the published amount, so secure approval before beginning work11.
We could not confirm a rule for private well permits in Nobles County; ask Environmental Services which office handles new wells14.

“For purposes of this ordinance, Nobles County is hereby divided into the following Zoning Districts:”
Minimum lot sizeSpecified
Residential lots in Nobles County zoning districts, including districts with private or central sewer and water systems.
Requirements vary by zoning district, dwelling type, sewer/water service, and shoreland classification.
For one cited residential standard, private-sewer dwelling lots require one acre unless a qualifying percolation test permits one-half acre, and the lot must accommodate two standard septic soil treatment areas.
private-sewer minimum lot size: 1 acre (may be reduced to one-half acre if soil percolation is faster than 60 minutes per inch and two standard septic soil treatment areas can be located) · residential lot coverage in cited district: <= 40 percent
“For dwelling units with private sewer systems, the minimum lot size shall be one (1) acre, unless it can be demonstrated by taking a soils percolation test that the percolation rate of the soil is faster than 60 min. per inch, in which case the lot may be reduced to one-half (½) acre plus the public right-of-way.”

“For dwelling units with private sewer systems, the minimum lot size shall be one (1) acre, unless it can be demonstrated by taking a soils percolation test that the percolation rate of the soil is faster than 60 min. per inch, in which case the lot may be reduced to one-half (½) acre plus the public right-of-way.”
SetbacksSpecified
Buildings in the cited county residential district standards.
Front setbacks are measured from road centerlines: 100 feet from state highways, 100 feet from county roads, and 65 feet from township roads.
If those standards are impracticable, the average setback of existing buildings applies, but never less than 20 feet from the road right-of-way.
The two-lane sections of T.H. 60 require 225 feet from the centerline.
Interior side and rear setbacks are each at least 10 feet; corner lots require front setbacks on each road.
state highway front setback: 100 ft · county road front setback: 100 ft · township road front setback: 65 ft · interior side setback: >= 10 ft · rear setback: >= 10 ft
“100 ft. State Highway 100 ft. County Road 65 ft. Township Road”
Lot coverageSpecified
Lot coverage in Nobles County zoning districts.
Coverage limits vary by district and use.
The cited residential standard limits buildings for residential use to 40 percent of the lot or tract; another cited district limits building coverage to 50 percent.
residential building lot coverage: <= 40 percent · other cited district building lot coverage: <= 50 percent
“Lot coverage - not more than forty (40) percent of the lot or tract shall be occupied by buildings for residential use.”

maximum building height in cited district: <= 35 feet (chimneys and church spires)
“No building hereafter erected shall exceed two and one-half (2 ½) stories or thirty-five (35) feet in height. This height limitation shall not apply to chimneys and church spires.”
Living in an RVLimited
Placement and occupancy of recreational vehicles in floodplain districts governed by the Nobles County Zoning Ordinance in unincorporated Nobles County.
A recreational vehicle in the floodplain must either satisfy the ordinance's exemption criteria or be treated as a new structure subject to the ordinance.
Exempt placement is limited to individual lots or parcels of record, existing commercial recreational vehicle parks or campgrounds, or existing condominium-type associations.
The vehicle must have a current highway-use license, be highway ready and attached only by quick-disconnect utilities, have no permanent structural additions, and be permissible in the pre-existing underlying zoning district.
Accessory structures are not permitted in the Floodway District; accessory structures in the Flood Fringe District must use flood-resistant materials and be securely anchored, and must constitute a minimal investment.
An exempt recreational vehicle loses its exemption when site development exceeds a minimal investment; it is then treated as a new structure subject to elevation and floodproofing requirements, and improvements may not hinder removal during flooding.
New commercial recreational vehicle parks or campgrounds, subdivisions or condominium associations, and expansions of similar existing uses exceeding five units or dwelling sites may be allowed subject to additional requirements.
For a new or replacement site in the Flood Fringe District, the vehicle and contents must be on fill at or above the regulatory flood protection elevation with adequate road access.
A new or replacement site in the Floodway District, or an alternative Flood Fringe placement, may be allowed as a conditional use under the ordinance and Section 10.4.
Conditional-use applications require an emergency evacuation plan acceptable to the County Board, protected or flood-resistant sewage and water facilities, and any floodway fill must not increase the regional flood stage.
The ordinance defines a recreational vehicle as designed primarily for temporary living quarters for recreational, camping, travel, or seasonal use, not as a permanent dwelling.
recreational vehicle maximum area: <= 400 square feet (measured at the largest horizontal projection) · expansion threshold: > 5 units or dwelling sites (new commercial RV parks or campgrounds, subdivisions or condominium associations, and similar expansions) · regulatory flood protection elevation: at or above (required for new or replacement recreational vehicle sites in the Flood Fringe District) · regional flood stage increase from floodway fill: false (floodway fill must not increase the regional 1% chance flood stage)

“SSTS Permit applications shall be made on forms provided by the Environmental Services Department and signed by the applicant and an appropriately certified practitioner including the practitioner’s certification number and date of expiration.”
An owner of residential real estate who personally builds or improves residential real estate, as an exemption from the residential contractor licensing requirement.
The owner must occupy or intend to occupy the residential real estate for residential purposes, or retain ownership for rental purposes after completion.
The exemption does not apply when the owner constructs or improves residential real estate for resale or speculation.
An owner is presumed to be building or improving for speculation if the owner constructs or improves more than one property within any 24-month period, unless the properties will be retained for rental purposes.
This is a contractor-licensing exemption and does not waive applicable building permits, inspections, or certificates of occupancy.
speculation presumption threshold: > 1 additional property within 24 months (The presumption does not apply if the properties will be retained by the owner for rental purposes.)
“The license requirement does not apply to: [...] an owner of residential real estate who builds or improves residential real estate”
Building code adoptedAdopted (with conditions)

Adopted — Buildings governed by the Minnesota State Building Code in Nobles County.
“The State Building Code is the standard that applies statewide for the construction, reconstruction, alteration, repair, and use of buildings and otherstructures of the type governed by the code.”
Certificate of occupancyLimited
Use or occupancy of buildings and structures, and changes in existing occupancy classification, in Minnesota jurisdictions administering and enforcing the State Building Code.
A building or structure may not be used or occupied, and an existing occupancy classification may not be changed, until the building official issues a certificate of occupancy under Minnesota Rules part 1300.0220.
The rule applies through the building official and therefore depends on the relevant jurisdiction administering and enforcing the State Building Code.
Issuance of a certificate of occupancy is not approval of a violation of the code or other municipal ordinances; a certificate purporting to authorize violation or cancellation of those requirements is invalid.
A municipality has the option of requiring certificates of occupancy for U occupancies constructed under the International Building Code, accessory structures constructed under the International Residential Code, and used manufactured homes moved into or within a jurisdiction.
Legal occupancy of a structure existing on the date of code adoption may continue without change.
A temporary certificate may be issued before all permitted work is complete if the occupied portion can be occupied safely; the building official sets its validity period.
optional certificate category: U occupancies constructed under the International Building Code (municipality has the option of requiring a certificate) · optional certificate category: accessory structures constructed under the International Residential Code (municipality has the option of requiring a certificate) · optional certificate category: used manufactured homes moved into or within a jurisdiction (municipality has the option of requiring a certificate)
“No building or structure shall be used or occupied, and no change in the existing occupancy classification of a building, structure, or portion of a building or structure shall be made until the building official has issued a certificate of occupancy for the building or structure under this part.”
Camping on your landLimited
Private or public areas accommodating five or more tents or recreational camping vehicles on a daily, nightly, weekly, or longer basis
An annual license from the Minnesota Department of Health is required before establishing, maintaining, conducting, or operating a recreational camping area.
The license requires application, payment of the statutory fee, and approval for operation including plan review.
A recreational camping area excludes children's camps, industrial camps, migrant labor camps, United States Forest Service camps, state forest service camps, qualifying state wildlife-management or state-owned public-access areas, qualifying temporary holding areas adjacent to motorsports facilities, and a privately owned area used by a private club no more than once annually and no longer than seven consecutive days.
A special event recreational camping area operates no more than two times annually and for no more than 14 consecutive days.
The statute does not resolve local zoning or land-use requirements.
minimum accommodated tents or recreational camping vehicles: >= 5 units (Statutory exclusions apply.) · special event operating frequency: <= 2 times annually (Special event recreational camping area.) · special event duration: <= 14 consecutive days (Special event recreational camping area.) · annual license base fee for recreational camping area with 24 or fewer sites: 100 USD (Additional $8 per licensed site; special event areas are excluded from that per-site paragraph.) · annual license base fee for recreational camping area with 25 to 99 sites: 410 USD (Additional $8 per licensed site; special event areas are excluded from that per-site paragraph.) · annual license base fee for recreational camping area with 100 or more sites: 610 USD (Additional $8 per licensed site; special event areas are excluded from that per-site paragraph.)
“"Recreational camping area" means any area, whether privately or publicly owned, used on a daily, nightly, weekly, or longer basis for the accommodation of five or more tents or recreational camping vehicles free of charge or for compensation. [...] "Special event recreational camping area" means a recreational camping area which operates no more than two times annually and for no more than 14 consecutive days. [...] No person, firm or corporation shall establish, maintain, conduct or operate a manufactured home park or recreational camping area within this state without first obtaining an annual license from the state Department of Health.”
Tiny homesLimited
Construction and residential use of tiny houses statewide, subject to the Minnesota State Building Code and applicable municipal zoning ordinances.
The Minnesota State Building Code applies statewide to construction of buildings, including tiny houses.
Municipal zoning ordinances vary by municipality and regulate land use, location, height, width, foundation type, number of stories, and building size.
The jurisdiction must be consulted for local zoning specifics.
Tiny houses used as dwelling units must comply with the Minnesota Residential Code unless otherwise stated in Appendix Q.
A tiny house is a dwelling of 400 square feet or less in floor area, excluding lofts.
Applicable requirements include light, ventilation, heating, minimum room sizes, ceiling heights, sanitation, toilet, bath and shower spaces, emergency escape and rescue openings, means of egress, smoke alarms, and carbon monoxide alarms.
“The Minnesota State Building Code is the standard of construction that applies statewide for the construction of buildings (MS 326B.121) including tiny houses.”
Well permitLimited
Construction of water-supply, dewatering, and environmental wells in Minnesota.
A well notification and applicable filing fee are generally required before construction; the statute describes notification rather than a general construction-permit requirement for these wells.
A drive-point water-supply well personally constructed by an individual on owned or leased property for farming, agricultural purposes, or the individual's place of abode must be reported within ten days after completion, and no notification fee may be charged.
The notification requirement preempts local permits and notifications unless the commissioner has delegated permitting or notification authority under section 103I.111.
If operation of the well requires a Minnesota Department of Natural Resources appropriation permit, specified information must be submitted to the commissioner of natural resources and construction may begin after preliminary approval.
A well that is not in use must be sealed or have a maintenance permit, subject to the statutory environmental/dewatering-well exception.
drive-point well notification deadline: 10 days after completion (personally constructed by an individual on owned or leased property for farming, agricultural purposes, or the individual's place of abode) · unused well status: sealed or maintenance permit (environmental or dewatering wells not sealed by 14 months after completion require an annually renewed maintenance permit)
“Except as provided in paragraph (d), a person may not construct a water-supply, dewatering, or environmental well until a notification of the proposed well on a form prescribed by the commissioner is filed with the commissioner with the filing fee in section 103I.208, and, when applicable, the person has met the requirements of paragraph (e).”
Agricultural exemptionAvailable (with conditions)
Agricultural buildings statewide that meet the definition in Minnesota Statutes § 326B.103, subdivision 3.
The structure must be on agricultural land as determined by the governing assessor for the municipality or county under section 273.13, subdivision 23.
The structure must be designed, constructed, and used to house farm implements, livestock, or agricultural products under section 273.13, subdivision 23.
The building must be used by the owner, lessee, and sublessee and members of their immediate families, employees, and persons engaged in pickup or delivery of agricultural products.
The State Building Code does not apply except with respect to state inspections required or rulemaking authorized by sections 103F.141, 216C.19, subdivision 9, and 326B.36.
Translucent panels or other skylights without raised curbs must be supported to have equivalent load-bearing capacity as the surrounding roof.
“The State Building Code is the standard that applies statewide for the construction, reconstruction, alteration, repair, and use of buildings and other structures of the type governed by the code. [...] (c) The State Building Code does not apply to agricultural buildings except: (1) with respect to state inspections required or rulemaking authorized by sections 103F.141; 216C.19, subdivision 9; and 326B.36; and (2) translucent panels or other skylights without raised curbs shall be supported to have equivalent load-bearing capacity as the surrounding roof.”
county zoning authorityLimited
County planning and zoning authority over unincorporated areas of Minnesota.
The authority applies to a county having less than 300,000 population according to the 1950 federal census.
The statute authorizes county planning and zoning activities generally within the qualifying counties; it does not identify a separate unincorporated-area limitation in this section.
Except as otherwise provided, a county regardless of population must not enact, amend, or enforce an ordinance eliminating or terminating a lawful use by amortization.
The amortization prohibition does not apply to adults-only bookstores, adults-only theaters, or similar adults-only businesses as defined by ordinance.
The amortization subdivision does not prohibit nuisance-prevention or nuisance-abatement enforcement or elimination of a use determined to be a public nuisance without payment of compensation.
population threshold: < 300000 persons (According to the 1950 federal census)
“having less than 300,000 population according to the 1950 federal census is authorized to carry on county planning and zoning activities.”
county building authorityGeneral
Minnesota counties may administer and enforce the State Building Code within their jurisdiction by ordinance; this includes a county's authority over residential construction in unincorporated county territory, subject to the statutory limits on code application and local provisions.
The statutory authorization is to administer and enforce the State Building Code, rather than a county-specific building code.
A county that is not already required by Minnesota Statutes § 326B.121, subdivision 2(a), to administer and enforce the code may elect to do so by ordinance.
The State Building Code applies statewide to construction, reconstruction, alteration, repair, and use of buildings and structures governed by the code.
The State Building Code does not apply to agricultural buildings except for state inspections or rulemaking authorized by Minnesota Statutes §§ 103F.141, 216C.19, subdivision 9, and 326B.36, and except that translucent panels or other skylights without raised curbs must have equivalent load-bearing capacity as the surrounding roof.
A municipality may not require building-code provisions regulating structural components or systems that differ from the State Building Code; with state building official approval, it may adopt a more restrictive ordinance where geological conditions warrant it.
A municipality may enforce the State Building Code through lawful means, including contracts with other municipalities or qualified individuals; building-permit fees may be retained or remitted to reimburse them.
“If a municipality is not required by paragraph (a) to administer and enforce the State Building Code, the municipality may choose to administer and enforce the State Building Code within its jurisdiction by adopting the code by ordinance.”
