Do you need a building permit in Mower County, Minnesota?
Unincorporated Mower County requires a county zoning permit to construct or place any structure where county zoning applies.1 Published zoning fees are $75 for agricultural or accessory structures and $150 for residential structures; after-the-fact permits cost 1.5 times the base fee.1213 Conditional-use, variance and rezone applications each cost $600 plus $46 and use separate application packets and public-hearing processes.1214
The Minnesota State Building Code applies statewide to covered buildings, with local enforcement determined by jurisdiction.15 Code-regulated construction, alteration, repair, moving, demolition and occupancy changes require the applicable building official’s permit.2 Permitted work must remain exposed until inspected and approved; the person doing the work must notify the building official when ready and make an inspection record card available.16 Code-governed buildings generally require a certificate of occupancy before use, with limited exceptions and temporary certificates for safe portions.17 Agricultural buildings are generally exempt from the state code, subject to specified state inspections, rulemaking and skylight-support requirements; Mower County’s zoning-permit requirement still applies.181
Who handles Mower County building permits and zoning applications?
Mower County Environmental Services handles county zoning and land-use permits, septic systems, water planning and floodplain management.3 The office is at 1105 8th Ave NE, Austin, MN 55912; call 507-437-7718 or email zoning@co.mower.mn.us.3 Completed county zoning applications and drawings may be emailed to that address.14 A county-administered building-inspection program could not be confirmed; ask Environmental Services to identify the building official serving the parcel.3
A Mower County owner building or improving residential property for personal occupancy or continued rental ownership may qualify for Minnesota’s residential-contractor license exemption; building for resale or speculation does not qualify.9 Improving more than one property within a 24-month period creates a presumption of speculation unless the properties will be retained for rental.19 The license exemption does not waive zoning permits, applicable building-code requirements or septic approvals.20
Does Mower County have zoning?
Mower County zoning applies outside incorporated municipal limits; Austin sets its own zoning inside city limits.65 Mower County Environmental Services remains the county septic authority, including for systems in municipally sewered areas.421
Mower County has district-specific uses and dimensional standards, plus shoreland and floodplain overlays.22 In the Rural Residence (R-1) District, lots generally need at least 1 acre, 125 feet of width and 200 feet of depth, with a 25-foot front setback from the right-of-way, 5-foot side yards and a 20-foot rear yard, subject to ordinance exceptions.23 The cited height provision caps nonagricultural buildings at 35 feet and exempts agricultural buildings.24 Rural Management (RM) incorporates Agricultural District lot, yard, setback, access and height requirements and their exceptions, including a 40-foot front setback and 20-foot side and rear setbacks.2526
Dwellings are prohibited in wetlands and floodways, and the ordinance restricts dwellings on peat or muck soils.27 Ask Environmental Services to confirm the parcel’s district, overlays and applicable exceptions before choosing a house site.3
How do septic permits work in Mower County?
Mower County Environmental Services administers septic permitting and inspections.4 Covered installations, alterations, repairs and extensions need a county permit, valid for 12 months with a possible extension of up to 6 months.7 The published construction-permit fee is $550 for Type I, II or III residential systems up to 2,500 gallons per day; other systems require the full fee schedule.28
New systems require inspection, and a property transfer triggers compliance inspection when no current Certificate of Compliance is on file.2930 Zoning applications also trigger inspection in shoreland areas, on undersized lots, and for systems at least 20 years old without a current certificate; bedroom or qualifying water-use increases are additional triggers.30 Only about 1.3% of mapped Mower County soils are rated without severe limitations for a conventional drain field, so evaluate septic feasibility before fixing the house location.31
Existing septic systems in municipally sewered areas must remain compliant, with inspection by a licensed inspector at the owner’s expense.32 A failed inspection requires sewer connection unless the municipality confirms in writing that service cannot be provided; a septic replacement may then be allowed.21 Holding tanks cannot continue there without a written municipal exception.33
Can you live in an RV or tiny home in Mower County?
A Mower County rule allowing residential or long-term RV occupancy on a private parcel could not be confirmed. Ask Environmental Services whether the use is allowed in the parcel's zoning district and what sewage arrangement is acceptable before moving an RV onto the land.3
A tiny house used as a dwelling must comply with the Minnesota Residential Code, while local zoning decides whether the use and location are allowed.8 Mower County requires a zoning permit to construct or place a structure where county zoning applies.34 A countywide minimum dwelling size could not be confirmed; ask Environmental Services about the parcel's district before choosing a design.3 A general off-grid sanitation allowance could not be confirmed.35
Building a home in Mower County: the steps, in order
Confirm whether county or municipal zoning applies, then ask Environmental Services for the zoning district, overlays, allowed use and site standards.63
Arrange septic evaluation and design early because only about 1.3% of county soils are rated without severe limitations for a conventional drain field.31
Identify the applicable building official and confirm the building-code permit requirements before starting.23
Submit the county zoning application and drawings; separate packets apply to conditional uses, variances and rezones.36
Check the county floodplain overlays; new structures, land uses, construction, expansion, conversion and structural alterations there must comply with the floodplain ordinance.37
Arrange required inspections for permitted work, keep it exposed until approval and obtain required occupancy approval before moving in.1617
If the driveway connects to a county highway, use the Highway Department's GeoPermits service.11
What should you check before buying land in Mower County?
Start by confirming whether county or municipal zoning applies, then obtain the parcel's zoning district and overlay information.6 Test septic feasibility before treating a rural lot as buildable because only about 1.3% of county soils are rated without severe limits for a conventional drain field.31 Check the floodplain overlays because new structures and other development there must comply with the county floodplain ordinance, and critical facilities are prohibited in those districts.37
Verify legal road access and contact the correct road authority because added access to a public highway is subject to regulation and a permit from that authority.38 Mower County's Highway Department offers county driveway and access applications through GeoPermits.11 Minnesota generally requires state notification and a filing fee before water-supply well construction, with exceptions and possible delegated local authority; ask Environmental Services who administers the parcel’s well requirements.103 The median property-tax bill is about $1,819 per year.39
Watch-outs
A Mower County zoning permit does not resolve building-code permit and inspection requirements; ask Environmental Services to identify the applicable building official.123
Only about 1.3% of mapped county soils are rated without severe limitations for a conventional septic drain field, so make onsite-wastewater feasibility an early purchase contingency.31
New structures and other development in Mower County floodplain overlay districts must comply with the county floodplain ordinance.37
Dwellings are not permitted in wetlands or floodways under the Mower County zoning ordinance, so confirm the parcel's classification before you buy.27

The State Building Code supersedes the building code of any municipality.
The State Building Code does not apply to agricultural buildings except for the state inspections and rulemaking identified in Minnesota Statutes section 326B.121, subdivision 1, paragraph (c), clause (1), and the structural-support requirement for translucent panels or other skylights without raised curbs in clause (2).
The 2020 Minnesota State Building Code is effective March 31, 2020, except the Minnesota Mechanical Fuel Gas Code, which is effective April 6, 2020.

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.

Limited — Accessory dwelling units statewide, including conversion of a structure into an ADU, subject to local zoning and Minnesota residential building-code requirements.
“Local zoning ordinances dictate if a tiny home or accessory dwelling unit (ADU) is allowed on the property.”
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).”

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.”

Subdividing landRegulated (with conditions)
Subdivision regulation by Minnesota municipalities that adopt subdivision regulations under Minnesota Statutes section 462.358.
A municipality may adopt subdivision regulations by ordinance; the statute does not establish one uniform ordinance applicable to every municipality.
Regulations may apply only to certain classes or kinds of subdivisions and must be uniform for each class or kind.
A municipality may extend its subdivision regulations to unincorporated territory within two miles of its limits, subject to the statutory exception for towns that have adopted subdivision regulations.
Regulations may address lot size, location, grading, improvements, utilities, site planning, floodplains, shorelands, soils, water, vegetation, energy, air quality, and geologic and ecological features.
Regulations may prohibit certain classes or kinds of subdivisions when consistent with the comprehensive plan and statutory purposes.
All subdivisions creating five or more lots or parcels that are 2-1/2 acres or less in size must be platted when subject to the municipal subdivision regulations.
municipal extension distance: <= 2 miles (Unincorporated territory; not in a town which has adopted subdivision regulations.) · mandatory platting threshold: >= 5 lots or parcels (Each lot or parcel is 2-1/2 acres or less in size.) · maximum parcel size for mandatory platting: <= 2.5 acres (Applies to subdivisions creating five or more lots or parcels.)
“a municipality may by ordinance adopt subdivision regulations establishing standards, requirements, and procedures for the review and approval or disapproval of subdivisions.”
Driveway accessRequired
Direct driveway connections to or from Minnesota state highways and work within MnDOT right-of-way.
A permit is required before constructing or modifying a direct driveway connection to or from a state highway.
The requirement covers agricultural, single-family residential, commercial, industrial, recreational, public, institutional, natural-resource, and multiple-family residential uses, and privately owned streets.
A new driveway, including a temporary driveway, requires a permit.
Modifying an existing driveway or changing its use or major traffic pattern may require a new permit.
The application should be submitted by the property owner; an agent, tenant, contractor, or developer must include written authorization from the owner.
This claim does not establish driveway-permit requirements for roads outside MnDOT jurisdiction.
“A MnDOT Access Driveway Permit is required before a direct driveway connection to or from a state highway is constructed or modified.”

Limited — Additional ingress to or egress from a public highway for property with a right of direct private access.
“The owner or occupant of property abutting upon a public highway, having a right of direct private access thereto, may provide such other or additional means of ingress from and egress to the highway as will facilitate the efficient use of the property for a particular lawful purpose, subject to reasonable regulation by and permit from the road authority as is necessary to prevent interference with the construction, maintenance and safe use of the highway and its appurtenances and the public use thereof.”
Required — Changes in access to or from a MnDOT right-of-way, including driveway or other access points to a trunk highway, and changes in property use affecting such access.
“An Access / Driveway Permit is required whenever there is a request for change in access to or from a Minnesota Department of Transportation (MnDOT) right-of-way or a change in use of the property.”
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.”
