Building permits, zoning and septic rules in Lake of the Woods County, Minnesota
65Index Score / 100 #27 of 87 in Minnesota
Lake of the Woods County, Minnesota requires a building permit, applied for through the county's Land Use Permit Application with fees, at the Land & Water Planning Office12. That same office enforces county zoning and runs septic (SSTS) permitting for the county34. We could not confirm who performs building inspections, so ask the office before you hire trades5.

Do you need a building permit in Lake of the Woods County, Minnesota?
Yes. Lake of the Woods County requires a building permit, and the county's application route is a complete Land Use Permit Application with the appropriate fee, delivered to Land & Water Planning in person or by mail12. The state permit rule covers construction, enlargement, alteration, repair, movement and demolition, with listed exemptions such as one-story detached sheds and similar accessory structures of 200 square feet or less, fences, sidewalks and driveways14. Minnesota's State Building Code is the minimum construction standard statewide, but it does not apply to agricultural buildings except for the statutory exceptions, and local enforcement depends on local adoption515. We could not confirm a county building official or inspection schedule, so ask Land & Water Planning whether your project needs any inspection beyond the Land Use Permit before ordering materials8.
Who handles building and land-use permits in Lake of the Woods County?
Lake of the Woods County Land & Water Planning is the first stop for a home, cabin or other land-development proposal because the office administers zoning and the county Land Use Permit process316. The office is at 206 8th Ave SE, Suite #290, Baudette, MN 56623, and its phone number is (218) 634-19458. Applications must be complete, include the appropriate fee and be submitted in person or by mail16. We could not confirm a general building-inspection contact, so ask Land & Water Planning to identify any separate building official or inspection authority for the parcel8. For a county-road entrance, contact the separate Lake of the Woods County Highway Department at 306 8th Ave SE, Baudette, MN 56623, by calling 218-634-176712.
Does Lake of the Woods County have zoning?
Yes. Lake of the Woods County Land & Water Planning develops, implements and enforces the county zoning ordinance, maintains official records and maps, performs site analysis, and processes zone changes, conditional use permits and variances38. That makes the zoning district and parcel map essential before choosing a house location or buying land3. The available county material does not confirm one countywide numeric setback, minimum lot size, minimum dwelling size, building-height limit or lot-coverage limit. Ask Land & Water Planning for the rules tied to the parcel's zoning district, shoreland status and proposed use8. The county publishes its zoning ordinance and a separate floodplain ordinance online17. A residential planned unit development needs a Conditional Use Permit18. A short-term vacation rental in the Rural Residential (R2) district needs an Interim Use Permit under Section 1106 of the zoning ordinance19. Minnesota law also allows qualifying municipalities to adopt subdivision regulations, so a proposed parcel split needs a specific answer from the authority that governs the property20.
How do septic permits work in Lake of the Woods County?
Lake of the Woods County Land & Water Planning administers the county septic ordinance, reviews sewer designs and grants permits74. Minnesota local governments issue construction permits for most subsurface sewage treatment systems, while systems designed for flows greater than 10,000 gallons per day require an MPCA permit2122. Site feasibility deserves early attention because 0% of mapped county soils are rated free of severe limitations for a conventional drain field13. That soil rating does not make septic impossible, but it supports budgeting for a professional site evaluation and potentially a nonconventional design13. Contact the county SSTS office at (218) 634-1945 before finalizing a house site or purchase contract23. Off-grid sanitation is not a free pass: Minnesota's rules for primitive dwellings require owner-managed toilet waste to follow local ordinances and impose disposal safeguards where no local ordinance exists24.
Can you live in an RV or tiny home in Lake of the Woods County?
Lake of the Woods County has county zoning, but the available county rules do not confirm a countywide allowance for living in an RV on private land or a specific tiny-home occupancy standard6. The only RV rule we found is district-specific: using a recreational vehicle in the Residential Development (R1) district on Rainy River took a Conditional Use Permit under Section 401.B of the zoning ordinance, and other districts may differ25. Ask Land & Water Planning how the parcel's district treats a recreational vehicle, a tiny home on wheels, or a small permanent dwelling before buying or moving one onsite8. Minnesota's campground statute is not an answer for a single household: it addresses areas accommodating 5 or more tents or recreational camping vehicles and requires state licensing subject to listed exceptions26. A new manufactured home installed for occupancy in Minnesota must be inspected under the federal installation standards program27. Any occupied setup also needs a lawful wastewater plan because Lake of the Woods County administers its septic ordinance and reviews sewer designs4.
How do you build a home in Lake of the Woods County?
Ask Lake of the Woods County Land & Water Planning to confirm the parcel's zoning district, applicable setbacks, floodplain status and the permits required for the proposed home38.
Arrange septic site and design work early because 0% of mapped county soils are rated free of severe limitations for a conventional drain field13.
Submit the complete Land Use Permit Application with the appropriate fee in person or by mail16.
Apply through Land & Water Planning for the county-administered septic approval and design review4.
Ask whether a local building official will inspect the project, since the State Building Code is the statewide construction standard but county enforcement was not established51.
Obtain access approval from the appropriate road authority; the county Highway Department publishes an approach-permit application for roads under county jurisdiction1112.
If the project is in a floodplain, the county's Floodplain Ordinance applies, and one case needed a Conditional Use Permit under Section 6.3 for an alternative elevation method28. Also obtain the community floodplain permit before building a house, placing fill, or installing a culvert or bridge29.
What should you check before buying land in Lake of the Woods County?
Start with septic feasibility: 0% of mapped Lake of the Woods County soils are rated free of severe limitations for a conventional drain field13. The county is very sparsely populated at 2.9 people per square mile, and the nearest city of 100,000 or more people is about 165 miles from the county center, so contractor travel and material logistics deserve attention3031. The terrain is mostly gentle, with 99.1% of land at a slope of 15% or less, while 49.4% is wooded3233. Check mapped floodplain status because houses, fill, culverts and bridges in regulated floodplain areas require a community floodplain permit29. Confirm which road authority controls the frontage before assuming a driveway location, because access to a public highway is subject to regulation and a permit from that authority11. Typical property tax is about 0.7%, with a median annual bill of $1,5203435.
Watch-outs
A Lake of the Woods County Land Use Permit does not settle who inspects the work; ask Land & Water Planning who enforces the State Building Code for the parcel58.
Countywide RV occupancy, tiny-home occupancy, minimum dwelling size and numeric setbacks could not be confirmed; obtain parcel-specific answers from Land & Water Planning before purchase8.
Mapped soils show 0% of the county free of severe limitations for a conventional septic drain field, so make septic feasibility a contract contingency rather than a later design detail13.
A driveway onto a public highway needs approval from the road authority, which may be the county, the state or another authority depending on the road11.
Short-term vacation rentals in the Rural Residential (R2) district need an Interim Use Permit, so confirm the parcel's district before buying for rental income19.

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)
Construction, reconstruction, alteration, repair, and use of buildings and other structures of the type governed by the Minnesota State Building Code throughout Minnesota.
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.
Municipal enforcement generally requires adoption by local ordinance, subject to statutory requirements for certain municipalities and statutory enforcement responsibilities where no adoption ordinance is in effect.
The 2024 Minnesota Commercial Energy Code is effective January 5, 2024.
Requirements for adult changing stations are effective August 15, 2025, and requirements for window-cleaning safety features are effective November 7, 2025, according to the Department of Labor and Industry update page.

Adopted — Minnesota State Building Code applicable to covered construction in Lake of the Woods County.
“The State Building Code is the standard that applies statewide for the construction, reconstruction, alteration, repair, and use of buildings”
InspectionsRequired
Construction or work for which a Minnesota State Building Code permit is required.
The work must remain accessible and exposed until approved.
The permit applicant must cause the work to remain accessible and exposed for inspection.
The building official identifies required inspections; the permit holder must maintain the inspection record card until final approval.
Work may not proceed beyond each successive inspection point without building-official approval; noncomplying portions must be corrected and may not be covered or concealed until authorized.
“Construction or work for which a permit is required is subject to inspection by the building official”
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.”
Manufactured homesLimited
New manufactured homes installed for occupancy statewide in Minnesota
Inspection is required under Federal Installation Standards Programs, CFR 3285 and 3286.
Manufactured-home alterations require documentation submitted for review to the Department of Labor and Industry or the local authority having jurisdiction before work begins.
Local building officials and local code enforcement may apply depending on the municipality.
“All new manufactured homes installed in Minnesota for occupancy are required to be inspected according to the Federal Installation Standards Programs, Code of Federal Regulations (CFR) 3285 and 3286.”
Accessory dwellingsLimited
Temporary family health care dwellings used as a narrow accessory residential dwelling category statewide, where the municipality has not opted out of Minnesota Statutes § 462.3593.
The dwelling must be primarily assembled away from its installation site, be no more than 300 gross square feet, lack a permanent foundation, meet state-recognized accessibility standards, provide water and electric utilities, use compatible exterior materials, have at least R-15 insulation, be transportable by the specified truck types, comply with Minnesota Rules chapter 1360 or 1361 with the required seal and data plate or ANSI Code 119.2, and have a backflow check valve.
A caregiver or relative must apply for a municipal temporary dwelling permit with the required signatures and documentation, including provider-network proof, medical certification, septic-service documentation, adjacent-owner notice affidavit, and a site map.
The dwelling must be on property where the caregiver or relative resides, comply with setbacks and applicable floor-area-ratio limits, and permit safe and timely access for septic services and emergency vehicles.
Occupancy is limited to one identified mentally or physically impaired person, and only one temporary family health care dwelling is allowed per lot.
The dwelling must comply with applicable state law, local ordinances, and charter provisions unless otherwise provided.
The initial permit lasts six months and may be renewed once for an additional six months.
The municipality may inspect, revoke the permit for violations, and require removal within 60 days after revocation.
Unless otherwise provided by ordinance, the municipality may charge up to $100 for the initial permit and up to $50 for renewal.
The municipality may opt out of the statutory requirements by ordinance.
maximum dwelling area: <= 300 gross square feet · initial permit term: 6 months (renewable once for an additional six months) · maximum initial permit fee: <= 100 USD (unless otherwise provided by ordinance) · maximum renewal permit fee: <= 50 USD (unless otherwise provided by ordinance) · maximum occupants: 1 person (occupant must be a mentally or physically impaired person) · maximum dwellings per lot: 1 dwelling
“A temporary family health care dwelling that meets the requirements of this section cannot be prohibited by a local ordinance that regulates accessory uses or recreational vehicle parking or storage.”
One more reviewed finding on this topic
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.”
Septic permitRequired
Construction of most Minnesota SSTS, with construction permits issued by the applicable county, city, or township; large SSTS require MPCA permitting.
Local authority and local ordinance requirements vary.
Large SSTS designed for a flow greater than 10,000 gallons per day must be permitted by MPCA.
Local government units may adopt stricter requirements.
large SSTS design flow: > 10000 gallons per day (Systems at or below this threshold are generally reviewed and permitted by counties, cities, or townships.)
“Counties, cities, and townships review designs and issue construction permits for most SSTS in Minnesota, but large sub-surface sewage treatment systems (LSTS) — designed to manage a flow of greater than 10,000 gallons a day — must be permitted by the MPCA”
Septic inspectionLimited
Compliance inspection of an existing septic system before sale or transfer of property in Minnesota.
Minnesota state regulations do not require a compliance inspection before property sale or transfer.
Many county, city, or township ordinances require such inspections, especially in shoreland areas.
A statutory inspection is required before a local unit of government issues a building permit or variance for an added bedroom on property served by a system, unless the local government lacks an ordinance requiring a building permit for that bedroom addition.
For an application made from November 1 through April 30, the local unit may temporarily waive the inspection if inspection occurs by the following June 1 and the applicant submits the certificate or notice within 15 days.
A certificate of compliance for an existing system is valid for three years unless the local unit finds an imminent threat to public health or safety.
existing-system certificate validity: 3 years (unless the local unit of government finds evidence of an imminent threat to public health or safety)
“Minnesota state regulations don’t require a compliance inspection before a property is sold or transferred, but many county, city, or township ordinances do, especially in shoreland areas.”
One more reviewed finding on this topic
Required — Inspection of all new construction or replacement of a subsurface sewage treatment system in Minnesota.
“An inspection shall be required for all new construction or replacement of a system to determine compliance with applicable requirements. The manner and timing of inspection may be determined by the applicable local ordinance.”
Off-grid sanitationLimited
Primitive dwellings using toilet-waste treatment devices in low dwelling-density areas, and privies governed by Minnesota SSTS rules.
Septage disposal by the owner must follow local ordinances.
If no local ordinance exists, septage must not be discharged to surface waters, drainageways, steeply sloping areas, or wet areas in a manner or volume harmful to the environment or public health or that creates a nuisance.
Material must be buried or covered with soil.
If site conditions do not meet the rule, solids disposal must be performed under the applicable rule by a licensed maintenance business.
Privy solids must be removed when the privy is filled to one-half capacity.
Abandoned pits must have sewage solids and contaminated soil removed and be filled with clean earth and slightly mounded.
“For primitive dwellings using toilet waste treatment devices in low dwelling density areas, septage disposal from these devices by the owner must be in accordance with local ordinances. If no ordinance exists, the septage must not be discharged to surface waters, drainageways, steeply sloping areas, or wet areas in a manner or volume that is harmful to the environment or public health or that creates a nuisance. The material must be buried or covered with soil.”
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)

“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.”
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.”

Permit feesVariable (with conditions)
Building permit fees under the Minnesota State Building Code, as administered by local building departments.
Fees are established by the local building department and are not supplied as one statewide fee schedule.
Fees must be commensurate with services provided and reasonable, fair, and proportionate to actual service costs.
Fees may include building permit, plan review, state surcharge, electrical, plumbing, heating/mechanical, septic, and sewer and water fees.
Permit fees are generally based on construction valuation and/or a fee for service.
The applicant must provide an estimated construction valuation, subject to verification by the building official.
Municipal fee schedules may include special investigation, penalty, reinspection, plan-review, fixed, and refund-policy fees.
“It is for this reason that the building code does not specifically identify or provide for a fee schedule to be used by a jurisdiction. Each municipality is to evaluate local costs associated with the enforcement of the code.”

Variable (with conditions) — Minnesota State Building Code permit fees administered by adopting local municipalities.
“Permit fees are to be determined and established by the local municipality. Permit fees must be established so that they cover all costs associated with administration and enforcement the State Building Code - to run a functioning building department. Permit fees can be developed on a “fixed fee” basis and on a construction “value” type of sliding fee schedule, or a combination of both.”
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.”
