Do you need a building permit in Houston County, Minnesota?
Unincorporated Houston County requires a zoning permit before buildings, on-site septic systems, substantial improvements, fill, excavation and other listed work in its floodplain districts12. We could not confirm a separate Houston County building-permit requirement for every home outside those districts, so ask Planning & Zoning which approvals apply to the parcel and project17.
The Minnesota State Building Code is the minimum construction standard statewide, although municipal enforcement requires local adoption18. Where the code is administered, the certified building official reviews code requirements and issues the building permit; zoning approval remains separate19. A qualifying owner doing work on personal property may be exempt from residential contractor licensing unless building or improving for resale or speculation, but that exemption does not waive zoning, septic or building permits14.
Houston County exempts tilling, terracing and crop cultivation from the substantial-land-alteration rule; that provision does not establish an agricultural-building exemption or waive other applicable zoning, floodplain, shoreland or septic requirements20.
Who handles building permits and zoning approval in Houston County?
Houston County Planning & Zoning is the first call for a rural building proposal because the office administers planning and zoning in the townships, including floodplain, shoreland, septic-system and feedlot regulation17. The office is at 304 S. Marshall St. in Caledonia; call 507-725-5800 or email zoning@hocomn.gov17. Staff can assist with zoning-permit applications or discuss building proposals, and the Zoning Administrator must accept an application before issuing the zoning permit1721.
The published county fee schedule lists $400 for a dwelling or addition zoning permit22. If construction cannot start with reasonable diligence, the county may extend the permit by one year for $50, allowing up to two years from the original application date23. Work issued a Minnesota building permit requires a final inspection, but we could not confirm Houston County’s local residential inspection administrator; ask Planning & Zoning who serves the parcel2417.
Inside Caledonia, the city handles building and construction permitting, including its own floodplain approval425. County septic administration still applies where no compliant municipal program operates, and Caledonia also requires City Council approval for private sewage systems in its sewer service area626.
Does Houston County, Minnesota have zoning?
Yes. Houston County's zoning ordinance applies outside incorporated municipalities and inside a municipality only if it elects county jurisdiction3. Caledonia and Hokah have their own zoning; county district standards should not be assumed to apply inside those cities2728. County septic administration applies where no compliant city or township program operates6.
Lot size and setbacks depend on the district. Agricultural Protection dwellings generally need at least 1 acre; Residential District dwellings need at least 43,560 square feet with individual septic and wells or 22,000 square feet with central services1516. In both districts, road setbacks can reach 130 feet from a federal or state highway center line and 100 feet from a county-road centerline; side setbacks are 50 feet in Agricultural Protection and 15 feet in the Residential District2930. Shoreland has separate waterbody, bluff and road setbacks, and every applicable setback must be met31.
How do septic permits work in Houston County?
Houston County Environmental Services administers subsurface sewage treatment system (SSTS) permitting where a city or township does not operate a compliant local program; a city or township may run its own program if its ordinance meets state requirements56. Minnesota requires a permit before construction begins on every new or replacement SSTS, followed by an independent construction compliance inspection and final approval through a certificate of compliance78.
The county fee schedule lists $200 for a holding-tank permit, $375 for a Type I system below 2,500 gallons per day, and $1,000 for a homeowner-installed holding or non-holding system22. Planning & Zoning oversees septic-system regulation and is the verified contact for forms and questions17. For a principal structure or septic system wholly or partly in shoreland, Houston County requires a septic certificate of compliance whenever an improvement or use needs a permit or variance32. Only 8.5% of mapped soils are rated without severe limitations for a conventional drain field33.
Can you live in an RV or tiny home in Houston County?
We could not confirm a Houston County rule that generally allows or prohibits full-time RV living on a private rural parcel. Ask Planning & Zoning for a parcel-specific answer because the county administers district, floodplain and shoreland rules in the townships1117. Minnesota's recreational-camping-area license applies to an area accommodating five or more tents or recreational camping vehicles, but that rule does not decide whether one RV may be used as a residence on private land34.
We also could not confirm a county rule written specifically for tiny-home occupancy or a general minimum dwelling size. A tiny home still has to fit the parcel's zoning district, sanitation requirements and any applicable building-code process121335. A new manufactured home is a different regulated category: Minnesota requires an installation inspection before occupancy, and Houston County has district-specific manufactured-home rules3637.
Building a home in Houston County: what are the steps?
Determine whether the parcel is outside an incorporated municipality and ask Houston County Planning & Zoning to identify its mapped district and any floodplain or shoreland controls93817.
Confirm the district's minimum lot size and road, side, rear, shoreland and bluff setbacks before fixing the house site39293031.
Submit the zoning-permit application for acceptance by the Zoning Administrator and budget for the published project fee2122.
Secure the zoning permit before any listed floodplain development2.
Confirm the SSTS authority for the parcel and obtain the construction permit before septic work begins, and arrange the required independent compliance inspection678.
Ask which certified building official has jurisdiction and whether a State Building Code permit is administered for the project19.
Obtain the responsible road authority's permit before adding access to a public highway40.
What should you check before buying land in Houston County?
Start with jurisdiction and the parcel map: county zoning applies outside incorporated municipalities, while municipal zoning may differ941. Ask Planning & Zoning for the parcel's district, floodplain and shoreland status, permitted use, minimum lot area and setbacks before making the purchase unconditional173931. Then investigate septic feasibility, because only 8.5% of mapped county soils are rated without severe limits for a conventional drain field33.
Houston County's terrain also affects siting and cost: 52.6% of the land is at a slope of 15% or less, while 41.7% is wooded4243. Verify legal and physical road access, since a new connection to a public highway is subject to a permit from the road authority40. We could not confirm the private-well permit process, so ask Planning & Zoning which office should review the water source17. The median property-tax bill is about $2,633 per year and the effective rate is about 1.2%4445.
Watch-outs
Houston County’s floodplain zoning permit is separate from the building-code permit process; ask Planning & Zoning which approvals apply to the parcel21917.
Only 8.5% of mapped Houston County soils are rated without severe limitations for a conventional septic drain field, so investigate septic feasibility before choosing the house site33.
Long-term RV occupancy, tiny-home occupancy, a general minimum dwelling size and the private-well permit path remain unconfirmed; ask Planning & Zoning for parcel-specific direction1117.
Minimum lot size and setbacks vary by zoning district, road type, utilities and shoreland status; confirm all overlays before choosing a building site39293031.

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.

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”
One more reviewed finding on this topic
Required — Work for which a Minnesota building permit is issued.
“A final inspection shall be made for all work for which a permit is issued.”
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.”
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.”

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
New construction and replacement subsurface sewage treatment systems (SSTS) in Minnesota, including Houston County.
Minnesota Rules require permits for all new construction and replacement SSTS.
A local unit of government may require permits for all or certain types of SSTS repairs; repair permitting is therefore not uniformly required by this provision.
The local unit of government must review and approve or deny the permit application before issuing a construction permit.
Construction must not be initiated until a construction permit is granted.
Final approval must be evidenced by a certificate of compliance.
“Permits must be required for all new construction and replacement. A local unit of government is authorized to require permits for all or certain types of SSTS repairs.”
One more reviewed finding on this topic
Required — Construction of most Minnesota SSTS, with construction permits issued by the applicable county, city, or township; large SSTS require MPCA permitting.
“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”
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).”
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.”
