Do you need a building permit in Clay County, Minnesota?
Yes. Clay County Planning and Zoning requires a building permit for buildings and additions on unincorporated land, including decks, garages, porches, sheds, manufactured homes, prefabricated buildings and trailer homes1. Moorhead and Barnesville issue their own building permits inside city limits1213. Septic permits remain with Clay County Environmental Health in rural and urban areas4. The Minnesota State Building Code is the minimum construction standard throughout the state, including counties and townships, but it is not enforceable by a local government unless that government adopts it by ordinance14. We could not confirm whether unincorporated Clay County has adopted it or what code inspections apply; ask Planning and Zoning before you design15. An eligible owner who will occupy the property or retain it as a rental may personally build without a residential contractor license, but that licensing exemption does not waive county permits82.
Who issues Clay County building permits, and how do you reach them?
Clay County Planning and Zoning handles county building and land-alteration permits at 3510 12th Ave. S. in Moorhead; the office phone is 218-299-501216. The application needs parcel and applicant information, current use, construction and contractor details, applicable shoreland data, and a site sketch9. Submit the township-signed application to the Planning and Zoning Director with the fee, sewage information and any applicable flood certification or state or federal permits917. The ordinance gives the Zoning Administrator 10 working days to approve, deny or refer the application17. The building-permit fee is $25 plus $1 per $1,000 of structure value18. After approval, the county mails a zoning certificate for posting; construction must begin within 6 months and be substantially complete within 1 year unless extended917. Notify the Zoning Administrator immediately after completion for final inspection10.
Does Clay County have zoning, and who zones inside cities?
Clay County zoning applies outside municipal limits, where adopted township regulations may also apply and the most restrictive conflicting provision controls3. Moorhead, Dilworth, Barnesville and Hawley have their own zoning, and the county's zoning page says its incorporated cities, including Comstock, Felton, Georgetown, Glyndon, Hitterdal, Sabin and Ulen, manage their own zoning and permitting1920212223. Septic permits stay with Clay County Environmental Health either way4. County districts include Agricultural General, Agricultural Service Center, Highway Commercial, Limited Highway Commercial and Urban Expansion, with shoreland, flood-hazard and other overlays affecting development24. Agricultural General administrative and standard subdivision lots need at least 1.5 acres and 200 feet of width; cluster lots need 1.5 acres and 100 feet, while agricultural or natural-resource subdivision lots need 1 acre and 100 feet2526. Shoreland districts have separate lot-area and width tables25. For commercial or industrial use, Agricultural Service Center lots need 1 acre and 200 feet of width, while Highway Commercial and Limited Highway Commercial lots need 1 acre and 100 feet27. Maximum lot coverage varies by district and development type, and shoreland rules also limit impervious surface in some situations28; commercial and industrial uses in the Agricultural Service Center, and all uses in the two highway commercial districts, are capped at 30% coverage27. Agricultural General rear and side setbacks are 25 feet and 15 feet; accessory structures have 5-foot rear and 10-foot side setbacks29. Road setbacks run from the centerline: 175 feet for principal arterials, 125 feet for minor arterials and collectors, and generally 90 feet for township roads, with 75 feet in Oakport Township and 65 feet in the Urban Expansion District; the stricter yard or roadway setback applies30.
Who issues septic permits in Clay County, and does that change inside cities?
Clay County Environmental Health issues septic permits and certifications and inspects rural and urban systems throughout Clay County, so a city address still goes to the county for septic permits even though the city issues its own building permits314. Every new septic system needs a design, a county permit and an inspection before backfilling32. Existing septic systems must be certified by the county before an ownership transfer, and the seller is responsible for arranging that inspection33. A building-permit project in the Shoreland Zoning District, or a project that adds a bedroom, also triggers inspection and certification of the on-site system16. Site feasibility deserves early attention because only about 7.1% of Clay County soils are rated without severe limitations for a conventional drain field34. Ask Clay County Environmental Health to review the septic plan before fixing the house location32.
Can you live in an RV or tiny home on your land in Clay County?
Clay County allows no more than 2 recreational vehicles on an individual lot of record in its unincorporated jurisdiction7. Each RV must have current highway-use licensing, remain highway-ready on wheels or an internal jacking system, use only quick-disconnect utilities and have no permanent structural additions; floodplain requirements still apply7. That placement rule does not confirm full-time occupancy, so ask the Planning Office whether the intended living arrangement is permitted3536. Clay County does allow one detached accessory dwelling on a conforming property with an existing single-family home; it must be at least 150 square feet, no more than 75% of the main home's floor area, and meet foundation, location, sewage and district restrictions11. We could not confirm a county rule specific to tiny-home occupancy or a general minimum size for a principal dwelling; ask the Clay County Planning Office before choosing a design36. A new manufactured home installed for occupancy requires a federal installation inspection statewide37.
What are the steps to build a home in Clay County?
Ask the Clay County Planning Office to identify the parcel's district, overlays, setbacks and any township or municipal review32430.
If access will connect to a county highway, obtain the county access permit before right-of-way work38.
Establish a septic design with Clay County Environmental Health and obtain the permit before installation32.
Prepare the prescribed building application, site and sewage information, obtain the township officer's signature, and submit the fee917.
Allow for the Zoning Administrator's 10-working-day decision period, post the mailed zoning certificate, then begin work within 6 months and substantially complete it within 1 year unless an extension is granted917.
Ask which building-code inspections apply, and notify the Zoning Administrator immediately upon completion for the county's final inspection3917.
What should you check before buying land in Clay County?
Before buying rural Clay County land, ask the Planning Office to confirm the district, overlays, township rules, permitted use, lot dimensions and setbacks3242530. Minimum lot area alone does not establish subdivision approval: administrative subdivisions require a pre-application meeting, fee, Planning Department review and site assessment, while major preliminary plats require completeness review, site assessment, a staff report, Planning Commission review and a public hearing4025. Required final subdivision approvals must precede a development permit, and municipal extraterritorial or township approval may also apply41. Only about 7.1% of county soils are rated without severe limitations for a conventional drain field; existing septic systems must be county-certified before ownership transfers3433. Flood Hazard District projects need applicable county approval and certifications42. County-highway right-of-way work needs a county access permit before work starts38.
Watch-outs
A Clay County building-permit application needs a township-officer signature, and the county decision period is 10 working days after submission217. The fee is $25 plus $1 per $1,000 of structure value18.
Existing septic systems must be county-certified before an ownership transfer, and the seller must arrange the inspection43.
Clay County's 2-RV limit does not itself confirm full-time RV occupancy; ask Planning and Zoning about the parcel's district and intended use736.

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.
2020 Minnesota State Building Code effective date: 2020-03-31 (Minnesota Mechanical Fuel Gas Code effective 2020-04-06) · 2024 Minnesota Commercial Energy Code effective date: 2024-01-05 · Adult changing station supplement effective date: 2025-08-15 · Window-cleaning safety feature supplement effective date: 2025-11-07
“(a) 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.”
One more reviewed finding on this topic
Adopted (with conditions) — The Minnesota State Building Code as the statewide construction standard for buildings, including buildings in Clay County.
“The Minnesota State Building Code is the minimum construction standard throughout all of Minnesota including all cities, townships and counties. Although it isn't enforceable by municipalities unless it is adopted by local ordinance, the State Building Code creates a level playing field for the construction industry by establishing the construction standard for all buildings in the state.”
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.”
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)
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.”
