Do you need a building permit in Wheatland County, Montana?
A single-family residence in unincorporated Wheatland County generally does not need a state building permit unless a local government requires one by ordinance or resolution1. Farm and ranch buildings and private owner-use garages or storage buildings are also exempt from the state permit requirement15. Montana nevertheless enforces a uniform statewide building code for residential and commercial buildings; a permit exemption is not the same as having no code2.
Montana requires a building permit before certain non-exempt new construction, alterations, additions and repairs begin16. Projects subject to the state program receive inspections required by Montana law, and the permit holder must notify the inspector when work is ready73. Separate plumbing, mechanical or electrical permits may still be required, so describe the complete project to the Montana Building Codes Program before work starts1718.
Who handles Wheatland County building permits and inspections?
Wheatland County's department listing does not identify a county building department, and the county appears not to require a residential building permit in unincorporated areas19. For a non-exempt project under state jurisdiction, contact the Montana Building Codes Program at (406) 841-2056 or buildingcodes@mt.gov18. The state office specifically invites applicants to ask when they are unsure whether a building needs a permit18.
For a covered project, submit the application and construction plans to the state program1820. The reviewer calculates valuation and fees, checks the plans, communicates deficiencies and issues the permit after compliance and full payment; review can take from a few hours to several weeks21. The separate plan-review fee is 35 percent of the building-permit fee22.
Does Wheatland County have zoning?
Wheatland County has a Planning Board that meets quarterly, but we could not confirm whether a countywide zoning ordinance governs unincorporated parcels58. Montana law allows counties to adopt zoning, but that authority alone does not show that Wheatland County has done so23. Harlowton does have local zoning: its Planning and Zoning Commission reviews zoning amendments, site plans and plat applications6.
For an unincorporated parcel, ask the Wheatland County Planning Board about zoning, setbacks, minimum lot and dwelling size, building height and lot coverage58. For land inside Harlowton, ask the city about its Land Development Code and building-code requirements6. In either location, subdivision sanitation review and septic approval are separate from zoning244.
How do septic permits work in Wheatland County?
Central Montana Health District administers Wheatland County's septic program, including permits and inspections for DEQ-regulated systems4925. A new system costs $475 with a certified installer or $650 with an uncertified installer, including the site visit; other published fees vary by system and installer26. A state Certificate of Subdivision Approval does not replace the local drainfield permit27.
Only about 23.9% of Wheatland County soils are rated without severe limitations for a conventional septic drain field, so do not assume a standard system will work before a site evaluation28. For subdivisions with lots greater than 20 acres, the district review asks for water and sanitation information and requires at least 4 feet of vertical separation below a new onsite system; groundwater within 7 feet triggers additional evidence29. Contact the district at 406-566-2277 before choosing a house site30.
Can you live in an RV or tiny home on your land in Wheatland County?
We could not confirm a countywide rule for long-term RV living, temporary camping on private land or tiny-home occupancy in Wheatland County5. The Montana rule limiting stays at Fish, Wildlife & Parks public-use sites applies only to those public sites and does not answer whether someone may occupy an RV on private property31.
Ask the Wheatland County Planning Board for a written, parcel-specific answer before moving an RV or tiny home onto unincorporated land8. Inside Harlowton, the city's zoning and land-development rules apply6. A development with permanent recreational-vehicle spaces may also trigger subdivision sanitation review regardless of parcel size, and a tiny home may need a septic permit even when no state building permit is required24127.
Building a home in Wheatland County: the steps, in order
Email the Wheatland County Planning Board with the parcel number and ask whether zoning, setbacks, floodplain review or subdivision conditions apply; inside Harlowton, confirm city zoning too586.
If land is being divided, determine whether state or district sanitation review applies; DEQ reviews divisions creating parcels under 20 acres, while Central Montana Health District has a review for lots greater than 20 acres2429.
Confirm wastewater feasibility with Central Montana Health District and obtain the septic permit before installation49.
Describe the building and trades to the Montana Building Codes Program; a single-family home may be permit-exempt, while covered projects require plan review and inspection1718.
If a state building permit is required, submit plans and the application, resolve review comments and pay all fees before construction2022.
Check state-highway access and DNRC water-right requirements before driveway or well work3212.
What should you check before buying land in Wheatland County?
Start with septic feasibility: only about 23.9% of county soils avoid severe limitations for a conventional drain field, making an early site evaluation valuable28. Water planning matters too because Wheatland County averages about 16.2 inches of precipitation annually and has experienced severe drought in about 12.1% of years3334. A qualifying groundwater development may use Montana's permit exception, but specified exceptions require a Notice of Intent beginning in 202612.
Confirm legal access and whether a driveway will intersect a state highway, which triggers MDT approach review32. Ask the Planning Board about zoning and mapped flood risk because Wheatland County's parcel-level zoning and floodplain requirements were not confirmed58. If the parcel comes from a subdivision, obtain its sanitation approval and recorded plat; the county charges a $25 base filing fee plus per-lot charges for subdivision plats35.
Watch-outs
Do not read the single-family building-permit exemption as an exemption from the statewide code or from plumbing, electrical, mechanical, septic, zoning or floodplain requirements121727.
Countywide RV occupancy, tiny-home occupancy, setbacks and minimum dwelling size remain unconfirmed; ask the Wheatland County Planning Board for a parcel-specific answer58.
Only about 23.9% of Wheatland County soils avoid severe limits for a conventional septic drain field, so verify the building site before buying28.

Well permitLimited
New groundwater developments in Montana using 35 gallons per minute or less and no more than 10 acre-feet per year.
All water uses starting after June 30, 1973, require a water right either through a water-use permit or an exception to the permitting process.
The development may qualify for the exception; qualification is not automatic.
Completed groundwater uses that meet the permit exception receive a Groundwater Certificate rather than a water permit.
A permitted water right is required for a combined appropriation from the same source by two or more wells or developed springs exceeding 10 acre-feet, regardless of flow rate.
All lots in a multi-phase subdivision must share a combined water-use limit of 10 acre-feet per year to qualify for a permit exception.
Beginning January 1, 2026, a water user intending to develop water use through a permit exception must file a Notice of Intent with DNRC before using water from an exempt well.
DNRC reviews a correct and complete Notice of Intent within 10 business days; if eligible, it authorizes the Notice of Intent and gives the user five years to complete the project, put the water to use, and file a Notice of Completion.
If the proposed use is not eligible, the Notice of Intent is denied and the user is directed to the water-right permit process.
The Notice of Intent filing fee is $400.
An authorized Notice of Intent expires after five years, with an opportunity for one five-year extension.
maximum flow rate: <= 35 gpm · maximum annual volume: <= 10 acre-feet per year · Notice of Intent fee: 400 USD (Beginning January 1, 2026) · Notice of Intent review period: 10 business days (For a correct and complete Notice of Intent) · authorized Notice of Intent term: 5 years (One five-year extension opportunity is available)
