Unincorporated Daniels County, Montana does not require a local building permit for an ordinary single-family home, but the county has zoning and reviews development applications123.

Do you need a building permit in Daniels County, Montana?
An ordinary single-family home in unincorporated Daniels County does not require a county building permit because the county does not operate a local building-permit program for that work1. Montana's state program still requires a building permit for certain new buildings, alterations, additions and repairs, so the answer changes for a project that is not within a state exemption4. Farm and ranch buildings are exempt from the state building permit where state jurisdiction applies5.
A permit-exempt home is not exempt from land-use or sanitation review: Daniels County has zoning and its Planning Board reviews development applications, while a local drainfield permit remains required even when the land already has state subdivision sanitation approval236. Ask Daniels County Planning to confirm the parcel's zoning before fixing the house location3.
Who handles building and development permits in Daniels County?
Daniels County does not list a local building department for ordinary single-family construction; Daniels County Planning is the practical first stop because the office handles county zoning, subdivision plats and development applications13. Reach Daniels County Planning at 288 Sandhills Road, Dagmar, MT 59219, by phone at 406-483-5431 or by email at [email protected]3.
For a project subject to Montana's state building-permit program, submit construction plans and the Building Permit/Plan Review Application to the state Building Codes Program11. State plan review adds 35% of the building permit fee, and both charges must be paid before issuance12. Required state building permits come before related plumbing, mechanical or electrical permits, and the permit holder must notify the inspector when work is ready413.
Does Daniels County, Montana have zoning?
Yes. Daniels County has an adopted zoning resolution, and the Planning Board reviews subdivision plats and development applications23. Montana law gives county commissioners zoning authority after adoption of a growth policy, but the county resolution—not the general state authority—determines the parcel-level standards142.
The available county information does not establish countywide answers for minimum lot size, setbacks, lot coverage, building height or minimum dwelling size2. Ask Daniels County Planning to identify the zoning designation and applicable standards for the exact parcel before designing a home or accessory structure3. The same parcel-specific check matters for an RV, tiny home, manufactured home or accessory dwelling because no official private-land occupancy rule for those uses was confirmed2.
How do septic permits work in Daniels County?
A drainfield permit from the local health authority is required even when a property already has a Montana Certificate of Subdivision Approval6. The official state directory lists Daniels County Environmental Health/Sanitarian at PO Box 836, Scobey, MT 59263, phone (406) 487-5560 and email [email protected]7. Ask that office about site evaluation, system design, the application and inspections before disturbing the drainfield area7.
Montana DEQ separately reviews sanitation for covered land divisions, condominiums, recreational camping vehicle parks and mobile-home parks; that review covers water supply, sewage disposal, solid waste and storm drainage15. Countywide soil data makes early feasibility work worthwhile because only 7.5% of Daniels County soils rate without severe limitations for a conventional septic drain field10. A more complex or engineered system may be necessary on a particular parcel, but only a site-specific evaluation can answer that question10.
Can you live in an RV or tiny home in Daniels County?
We could not confirm a Daniels County rule that allows or prohibits living in an RV on private land2. We also could not confirm a tiny-home-specific occupancy rule, minimum dwelling size, manufactured-home occupancy rule or accessory-dwelling standard2. Ask Daniels County Planning how the county zoning resolution treats the proposed unit and use on the exact parcel3.
Sanitation is a separate gate: a local drainfield permit is required for an onsite system, and Montana DEQ reviews recreational camping vehicle parks and mobile-home parks regardless of parcel size615. Ask the County Environmental Health/Sanitarian what wastewater approval is needed before occupying any RV or tiny home7. Montana Fish, Wildlife & Parks camping limits apply to public-use sites and do not answer the private-land question in Daniels County16.
Building a home in Daniels County: what are the steps?
- Ask Daniels County Planning to confirm the parcel's zoning designation and whether a development application is needed23.
- Contact the County Environmental Health/Sanitarian for a wastewater site evaluation and the local drainfield-permit process67.
- Confirm whether the structure is exempt from Montana's building permit or is a covered project that needs state plan review, permits and inspections413.
- If the site lies in a designated Special Flood Hazard Area, contact the local floodplain administrator because new development there requires local floodplain review17.
What should you check before buying land in Daniels County?
Start with zoning and wastewater feasibility: Daniels County has zoning, and only 7.5% of county soils rate without severe limitations for a conventional septic drain field210. Ask Planning for the parcel's zoning designation and the County Environmental Health/Sanitarian about a site evaluation before treating a listing as buildable37.
Check water reliability as well: Daniels County averages 14.5 inches of precipitation a year, and severe drought occurs in about 20.6% of years2021. Confirm legal and physical access with the Road Department for a county road; a driveway connecting to a state highway needs an MDT approach permit or right-of-way agreement1819. Determine whether the building site is in a designated Special Flood Hazard Area before closing17. For carrying costs, the county's effective property-tax rate is about 0.9%, with a median annual bill near $1,5332223.
Watch-outs
- No county building permit for an ordinary single-family home does not remove Daniels County zoning or local septic requirements126.
- Private-land RV occupancy, tiny-home occupancy and county dimensional standards could not be confirmed; ask Daniels County Planning about the exact parcel23.
- Only 7.5% of Daniels County soils rate without severe limitations for a conventional septic drain field, so investigate wastewater feasibility before choosing the building site10.
