Rules for Properties in Unincorporated Areas
For properties in unincorporated Custer County, a zoning permit is typically required before any construction, reconstruction, or land development activity. You should contact the Custer County Zoning Administrator to determine specific requirements.
The application process for unincorporated areas generally involves:
- Contacting the Custer County Zoning Administrator to ascertain if a zoning permit is necessary.
- Verifying that the property has recorded access and meets minimum acreage requirements (1 acre minimum for unincorporated Custer County).
- Obtaining and submitting a zoning permit application, potentially with a property survey for setback verification.
- Paying the zoning permit fee.
- For structures that fall under state building code review, you will need to contact the Montana Building and Commercial Measurements Bureau.
- Submitting a state building permit application, which may include plans and specifications for plumbing.
- Undergoing plan review by the state, addressing any comments, and paying associated fees.
- Conducting required inspections at various stages of construction.
Required documents for a permit may include a zoning permit application, property survey, completed state building permit application with plans and specifications, architectural drawings, structural plans, site plans, electrical plans, and plumbing plans.
The cost for a zoning permit is calculated per square foot of total floor area. If work begins before a permit is obtained, the cost increases significantly. Structures must be completed within a specified timeframe after permit issuance, or a new permit will be required.
A permit for a sewage disposal system or variance must be submitted prior to the acceptance of a building permit application.
