Permit takeaway

Billings says fences three to six feet high require a Planning Department permit, while fences over seven feet require a building permit and must be designed for a 105 mph wind load.

Zoning and placement

Fence location and setbacks are reviewed by Planning, and taller residential fences must be located at the required building setback for the district.

Building and trade review

Retaining walls that are four feet or more in height or support surcharge or slope require a building permit and Montana-licensed engineer design.

Call before applying when

Call before applying if the fence is over three feet, over six feet, near a setback, or if a retaining wall is near four feet high or supports a driveway, slope, building, or other surcharge.
