How tall can a fence be in Rapid City?

Rapid City's zoning code limits fences in residential, general agricultural, park forest and public districts to 4 feet in any front yard and 6 feet in other yards. On corner and double-frontage lots, a fence can be up to 6 feet in the second front yard if it sits at least 10 feet back from the property line. Commercial and industrial districts allow up to 8 feet. Height is measured from the top of the fence to the ground beneath it. Fences, walls and plantings also can't block the sight triangle at an intersection.

When does a Rapid City fence need a permit?

The code requires a building permit for all fences over 6 feet. Fences at or under 6 feet generally don't need one, though the height limits above still apply. A fence in a designated easement needs written approval from the City Engineer, and a fence in the public right-of-way needs Common Council approval. The city's Building Services Division handles building permits and contractor licenses.

What materials are restricted in town?

Barbed wire is banned in residential, park forest, mobile home, neighborhood commercial, public and floodway districts. Electric fences are banned citywide except in general agricultural and airport districts, and any legal electric fence needs a controller listed by a recognized testing laboratory.

What does Summerset require?

Summerset requires a fence permit for all fence installation, with a $50 fee, and all contractors must be licensed with the city before work starts. Residential fences can't exceed 6 feet. Fences must sit entirely on the owner's property unless the neighbor agrees in writing, stay out of major drainage easements and rights-of-way, and stay at least 2 feet from sidewalks. Wood must be decay resistant or treated. Posts are spaced no more than 8 feet apart; wood posts go at least 3 feet deep, or 2 feet set in a cubic foot of concrete. In Sun Valley, fences must be at least 12½ feet from the Williston Basin Pipeline easement.

What about unincorporated Pennington County?

For property outside city limits, PermitMint's summary of county rules says fences 7 feet or less are exempt from a building permit under the 2021 International Residential Code, while taller fences need one through Pennington County Planning and Zoning. Zoning can still limit height and setbacks, and subdivision covenants or an HOA may require their own approval. Call the county planning office to confirm before you build.

Who has to call 811?

The South Dakota Public Utilities Commission says state law requires notifying South Dakota 811 at least two working days before any excavation, which includes digging post holes. The service is free, homeowners and excavators can request a locate online, and the digger is responsible for avoiding the marked areas.

How should I check out a fence contractor?

The City of Rapid City advises residents to make sure a contractor is licensed in Rapid City, and warns that contractors who claim a state license usually have only a state excise tax license. Ask for references, a written quote and a clear answer about who pulls any permit. Questions go to the city's Building Services Division.

How do Rapid City's weather and soil affect a fence?

Rapid City averages about 17 inches of precipitation and 48 inches of snow a year. Chinook winds can push temperatures above 50°F around 20 times between December and February, and cold fronts bring gusty northwest winds in the fall. Western South Dakota frost commonly reaches about 42 inches. Parts of the city also have clay soils that swell and shrink with moisture, an issue Rapid City officials have dealt with on home foundations. All of that argues for posts set deep, sized for the wind, and drained at the base.

Is a wood fence a wildfire risk?

It can be when it's attached to the house. The University of California's fire network notes that attached fences connect easily ignited material directly to an exterior wall, and recommends replacing the last 5 feet with a noncombustible section such as a metal gate. That's worth considering on foothill lots around Rapid City and Hill City.
