1. Legal Road Access and Title Verification
Before falling in love with a parcel's mountain views, verify legal road access first. In Custer County, proof of ownership and recorded legal access are mandatory before any approach or building permits are issued. The county explicitly states that no permits will be issued without verification of recorded access.
Private Road Ordinances
Under Custer County ordinance, private access roads may serve only one parcel unless the County Board approves otherwise. Furthermore, public road maintenance is generally the responsibility of adjacent landowners unless the county has formally accepted the road.
Title Search & Easement Reviews
Confirm how the parcel is described in public records at the Custer County Register of Deeds. The county planning office does not enforce private subdivision covenants, making buyer title verification essential.
2. Building Permits, Wastewater, and Well Drilling
Assuming land is buildable just because it appears flat or accessible can lead to costly mistakes. Water, septic feasibility, and permit approvals determine buildability and timeline.
County Permits & Septic Approvals
In unincorporated Custer County, building permits are required for structures exceeding 160 square feet (including modular homes and cabins). Dwelling permits require percolation testing and an approved septic system installed by a South Dakota-certified installer.
South Dakota Well Regulations
Unimproved parcels require a licensed South Dakota well driller. Water-right permits must be secured prior to drilling when required, and completed domestic wells require water lab testing for coliform and nitrates.
3. City of Custer vs. Unincorporated County Ownership
City of Custer Municipal Living
Properties within Custer city limits connect to municipal water, sewer, and paved roads maintained by the city under the 2018 International Residential Code (IRC). This setup offers predictable building timelines and hands-off street maintenance.
Rural Custer County Acreage
Rural parcels offer privacy, timber, and proximity to Custer State Park (71,000 acres) and Black Hills National Forest trails. However, rural owners take on full responsibility for private wells, septic care, weed control (noxiously declared pests), fire defensible space, and private snow plowing.
Custer Land & Cabin Buyer Due Diligence Checklist
Before submitting a purchase agreement on land or cabins in Custer County, confirm these ten points:
- Is recorded legal road access verified with the Register of Deeds?
- Who maintains the access road, and what is winter snowplowing cost/availability?
- Is the property inside City of Custer limits or unincorporated Custer County?
- Are there recorded HOA covenants, camping limits, or deed restrictions?
- Is an approved septic system installed, or has a perc test been completed?
- Is a legally adequate water source available (city hookup vs drilled well)?

- What is the parcel subdivision density category (low, medium, high density)?
- Are winter pipe heating and auxiliary power systems operational?
