Compare Black Hills Communities

25 towns and unincorporated communities. Pick two to four and the full table appears underneath. Commutes are driving times to the Ellsworth main gate and downtown Rapid City. Median sold prices, where we have them, come from the MLS over the trailing twelve months with the source, window and sale count printed under each figure. Typical price bands are practical search ranges, not medians, and are labelled separately.

Price filters only consider communities with a published trailing twelve month median, so towns without one do not appear in a price filter.

Winter drivingdiffers

Box Elder
I-90 is state maintained and the city clears the newer plats. Box Elder publishes no plow priority map, so ask a neighbor how the street clears after a real storm.
Edgemont

Spearfish
Chinook winds off the hills are a genuine feature of winter in this corridor.
St. Onge
Highway 34 is state maintained and connects three directions. County and private roads off it are a different conversation.

Housing and lots

Typical pricediffers

Box Elder
$340k to $400kMedian sold $367,000. Black Hills MLS, single family, trailing 12 months, as of August 2026. 235 closed sales.
Edgemont
About $155,000 average sold, 13 sales over 24 monthsAverage sold $155,285. Black Hills MLS, single family, 24 months through August 2026, as of August 2026. 13 closed sales.
Spearfish
$400k to $600kMedian sold $475,000. Mount Rushmore Area MLS, all residential, trailing 12 months, as of August 2026. 199 closed sales.
St. Onge
No figure published. St. Onge is Mount Rushmore Area MLS territory and the current feed covers only the Black Hills MLS, so a zero here would be a gap in the data rather than a fact about the market.

Utilities and rules

Utility patterndiffers

Box Elder
City water and sewer inside the limits
Edgemont
City water and sewer inside the limits
Spearfish
City water and sewer are typical inside city-served areas. Acreage outside the city can use wells, septic systems or other service arrangements, so utilities should be confirmed by address.

Mostly private well and septic

Waterdiffers

Box Elder
City of Box Elder municipal
Edgemont
City of Edgemont municipal water. Rural parcels are on private wells.
Spearfish
City water inside the Spearfish limits. Acreage outside the limits runs on a private well or a rural water district.Read off the townwide utility pattern in the guide. The service address controls, so confirm the provider before you write an offer.
St. Onge

Spearfish
City sewer inside the Spearfish limits, private septic on acreage outside them.Read off the townwide utility pattern in the guide. The service address controls, so confirm the provider before you write an offer.
St. Onge
The water company's name implies sewer service, but I have not been able to verify from the public record which parcels it reaches. Assume private septic outside the townsite and confirm the rest before closing.

Short term rentalsdiffers

Box Elder
A verify first town for rental plans, with one specific misconception the guide clears up.
Edgemont
Edgemont is not a tourism town. Short-term rental demand here is work crews, hunting season and Rally traffic passing through, not visitors staying to see something.
Spearfish
The city studied rules in 2023 and 2024 and maintains an official short term rental page. Verify the current ordinance first.
St. Onge
Unincorporated Lawrence County, so no municipal ordinance applies. Note that unincorporated Lawrence County declined to require a vacation home rental permit, so there is no county permit to obtain either.

The trade

Housing and patterndiffers

Box Elder
A young city building its first downtown at Liberty Plaza on 110 acres, with roughly 800 residential units planned.
Edgemont
A working BNSF crew-change town founded in 1890, at the far southern edge of the Hills below the Elk Mountains.
Spearfish
A university town with a walkable middle, growing fast enough that new construction has moved to the edges.

An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.

What you gaindiffers

Box Elder
The Ellsworth main gate is in town, 9 minutes from most addresses, on city water and sewer, with the region's newest housing pipeline.
Edgemont
More town per dollar than anywhere else in the region, with its own school district and city utilities.
Spearfish
A downtown you can walk across, Black Hills State and Spearfish Canyon out the back door, on city water and sewer.
St. Onge
The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.

What you give updiffers

Box Elder
Comparable sales run thin inside brand new subdivisions and builder incentives move the effective price without moving the list price. I-90 fills at shift change, and the flight line is close enough that you hear it.
Edgemont
A hundred miles from Rapid City, 35 from a hospital, with two unresolved questions hanging over the local economy.
Spearfish
The highest median sold price of the region's higher volume markets at $475,000 across 199 sales, and Rapid City is 53 minutes on the interstate with the Ellsworth gate 68.
St. Onge
A three-way school district split you have to verify per parcel, and no services of any kind in town.
Where this comes from

Commute figures are driving times off peak, from the community guide each card links to. Median sold prices come from the MLS, and each figure carries its own source, window and closing count, because Sturgis, Spearfish and the northern hills report through a different MLS than Rapid City. Under five closings there is no median, and the price row says so. Five to nine closings carries a small sample note. School districts follow the official boundary for the address, and the district office is the only place to confirm an assignment. Short term rental lines are summaries. Read the guide and the current ordinance before you count on rental income.

The filters use these definitions: under $400k is the MLS sold figure for the town, a median where one is published and otherwise the average sold, comes in under $400,000; close to ellsworth is 25 minutes or less to the Ellsworth main gate; close to rapid city is 20 minutes or less to downtown Rapid City; short commute is 15 minutes or less to either downtown Rapid City or the Ellsworth gate; new construction available is the guide establishes active or limited new construction; acreage available is acreage is common or present in the guide; city water and sewer is city water and sewer across the community; smaller market is fewer than 100 closed single family sales in the trailing twelve months; more rural is acreage is common, or water and sewer are not municipal throughout; established housing is the guide classifies the housing stock as established, meaning largely pre 2000; newer housing is the guide classifies a meaningful share of the housing stock as 2000s or later.

Every row here is a townwide summary and a single parcel can read differently. Buyer due diligence should include verifying water and sewer service, school assignment, recorded covenants and HOA obligations, rental rules, legal access, insurance availability and which jurisdiction inspects and permits the work, for the exact address. Confirm with the city or county, the utility or district, the school district office, the title company and your insurer as applicable.
