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.

Winter drivingdiffers	The commute is I-90, so winter driving here is interstate driving rather than a two lane canyon road.	Black Hills elevation on canyon roads, and a town that empties out for the season. Iron Mountain Road and the scenic routes are not winter commuting roads.	Highway 34 is state maintained and connects three directions. County and private roads off it are a different conversation.	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.
Housing and lots

Black Hills MLS, single family, 24 months through August 2026, as of August 2026. 9 closed sales, small sample.	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.	$340k to $400kMedian sold $367,000. Black Hills MLS, single family, trailing 12 months, as of August 2026. 235 closed sales.
Housing agediffers	Mostly 2000s to present	An 1883 mining town, so genuinely old stock alongside newer builds and cabins.	An 1891 townsite with genuinely old buildings, surrounded by ranch and acreage property of every era.	Heavily new construction since the B-21 announcement

Utilities and rules

Mixed, municipal service in town with well and septic outside it	Mostly private well and septic	City water and sewer inside the limits
Waterdiffers	Black Hawk Water User District, or Diamond D Water in Sun Valley	Town of Keystone municipal water inside the limits, drawn from town wells, with no violations on its current record. Parcels outside the town limits are on private wells.	The Saint Onge Sewer and Water Company serves about 78 connections around the townsite, with a clean compliance record. Parcels outside that system are on private wells. There is no rural water district covering this area.	City of Box Elder municipal
Sewerdiffers	City of Summerset	Confirm with the town before you rely on it. The town operates public works, but I have not been able to verify from the public record whether it runs a collection system or which parcels it reaches. Outside the limits, expect private septic.	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.	City of Box Elder municipal
Short term rentalsdiffers	The thinnest rules on this list, which means a rental plan has to be pinned down for the specific address.	A 2 percent municipal lodging tax applies to transient stays. Whether a separate short term rental ordinance exists is not clear from the public record, so confirm with the town in writing.	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.	A verify first town for rental plans, with one specific misconception the guide clears up.

Daily errands
Groceriesdiffers	Not recorded in this guide. Check what is open near the address.	Nothing full service in town. Hill City is the closest small grocery and Rapid City is the real shopping, about 25 minutes northeast.	Nothing in town. Spearfish is eleven miles southeast and Belle Fourche thirteen northwest.	Lynn's Dakotamart is a full-service grocery store in town.
Healthcarediffers	Hospital-level care is in Rapid City, about 15 minutes south.	No clinic in town. Monument Health Custer Hospital has a 24 hour emergency department, and Rapid City has the larger hospital.	Monument Health Spearfish Hospital, a 35 bed facility with a 24 hour emergency department, about 18 minutes away.	Monument Health Box Elder Clinic provides primary and urgent care in town. Hospital-level care is in Rapid City.
Recreationdiffers	Leisure Lane, Steamboat and Castlewood parks are the everyday recreation. Leisure Lane is the big one, with playgrounds, basketball, picnic shelters, open grass and the community garden.	Mount Rushmore is past the town boundary, the 1880 Train runs from the Winter Street depot, and Custer State Park and the Norbeck Scenic Byway are close.	Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away.	The Liberty Center, the city park and ballfield network, and the South Dakota Air and Space Museum are the in-town recreation. The Badlands are a day trip, not your neighborhood park.

The trade
Housing and patterndiffers	New streets and builder inventory, with Highlands at Norman Ranch adding over 100 first phase homesites across more than 300 acres.	An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.	An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.	A young city building its first downtown at Liberty Plaza on 110 acres, with roughly 800 residential units planned.
What you gaindiffers	Newer houses on city sewer with Hills views at a price central Rapid City does not offer, and Highlands at Norman Ranch is still selling first phase homesites.	Nightly rental demand runs about as high as anywhere in the Black Hills, if the rules and the covenants check out for the specific property.	The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.	The Ellsworth main gate is in town, 9 minutes from most addresses, on city water and sewer, with the region's newest housing pipeline.
What you give updiffers	You are fifteen minutes out from most of Rapid City's services and you drive I-90 to get to them in the winter. The city is also split between Meade 46-1 and Rapid City Area Schools 51-4, so the district follows the address.	A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.	A three-way school district split you have to verify per parcel, and no services of any kind in town.	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.

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.
