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.

In the timber and on the far southern edge, where lots get larger, well and septic get common, and the drive to a full service hospital becomes part of the decision.

Prairie and Badlands

East of the Hills on the open prairie, where lots run larger, water is often a private well, services are thinner and the wind and the drive are the tradeoffs.

Winter roads are a genuine planning factor at this distance, and on acreage you need to know who maintains yours.	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 79 is state maintained and is the connection to Hot Springs and Rapid City.

Housing and lots
Typical pricediffers	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.	Median sold $627,000Black Hills MLS, single family, trailing 12 months, as of August 2026. 7 closed sales, small sample.	About $618,000 average sold, but only 9 sales over 24 monthsAverage sold $618,449. Black Hills MLS, single family, 24 months through August 2026, as of August 2026. 9 closed sales, small sample.	One single family sale shows in the Black Hills MLS over 24 months, at $80,000. One closing is a sample of one rather than a price level, so read it that way.
Housing agediffers	An 1891 townsite with genuinely old buildings, surrounded by ranch and acreage property of every era.	Mixed ages. Older homes near the core, newer construction toward the edges.	An 1883 mining town, so genuinely old stock alongside newer builds and cabins.	An 1885 to 1939 historic core with an aging housing stock and about a fifth of units vacant.
New constructiondiffers	Limited, mostly infill and small projects	Not recorded townwide in this guide. Check current permits with the city or county.	Limited, mostly infill and small projects	None underway

Waterdiffers	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.	Municipal water inside the limits, a private well or a district system outside them.Read off the townwide utility pattern in the guide.

Parcels outside the town limits are on private wells.	Town of Buffalo Gap municipal water from a single well, serving about 93 connections. Rural parcels are on private wells.
Sewerdiffers	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 sewer inside the limits, private septic outside them.Read off the townwide utility pattern in the guide. The service address controls, so confirm the provider before you write an offer.	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.	Not documented in the public record. There is no municipal wastewater project or discharge permit on file that I could find. Confirm with the town finance officer before assuming either town sewer or septic.
Short term rentalsdiffers	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.	Grandfathered permits are non transferable and expire when the property sells, and the rules flip at the city line.	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.	This is hunting and grassland country rather than a tourism corridor.

Fall River Health Services in Hot Springs, a 25 bed critical access hospital with a 24 hour emergency department and a rural health clinic, about 18 minutes away.
Recreationdiffers	Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away.	Custer State Park at the door, including Sylvan Lake, the Needles Highway, the wildlife loop and the September buffalo roundup.	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.	Buffalo Gap National Grassland, hunting, rock collecting and OHV country, with the Cheyenne River nearby.
The trade
Housing and patterndiffers	An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.	A county seat at a park entrance, with a replacement Monument Health hospital and acreage starting just past the city limits.	An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.	A nearly intact turn-of-the-century western streetscape on the National Register, mostly quiet, at the gate to the grassland.
What you gaindiffers	The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.	You are inside the Hills with real acreage, Custer State Park at the door, and a new hospital in a town of about 1,900.	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.	Eighteen minutes from the hospital in Hot Springs, with 600,000 acres of grassland out the door and one MLS closing in two years to price from.
What you give updiffers	A three-way school district split you have to verify per parcel, and no services of any kind in town.	Rapid City is 50 to 60 minutes and Ellsworth over an hour, grandfathered rental permits expire when a property sells, and outside the city limits there are no county building codes.	A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.	No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.

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.

Two towns can look identical in a table and feel nothing alike on a Tuesday night in February. Call or text and tell me which rows above are the ones you cannot live with, and we can work the list down from there.

Address Questions

Considering a home here?

Send the address and we can talk it through. The details that change from one property to the next are jurisdiction, water and sewer, the school the district assigns, covenants, road maintenance and the rest of what never shows up on a listing.
