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.

Rapid City and the Ellsworth corridor

Everything within about twenty five minutes of downtown Rapid City or the Ellsworth main gate, where most of the newer inventory, the shortest commutes and the jurisdiction questions about city versus county service are.

Winter drivingdiffers	Highway 34 is state maintained and connects three directions. County and private roads off it are a different conversation.	Highway 79 is state maintained and is the connection to Hot Springs and Rapid City. Off it, this is open prairie with blowing snow.	Highway 44 is a state priority. Everything off it is county, and open prairie means blowing snow reclaims a cleared road quickly.	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.
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.	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.	No published median exists for the community. Closed sales on the specific street are the only figure worth quoting here.

Housing agediffers	An 1891 townsite with genuinely old buildings, surrounded by ranch and acreage property of every era.	An 1885 to 1939 historic core with an aging housing stock and about a fifth of units vacant.	Mostly late twentieth century through current.	An 1883 mining town, so genuinely old stock alongside newer builds and cabins.

Utilities and rules
Utility patterndiffers	Mostly private well and septic	Mixed, municipal service in town with well and septic outside it	Mixed, municipal service in town with well and septic outside it	Mixed, municipal service in town with well and septic outside it
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.	Town of Buffalo Gap municipal water from a single well, serving about 93 connections. Rural parcels are on private wells.	Not a single system. The Rapid Valley Sanitary District's service area extends past the Rapid Valley boundary and is the likely supplier for much of Green Valley, and there is also a separate Green Valley Sanitary District administered alongside it. Outlying parcels toward Radar Hill and Reservoir Road are on private wells. Confirm per parcel.	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.
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.	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.	District sewer where the district reaches, private septic where it does not. Confirm per parcel.	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.
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.	This is hunting and grassland country rather than a tourism corridor. Demand is seasonal and specific.	Unincorporated county, so no municipal short-term rental ordinance applies. County zoning and any subdivision covenants govern, and state licensing applies once you rent.	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.
Schools

Daily errands
Groceriesdiffers	Nothing in town. Spearfish is eleven miles southeast and Belle Fourche thirteen northwest.	Nothing full service in town. Hot Springs, about 14 miles south, is where errands happen.	The Highway 44 corridor and east Rapid City, a few minutes northwest.	Nothing full service in town. Hill City is the closest small grocery and Rapid City is the real shopping, about 25 minutes northeast.
Healthcarediffers	Monument Health Spearfish Hospital, a 35 bed facility with a 24 hour emergency department, about 18 minutes away.	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.	The Monument Health Rapid Valley Clinic on Elderberry Boulevard for walk-in care, with the hospital in Rapid City.	No clinic in town. Monument Health Custer Hospital has a 24 hour emergency department, and Rapid City has the larger hospital.
Recreationdiffers	Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away.	Buffalo Gap National Grassland, hunting, rock collecting and OHV country, with the Cheyenne River nearby.	Open prairie, the county land east of town, and the whole Black Hills half an hour the other direction.	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.
The trade
Housing and patterndiffers	An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.	A nearly intact turn-of-the-century western streetscape on the National Register, mostly quiet, at the gate to the grassland.	Flat prairie subdivisions east of the city, growing steadily, on county rules.	An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.
What you gaindiffers	The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.	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.	More ground for the money six miles from Rapid City, with Ellsworth fifteen minutes north.	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.
What you give updiffers	A three-way school district split you have to verify per parcel, and no services of any kind in town.	No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.	A school district line that runs through the community, and a water arrangement that changes street to street.	A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.

St. Onge: Highway 34 is state maintained and connects three directions. County and private roads off it are a different conversation.
Buffalo Gap: Highway 79 is state maintained and is the connection to Hot Springs and Rapid City. Off it, this is open prairie with blowing snow.
Green Valley: Highway 44 is a state priority. Everything off it is county, and open prairie means blowing snow reclaims a cleared road quickly.
Keystone: 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.

Housing and lots

Typical pricediffers

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.
Buffalo Gap: 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.
Green Valley: No published median exists for the community. Closed sales on the specific street are the only figure worth quoting here.
Keystone: 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.

Housing agediffers

St. Onge: An 1891 townsite with genuinely old buildings, surrounded by ranch and acreage property of every era.
Buffalo Gap: An 1885 to 1939 historic core with an aging housing stock and about a fifth of units vacant.
Green Valley: Mostly late twentieth century through current.
Keystone: An 1883 mining town, so genuinely old stock alongside newer builds and cabins.

New constructiondiffers

St. Onge: Limited, mostly infill and small projects
Buffalo Gap: None underway
Green Valley: Limited, mostly infill and small projects
Keystone: Limited, mostly infill and small projects

Acreagediffers

St. Onge: Acreage parcels are common here
Buffalo Gap: Acreage parcels are common here
Green Valley: Some acreage, mostly platted town lots
Keystone: Some acreage, mostly platted town lots

Typical lotdiffers

St. Onge: Small townsite lots, with acreage and ranch ground around them.
Buffalo Gap: A handful of historic townsite lots, with grassland and ranch ground around them.
Green Valley: Generous by city standards, with larger parcels toward Radar Hill and Reservoir Road.
Keystone: Small and steep in town, larger on the surrounding hillsides outside the limits.

Covenants and HOA

Covenants are recorded per plat. The title commitment lists what binds the parcel.

St. Onge: Few plats here carry recorded covenants
Buffalo Gap: Few plats here carry recorded covenants
Green Valley: Few plats here carry recorded covenants
Keystone: Few plats here carry recorded covenants

Utilities and rules

Utility patterndiffers

St. Onge: Mostly private well and septic
Buffalo Gap: Mixed, municipal service in town with well and septic outside it
Green Valley: Mixed, municipal service in town with well and septic outside it
Keystone: Mixed, municipal service in town with well and septic outside it

Waterdiffers

St. Onge: 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.
Buffalo Gap: Town of Buffalo Gap municipal water from a single well, serving about 93 connections. Rural parcels are on private wells.
Green Valley: Not a single system. The Rapid Valley Sanitary District's service area extends past the Rapid Valley boundary and is the likely supplier for much of Green Valley, and there is also a separate Green Valley Sanitary District administered alongside it. Outlying parcels toward Radar Hill and Reservoir Road are on private wells. Confirm per parcel.
Keystone: 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.

Sewerdiffers

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.
Buffalo Gap: 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.
Green Valley: District sewer where the district reaches, private septic where it does not. Confirm per parcel.
Keystone: 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.

Short term rentalsdiffers

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.
Buffalo Gap: This is hunting and grassland country rather than a tourism corridor. Demand is seasonal and specific.
Green Valley: Unincorporated county, so no municipal short-term rental ordinance applies. County zoning and any subdivision covenants govern, and state licensing applies once you rent.
Keystone: 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.

Schools

The trade

Housing and patterndiffers

Keystone: An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors.

What you gaindiffers

St. Onge: The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.
Buffalo Gap: 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.
Green Valley: More ground for the money six miles from Rapid City, with Ellsworth fifteen minutes north.
Keystone: 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.

What you give updiffers

St. Onge: A three-way school district split you have to verify per parcel, and no services of any kind in town.
Buffalo Gap: No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.
Green Valley: A school district line that runs through the community, and a water arrangement that changes street to street.
Keystone: A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.

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.
