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.

Utilities and rules
Utility patterndiffers	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	Mostly private well and septic
Waterdiffers	Municipal water inside the limits, a private well or a district system outside them.Read off the townwide utility pattern in the guide. The service address controls, so confirm the provider before you write an offer.	Town of Buffalo Gap municipal water from a single well, serving about 93 connections. Rural parcels are on private wells.	Town of Hermosa water inside the limits. The Hermosa Water Users Association is a separate system, and rural parcels are commonly on private wells. Which one serves a given address has to be checked address by address.	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.
Sewerdiffers	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.	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.	Town sewer with lagoon treatment inside the limits, currently being expanded. Rural parcels are on 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.
Short term rentalsdiffers	Grandfathered permits are non transferable and expire when the property sells, and the rules flip at the city line.	This is hunting and grassland country rather than a tourism corridor. Demand is seasonal and specific.	Hermosa sits on the road to Custer State Park, which makes short-term rental a real question here. Nothing in the public record confirms a town ordinance either way, so confirm with the town before you count on the income.	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.

Daily errands
Groceriesdiffers	Lynn's Dakotamart is a full-service grocery store in town.	Nothing full service in town. Hot Springs, about 14 miles south, is where errands happen.	Pop's Grocery Shoppe on North Ferguson Street, a full grocery in town since 2007. Anything larger is Rapid City, 26 minutes north.	Nothing in town. Spearfish is eleven miles southeast and Belle Fourche thirteen northwest.
Healthcarediffers	Monument Health Custer Hospital and clinic are in town.	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.	No clinic in town. Monument Health Rapid City Hospital is about 22 minutes north, and Monument Health Custer Hospital is about 27 miles southwest.	Monument Health Spearfish Hospital, a 35 bed facility with a 24 hour emergency department, about 18 minutes away.
Recreationdiffers	Custer State Park at the door, including Sylvan Lake, the Needles Highway, the wildlife loop and the September buffalo roundup.	Buffalo Gap National Grassland, hunting, rock collecting and OHV country, with the Cheyenne River nearby.	Custer State Park is the back door, with Battle Creek running at the edge of town and the Buffalo Gap National Grassland to the east.	Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away.
The trade
Housing and patterndiffers	A county seat at a park entrance, with a replacement Monument Health hospital and acreage starting just past the city limits.	A nearly intact turn-of-the-century western streetscape on the National Register, mostly quiet, at the gate to the grassland.	A working prairie town with its own grocery, library and county fairgrounds, at the point where the grassland meets the Hills.	An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor.
What you gaindiffers	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.	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.	Elementary and middle school in town, 26 minutes from Rapid City, with larger lots and rural utility tradeoffs common outside town.	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	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.	No school, no store and no services in town, an aging water system with an open compliance item, and an undocumented sewer situation.	High school is 27 miles away in Custer, and the water arrangement changes parcel to parcel.	A three-way school district split you have to verify per parcel, and no services of any kind in town.

St. Onge: About 45 milesDistance only. Drive time is not measured for this community, so time it from the parcel.

Winter drivingdiffers

Custer: Winter roads are a genuine planning factor at this distance, and on acreage you need to know who maintains yours.
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.
Hermosa: US 79 is state maintained and is the reason the commute works. Town streets and county roads clear on their own schedule.
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

Custer: Median sold $627,000Black Hills MLS, single family, trailing 12 months, as of August 2026. 7 closed sales, small sample.
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.
Hermosa: About $650,000 average sold, 28 sales over 24 monthsAverage sold $648,229. Black Hills MLS, single family, 24 months through August 2026, as of August 2026. 28 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.

Housing agediffers

Custer: Mixed ages. Older homes near the core, newer construction toward the edges.
Buffalo Gap: An 1885 to 1939 historic core with an aging housing stock and about a fifth of units vacant.
Hermosa: A mix, with older in-town stock and newer building on the edges.
St. Onge: An 1891 townsite with genuinely old buildings, surrounded by ranch and acreage property of every era.

New constructiondiffers

Buffalo Gap: Acreage parcels are common here
Hermosa: Acreage parcels are common here

Hermosa: Small town lots inside the limits, acreage outside them.
St. Onge: Small townsite lots, with acreage and ranch ground around them.

Covenants and HOAdiffers

Utilities and rules

Utility patterndiffers

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

Waterdiffers

Custer: Municipal water inside the limits, a private well or a district system outside them.Read off the townwide utility pattern in the guide. The service address controls, so confirm the provider before you write an offer.
Buffalo Gap: Town of Buffalo Gap municipal water from a single well, serving about 93 connections. Rural parcels are on private wells.
Hermosa: Town of Hermosa water inside the limits. The Hermosa Water Users Association is a separate system, and rural parcels are commonly on private wells. Which one serves a given address has to be checked address by address.
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.

Sewerdiffers

Custer: 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.
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.
Hermosa: Town sewer with lagoon treatment inside the limits, currently being expanded. Rural parcels are on private septic.
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

Custer: Grandfathered permits are non transferable and expire when the property sells, and the rules flip at the city line.
Buffalo Gap: This is hunting and grassland country rather than a tourism corridor. Demand is seasonal and specific.
Hermosa: Hermosa sits on the road to Custer State Park, which makes short-term rental a real question here. Nothing in the public record confirms a town ordinance either way, so confirm with the town before you count on the income.
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

What you gaindiffers

Custer: 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.
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.
Hermosa: Elementary and middle school in town, 26 minutes from Rapid City, with larger lots and rural utility tradeoffs common outside town.
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

Custer: 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.
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.
Hermosa: High school is 27 miles away in Custer, and the water arrangement changes parcel to parcel.
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.
