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.
25 of 25 communities
Price filters only consider communities with a published trailing twelve month median, so towns without one do not appear in a price filter.
The five facts that decide a shortlist
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.
- Typical price
- Unincorporated, so closings report under Rapid City and Meade County rather than a Black Hawk median. Lot size and outbuildings move the price more than the street does.
- To Ellsworth AFB
- About 30 minutes, the same I-90 run as Summerset just northDriving time and distance, off peak.
- To downtown Rapid City
- About 12 to 15 minutesDriving time and distance, off peak.

| Waterdiffers | City of New Underwood water inside the limits, drawn from two Madison Aquifer wells. Outside the limits, parcels are on small water associations or private wells. | City of Box Elder municipal | 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 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 | City sewer inside the limits. Rural parcels are on private septic permitted by Pennington County. | City of Box Elder municipal | 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. | 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 | New Underwood is a highway town rather than a tourism town, and no short-term rental ordinance surfaced in the public record. Confirm with the city before you count on rental income. | A verify first town for rental plans, with one specific misconception the guide clears up. | 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 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. |

Full grocery shopping is Rapid City, about 18 miles west. | Lynn's Dakotamart is a full-service grocery store in town. | Nothing in town. Spearfish is eleven miles southeast and Belle Fourche thirteen 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 | No clinic in town. The Monument Health Rapid Valley Clinic on Elderberry Boulevard has walk-in urgent care seven days a week, and the hospital is in Rapid City. | Monument Health Box Elder Clinic provides primary and urgent care in town. Hospital-level care is in Rapid City. | Monument Health Spearfish Hospital, a 35 bed facility with a 24 hour emergency department, about 18 minutes away. | No clinic in town. Monument Health Custer Hospital has a 24 hour emergency department, and Rapid City has the larger hospital. |
| Recreationdiffers | The municipal pool, with a donor-funded free swim program, and open prairie in every direction. | 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. | Creek bottoms, hay ground and hunting country, with Spearfish Canyon and the northern Hills half an hour away. | 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. |
| Mapped subdivisions | ||||

The recorded plat controls. | No recorded subdivision outlines drawn for this community yet. | No recorded subdivision outlines drawn for this community yet. |
| The trade | ||||
| Housing and patterndiffers | A prairie town with its own K through 12 campus and its own interstate exit, 18 miles from the city. | A young city building its first downtown at Liberty Plaza on 110 acres, with roughly 800 residential units planned. | An 1891 French-Canadian railroad townsite that is now a cattle auction crossroads and an acreage corridor. | An 1883 mining camp turned tourism town at the gateway to Mount Rushmore, 240 residents and millions of visitors. |
| What you gaindiffers | The only town this close to Ellsworth that still educates its own kids from kindergarten through graduation. | The Ellsworth main gate is in town, 9 minutes from most addresses, on city water and sewer, with the region's newest housing pipeline. | The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns. | 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 | You give up the grocery store, the clinic and the hardware store, and you inherit a small municipal water system with a publicly acknowledged supply question. | 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. | A three-way school district split you have to verify per parcel, and no services of any kind in town. | A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter. |

Winter drivingdiffers
- New Underwood
- I-90 is the commute and it is state maintained. Everything off the interstate is county and city plowing on its own schedule, and this is open prairie, so wind moves snow back onto the road.
- 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.
- St. Onge
- Highway 34 is state maintained and connects three directions. County and private roads off it are a different conversation.
- 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.

- Box Elder

- Box Elder
- City of Box Elder municipal
- 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.
- 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
- New Underwood
- New Underwood is a highway town rather than a tourism town, and no short-term rental ordinance surfaced in the public record. Confirm with the city before you count on rental income.
- Box Elder
- A verify first town for rental plans, with one specific misconception the guide clears up.
- 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.
- 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.

What you gaindiffers
- New Underwood
- The only town this close to Ellsworth that still educates its own kids from kindergarten through graduation.
- 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.
- St. Onge
- The cheapest ground in the northern Hills that still puts you eleven miles from a hospital and sixteen from three towns.
- 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
- New Underwood
- You give up the grocery store, the clinic and the hardware store, and you inherit a small municipal water system with a publicly acknowledged supply question.
- 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.
- St. Onge
- A three-way school district split you have to verify per parcel, and no services of any kind in town.
- Keystone
- A seasonal town with no school, no grocery and no clinic, and a housing stock where half the doors are dark in winter.
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.

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.
