Facts checked August 2026
Buffalo Gap has 131 people, a main street on the National Register of Historic Places, and a school district that does not match its county. All three of those matter if you are buying here.
Why buyers choose Buffalo Gap
- Eighteen minutes to a 25 bed hospital with a 24 hour emergency department and a clinic in the same building.
- A National Register historic main street with 1880s and 1890s buildings still standing.
- Buffalo Gap National Grassland, nearly 600,000 acres, at the edge of town.
- One MLS closing in 24 months, so there is no price level to quote here, only that one sale.
Things to consider
- The town is in Custer County but the school district is Hot Springs 23-2, and there is no school in town.
- The town water system carries an open certified operator compliance item and has aging cast iron mains queued for replacement.
- Sewer arrangement is not documented publicly and has to be confirmed with the town.
- Roughly a fifth of housing is vacant, the median age is around 66, and many historic commercial buildings are abandoned.
Why buyers choose Buffalo Gap
It is eighteen minutes from a hospital, which for a town of 131 people on the prairie is remarkable. Fall River Health Services in Hot Springs is a 25 bed critical access hospital with a 24 hour emergency department and a rural clinic in the same building, 13.6 miles away. A lot of much bigger places in this state cannot say that.
It is also a genuine piece of history rather than a town that put up a plaque. The Buffalo Gap Historic Commercial District is on the National Register, covering Main, Walnut and 2nd streets, with a period of significance from 1885 to 1939. An 1886 bank and land office building, Clark's Store from 1890, the 1892 Wilson Hotel, the 1899 Congregational Church, the 1908 auditorium, and a 1910 rusticated native sandstone bank that now serves as City Hall. The National Register description is honest about it: most of the buildings are abandoned, but the streetscape is still that of a turn-of-the-century western town.
And it is the gate it is named for. Buffalo Gap National Grassland runs to nearly 600,000 acres, stretching from Kadoka to the tri-state corner, and the town sits at the natural gap in the ridge that gave it the name. Hunting ground, OHV country and open prairie start where the last street ends.
The school district, which is the easiest mistake to make here
Buffalo Gap is in Custer County. Its kids go to school in Hot Springs School District 23-2, which is in Fall River County. The county line and the district line do not match, and assuming Custer County means Custer School District 16-1 is the single easiest error available on this town.
There is no school building in Buffalo Gap. The stone public school that opened in 1897 and the high school established in 1923 are both long gone. Students travel to Hot Springs, which is the same eighteen minute drive as the hospital. Confirm the assignment for the exact parcel with the district before you make a school-driven decision, and if you are considering open enrollment somewhere else, that is a conversation to have with both districts up front.
What is on the water system's record
The town runs its own water system from a single well, serving about 93 connections, with a low state susceptibility rating and detected contaminants within EPA limits. So the water itself tests fine.
Two things on the record that a careful buyer or an inspector will find, and that I would rather you hear from me. The system has been carrying an open compliance item for lack of a certified operator since 2024, re-noticed in 2025. That is an administrative and staffing violation, not a boil advisory and not a health-based exceedance. The town's own consumer confidence report states plainly that an alternative water supply was never needed. Separately, part of the distribution system is cast iron pipe past its useful life, and the town has a state-funded project queued to replace 2,750 feet of watermain at a cost above $1.3 million. That is good news for the system and it is reasonable to expect rate pressure from it.
Sewer I will not guess at. I could find no municipal wastewater project, no discharge permit and no town ordinance in the public record. The absence points toward private septic, but pointing is not knowing, and a guess does not belong on a page a buyer might rely on. On any purchase here we call the town finance officer and get the answer.
What homes cost here
One single family home sold in Buffalo Gap in the two years through August 2026. It closed at $80,000 after 218 days on market, at about $87 a square foot. There was one active listing when I pulled this, asking $1,749,000, which tells you these are not two points on the same line.
That is the whole transaction record for two years, so there is no average worth publishing and I am not going to manufacture one. The state's most recent city level sales study recorded four sales here in a year, and no newer study has been published.
The useful facts are the ones around the number: median age here is about 66, roughly a fifth of the housing is vacant, and many of the historic commercial buildings are described in the National Register record as abandoned. Condition is everything. Point me at a house and we can walk it together before you decide.

What to check before you write an offer
On any address you are serious about, buyer due diligence should include the school assignment from the district, the water quality report from the utility that serves it, and the assessed value and levy from the county. Here are the sources for each one.
The sources, by category
Schools
Confirm the assigned school for a specific address with the district, because boundaries change and they change more often than people expect. Rapid City Area Schools boundary maps · Douglas School District 51-1 · Meade School District 46-1 · Spearfish School District 40-2 · School and district profiles on GreatSchools · Preschools and private schools in the Black Hills
Crime data
Drinking water
Every public water system publishes an annual water quality report. Read the one for the system that serves the address you are considering, not the one for the town next door. Rapid City water quality reports · City of Box Elder Water Division · City of Spearfish water · EPA drinking water lookup
Property taxes and assessed value
Pennington County Equalization · Meade County Equalization · Lawrence County Equalization
The county record, the plat and the recorded covenants are the three documents to read on any address here. I do not rate schools and I do not characterize neighborhoods as safe or unsafe. Those readings are yours to make from the sources above.

These open my search site, where the listings update from the MLS through the day. This page is the background; that one is the inventory.
Can you rent it out?
This is hunting and grassland country rather than a tourism corridor. Demand is seasonal and specific.
The rules in detail
- Confirm any town requirement with the town finance officer. The town's website is being discontinued, so ordinances and minutes now come directly from that office.
- Renting 10 or more days a year requires a South Dakota sales tax license, and state lodging licensure applies.
- The statewide 4.2 percent sales tax and 1.5 percent tourism tax apply, plus any municipal tax.
- Realistic demand is hunting season on the grassland, OHV visitors and Rally traffic. It is not year-round.
Short-term rental rules change, and they change fast. This summary reflects my research as of August 2026 and is general information, not legal advice. If rental income is part of why you are buying, verify the current requirements with the city or county that has jurisdiction over the specific address, and read the subdivision covenants, before you write an offer.
Schools
Buffalo Gap sits in Custer County but belongs to Hot Springs School District 23-2 in Fall River County, and there is no school building in town.
School by school
- The district is Hot Springs 23-2, not Custer 16-1. The county line and the district line do not match here.
- There is no school in Buffalo Gap. The 1897 stone school and the 1923 high school are both long gone.
- Students travel to Hot Springs, about fourteen miles south.
- Have Hot Springs 23-2 confirm attendance for the exact parcel, and raise open enrollment early if you are considering it, because that conversation goes better in spring than in August.
I provide objective school information consistently and do not personally rate or recommend schools. Attendance boundaries can cross city and county lines, and the district's current assignment for the exact address controls. Verify directly with the district before making a school-driven decision.

Common questions
Which school district serves Buffalo Gap?
Hot Springs School District 23-2, in Fall River County, even though the town itself is in Custer County. This is the easiest mistake to make about Buffalo Gap and it would be a costly one. There is no school building in town, so students travel about fourteen miles to Hot Springs. Get the district to put the assignment for that exact parcel in writing before you build a decision around it.
Is there something wrong with the water in Buffalo Gap?
Not with the water itself. Detected contaminants are within EPA limits and the town's own report states plainly that an alternative supply was never needed. What is on the record are two administrative items: the system has been carrying an open compliance violation for lack of a certified operator since 2024, and part of the distribution system is cast iron pipe past its useful life, with a state-funded replacement project queued at over $1.3 million. Neither is a boil advisory. Both are public, and both are reasonable to expect rate pressure from. I would rather you hear it here than from an inspector.
Does Buffalo Gap have town sewer?
I do not know, and I am not going to guess on a page you might rely on. There is no municipal wastewater project, discharge permit or town ordinance in the public record that I could find, which points toward private septic but does not prove it. On any purchase here we call the town finance officer and get the answer in writing before closing.
How far is Buffalo Gap from a hospital?
About 13.6 miles and eighteen minutes to Fall River Health Services in Hot Springs, a 25 bed critical access hospital with a 24 hour emergency department and a rural health clinic at the same address. For a town of 131 people on the prairie, that is a short run to an emergency department.
