Big Sky is a purpose-built resort community in the Northern Rockies of southwest Montana, about an hour south of Bozeman and just north of Yellowstone National Park. The area was historically ranchland until television news anchor Chet Huntley assembled large tracts of land in the late 1960s and early 1970s and opened Big Sky Resort for skiing in 1973. The resort quickly became the anchor for a village of hotels, condominiums, and seasonal homes clustered around the lifts.
The first generation of condominiums at Big Sky followed immediately after the resort’s opening. By the mid-1970s, small housing developments, condos, and shops had appeared in two main nodes: Mountain Village at the base of the lifts on Lone Mountain, and Meadow Village around the new Big Sky golf course down the valley. Early condo clusters such as the Hill and Stillwater/Deer Lodge–area buildings provided ski-in/ski-out or shuttle-served access for vacationing families who preferred a kitchen and living room over standard hotel rooms.
Construction was rapid and, in some cases, relatively basic by today’s standards. Contemporary reporting and local histories describe miles of water and sewer lines laid quickly into rocky soils and early condo structures that sometimes required major renovation or replacement within a few decades. Even so, these pioneering projects established Big Sky’s identity as a condo-oriented, village-style ski resort rather than a collection of scattered second homes.
Through the 1990s and 2000s, new master-planned communities such as Moonlight Basin, Spanish Peaks and, nearby, the private Yellowstone Club extended the resort footprint around Lone Mountain. Each added its own townhome and condo developments, usually organized around ski lifts and golf courses. At the same time, Big Sky Town Center in the valley evolved as a walkable core with shops, restaurants, and mixed-use buildings that stack condominium residences above ground-floor commercial space.
Since the 2010s, the most visible new condos have often been attached to or near high-end hotels and branded residential projects, including the Summit and Shoshone in Mountain Village, slopeside and golf-course townhomes in Moonlight Basin and Spanish Peaks, residences at Montage Big Sky, and ultra-luxury club and branded units in developments such as One&Only Moonlight Basin and Yellowstone Club. Recent projects emphasize larger floorplans, modern mountain architecture, extensive amenities, and direct lift access.
Big Sky (the census-designated place) had about 3,500 total housing units in 2020, with more than half recorded as vacant because they are second homes or short-term rentals rather than year-round residences. A large share of this stock is in condominiums, townhomes, and other multifamily buildings rather than detached houses, especially in Mountain Village, Moonlight Basin, Spanish Peaks, and Town Center.
Because official data do not separate condos cleanly from other housing types, any count is approximate. Combining local planning documents with the number and size of known condo and townhome projects suggests that the Big Sky area likely has on the order of 1,500–2,000 attached units (condominiums, townhouses, and similar multifamily vacation properties), with additional inventory in nearby club communities that function as part of the same resort ecosystem.
When the first Big Sky condos were built in the mid- to late-1970s, typical new homes in the United States sold for only tens of thousands of dollars, and early resort condos at Big Sky appear to have been priced somewhat above that level but still broadly accessible to upper-middle-income ski families. By today’s standards, those prices were extremely low.
In contrast, Big Sky has become one of the most expensive mountain markets in North America. Recent data show an overall median sale price around $3 million for homes in Big Sky, with average home values near $1.8 million. Resort-area condos and townhomes span a wide range: older studios and one-bedroom units often list in the $500,000–$900,000 range, while newer three- and four-bedroom slope-side and club-branded residences regularly sell for several million dollars. At the ultra-luxury end, some multi-level condo and residence-club units in club communities or attached to five-star hotels can trade well above $5–$10 million.
From an energy and resource perspective, typical Big Sky condos and townhomes are generally more environmentally efficient than very large detached homes. Condos tend to be smaller in floor area, share walls with neighboring units, and concentrate infrastructure such as roads and utility lines. National energy surveys show that households living in large apartment or condo buildings use far less total energy per household than those in detached single-family houses, largely because there is less exterior surface to heat and cool and fewer square feet per household.
A compact, 1,200- to 2,000-square-foot condo will almost always have a lower total operating energy demand and greenhouse-gas footprint than a 7,000-square-foot single-family home in the same climate, even if the larger home is built to modern energy codes. However, the overall impact still depends on design details (insulation levels, windows, heating systems), how often the property is used, and how occupants travel to and from the resort.
When Big Sky’s first condos were built in the 1970s, land-use controls were limited and environmental review of resort development was relatively light. Since then, both Gallatin and Madison Counties and the State of Montana have adopted much more detailed zoning, subdivision, and environmental standards.
Today, the Gallatin Canyon/Big Sky Zoning Regulation and Madison County Subdivision Regulations govern density, building placement, and infrastructure, including detailed requirements for water supply, sewage disposal, stormwater management, and open-space protection. Big Sky Water & Sewer District has invested heavily in a state-of-the-art water resource recovery facility that significantly increases wastewater treatment capacity and sharply reduces nutrients discharged to the environment. New projects often must show how they will connect to centralized treatment, manage runoff, and avoid degrading the Gallatin River and local groundwater.
Wildfire-resistant design, building codes for heavy snow loads, avalanche-hazard considerations, wildlife corridors, and design review by local associations and resort master developers also play a much larger role today than in the 1970s. These requirements add cost and complexity but help address risks that were largely unregulated in the resort’s early decades.
Big Sky has an unusually high share of vacant units at any given time because many condos and townhomes are second homes or investment properties. A significant portion of the condo and townhome stock participates in short-term rental programs through the resort, local property managers, and platforms such as Airbnb and VRBO.
Owners commonly rent their properties during peak winter and summer seasons to offset carrying costs such as HOA dues, property taxes, and mortgage payments. State lodging taxes, county health permits, and local zoning rules now regulate these rentals, and some associations either require or restrict short-term rental activity. At the same time, the popularity of short-term rentals has contributed to a shortage of housing that is affordable for local workers, prompting local housing-trust initiatives and discussions about how to balance tourism income with community stability.
Several forces could shape or constrain the future of condo development at Big Sky:
Big Sky’s condo story begins in the 1970s with modest, quickly built slopeside and golf-course units and has evolved into a complex mix of older village condos, valley townhomes, and ultra-luxury branded residences woven into a large, year-round resort. Today’s condominium landscape reflects tighter environmental regulations, higher construction standards, much higher prices, and an ongoing tension between vacation-oriented development, local community needs, and the environmental limits of a high-alpine watershed.
