Professional Service — Big Sky, Montana
Big Sky is one of Montana's most demanding places to build with steep mountain terrain, a short construction season, and some of the highest value properties in the state. We bring the precision and equipment that steep slope excavation requires, from ski-in lots near Lone Mountain to properties throughout the Gallatin Canyon corridor.
Excavation & Site Preparation in Big Sky, MT
Why Big Sky Chooses Hennessy Development
Big Sky is unincorporated which means there's no city government here. Land-use and permitting decisions run through Gallatin County and the Big Sky Resort Area District rather than a local city office. Therefore, knowing exactly who to coordinate with matters more here than almost anywhere else in the valley. We've worked that process directly and navigate it for our clients.
Building here also means working with real mountain conditions: steep grades, rocky terrain, and a construction window that's meaningfully shorter than Bozeman's due to elevation and winter weather. We plan every Big Sky project around those realities from the first site visit, not after equipment is already on-site.

Frequently Asked Questions
-
Land use and building permits are handled through Gallatin County, with additional coordination through the Big Sky Resort Area District for certain projects because Big Sky is unincorporated. We navigate this process directly so you don't have to figure out which office to contact.
-
Big Sky’s terrain is steep slopes, rocky ground, and limited access on many lots which means more time and specialized equipment compared to a flat valley-floor site. We assess terrain during your free estimate so you have a realistic timeline before work begins.
-
Big Sky's building season is typically late spring through early fall for most excavation work. The elevation here is why there is a shorter construction window than Bozeman. We help plan project timing around this so weather doesn't derail your schedule.
-
Yes. We do both new construction site work, as well as excavation, grading, and more for existing homes, including drainage corrections, road work and driveways which are common on steep mountain lots.
