Sun Valley shop builds — what’s actually different up here
A shop in Rigby costs one thing. A shop in Ketchum costs something else. Three things drive the difference in Blaine County, and every serious builder should be able to walk you through all three before quoting a number:
- Snow load engineering. Ketchum is 100 psf roof live load. North of Ketchum runs 125 psf. West of Ketchum runs 110 psf. Unincorporated Blaine County can hit 150 psf. That drives trusses, purlins, foundations, and roof pitch — not marketing detail, real cost.
- Design review. Ketchum’s design review applies to detached outbuildings the same way it applies to main homes. Roof form, siding material, and setbacks matter. Hailey and Bellevue are lighter but not zero.
- Freight and sub availability. Wood River runs 25–35% higher on materials and labor than Eastern Idaho. Steel, concrete, and finish subs are booked out. We plan around it.
What kinds of shops we build in Sun Valley
- Heated detached shops (24×40 to 60×100). In-floor radiant, insulation package for 15–below-zero design temp, mudroom entry.
- RV barns and toy barns. 14–foot doors, drive-through options, hookups for full-size Class A.
- Shop-with-living-quarters. Loft apartment, kitchenette, bath. Check with Ketchum P&B on ADU classification — rules vary by zone.
- Detached garages with design review. 3-car and 4-car, matched to the main house architecture per design review board.
- Ag-style pole barns (in unincorporated Blaine County). Where zoning allows and design review doesn’t reach.
Real cost ranges — Sun Valley shop, 2026

Design review + permit — the part most GCs skip explaining
- City of Ketchum: Design review is mandatory for detached outbuildings. Submit through CommunityConnect. Timeline 8–14 weeks. Contact 208.726.7801.
- City of Hailey: Design review applies only in downtown / historic overlay. Standard permit path outside those zones.
- City of Bellevue: Loosest of the three. Standard IBC plan review.
- Unincorporated Blaine County: Mountain Overlay + Scenic Corridor overlays trigger county design review. Standard permit otherwise. Contact 208.788.5570.
