A 3-bay shop with loft in Driggs runs $265k–$495k built stick-frame with a heated main floor and a 600–900 sf finished loft. Permits in 10–16 weeks through Teton County ID. Build in 5–7 months. Adds real resale value and gives you flex space above.
What’s a 3-Bay Shop with Loft in Driggs?
Typical footprint is 30×50 or 36×50: three overhead doors on the main floor (usually 12×12 or 10×10), full-height ceiling, plus 600–900 sf of finished loft space above with its own stairs and windows. The loft becomes a shop office, home gym, gear room, guest suite, or (with proper permit) an ADU.
Note for Teton Valley readers: Driggs city vs. unincorporated Teton County ID have slightly different lot coverage rules. And the loft use case changes the permit path — storage vs habitable vs ADU each go different directions.
Pros
- Doubles usable square footage per dollar. Loft costs ~40% of main floor per sf.
- Flexibility. Office today, gym next year, guest suite when kids visit.
- Adds real resale value. Buyers in Driggs value multi-use shop + loft space.
- Can be permitted as ADU later. If planned correctly at design.
- Better use of expensive TV land. Vertical square footage.
Cons
- Structural cost jumps. Second-floor loads mean beefier walls, engineered floor system, stairs.
- Loft egress adds cost. Windows sized for egress, staircase to code.
- Heating a two-story shop is more complex. Consider zoned mini-split for the loft.
- Higher permit review. Two-story structures get more scrutiny on setbacks and shadows.
- If you want it as ADU later, plumbing rough-in adds $8–$14k upfront.

When It Makes Sense — and When It Doesn’t
Makes sense: you need shop AND office/gym/guest space, lot has room, you may want ADU convertibility later, and you’re staying 5+ years.
Doesn’t make sense: pure storage need (single story is cheaper per sf), tight lot with height restrictions, or budget is truly capped at $200k.

FAQ
Can I use the loft as a guest bedroom?
Yes with egress windows + smoke detectors + heat. Full ADU is a separate permit.
What’s the timeline?
Permit 10–16 weeks + build 5–7 months = 8–11 months total.
Can I run water to the loft later?
Yes but pre-plumbing during build saves 5–10x.
How high can a shop be in Driggs?
Depends on zone. Most residential zones cap at 30–35 ft. Ag zones higher.
