What a detached garage costs in Duluth.

The honest numbers
What’s in that
$45k–$80k.
That range covers the whole job as one contract — no coordinating a concrete crew, a framer, and a door company yourself:
- Slab or foundation. Poured and set to carry the building for decades.
- Framing to a real snow load. Squared and braced for Northern Minnesota winters, not just to hold a roof up.
- Roofing & siding matched to your home. The garage reads as part of the property — that’s most of the difference from a kit.
- Overhead & service doors. The doors you drive through and the walk-in door you use daily.
- Permit & cleanup. We pull the permit and leave the site clean.
What pushes the number up: a third bay, heated shop space, a loft with stairs, extra-tall walls for a lift or RV door, and site work if the slab location needs real excavation. We size all of that into the design up front so the slab and framing are right from day one.
Slab through doors, roofed and sided to match your house. The exact number depends on doors, windows, and your site.
Once the slab is in. A straightforward two-car lands at the short end; a bigger building with a finished loft runs longer.

How much does a detached garage cost in Duluth, MN?
In 2026, a standard 24×24 two-car detached garage in the Duluth area typically runs roughly $45,000 to $80,000 built to match your home — slab, framing, roofing, siding, and doors included. Larger buildings, shop space, or a loft push it up from there. The written estimate is free.
What adds the most to the price?
Size first — every added bay is slab, framing, roof, and a door. Then a finished or heated shop, a loft with stairs, extra-tall walls for a lift or RV door, and site work if the slab location needs real excavation or fill.
How long does it take?
Most detached garages are built in 4 to 8 weeks once the slab is in. A straightforward 24×24 lands at the short end of that range.
Do you handle the permit and the slab?
Yes — it’s one job with one contractor. ProCon pours the slab, pulls the permit, and runs everything through to the doors, licensed in Minnesota under #QB807406 and insured.
