Garage conversions in the Twin Cities
An attached garage is already framed, roofed, and inside your foundation footprint — which makes it one of the cheapest ways to add real living space. The catch in Minnesota is that a garage was never built to be lived in: the slab is uninsulated and sloped, the walls are thin on insulation, and there is no heat.
What has to change
- Floor: level the slope, add rigid insulation and a sleeper or subfloor system so the floor is not freezing in January
- Walls and ceiling: bring insulation up to current Minnesota energy code
- Heat: extend the ductwork or add a ductless mini-split
- Egress: a bedroom conversion needs a compliant window; we usually infill the overhead door with a framed wall plus a window
- Electrical: rewire from garage-grade to living-space circuits, add alarms
- Zoning: some cities require you to keep off-street parking. We check before you commit
- Exterior: siding, trim, and windows that read as house, not as a filled-in garage door
Rough cost
| Scope | Typical range |
|---|---|
| Office, studio, or flex room | $18,000 – $32,000 |
| Bedroom with egress and heat | $24,000 – $42,000 |
| In-law suite with 3/4 bath and kitchenette | $45,000 – $85,000 |
Planning ranges. The overhead-door infill, the floor build-up, and the bathroom plumbing are what swing the number.
Is it worth it?
It depends on your block. In neighborhoods where off-street parking is scarce, losing the garage can cost you at resale. In neighborhoods where an extra bedroom or a rentable suite is the scarce thing, a conversion is one of the highest-return projects available. We will tell you honestly which one your house is before we quote it.

FAQ
Can I convert my garage into a bedroom?
Usually yes, if zoning allows and we can get a compliant egress window and permanent heat into the space. Some cities require you to keep a certain amount of off-street parking, so we check zoning first.
Do I need to insulate the garage floor?
In Minnesota, yes. A bare slab with no insulation is unlivable in winter. We level the slope and build up with rigid foam and a subfloor.
What happens to the overhead door?
We frame it in, insulate it, and finish the outside with siding and a window so it matches the house rather than looking like a filled-in door.
Will it hurt my resale value?
It can, in areas where garage parking is at a premium. In other neighborhoods the added bedroom or suite is worth far more than the stall. We will give you a straight read on your block before you commit.
How long does a garage conversion take?
Typically 4 to 8 weeks depending on whether plumbing is involved and how fast inspections schedule.
