How much does it cost to finish a basement in the Twin Cities?

Finishing an open basement typically runs about $35,000 to $70,000. Adding a bathroom and wet bar brings most projects to $70,000 to $110,000, and a full suite with an egress window runs $110,000 and up. These are 2026 south-metro ballparks, not a quote.

Do I need a permit to finish my basement?

Yes. Finishing a basement in Minnesota needs a building permit, plus permits for the electrical, plumbing and mechanical work, with inspections along the way. We take care of the permits and schedule every inspection.

Can you add a bedroom in the basement?

Yes, as long as it has a code-compliant egress window and well for escape and rescue. Many basements need one cut into the foundation, and we handle the excavation, the window and the permit as part of the project.

What about moisture and radon?

We look for signs of water before we finish anything and deal with the source first. We also recommend a radon test: the Minnesota Department of Health estimates about 2 in 5 Minnesota homes have radon levels that pose a significant health risk, and mitigation is simplest before the walls close up.

Can you finish a basement in the winter?

Yes. Nearly all of the work happens indoors, so winter is a great time to finish a basement, and it's often an easier time to get on a schedule. If your plan includes an egress window, we'll talk through the timing for that excavation.

Can you add a bathroom or wet bar?

Yes. Bathrooms, bedrooms and wet bars are common parts of our basement projects. If your slab already has a bathroom rough-in, that's a head start.

Does a finished basement add value?

Finished lower levels are one of the most cost-effective ways to add usable living space and equity to your home.

Turn unused square footage into your family's favorite room.

Your basement is some of the most valuable untapped space in your home. Whether you're picturing a family room, a home theater, a guest suite or a wet bar, we'll help you make the most of it, and if you're not sure how to use the space yet, that's part of the design conversation.

Finishing a Minnesota basement well starts before the framing. We look for signs of moisture, recommend a radon test, and insulate and seal the walls so the finished room stays warm, dry and comfortable through the winter. If you want a bedroom down there, it needs a code-compliant egress window, and we handle cutting the opening and installing the window and well.

Most south-metro basements fall into two groups. Homes from the 1970s and '80s often have a partly finished lower level with paneling, low soffits and a dated bath that needs a full redo. Newer homes usually have a bare basement, sometimes with a bathroom rough-in already in the slab, which makes a great starting point. Our Minnesota basement guide walks through both.

We handle the whole job under one roof: framing, insulation, electrical, plumbing, heating, drywall, flooring and trim, with the permits and inspections taken care of and one written price before construction starts. Most basements take about six to twelve weeks of construction.
