A 900 square foot basement usually runs about $50,000 to $74,000.
We price basements by the square foot because they scale predictably. The base range already includes finishes and materials we'd choose for our own homes.
Your choices on the items below decide where your basement lands in this range:
Pricing updated April 2026. Ranges cover design, planning, demolition, cleanup, labor and materials for homes in Greater Grand Rapids and West Michigan.
Most Grand Rapids basements sit unfinished or underused. Here's what homeowners most often ask us to build.
Comfortable gathering space for movie nights and everyday relaxing, with lighting and wiring planned for your screen and sound.
Private, welcoming rooms for visitors. We add the egress window a legal basement bedroom requires.
Quiet, well-lit rooms built for focus, away from the noise of the main floor.
Kitchenettes, wet bars and game areas made for hosting friends and family.
A personal workout space at home, with durable flooring and good ventilation.
Safe, fun space for kids, with storage that keeps the clutter off the main floor.
When we give you a number, it isn't a materials-only guess that grows later. Here's what's built into every basement we quote.
Change orders. If we open a wall and find water damage, old wiring, or anything else outside the original scope, that's a change order. It's the only thing your quoted price doesn't cover. We'll show you what we found and what it costs to fix before we touch it, so you're never surprised by an invoice.
Our design-build process gives you a single point of contact. We handle design, permits, trades and scheduling so you don't have to.
We publish our basement pricing. You'll see every choice that shapes your number before anything gets torn out.
We check for moisture first and plan barriers, subfloors and insulation around it. When waterproofing is needed, we bring in trade partners we trust.
Job tracking software gives you a clear, visual timeline, so you know when each phase starts and when our team will be at your home.

Basement finishing with TPC Construction runs $56 to $82 per square foot. A typical 900 square foot basement costs about $50,000 to $74,000. Adding a bathroom or wet bar, egress windows, and custom built-ins moves you toward the top of the range. Our pricing guide breaks down every cost driver.
Construction on a full basement finish usually takes about 11 weeks, and most of our projects land between 8 and 14 weeks. From your first call to the final walkthrough, plan on roughly six months, because design, planning, permits and scheduling take about as long as the build. Smaller jobs, like adding an egress window, can be done in a few weeks.
Basement finishing usually means taking an unfinished space and making it livable with drywall, flooring, lighting, and basic fixtures. Basement remodeling goes a step further, reimagining the space with features like custom layouts, bathrooms, wet bars, or entertainment centers. At TPC Construction, we offer both, depending on your goals.
In most Grand Rapids-area communities, yes. Finishing a basement usually involves framing, electrical, plumbing and mechanical work that needs permits and inspections. TPC pulls and manages the permits for your project, so you don't have to deal with the city or township yourself.
Yes, as long as it has a proper emergency exit. Michigan's residential code requires an escape and rescue opening, usually an egress window, in every basement bedroom. We install egress windows, including cutting the foundation and adding the window well, as part of your project.
Before construction starts, we evaluate the space for moisture and waterproofing needs and recommend solutions such as sump pumps, drainage systems, vapor barriers and raised subfloor systems. When waterproofing work is needed, we bring in trade partners we trust to deliver the same quality TPC is known for. Handling moisture up front protects your finished basement long-term.
Yes. Many homes in Grand Rapids and East Grand Rapids were built decades ago, and their basements weren't designed with modern living in mind. We specialize in updating older spaces with improved insulation, moisture control, and smart layouts that respect the character of the home while adding today's comforts.
For most families, yes. Finishing a basement adds usable living space for far less per square foot than building an addition: $56 to $82 per square foot versus $155 to $350 for an addition. In neighborhoods like East Grand Rapids, Ada and Forest Hills, finished lower levels are especially desirable to buyers.
