Finishing your basement is one of the most cost-effective ways to add livable space to your home. In South Lyon and Oakland County, most homeowners pay between $28 and $55 per square foot for a finished basement. For a typical 1,000 square foot basement, that works out to $28,000 to $55,000.
Here is a breakdown of what that money gets you and what factors affect your final price.
Basement Finishing Costs in Oakland County
| Project Level | Cost per Sq Ft | 1,000 Sq Ft Total | What Is Included |
|---|---|---|---|
| Basic Finish | $28 - $35 | $28,000 - $35,000 | Framing, drywall, basic lighting, LVP flooring, paint, egress window if needed |
| Mid-Range Finish | $35 - $45 | $35,000 - $45,000 | Everything above plus a bathroom, upgraded lighting, built-in storage, dedicated circuits |
| Premium Finish | $45 - $55+ | $45,000 - $55,000+ | Full bathroom, wet bar or kitchenette, home theater wiring, custom built-ins, tile flooring in wet areas |
What Adds to the Cost
- Adding a bathroom. A basement bathroom adds $8,000 to $15,000 depending on fixtures and whether a sewage ejector pump is needed. It is almost always worth it for resale and daily use.
- Wet bar or kitchenette. Running water, drain, and electrical for a wet bar adds $5,000 to $10,000. A full kitchenette with a sink, mini fridge, and microwave runs $8,000 to $15,000.
- Egress windows. Michigan building code requires an egress window in any basement bedroom. Cutting and installing an egress window typically costs $3,000 to $5,000.
- Moisture issues. If your basement has water intrusion, that needs to be addressed before finishing. Interior drain tile and a sump pump system can add $5,000 to $10,000.

How Long Does Basement Finishing Take?
Most basement projects take 6 to 10 weeks. A basic finish with no bathroom can be done in 4 to 6 weeks. Adding a bathroom, wet bar, or complex layout extends the timeline to 8 to 12 weeks. Permit approval in South Lyon and surrounding townships typically takes 1 to 2 weeks.
Is Finishing Your Basement Worth the Investment?
In Oakland County, finished basements consistently recoup 70 to 75 percent of their cost at resale. More importantly, you gain hundreds of square feet of usable living space at a fraction of what an addition would cost. A home addition runs $200 to $350 per square foot. A basement finish runs $28 to $55. The math speaks for itself.
