What Is the Most Expensive Part of Finishing a Basement?

The most costly aspects of finishing a basement typically include:

  • Framing and Drywall – Creating separate rooms and defining spaces adds to labor and material costs.

  • HVAC, Plumbing, and Electrical Work – Extending heating, cooling, and electrical systems can be a significant expense.

  • Flooring – Luxury vinyl, tile, or engineered wood flooring adds durability but increases costs.

  • Bathroom Additions – Installing a bathroom in the basement requires plumbing work, which can be expensive.

  • Custom Features – Bars, theaters, and built-ins can raise the price significantly.

Is Finishing a Basement Worth the Money?

Yes! A finished basement can provide extra living space, increase home value, and improve functionality. Homeowners typically see a 70-75% return on investment (ROI) when selling a home with a finished basement. Plus, it can serve as a guest suite, rental unit, or entertainment area for additional income opportunities. 

How Much Value Does a Finished Basement Add?

On average, a finished basement can increase your home’s value by 10-20%, depending on the quality of the renovation and local market trends in Missouri. If done right, a basement remodel can make your home more attractive to buyers, offering additional usable square footage without expanding the home's footprint.

How Long Does It Take to Finish a Basement?

A basement finishing project typically takes 6 to 12 weeks, depending on the scope of work. Factors affecting the timeline include:

  • Size of the Basement – Larger basements take longer to complete.

  • Complexity of Design – Custom features like bars, theaters, and bathrooms add to the timeframe.

  • Permits & Inspections – Some municipalities require multiple inspections, which can extend the process.

  • Contractor Availability – Hiring an experienced contractor like Morganco Design Build ensures efficiency and quality work.

Does a Finished Basement Count as Square Footage?

This depends on local real estate guidelines. In Missouri, finished basements generally do not count as part of a home’s official square footage since square footage usually only includes above-grade (above ground) living space. Even fully finished basements are often excluded from the total square footage if they are below-grade

Do I Need a Permit to Finish My Basement?

Yes. Most Missouri municipalities require permits for basement finishing projects, especially if you're adding electrical, plumbing, or structural changes. Working with a professional contractor ensures compliance with local building codes and avoids costly mistakes.
