Basement Remodel FAQs, answered by experts

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.
