Q: Are walkout basements included in square footage?

• <div><p>Walkout basements are not generally included in a home&rsquo;s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.</p></div>

Q: Can you finish a basement with no windows?

• <div><p>Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.</p></div>

Q: How hard is it to add a basement to an existing house?

• <div><p>The difficulty of adding a basement to an existing house can vary depending on the house&rsquo;s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you&rsquo;ll need to enlist professional help for this project.</p></div>

Q: Does a finished basement count toward a home's square footage?

• <div><p>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.</p></div>

Q: Do general contractors require a down payment, and what is the typical payment schedule?

• <div><p>Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.</p></div>
