Finished Basements in Westminster: Permit, Egress and Value

• Permitted or not. A permitted finish was inspected for electrical, plumbing, egress and fire. An unpermitted finish is common in Westminster and it is where buyers find the surprises. We pull the permit history.
• Egress makes a bedroom. A basement bedroom without an egress window is a "non-conforming" bedroom and cannot be counted or safely slept in. The window costs $3,000 to $6,000 to add.
• Radon. Colorado soil puts radon in most basements. A test runs $150 and mitigation $1,000 to $2,000; both are standard in a Westminster contract.
• Water and the sump. Finished walls hide the foundation. We look at the sump pump, the window wells, the carpet edges and the smell.
• Appraised value. Below-grade square footage appraises at less per foot than the main floor, which is why a finished basement is the best-value space in Westminster.
