❓Common Questions

Homeowners in the Columbus area can expect a resale ROI of 65% to 75%, which is slightly higher than the national average due to the high demand for livable square footage in the local market.

Adding a bathroom typically costs between $8,000 and $25,000. The higher end of the range applies if the concrete slab must be cut to install new drain lines or if an ejector pump is required.

Columbus uses a flat-fee system rather than valuation-based math. A standard basement finishing permit (alterations) costs $385, and a combined MEP (Mechanical, Electrical, Plumbing) permit is $275, totaling approximately $660 for most projects.

Due to clay-heavy soil and a moderate water table, waterproofing is a frequent hidden cost, ranging from $3,000 for minor interior drainage to $15,000 for full exterior systems. Egress windows, required by code for bedrooms, average $1,000 to $3,500 each.
