This is Kyle K in Member Care. I'm happy to help!

Although we don't track going rates for various projects because this varies widely depending on market factors and location, members are encouraged to include how much a project cost in their reviews.

When you're looking at a particular company's reviews, you can get an idea of the average costs. You can also compare this to rates charged by other providers in this category on the List.

Depends too much on specifics of the construction, modifications needed to make it legal habitable space (if even allowed at all by local building and zoning codes - check that first), quality of workmanship, issues with isolating HVAC equipment, whether a bathroom is being added, electrical and plumbing and HVAC modifications needed (and if existing HVAC and electrical, well, and septic systems are large enough for added load), etc.

For a bare-bones rough in with cheapo paint job you might get it done as low as around $20/SF in a low cost area - thoughh I have seen just the architect's bill or an upscale floor finish cost that much in higher end jobs.

If I had to throw out an off-the-cuff ballpark, I would expect at least $40-50/SF for normal, run of the mill upgrade for normal household interior finishes, to as much as $100-150/SF for nicer finishes or high cost areas. That for the living area, PLUS at least $10-30,000 for a normal full or 3/4 bath, which can bring your total nearer $100/SF in many cases. However, depending on your job specifics, local code requirements, and what level of finishes and materials you are using, could easily run anywhere from $20-200/SF.
