Your question is nearly impossible to answer since there are so many factors that dictate price. In some instances, a difference of one city block makes a big difference in price. Also, there are very few new homes in Chevy Chase--most are renovations that are resold as "new". If I go by the most recent sale, however, MLS shows a newly built home that just sold for $1,415,000 with a taxable living area of 1,976 square feet. Taxable uliving area does not include basements so you can figure that the true square footage is about 2,800. If this is accurate, the cost per SOLD square footage in Chevy Chase is about $500. I'm sure you probably would rather know how much per square foot it would cost to build a new home in Chevy Chase. I'm not sure it would be very cost effective to try and build in Chevy Chase unless you already owned a piece of land.
