For many prospective buyers in the Bay Area, location is the key factor driving a home purchase, whether it’s to live near the office, within the boundaries of a certain school district, or in close proximity to family and friends.
For others, however, a home’s size may be of particular importance – especially for growing families who want to upgrade their space or empty-nesters who no longer need a sprawling house in the suburbs.
We took a look at October MLS data as of Nov. 18 to determine the average price per square foot for single-family homes in our Bay Area regions, as well as towns and cities where buyers paid the most and least for the average amount of space.
We also assembled a list of the 10 most expensive and affordable cities in terms of square footage; scroll down to see the charts.

In October buyers paid an average of $384 per square foot across Contra Costa County, a year-over-year increase of 16 percent.
Homes in Martinez are the most affordable in Contra Costa in terms of square footage, an average of $277 – 28 percent cheaper than the county average. At $280 per square foot, Concord was the only other city in the region under $300 per square foot.
