Hi Mary,

I have worked with many home owners and Investors who have added square footage and/or done improvements. I am working with one investor who is building a house in Pleasanton. Depending on the contractor and the city, price can rage anywhere starting from $100 SqFt. My client uses a contractor and depending on the project he charges around $150/ SqFt.

You are asking this of a bunch of Realtors - you would be best off asking a general contractor. There are a lot of factors involved and costs can be very high to add a second story. As Pacita suggested, it's best to start with the local planning department to see what they will or will not allow.

The basic price for the actual construction will be in the neighborhood of $225-$250 a sq/ft, plus building fees, architect, foundation reinforcement and SO much more. Depending on the final outcome, your costs could be as high as $450 sq/ft.

You can find a good contractor through sites like Angie's List or Service Magic.

The first thing your friend should determine is whether or not the current building code and zoning will allow an expansion.

Concurrently, he should engage a structural engineer or construction professional to determine if the current structure can support a second floor.

And whatever your friend finds out and decides to do, he should make sure that he gets his contractor to pull permits for the renovation, etc.

Good luck.
