Hi Daniela,

Some of the costs can go up or down based on finishes, permitting, plan development, etc. A very rough number that I've heard lately is $190-200 (or more) per square foot for construction/additions. Other factors, as mentioned above can come into play. For example, if you add over a certain square footage, there are "taxes" that the San Francisco levies onto a project.

It would be best to begin talking with some contractors or architects to give you a more accurate figure. Myself or other realtors on Trulia can give you a variety of referrals.

Good luck!
