Cost per square foot to add on - Southern Calif

[Joffrey Long]

I usually rehab and manage, but rarely add square footage. Now I am. Considering addition of 2 bedrooms and one bath to an existing dwelling in Southern Calif. All one story, will be average quality construction, and is in a section of the municipal City of Los Angeles that does not have architectural committees or anything else outside of normal building codes.

Assuming no major issues with adding to the existing dwelling, trying to get a general idea of per foot cost. Would already have a lower cost architect draw plans, then hand plans to contractors to obtain bids from contractor with them pulling permits and then doing the job.

Would appreciate feedback on this from anyone actually familiar with Southern Calif. building / remodeling costs. Thanks in advance.
