Add Residential Units To Existing Mixed Use Zoned Property (CA)?

[Christian Kurt]

I am getting ready to make an offer on an existing mixed use property that is zoned for storefront retail  + residential units in San Diego, California.  Does anyone have a private lender that will lend on the acquisition of the property and provide funds to pay for permitting, legal, architect, structural engineering, demolition work, etc. to add residential units to the second floor (possibly adding a third floor, checking on height restrictions)?  We are commercial general contractors and demolition contractors.  Will sell to investor groups after completion. 

Any other advice in general  on a mixed use redevelopment (what I call repurposing) project is much appreciated.
