San Diego Duplex to Triplex

Hello all,

I'm in contract on a duplex in San Diego and have a question for the community about turning it into a triplex, rather than a adding an ADU. I had an architect tell me today that because of fire codes in the city, they will not permit a 3rd unit the front door rear facing. For local investors, @Justin R., @Dan H., @Colin L., etc.  Does that sound correct?  I've gotten several opinions on this property but today is the first I have heard that the units have to be facing the street to be permitted.  Does that sound correct?

The property is zoned RM1-1 and has 10K sq ft, which allows for a 3rd unit in addition to the existing duplex.  It also has enough space to fulfill the parking requirements of 7 spots.

Thoughts or feedback would be appreciated!
