Unpermitted Studio in San Diego ........

[Edward Mac]

Hi!

I'm recently viewed a "Three Unit" property in San Diego. After walking the property I found out the the two story "2 unit" building in the back is actually a permitted 1 bedroom 1 bath and an unpermitted studio. The building was all built at the same time and is very nice, which actually raises more questions as to why the "studio" is not permitted. The "studio" has a bathroom, fridge and kitchen sink (but no oven). 

Does anyone know the process/obstacles that I should be thinking about? 

Thanks for your help!
