SoCal - What's your experience with permitting existing room SFH?

[John Negron]

Hi there, 

I'm diving into real estate investing and found a property that the city has it listed as a 2 bedroom. The house has 3 bedrooms and the build looks pretty good. The city planning dept says I need to draft a plan for the 3rd bedroom to get it updated to a 3 bdr. 

Have you gone through that process? Did you need an architect or could a draftsman do it?

Thanks a lot!
