Still waiting to here back from building and zoning if I'm able to do an accessory dwelling or if I need to split the parcel and build a separate single family. 

The owner of the property shall reside on the parcel on which the accessory dwelling unit is located.

But I would consider splitting that off into the separate unit for a rental when you sell ---  of course you'd want to run the numbers/explore the market to see whether the duplex or SFH would give you the best valuation.In an effort to produce more affordable housing, CA is in favor of garage conversions (amongst other things) to create ADUs ('accessory dwelling units'). 

You could also buy a SFH and build an accessory unit and get some pretty nice cash flow.

@Ben S.Sounds like a great idea to take back the parking and go for both the parking space and convert the garage into an ADU Accessory Dwelling Unit for that extra income.  

The home is a 2 bed 1 bath, 1144 sq. ft. rancher with accessory dwelling unit of about 900 sq. ft.

(Accessory dwelling units), and some specifically don't allow renting them for profit.Search for "accessory building" also.

Morning folks,Just a quick question regarding vapes.

CA enacted the Accessory Dwelling Unit law that says any SFR can have a 1200sq/ft building as an ADU, and I called the Assesors office and he said I could most likely get one of the buildings coded as an ADU BUT that may require ripping out the 2nd kitchen in the 'main house', which is a deal breaker.

@Chris Paez I'm not sure if an accessory unit would qualify for a 2-unit property.
