Property in or around City Heights

[Johnathan J Goodwin]

I found a property that is partially in an Open Residential Zone (OR-1-1) and I was hoping to an add an ADU to this property. Was thinking due to size of the house could easily be 900sqft 2BR detached, but I have no idea what the OR-1-1 will deter. And the land has a pretty good grade so I'm not sure if it will be allowed on that account as well.

Not to mention the current owners seemed to have added a room to the basement with a bathroom. I believe this is not a permitted room as the realtor kindly mentioned as benefit, "it isn't included in the square footage." I don't know until I speak with someone, but I'm curious to if this would prevent the ability to add a detached unit. 

Any advice/contacts are greatly appreciated!

You can have 1 ADU and 1 JADU in addition to 1 SFR.

Pretty clear that basement room is not permitted, but would make for a JADU. You would have to ensure it's up to code which could be a pain to do. If you know a good contractor have him take a look, or there is a company near you, Maxable, which specializes in ADU/JADU's. They can help you. Get all the info you can from the current owner, especially since he was the owner who did the work. He could have plans, drawings, receipts etc.

Which leaves you with the ability to build an ADU. Don't think the zoning would have any effect at all on the ADU/JADU. Only thing to worry about is how many dineros you have in your wallet.
