I have a house in san jose downtown zoned R18 (Single family house with a ADU(Accessory Dwelling Unit) - In law unit.

I ended up getting it approved rezoned and permitted to convert it into an accessory dwelling unit. once its inspected and passes i can legally rent it out

It would be required to be zoned for a duplex or to allow for an Accessory Dwelling Unit (ADU).

The fence tucks underneath and so do all the accessories.

Because it is a detached garage, known as an accessory building, adding a dwelling within would make the lot have two buildings/structures on it.

Hello BP Community,I wanted to reach out and get opinions from local flippers/rehabbers who have done accessory unit additions in orange county california.I have gotten quotes ranging from 150-200/sqft to almost 250/sq to build a new accessory unit and I am trying to dial in a better estimate to figure out what the cost/benefit might be and if this might be a deal. 

In San Jose and per codes I’m allowed to build an accessory Dwelling unit in my backyard.

You may have to get creative...find a duplex in a good area and Airbnb the units or find an SFR with a legal accessory dwelling unit and live in the smaller unit while renting out the main etc. 

But don't add a stove and don't get it permitted as an in-law/ADU (Accessory Dwelling Unit).

Or ideally a home that has a legal “Ohana” (family) house or permitted ADU( Accessory Dwelling Unit).
