I'm an architect as well and I'm going to add an Accessory dwelling unit to it as well.

Based on the zoning you will find out if a MIL or Accessory Dwelling Unit (ADU) is allowable. 

This property is zoned U-SU-C1 which allows for Accessory Dwelling Units.

It was adding an accessory apartment in a bungalow.

Hello Bigger Pockets members,Here is the potential deal: 18 unit portfolio over three adjacent parcels including 2 multifamily apartment buildings, one mixed use building with a storefront and a 2 unit ADU (accessory dwelling unit behind it), a two stall garage, and vacant lot.

With regards to finding something that would be workable for you and them, have you thought about finding a property with a detached garage, putting in an accessory dwelling unit (ADU), and then renting out the front house to your parents, and the back house to another person?

Because its detached from the house would i have to call it an accessory dwelling unit?

It is what is termed an accessory use, meaning it has to go with something else i.e. a residence. 

Hi,So my friend is building a ~600 sq foot ADU (Accessory Dwelling Unit) in their backyard to be rented out as a "private residence" (think of it like a 1 bedroom studio/apartment with its own living space/bedroom/bathroom. 

What my wife and I ended up doing is remodeling the house with an addition and converted the garage into an Accessory Dwelling Unit (permitted and rentalble guest house with separate address and electrical meter).
