In America's biggest cities, a home with an ADU is priced 35% higher on average than a home without one
Even if zoning is ineligible, ADU could still be eligible with certain conditions
Here are some of the Basic Requirements to be considered an ADU:
The accessory unit must be smaller than the primary home.
There must be a separate entrance
The kitchen in the unit must have cabinets, a countertop, a sink with running water, and a stove or stove hookup.
There must be a sleeping area.
Bathroom Facilities and a bathing area are required.
A manufactured home that is permanently affixed to the property sometimes qualifies.
Allowed zoning for accessory units.

A living area over a garage.
A living area in a basement.

Normally, most lenders can approve a maximum of one ADU for single-family residences (SFR) and 2-3 units, while four units are not eligible. Additionally, the rental income from an ADU unit is typically allowed in the case of an SFR purchase.
