Homes with ADU
An accessory dwelling unit can add 15–40% to a property's value, generate $1,500–$3,500 in monthly rental income, and make a home qualify for income-property financing. It can also be unpermitted, in violation of local rules, or a liability in disguise. This section helps buyers tell the difference.
