Converting a Garage, Basement, or Attic
Converting a garage or basement is often ideal for an in-law suite since it already has framing and foundation. Expect to spend $20,000 to $60,000 to convert a garage and $10,000 to $30,000 to finish a basement.

ADU stands for Accessory Dwelling Unit, sometimes called granny flats or mother-in-law apartments. The most common ADUs are smaller housing units built on the same site as a single-family home by converting existing structures (like a garage) or building new in the back yard.

An accessory dwelling unit, or ADU, is a unit with a full kitchen and bathroom that is accessory to residential. Also called a granny flat or second unit, it can be on a property with a home or apartment building. It can also be detached or attached.

If you're looking to finance a mother-in-law suite, there are several options you can explore, such as home equity loans, cash-out refinancing, construction loans or manufacturer financing.
In-Law Suite
Converting a garage into a full in-law or guest suite—or a guest house in the case of a detached garage—costs $20,000 to $50,000 on average. At the lower end of the range, a basic conversion will include insulation, drywall, flooring, and a bathroom.
If you know the unit will sit vacant for a while, an in-law unit can be turned into a more traditional rental, with long-term monthly or even yearly leases.
Approximately 500 to 700 square feet is a good size for an in-law apartment or addition.
A new bathroom could help your home increase in value, as well as providing a little peace and quiet for those more private moments. Typically, bathrooms have the potential to add between 4-5% onto your home's value.
Terms such as “master bedroom,” “mother-in- law suite,” and “bachelor apartment” are commonly used as physical descriptions of housing units and do not violate the law.
