What value does an in-law suite bring to a home?

The value of having a mother-in-law suite on your property can be immense when built properly. Some homeowners choose to rent out their granny flats as a vacation rental or long-term tenant rental, meaning they receive a quick return on investment (ROI).

How do you build an in-law apartment?

Building an in-law suite can cost a pretty penny. Costs vary on whether a homeowner builds out of an existing space, such as a garage or attic, or whether they build a custom or prefabricated structure separate from the house.

Do you need a permit to build?

Building an in-law apartment is legal in most states but requires a permit. Permits usually cost $1,200 but can reach up to $1,500 depending on if you live on the East Coast, West Coast, or near a big city.
