ADU House Plans

An A.D.U. house plan refers to an Accessory Dwelling Unit (ADU), which is a secondary housing unit on the same property as a primary residence. ADUs are also known by various other names such as granny flats, in-law suites, secondary suites, carriage houses, garden suites, or backyard cottages. These units are fully equipped with their own kitchen, bathroom, and sleeping facilities, providing a separate living space from the main dwelling.

ADUs can take different forms, including converted garages, basement apartments, separate structures in the backyard, or additions to the main house. They offer a way to create additional housing options within existing neighborhoods, helping to address housing shortages and provide more affordable housing solutions and provide an extra source of income for the property owner.

The regulations and zoning requirements for ADUs vary by location, and not all areas permit or regulate them in the same way. Many places have zoning laws governing ADU construction, including size restrictions, setback requirements, and occupancy regulations. If you’re considering building an ADU, it’s important to check the local regulations in your area.
