Accessory Dwelling Units (ADUs), also known as granny flats, mother-in-law suites, or secondary suites, are small, self-contained residential units that are located on the same lot as a primary residence. ADUs are typically smaller than the main house and can be either attached or detached from the primary residence.
ADUs can be used for a variety of purposes, such as providing a separate living space for a family member, renting out to tenants for extra income, or as a home office or studio. They are becoming increasingly popular as a way to address the shortage of affordable housing in many cities, as they can provide additional housing options without requiring new land development.
ADUs can come in many different styles and configurations, from converted garages to purpose-built cottages. They usually have their own entrance, kitchen, bathroom, and living space, and can be designed to match the style and aesthetic of the primary residence. In many areas, building an ADU requires a permit and must meet certain building codes and zoning regulations.
