What is an ADU ? Accessory Dwelling Unit

ADU stands for Accessory Dwelling Unit, which is a secondary housing unit on a single-family residential lot. It is also known as a granny flat, in-law unit, or backyard cottage. ADUs can be attached or detached from the primary house and can be used as a separate living space for family members, guests, or renters.

ADUs are gaining popularity as a solution to housing shortages and affordability issues in many urban areas. They offer an opportunity to add housing options without changing the character of the neighborhood or adding significant infrastructure. ADUs are typically smaller than the primary residence and can range from 400 to 1,200 square feet. They can include a bedroom, bathroom, living area, and a kitchen or kitchenette.

Types of Additional dwelling units

The type of ADU that is best for a property will depend on the size of the lot, zoning laws, and local building codes. Homeowners should consult with local authorities and a licensed contractor to determine the best type of ADU for their property.

ADUs are an important solution to the housing crisis and offer a range of benefits for individuals, families, and communities. They provide a source of affordable housing, allow homeowners to generate additional income, address environmental concerns, and promote social and intergenerational living. As such, it is important to support policies and initiatives that encourage the construction of ADUs and make it easier for homeowners to build and rent them out. With more ADUs, we can help to address the housing crisis and create more sustainable and livable communities.

the key difference between ADUs and home extensions is that ADUs are standalone structures that are designed to be separate living quarters, while home extensions are additions to the existing home intended to expand living space or add rooms. ADUs can be used for rental income or as housing for family members, while home extensions are primarily for the use of the homeowner.
