What is an ADU?

Definition and Purpose of an ADU

Before delving into the intricacies of ADU building codes, it is essential to have a clear understanding of what an ADU actually is. ADU stands for “Accessory Dwelling Unit,” which is a term used to describe a secondary housing unit that is built on the same lot as a primary residential property. Also known as “granny flats,” “in-law suites,” or “backyard cottages,” ADUs have gained significant popularity in recent years due to their potential to address housing shortages, provide additional rental income, and accommodate multi-generational living arrangements.

The purpose of an ADU is to create a self-contained living space that is separate from the main dwelling. These units can vary in size and design, ranging from converted garages or basements to purpose-built structures. ADUs are commonly used as rental properties, providing homeowners with an opportunity to generate extra income. Additionally, ADUs can serve as living spaces for family members, such as aging parents or adult children, allowing for privacy and independence while still maintaining proximity to the main residence.

The flexibility and versatility of ADUs make them an attractive option for homeowners looking to maximize the potential of their property. Whether it’s utilizing unused space, converting an existing structure, or constructing a new building, ADUs offer a range of possibilities that can be tailored to suit individual needs and preferences.

In the next section, we will explore the importance of understanding ADU building codes and how they play a crucial role in the construction and regulation of these auxiliary dwelling units.

Importance of Building Codes for ADUs
