An "ADU Open House" is an event where an Accessory Dwelling Unit (ADU) is showcased to the public. These open houses allow potential homeowners and interested parties to tour completed ADUs, understand various design and layout options, and learn about the benefits of ADUs, such as increasing property value or providing flexible living solutions. It's a valuable opportunity to connect with builders, designers, and real estate professionals to gather information on the entire ADU development process, from permits to financing.
