What is an Accessory Dwelling Unit (ADU)? 

Accessory Dwelling Units (ADUs) are defined as complete independent dwelling units that have permanent provisions for living, sleeping, eating, cooking, and sanitation located on the same property as a single-family home. ADUs are also known as second dwelling units, in-law units, granny flats, and/or mother-in-law quarters. ADUs may either be attached or detached from the primary home and/or include a conversion of existing legal space on the property. 

What is a Junior Accessory Dwelling Unit (JADU)?

Junior Accessory Dwelling Units (JADUs) are semi-independent dwelling units no larger than 500 square-feet within a portion of an existing single-family home such as a garage, great room, home office, etc. JADUs include a bedroom, a food preparation area and storage cabinets, and may include a separate bathroom. JADUs also require a separate exterior entrance and a potential internal connection with the remainder of the home.

Why are ADUs/ JADUs important to Woodland? 

ADUs/ JADUs provide housing opportunities in a flexible manner to address the unmet demand for affordable housing for the Woodland Community, including but not limited to, students, young professionals, small families, disabled individuals, senior citizens, etc. while also assisting homeowners to offset the cost of homeownership and maintenance, by renting out ADUs as an additional source of income.
