ACCESSORY DWELLING UNITS (ADU)

An ADU is an attached or detached residential dwelling unit, on the same lot as an existing single-family or multi-family dwelling unit which is zoned for single-family, multifamily or mixed use that provides complete independent living facilities for one or more persons. This includes permanent provisions for living, sleeping, eating, cooking, and sanitation, all on the same parcel as the primary, single-family dwelling and multi-family dwellings. An ADU can be an efficiency unit, as defined in Section 17958.1 of Health and Safety Code, or a manufactured home, as defined in Section 18007 of the Health and Safety Code. 

 A junior accessory dwelling unit (JADU) is a residential dwelling unit that is no more than 500 square feet in area, contained entirely within an existing area or proposed area within a single-family residence, contains only an efficiency kitchen, and can have separate sanitation facilities or shared sanitation facilities with, the existing single-family residence. A junior accessory dwelling unit is not permitted within multi-family dwelling units. 

ADUs and JADUs provide housing opportunities within existing neighborhoods creating housing that is already connected to the local character and infrastructure. The additional units help diversify the market for renters while providing supplemental income for homeowners, and thus increasing affordability throughout Lemon Grove. 

PREAPROVED ADU PLANS

Assembly Bill 1332 (Government Code Section 65852.27) requires local agencies to develop a program to preapprove architectural and design plans for ADU’s by January 1, 2025. Major provisions include:

• Develop a preapproval program for ADU’s
• Streamlined 30-day approval for preapproved plans. 

Anyone interested in providing preapproved ADU plans must submit ADU plans that are not site-specific and include architectural plans and structural drawings and calculations to the Lemon Grove Building Department for review and approval.

Preapproved ADU plans and a site-specific plan must be submitted as part of an ADU permit application. The project description should identify that it is a preapproved ADU design with the specific plan preparer identified.

To date, no preapproved ADU plans have been approved for use.
