Garden Grove ADU Conversion Requirements

An entertaining conversation about how Garden Grove ADU Conversions work!

Benefits of ADUs:

The City of Garden Grove highlights the following advantages of ADUs:

• Affordability: ADUs are generally more affordable to construct than traditional homes due to not requiring land acquisition, extensive new infrastructure, or structured parking.
• Income Generation: Homeowners can generate rental income by leasing out their ADUs.
• Cost-Effective Construction: Built primarily with wood frame construction, ADUs are significantly less expensive than units within new multi-family buildings.
• Diverse Housing Options: ADUs cater to various housing needs, offering spacious living arrangements suitable for couples, small families, friends, young professionals, seniors, and multigenerational families.
• Increased Housing Supply: ADUs contribute to addressing California's housing shortage.
• Proximity to Amenities: ADUs offer residents proximity to jobs, amenities, and schools.
• Aging in Place: ADUs allow seniors to age in place by providing independent living spaces while remaining close to family for support.

Types of ADUs:

• New Construction: A detached ADU can be built on a property with an existing single-family home or as part of a multi-family development.
• Conversion: Existing spaces within a single-family home, attached structures (like garages), or portions of multi-family dwellings can be converted into ADUs.
• Junior ADUs (JADUs): JADUs are smaller units (up to 500 sq ft) contained entirely within the existing structure of a single-family home, often converted from a portion of the living space or attached garage.
