An Accessory Dwelling Unit (ADU) is a self-contained living unit that is secondary to the main dwelling on a residential property. Also known as "granny flats," "in-law units," or "secondary units," ADUs provide additional housing options within existing neighborhoods. These units can be either attached to the primary residence, such as a converted garage or basement, or detached from it, like a standalone cottage or apartment.
ADUs offer numerous benefits, both for homeowners and the community as a whole. They provide an opportunity to increase the housing supply, accommodate multigenerational households, generate rental income, and create more affordable housing options within desirable neighborhoods. ADUs can contribute to the diversity and vibrancy of communities while preserving the character and scale of existing neighborhoods.
It's important to note that ADUs are subject to specific regulations and requirements set by local municipalities, including the City of San Diego. These regulations aim to ensure that ADUs are built in compliance with safety standards, zoning restrictions, and other considerations to maintain the integrity of the community.

It is essential to understand these requirements to ensure compliance and a smooth ADU construction process. In this section, we will explore the permissible locations for ADUs, size and height restrictions, as well as parking and setback requirements set forth by the City of San Diego.
The City of San Diego allows ADUs in various residential zones, including single-family zones, multifamily zones, and mixed-use zones. However, it's important to note that specific regulations may vary depending on the zone in which the property is located. Homeowners and contractors should refer to the San Diego Municipal Code or consult with the city's planning department to determine the zoning regulations for their specific property.
San Diego has established size limits for ADUs to ensure compatibility with the existing housing stock and maintain the character of neighborhoods. The maximum size of an ADU is typically determined by a percentage of the primary dwelling's square footage or a specific limit, whichever is less. It is essential to consult the city's zoning regulations to determine the specific size restrictions applicable to your property.
In terms of height restrictions, ADUs must comply with the height limits set forth in the San Diego Municipal Code. The height of the ADU is typically measured from the natural grade at the location of the unit. It is crucial to review the specific height limitations for your property to ensure compliance.
Parking requirements for ADUs in San Diego are influenced by factors such as the proximity to transit, lot size, and whether the ADU is located within a historic district. In general, the City of San Diego has relaxed parking requirements for ADUs to encourage their development. However, it is important to review the specific parking requirements applicable to your property to ensure compliance.
Setback requirements refer to the distance between the ADU and the property lines or other structures on the property. The City of San Diego has specific setback regulations to ensure adequate spacing between buildings and maintain privacy and safety. It is crucial to review the setback requirements for your property to ensure compliance during the ADU construction process.
