However, it is important to note that building an ADU requires understanding the regulations and requirements in place to ensure that the ADU meets all local laws and codes.

Maximum size limitations apply to all adus in San Diego. An ADU typically cannot exceed 1,200 square feet, or 40 percent of the size of the primary residence, whichever is less. Some exceptions may be made for two-story adus, which can be up to 1,500 square feet in size. In addition, any ADU built in conjunction with an existing non-residential use is generally limited to no more than 25 percent of the total floor area of the existing building, or 1,000 square feet, whichever is less.

For example, an ADU must be located at least 5 feet from the side property line and 10 feet from the rear property line.

Before starting your ADU project, you will need to secure permits and have your project inspected to ensure it meets all relevant building codes. Building permits are typically obtained from the local government, such as the City of San Diego. The required permits depend on the scope of your project, and you may need multiple permits from different agencies.
In addition, you may need to hire a licensed contractor, such as an architect or engineer, to certify that your project meets all applicable building codes. Once approved, you will need to schedule inspections with the City of San Diego periodically throughout the project.
