Introduction

A junior ADU San Diego property can offer you more livable space in your home. JADUs are becoming increasingly popular in San Diego as a way to provide affordable housing for families, create rental income, or accommodate aging parents. But building a junior ADU comes with different rules and regulations surrounding it.

Regulation of JADUs in San Diego

You need to understand the legal requirements before constructing a JADU in San Diego. In San Diego, JADUs are regulated by the local zoning ordinances and building codes. The regulations vary depending on the zone and the specific characteristics of the property and include:

  • Setbacks

Setbacks are the minimum distance that a structure must be located from the property line. The setback requirements vary depending on the zone and can range from 0 to 25 feet.

  • Size

The maximum size of a JADU is 1,200 square feet or 50% of the existing primary dwelling, whichever is smaller. The JADU must also have a separate entrance, kitchen, and bathroom.

  • Parking

JADUs are not required to provide additional parking if the primary residence has a garage or a dedicated parking space. However, if the primary residence does not have any parking, then one off-street parking space must be provided for the JADU.

  • Maximum Height

The maximum height for a JADU is 16 feet, and it must comply with the height requirements for the zone in which it is located.
