Understanding ADUs: An Overview

An ADU, or Accessory Dwelling Unit, is a self-contained living space that is either attached to or located on the same property as a primary residence. Also known as granny flats, in-law units, or backyard cottages, ADUs provide an additional housing option on residential properties. They can be used for a variety of purposes, such as accommodating family members, renting out for supplemental income, or as a home office or studio.

ADUs come in various forms, including attached ADUs, which are connected to the main dwelling, and detached ADUs, which are separate structures on the same property. They can range in size and layout, from a small studio apartment to a multi-bedroom unit with a full kitchen and bathroom facilities.

The benefits of building an ADU are numerous. For homeowners, an ADU can provide an opportunity to generate rental income, increase property value, and utilize existing space on their property. ADUs also contribute to the overall housing supply, helping to address the housing shortage in high-demand areas like San Diego.

In recent years, the demand for ADUs has grown significantly, prompting many cities, including San Diego, to update their zoning laws and regulations to facilitate their construction. Understanding the basics of ADUs is essential before delving into the specific requirements and considerations for building one in San Diego. In the following sections, we will explore the legal aspects, design considerations, construction process, and financing options to help you navigate the ADU journey in San Diego.
