In recent years, Accessory Dwelling Units (ADUs) have gained significant popularity in San Diego due to their potential to address housing shortages and provide additional income opportunities for homeowners. However, navigating the complex web of regulations and laws surrounding ADUs in San Diego can be daunting. Understanding San Diego ADU laws is crucial for anyone considering building an ADU on their property. In this blog post, we will delve into the different types of ADUs in San Diego, explore the city's specific laws and regulations governing ADUs, and provide insights into the permitting process. By the end of this post, you will have a comprehensive understanding of how to successfully navigate the intricacies of San Diego's ADU laws and regulations.
ADUs, or Accessory Dwelling Units, are secondary housing units that can be built on the same property as an existing primary residence. They are also commonly known as granny flats, in-law suites, or backyard cottages. ADUs have become increasingly important in addressing housing shortages and providing affordable housing options in San Diego.
The importance of ADUs in San Diego cannot be overstated. The city has experienced a growing population and limited housing supply, resulting in increased housing costs and a lack of affordable options. ADUs offer a solution by allowing homeowners to create additional housing units on their properties, which can be rented out to tenants or used to accommodate family members.
ADUs provide several benefits for homeowners and the community as a whole. For homeowners, they offer an opportunity to generate rental income, increase property value, and provide housing options for extended family members. ADUs also contribute to the overall housing supply in San Diego, helping to alleviate the housing crisis and potentially reducing rent prices.
Additionally, ADUs promote sustainable living by utilizing existing infrastructure and minimizing the need for new construction. They can be designed to be energy-efficient and environmentally friendly, reducing the carbon footprint of the city.
Understanding the importance of ADUs in San Diego sets the stage for exploring the different types of ADUs available in the city and the specific regulations surrounding their construction and use. Whether you are a homeowner considering building an ADU or a potential tenant seeking affordable housing options, a comprehensive understanding of San Diego's ADU laws is essential. In the following sections, we will delve deeper into the various types of ADUs in San Diego and the specific regulations governing their construction and use.
San Diego offers various types of ADUs to accommodate different needs and property configurations. Understanding the different types will help you determine which option is best suited for your property and desired use. Let's explore the four main types of ADUs available in San Diego:
Detached ADUs are standalone structures that are separate from the primary residence. They can be built as separate units or converted from existing structures such as garages or sheds. Detached ADUs provide complete privacy and independence, making them ideal for homeowners seeking additional rental income or housing options for family members.
Attached ADUs are connected to the primary residence and share at least one wall. They can be built as an extension of the existing home or as a separate unit within the same building envelope. Attached ADUs are a popular choice for homeowners who want to maximize the use of existing space and maintain a closer connection to their main residence.
Junior ADUs, also known as "JADUs," are smaller units that are created within the existing footprint of a single-family home. They typically have their own separate entrance, bathroom, and kitchenette but may share certain utilities with the primary residence. Junior ADUs are an excellent option for homeowners who have limited space or want to create a separate living space for aging parents, adult children, or guests.
Converted existing space ADUs involve converting an existing structure on the property, such as a basement, attic, or bonus room, into a separate living unit. These ADUs are cost-effective options for homeowners as they utilize existing space rather than building new structures. However, it is important to ensure that the converted space meets all the necessary requirements for habitability and safety.
Each type of ADU in San Diego has its own set of regulations and requirements. It is crucial to familiarize yourself with the specific guidelines for the type of ADU you plan to build on your property. By understanding the different types of ADUs available in San Diego, you can choose the option that best suits your needs and complies with local laws and regulations.
San Diego has implemented specific laws and regulations governing the construction, design, and use of ADUs. Understanding these laws is crucial before embarking on an ADU project. In this section, we will explore the key aspects of San Diego's ADU laws and regulations.
San Diego follows the California Building Code (CBC) for ADU construction. The CBC sets standards for structural integrity, fire safety, energy efficiency, and other aspects of building design and construction. ADUs must comply with these requirements to ensure the safety and habitability of the unit.
Zoning laws dictate where ADUs can be built within the city. In San Diego, ADUs are generally allowed in residential zones, subject to certain restrictions. The specific zoning regulations may vary depending on the neighborhood and property type. It is important to consult the San Diego Zoning Code or contact the local planning department to determine the zoning requirements for your property.
San Diego imposes size and height restrictions on ADUs to ensure they are compatible with the surrounding neighborhood. The maximum allowable size and height may vary depending on the type of ADU and the lot size. It is essential to review the specific regulations to ensure compliance with these restrictions.
San Diego has specific parking requirements for ADUs, which aim to minimize the impact on street parking availability. Generally, one off-street parking space is required for each ADU. However, the city has implemented various exceptions and exemptions for certain situations, such as properties located within transit priority areas or near public transportation. Understanding the parking requirements will help you plan for parking spaces when designing your ADU.
Complying with San Diego's ADU laws and regulations is essential to avoid costly penalties and ensure the legality and safety of your ADU project. It is advisable to consult with a professional architect, builder, or ADU specialist who is familiar with the local regulations to ensure compliance throughout the construction process. By understanding the specific laws and regulations in San Diego, you can proceed with your ADU project confidently and in accordance with the city's requirements.
Before starting construction on your ADU project in San Diego, it is important to understand the permitting process. The permitting process ensures that your ADU complies with all relevant laws and regulations and meets the necessary safety standards. In this section, we will guide you through the steps involved in obtaining the required permits for your ADU in San Diego.

They will handle the construction process, coordinate with subcontractors, and ensure that the project is executed according to the approved plans and specifications.

3. Focus on energy efficiency: Design your ADU with energy-efficient features such as insulation, LED lighting, low-flow fixtures, and energy-efficient appliances. This not only reduces utility costs but also contributes to a more sustainable living space.
1. Stay updated on current regulations: San Diego's ADU laws and regulations may evolve over time. Stay informed about any changes to ensure that your ADU remains compliant throughout the construction and occupancy phases.
2. Obtain the necessary permits and inspections: Adhere to the permitting process we discussed earlier, ensuring that all required permits are obtained and inspections are scheduled and completed as required by the San Diego Development Services Department.
3. Comply with building codes and zoning requirements: Ensure that your ADU meets all building code requirements, including structural integrity, fire safety, and accessibility. Also, verify that your ADU complies with the specific zoning regulations for your property.
By following these best practices, you can build a well-designed, functional, and compliant ADU in San Diego.
