Whether you're a homeowner looking to add an ADU to your property or a developer exploring investment opportunities, this guide will equip you with the knowledge you need to make informed decisions and streamline the ADU building process in San Diego.
An Accessory Dwelling Unit, commonly referred to as an ADU, is a secondary housing unit that can be built on the same lot as a primary residence. ADUs are designed to provide additional housing options, promote affordability, and address the growing demand for housing in urban areas. They offer a versatile solution for homeowners, developers, and communities seeking to maximize the use of existing land and infrastructure.
ADUs come in various forms, including detached units, attached units, and units located within an existing structure, such as a basement or above a garage. They can serve a variety of purposes, such as providing housing for family members, generating rental income, accommodating multigenerational households, or serving as a home office or studio.
The popularity of ADUs has been on the rise due to their numerous benefits. They offer homeowners the opportunity to generate additional income by renting out the unit. ADUs also provide affordable housing options for renters, allowing them to live in desirable neighborhoods without the high costs associated with a traditional single-family home. Moreover, ADUs promote sustainable development by utilizing existing infrastructure and reducing the need for urban sprawl.
To ensure the successful implementation of ADUs, cities and municipalities have established regulations and guidelines governing their construction and use. In the following sections, we will explore the specific rules and regulations related to ADUs in San Diego, shedding light on the requirements and processes involved in building and operating an ADU in this city.
An Accessory Dwelling Unit (ADU) is a secondary housing unit that is located on the same lot as a primary residence. It is a self-contained living space that includes all the essential amenities for independent living, such as a kitchen, bathroom, and sleeping area. ADUs can be either attached to the primary residence, detached as a separate structure, or even located within an existing structure, like a basement or above a garage.
ADUs serve as an additional living space on a property and can be used for a variety of purposes. They provide an opportunity for homeowners to accommodate extended family members, such as aging parents, adult children, or guests. ADUs can also be used as rental units, providing an additional source of income for homeowners.
One of the key features of ADUs is their flexibility and adaptability. They can be designed in various sizes and styles to fit the needs and constraints of the property. ADUs can range from small studio apartments to larger units with multiple bedrooms and living spaces. This versatility allows ADUs to be customized to suit different housing needs and preferences.
The concept of ADUs has gained popularity in recent years due to their potential to address housing shortages, promote sustainable development, and increase housing affordability. By utilizing existing land and infrastructure, ADUs offer a cost-effective solution for expanding housing options without the need for extensive new construction or development.
In the next sections, we will explore the specific regulations and guidelines for building and operating ADUs in San Diego, providing you with a comprehensive understanding of the rules and requirements associated with ADU construction in this city.
San Diego has specific regulations in place that govern the construction and operation of Accessory Dwelling Units (ADUs). These regulations are designed to ensure that ADUs comply with zoning requirements, maintain the character of the neighborhood, and promote safe and sustainable development. In this section, we will explore the key aspects of San Diego's ADU regulations, including size and location restrictions, parking requirements, and owner-occupancy and renting regulations.
San Diego's ADU regulations specify certain size and location restrictions that must be followed when constructing an ADU. The size of an ADU is typically determined by the maximum allowable floor area ratio (FAR) or a percentage of the primary residence's square footage. The exact regulations may vary depending on the zone and lot size of the property. It is important to consult the San Diego Development Services Department or a qualified professional to ensure compliance with these regulations.
Additionally, there may be restrictions on the location of ADUs within the property. For example, setbacks from property lines, height limitations, and other zoning requirements must be taken into consideration when planning the placement of an ADU. These restrictions are in place to ensure that ADUs are compatible with the surrounding neighborhood and do not negatively impact the privacy or livability of neighboring properties.
Parking requirements are an important consideration when building an ADU in San Diego. The city has specific regulations regarding the provision of off-street parking spaces for ADUs. In some cases, additional parking spaces may be required when adding an ADU to a property. However, San Diego has implemented several parking exemption provisions to encourage the development of ADUs, especially in areas with good access to public transportation or where on-street parking is readily available.
It is crucial to understand the parking requirements for ADUs in San Diego and ensure compliance with these regulations. Failure to meet the parking requirements can result in delays in obtaining permits or even the denial of the ADU project.
San Diego's ADU regulations also address the issue of owner-occupancy and renting. Currently, the city allows both the homeowner and tenants to reside in either the primary residence or the ADU. This means that homeowners have the flexibility to rent out both their primary residence and the ADU if desired.
It is important to note that short-term rentals, such as vacation rentals or rentals for less than 30 days, are subject to separate regulations in San Diego. Homeowners must comply with the city's regulations for short-term rentals, which may include obtaining a permit and following specific guidelines.
Understanding the regulations surrounding owner-occupancy and renting is essential when considering the financial aspects and potential rental income associated with an ADU in San Diego.
In the next section, we will explore the process of building an ADU in San Diego, including the necessary permits and approvals, inspection and compliance procedures, as well as estimated costs and potential financing options.

Before embarking on your ADU construction project in San Diego, it is essential to obtain the necessary permits and approvals from the city. The specific permits required may vary depending on the scope of your project, including whether it is a new construction or a conversion of an existing structure. Common permits you may need to acquire include:
1. ADU Building Permit: This permit is required for the construction or conversion of an ADU. It ensures that your project complies with the building codes and regulations set by the city.
2. Electrical, Plumbing, and Mechanical Permits: If your ADU project involves electrical, plumbing, or mechanical work, separate permits may be required for each trade.
3. Grading Permit: If your project involves significant grading or earthwork, a grading permit may be necessary to ensure compliance with erosion control and site stability requirements.
To obtain these permits, you will need to submit detailed plans and documents, pay associated fees, and undergo the necessary inspections. Working with a qualified architect, contractor, or ADU specialist can help streamline the permit application process and ensure compliance with all requirements.
Throughout the construction process, your ADU project will undergo various inspections to ensure compliance with building codes and regulations. Inspections may cover structural elements, electrical systems, plumbing systems, and other components of the ADU. It is important to schedule inspections at the appropriate stages of construction to avoid delays and ensure compliance.
In addition to inspections, you will need to comply with other regulations, such as energy efficiency standards and fire safety requirements. These may involve installing energy-efficient systems, smoke detectors, and fire-rated materials.
Working closely with your contractor and staying in communication with the relevant city departments will help ensure a smooth inspection and compliance process.
The cost of building an ADU in San Diego can vary depending on factors such as the size, design, location, and level of customization. It is important to carefully consider the estimated costs associated with your ADU project before proceeding.
Some of the major cost considerations include:
1. Construction Costs: This includes materials, labor, and other expenses associated with building the ADU.
2. Permit Fees: The city of San Diego charges fees for various permits and inspections, which should be factored into your budget.
3. Utility Connections: If your ADU requires separate utility connections, such as water, electricity, or gas, there may be additional costs associated with these connections.
4. Design and Architectural Services: If you require professional design and architectural services, such as creating detailed plans and renderings, these costs should be considered.
5. Financing Options: Exploring financing options is crucial to ensure that you have the necessary funds to complete your ADU project. This may include personal savings, home equity loans or lines of credit, construction loans, or even ADU-specific financing programs.
By carefully estimating the costs and exploring potential financing options, you can ensure that your ADU project stays within budget and is financially viable.
