Accessory Dwelling Units (ADUs) are a widespread topic in city planning and housing policy, especially in San Diego. These Accessory Dwelling Units, often known as granny residences, in-law suites, or secondary devices, offer a solution to the housing disaster by way of increasing the provision of inexpensive housing within present neighborhoods. San Diego, like many different cities in California, has implemented legal guidelines and policies to facilitate the development of ADUs. This article explores the current legal framework governing ADUs in San Diego, the advantages and demanding situations related to them, and the future outlook for ADU development within the state.
Historical Context and Legislative Background of ADUs in San Diego
ADU Laws in San Diego
California has been at the forefront of promoting ADUs through state regulation. In 2017, the state exceeded numerous legal guidelines aimed at lowering boundaries to ADU creation. These laws included SB 1069, AB 2299, and AB 2406, which together mandated that nearby governments ease regulations on ADUs, streamline the approval method, and decrease fees. Subsequent rules in 2019, together with AB 68, AB 881, and SB 13, similarly relaxed rules, taking into account extra ADUs in step with the lots, eliminating owner-occupancy requirements, and decreasing or putting off effect expenses for smaller settings.
In 2023, AB 1033 was passed which removed the state-level restriction on selling ADUs separately. The law authorizes local agencies to adopt ordinances allowing ADUs to be sold as condos separately from the main residence with approval from the California Department of Real Estate.
Local Implementation of ADUs in San Diego
San Diego has embraced these mandates and gone further to encourage ADU development. The town’s ADU regulations are designed to align with legal guidelines whilst addressing nearby housing desires. San Diego’s Municipal Code defines ADUs as secondary dwelling units that provide entire independent living facilities for one or more individuals and are placed on the same parcel as a single-family or multi-family housing unit.
San Diego's ADU Regulations
Definition and Types of ADUs
San Diego’s Municipal Code defines ADUs as secondary dwelling units that provide entire independent living facilities for one or more individuals and are placed on the same parcel as a single-family or multi-family housing unit. ADUs can be attached to the primary dwelling, detached, or converted from existing structures which includes garages.
There are three types of ADUs in San Diego:
- Detached ADUs: Stand-alone units are split from the primary dwelling unit.
- Attached ADUs: Units that are attached to the primary residence and share a wall.
- Junior ADUs (JADUs): Smaller units, up to 500 sq. ft. made from existing space within the primary dwelling unit.
Permission and Approval Process
San Diego has streamlined the permission process for ADUs to conform with state regulations. Critical elements of the process include:
- Ministerial Approval: ADU applications must undergo ministerial approval, meaning they do not require discretionary assessment or public hearings. This considerably fastens the approval timeline.
- Building Permits: Applicants should gain building permits, which involve submitting plans that conform with building and safety codes.
- Fee Reductions: San Diego has reduced impact costs for ADUs and removed them altogether for units under 750 sq. ft. This makes ADU construction more affordable for homeowners.
Development Standards for ADUs in San Diego
San Diego has devised well-designed development standards to ensure that ADUs are compatible with existing neighborhoods. These standards cover the following aspects:
- Size: Detached ADUs can be up to 1,200 sq. ft. while attached ADUs are restricted to 50% of the primary residence’s square footage. JADUs are constrained to 500 square feet.
- Setbacks: This is a distance through which a structure or part of a structure is set back from the property line.ADUs have to meet certain setback requirements, usually 4 feet from the side and rear of the property.
- Height: Detached ADUs are usually limited to a top of 16 feet, although some flexibility exists for two-story ADUs relying on the lot size and area. This incorporates an additional 2 feet to incorporate a roof pitch that is aligned with the main residence (for two-story ADUs).
- Parking: Parking necessities for ADUs have been relaxed extensively. No extra parking is required if the ADU is within half of a mile of public transit, in a historic district, part of an existing primary residence, or positioned in a neighborhood with on-street parking permits where the permits aren’t required for the ADU occupants.

Benefits of ADUs
ADUs offer several benefits:
Addressing Housing Shortages
San Diego, like many urban areas in California, faces a sizeable housing scarcity. ADUs provide a practical solution by means of presenting additional housing within existing neighborhoods without the need for new infrastructure. This allows the proliferation of general housing and might make housing more affordable for the average homeowner.
Promoting Affordable Housing
ADUs could offer a supply of fairly affordable housing. Because these are typically smaller and less expensive to construct than conventional single-family homes, they can be rented at lower rates. This makes them an attractive choice for college kids, young professionals, and aged individuals.

ADUs offer opportunities for multigenerational dwelling, allowing households to live close together while preserving separate dwelling spaces. This may be specifically useful for families with aged parents or younger grown-up children who desire affordable housing alternatives.
Enhancing Property Values
For homeowners, building an ADU can increase property values by adding to the living space, thereby generating rental potential. This can be a substantial economic incentive for house owners to spend money on ADU production.
Challenges and Criticisms with ADUs in San Diego
In the past, the concept of ADUs has also faced several setbacks and criticisms:
Neighborhood Opposition
Despite the benefits, ADUs can face opposition from residents concerned about population density, parking shortages, and adjustments to neighborhood. These worries can sometimes lead to resistance towards ADU development, despite streamlined approval and processes.
Cost and Financing
While ADUs are typically much less expensive to build than new homes, the development expenses can nevertheless be extensive. Financing an ADU may be a barrier for a few homeowners, in particular, those with limited equity in their primary residence. While there are mortgage packages to be had, navigating the financial process can be complicated.
Regulatory Complexity
Even with streamlined approaches, navigating the various building codes, zoning rules, and permit requirements may be daunting for homeowners. Ensuring compliance with all guidelines calls for cautious planning and, in a few cases, expert assistance, which could add to the overall value.
Impact on Infrastructure
Increased density from ADUs can stress the existing infrastructure, along with water, sewer, and road structures. While ADUs usually have a smaller impact than multi-family developments, towns want to devise for and manage these incremental changes in public services and infrastructure.
Future Outlook for ADUs in San Diego
Although ADUs have witnessed their fair share of infamy, they have been welcomed by homeowners and endorsed by legislative support.
Continued Legislative Support
Endorsing ADUs through legal channels is likely to be maintained. California’s housing crisis remains a crucial problem, and ADUs are seen as an integral part of the answer. Future legislation may additionally loosen up regulations or provide extra incentives for ADU construction.
Technological and Design Innovations
Innovations in construction and design are making it less difficult and cost-effective to build ADUs. Prefabricated and modular ADUs, for example, can significantly reduce construction time and associated costs. These improvements could make ADUs an excellent alternative for homeowners.
Increased Awareness and Acceptance
As more ADUs are built and their benefits become more apparent, public cognizance and attractiveness are likely to grow. Successful ADU initiatives can serve as examples for other homeowners and communities, assisting to triumph over competition and inspire further adoption.
Financial Incentives and Assistance
To cope with the financial barriers to ADU creation, additional programs supplying economic incentives and assistance are in all likelihood to emerge. This may want to consist of low-interest loans, offers, or tax incentives aimed toward lowering the upfront expenses for owners inquisitive about constructing ADUs.
Integration with Broader Housing Policies
ADUs will possibly remain integrated into broader housing regulations aimed at increasing density, promoting low-cost housing, and growing greater sustainable urban environments. This holistic technique can help make certain that ADU improvement contributes positively to universal housing goals.
Conclusion
San Diego’s approach to ADUs represents a forward-thinking attempt to cope with housing shortages and promote inexpensive housing through revolutionary city plans and supportive legislation. While challenges continue to be, the blessings of ADUs—ranging from increased housing delivery and affordability to more desirable assets incorporating real estate values and multigenerational living make them a valuable factor of San Diego’s housing approach.
