La Jolla ADU Regulatory Overview

La Jolla’s ADU regulations, as part of the City of San Diego, encompass a range of zoning laws, design criteria, and building standards. These regulations are designed to accommodate the growing demand for housing while maintaining the character and livability of neighborhoods. Unique aspects include allowances for both detached and attached ADUs, the integration of Junior ADUs (JADUs), and specific conditions under which additional ADUs may be permitted on a single-family lot, especially under affordable housing schemes.

La Jolla ADU Permitting Process

The ADU permitting process in La Jolla involves the following:

  • Preparation

Gathering all necessary documents, including site plans, architectural designs, and utility plans.

  • Submission

Digital submission of applications and supporting documents through the City of San Diego’s online portal.

  • Review

The city reviews the application against zoning, building codes, and other local regulations.

ADU Building Codes in La Jolla

ADUs up to 16 feet in height have a zero-foot setback requirement from side and rear property lines. For ADUs exceeding 16 feet in height or comprising two stories, a minimum 4-foot setback from side and rear lines is mandated.

Detached ADUs need to maintain a minimum distance of 6 feet from other existing structures to ensure safety and privacy.

The City of San Diego accepts digital submissions for ADU applications, streamlining the permitting process.

A Building Verification Survey may be required based on the ADU’s proximity to property boundaries or as determined by the inspecting official, especially in situations where site conditions are complex.

Properties located within the Coastal Overlay Zone may need a Coastal Development Permit, depending on the ADU’s impact on coastal resources and compliance with the California Coastal Act.

Soil reports might be mandated for properties with specific geological concerns, such as those on steep slopes or in areas known for soil instability, to ensure the structure’s safety and stability.

ADU Zoning in La Jolla

Single-family lots in La Jolla can accommodate up to two ADUs, which includes one standard ADU and one Junior ADU (JADU). Additional units may be possible under specific conditions, such as affordability criteria or location within transit priority areas.

Multifamily properties are permitted to build two detached ADUs and convert existing non-habitable spaces into additional ADUs. The City of San Diego’s regulations provide significant flexibility for increasing housing through these conversions.

Detached ADUs can be as large as 1,200 square feet, regardless of the primary dwelling’s size.

Attached ADUs must not exceed 50% of the primary dwelling’s living area, with a maximum allowed size of 1,200 square feet.

ADUs must match the primary residence in terms of architectural style, materials, and access. They are required to have an exterior entrance separate from the main house and comply with local design guidelines.

The placement of ADUs must follow local setback regulations. They can be attached, detached, or converted from existing spaces within the property, with the specific location depending on the layout of the property and compliance with zoning rules.

Finalizing Your ADU in La Jolla

The submission and verification process for ADU development in La Jolla requires careful consideration of parking arrangements, usage parameters, and utilities connection. Parking requirements include one space per ADU, with exemptions under specific conditions. ADUs can be rented out, providing a valuable source of income, but must adhere to local rental regulations. Utilities for ADUs can typically be connected to the existing services of the primary residence, streamlining the development process.
