ADUs are allowed across a broad spectrum of residential zones, accommodating both single-family and multifamily properties with tailored allowances. A key emphasis is placed on ensuring that ADUs aesthetically align with the primary residence, adhering to design criteria that include compatibility in exterior design, materials, and color schemes.

Preliminary Assessment

Verify zoning and property eligibility for ADU construction.

Design and Plan Development

Prepare ADU designs meeting local and state standards.

Document Submission

Submit plans and required documents, preferably digitally, through the city’s online platform.

ADU Local Zoning in Encinitas

Encinitas does not impose a minimum lot size requirement for constructing ADUs, facilitating the development of ADUs across a wide range of property sizes to address housing needs.

In Encinitas, accessory dwelling units that comply with the standard setbacks of the underlying zone can reach the zone’s height limit as per Chapter 30.16.010.B.6 of the Encinitas Municipal Code, allowing for two-story ADUs including those above garages. Additionally, detached ADUs within half a mile of major transit stops or high-quality transit corridors may have 4-foot side and rear setbacks if they are no taller than 18 feet, with an allowance for an additional 2 feet if the ADU’s roof pitch matches the primary dwelling.

Encinitas ADU Building Codes

ADUs can share utilities with the primary residence. Separate metering may be required for high-usage appliances, while connections for water, sewer, electricity, and gas can typically utilize existing services to simplify ADU development.

Building verification surveys are not a required part of the plan review process for ADUs, although they can be helpful to ensure that construction aligns with local zoning and setback requirements.

ADUs must match the primary dwelling in exterior design, including roofing, windows, and color palette, to ensure aesthetic coherence within the property.

Finalizing Your ADU in Encinitas

The development of ADUs in Encinitas involves careful consideration of submission requirements, parking arrangements, and utility connections. Homeowners must submit complete and compliant ADU plans for verification. Parking for ADUs should align with local exemptions and requirements, considering proximity to transit and existing structures. Utilities can often be shared with the primary residence, simplifying the connection process and reducing costs. These considerations are crucial for seamlessly incorporating an ADU into your property, whether for rental income or personal use.
