Introduction
Accessory Dwelling Units (ADUs) are a practical and increasingly popular solution to expand housing options in Del Mar. These smaller, independent residential units are located on the same lot as a single-family home and come in three forms: internal ADUs (converted portions of existing homes), attached ADUs (additions to homes), and detached ADUs (new stand-alone structures). ADUs are often referred to as accessory apartments, secondary suites, or granny flats.
Proteus Homes specializes in building ADUs that enhance your property value while simplifying the construction process. As a trusted custom home builder, Proteus Homes uses a proprietary system to deliver ADUs on time and on budget, providing efficient and beautifully designed spaces tailored to your needs.
What are Accessory Dwelling Units?
ADUs are secondary living spaces on the same lot as a primary residence. They offer numerous benefits, including:
- Affordable Housing: A cost-effective option for expanding living spaces or generating rental income.
- Multigenerational Living: Ideal for accommodating extended family members.
- Enhanced Property Value: Boosts the usability and market appeal of your property.
In Del Mar, ADUs also support the city’s housing goals while preserving its unique community character.
ADU Regulations in Del Mar
Size and Building Constraints
Del Mar permits detached ADUs up to 850 square feet for units with one bedroom and up to 1,000 square feet for units with two or more bedrooms. ADUs up to 800 square feet are exempt from lot coverage requirements, allowing homeowners flexibility in maximizing their property’s potential.
Setback Requirements
ADUs must have a minimum of 4 feet of setback from rear and side property lines. Front yard setbacks must comply with zoning standards. For ADUs taller than 16 feet, the setbacks of the underlying zoning regulations apply. Additionally, properties in designated coastal or beach overlay zones must adhere to stricter setback requirements to protect scenic views and natural resources.
How many ADUs can you build on your property in Del Mar?
-
Single-Family Lots: Homeowners can build one ADU (attached or detached) and one Junior ADU (JADU). JADUs must be created from existing space within the primary residence and are subject to owner occupancy requirements.
- Multifamily Lots: Up to two detached ADUs are allowed. In addition, non-livable spaces, such as storage rooms or garages, within existing multifamily structures can be converted to ADUs, up to 25% of the total existing units.
Design and Construction Considerations
Can You Build a 2-Story ADU in Del Mar?
Yes, but any ADU exceeding 16 feet in height must comply with the setbacks of the underlying zoning. This allows for 2-story designs that adhere to local regulations while maximizing vertical space.
Can you convert a garage into an ADU or add an ADU on top of a garage in Del Mar?
Yes, garages and other existing non-livable spaces can be converted into ADUs. Additionally, adding an ADU on top of a garage is possible, subject to setback and height requirements. Effective January 2025, no replacement parking is required for garages converted into ADUs.
What are the parking requirements for ADUs in Del Mar?
No parking space is required for an ADU if:
- The unit is within 0.5 miles of public transit.
- The property is in a historic district.
- The ADU is converted from an existing structure or is attached to the primary residence.
What is the average time of the permitting process in Del Mar?
State law mandates a streamlined, ministerial review process. Complete applications are approved within 60 days. Applicants need to submit an ADU application packet, pay fees, and provide development plan sets.
