What is an ADU?

An ADU, often called a granny flat or casita, is a self-contained residential unit added to a single-family lot, either as a detached structure or attached to the primary dwelling. Junior ADUs (JADUs) are smaller rental units, up to 500 sq ft, created within existing house walls. They require owner occupancy on the property.

Del Mar ADU Rules and Regulations

While California legislation sets baseline ADU allowances that local jurisdictions must follow, cities can adapt regulations to their communities. Here are key considerations from Del Mar’s draft ADU ordinances that homeowners should understand:

adu laws in del mar rules and regulations

Where ADUs Are Allowed

  • Residentially zoned parcels with existing or proposed housing
  • Commercial/mixed-use zones with residential uses

Permissible Zones for ADUs and Jr. ADUs

ADUs are sanctioned in zones that permit the development of single-dwelling units or multiple-dwelling units. In Del Mar, this encompasses all residential zones within the city and the Carmel Valley Precise Plan Specific Plan (CVPP).

  • For a lot with a single dwelling unit, a maximum of one ADU and one JrADU is allowed. The JrADU must be situated within the walls of the primary dwelling unit. In addition to the JrADU, one detached ADU is permitted, either within a new detached structure or within an existing detached accessory structure converted to an ADU. Alternatively, a single dwelling unit lot is allowed to have either one ADU within the walls of the primary single dwelling unit or create one attached ADU within an addition to the primary single dwelling unit. However, in these two scenarios, a JrADU would not be permitted. JrADUs are not allowed within a detached ADU, and a maximum total of one ADU is allowed under all circumstances. The primary dwelling unit in all scenarios can be an existing or proposed structure.
  • An existing duplex (two units on one lot, attached or unattached) is allowed to have a maximum of two ADUs per lot. The primary dwelling units must exist. Each primary dwelling unit can have one ADU that is detached or attached to the primary dwelling unit, adhering to the development standards applicable to ADUs on lots with a single dwelling unit. If necessary to safeguard coastal access and coastal resources, such ADUs may be accommodated in a design where one or both of the ADUs are attached to their respective primary dwelling units; however, the ADUs cannot be attached to each other. The city’s Coastal Development Permit findings may be employed in this case to justify the accommodation of attached ADUs in this scenario.
  • A lot with an existing multiple dwelling unit development that includes three or more dwelling units (i.e., RM-South) is allowed to integrate ADUs into spaces not located within the dwelling units themselves. This type of ADU may be constructed within existing multiple dwelling unit building spaces not associated with an individual dwelling unit (i.e., common area storage rooms, boiler rooms, attics, basements, or parking garages). The maximum number of ADUs in the converted space of multi-dwelling unit buildings is 25 percent of the total number of existing dwelling units on the lot. Additionally, up to two more ADUs may be situated on multiple dwelling unit lots as detached structures (a maximum of two detached ADUs per lot).
  • JrADUs are permitted only in single dwelling unit zones, which, within the City of Del Mar, include the CVPP, R1-10, R1-10B, R1-14, R1-40, R1-5, and R1-5B zones. Only one JrADU is allowed per lot.

 

Number of ADUs Allowed

ADU Type Allowances in Del Mar
JADU One per single-family home with owner occupancy
Detached ADU One per single-family home
Attached ADU One per single-family home
Multifamily ADUs Convert up to 25% of existing units

So a single-family home could have a detached ADU plus a JADU. Multifamily properties may incorporate ADUs through conversions or new structures.

ADU Development Standards

Del Mar’s draft ADU ordinances contain allowances for:

  • Reduced setbacks: 4 feet rather than 5+ ft
  • Detached ADU height: up to 16–25 feet for 2 stories
  • Limitations on parking requirements

The draft rules also outline protections for environmental resources, scenic views, and community character.
