Chula Vista

Chula Vista is a beautiful city in Southern California and one of the best places to build an ADU. The weather is perfect for year-round outdoor activities, the cost of living is relatively low, and there are plenty of resources for building an ADU. Chula Vista is also a great place to raise a family or retire -- both of which are made better with an ADU.

Zoning

All properties zoned for single family and multifamily use may be eligible to build ADUs.

Number of units

The number of ADUs you’re able to build depends on how your lot is zoned:

  • Lots zoned for single family use may add 1 ADU and 1 Jr. ADU (JADU).
  • Lots zoned for multi-family may add 2 new detached ADUs and at least one conversion ADU (interior conversion of existing building, but no more than 25% of the original number of units. (E.g. an apartment with 4 units may add 2 detached ADUs and 1 conversion ADU.)

Building size

  • The maximum size is 500.0 sq. ft. for a JADU
  • 850 sq. ft. or 50% of the main home, whichever is greater. Cannot exceed 1200 sf.sq. ft. max for a detached ADU
  • Attached ADU Max Size: 850 or 50% of the main home, whichever is greater. Cannot exceed 1200 sf.

Building height

Building height for attached and detached ADUs is: 16' or the height limit of underlying zone, whichever is greater

Setbacks

  • Backyard Existing Structure Setback: 6 ft wall to wall
  • Side Yard Existing Structure Setback: 6 ft wall to wall

Parking

Parking requirements for accessory dwelling units shall not exceed one parking space per unit or per bedroom, whichever is less. Parking spaces may be provided in tandem on a driveway; provided, that access to the garage for the primary residence is not obstructed. Off-street parking shall be permitted in setback areas or through tandem parking, unless specific findings are made that parking in setback areas or tandem parking is not feasible based upon specific site or regional topographical or fire and life safety conditions.

Restrictions

  • Owner occupancy not required
  • No short term rentals (<30 days)
  • No sale of the ADU separate from the main home
