Chula Vista has updated its ADU ordinance to comply with new state laws. Below are the up-to-date requirements for permitting an ADU in Chula Vista
Updated Jul 27, 2022
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.
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.)
