Basic ADU Regulations in Chula Vista

Our guide on Chula Vista ADU regulations provides detailed information about the building requirements for different types of ADUs. Read below to get all the necessary information.

In Chula Vista, properties designated for both single-family and multi-family purposes might meet the criteria necessary for the construction of Accessory Dwelling Units (ADUs).

It is essential to consult the specific ADU zoning regulations applicable to your jurisdiction to ensure compliance. ADU zoning regulations typically address factors such as ADU size, setback requirements, height specifications, and other relevant guidelines. By understanding and adhering to the appropriate zoning regulations, property owners can determine the feasibility and eligibility of constructing ADUs on their designated properties, promoting informed decision-making in the pursuit of additional dwelling unit development.

Number of ADUs allowed in Chula Vista

The number of ADUs you’re able to build depends on how your lot is zoned:
– Properties designated for single-family use are permitted to add one ADU and one JADU.
– In the case of properties zoned for multi-family use, you may include two new detached ADUs and, additionally, at least one conversion ADU. The conversion ADU entails converting the interior of an existing structure, provided that it doesn’t exceed 25% of the original unit count.

ADU Dimensions and Construction Limitations in Chula Vista

Attached accessory dwelling units in Chula Vista cannot be larger than half the total floor area of the primary residence or 850 square feet for a one-bedroom unit, or 1,000 square feet for units with more than one bedroom, whichever is greater. If the accessory dwelling unit is inside an existing accessory structure, it can be expanded by up to 150 square feet beyond the current physical dimensions to allow for entry and exit.

In Chula Vista, the total floor area for a detached accessory dwelling cannot exceed 1,200 square feet.

Attached ADUs can be up to 25 feet high for either a primary single-family or multifamily dwelling, or as high as the underlying zoning designation allows, whichever is lower. The ADU shall also be no greater than two stories.

Detached ADUs can be:

Up to 18 feet on a lot with an existing or proposed single-family or multifamily dwelling if it is located within a half-mile of transit or high-quality transit corridor. The maximum can also be increased to 20 feet only if it is necessary to match the roof pitch of the ADU to that of the main house.
Up to 18 feet on a lot with an existing or proposed multi-story multifamily dwelling, regardless of proximity to public transit.

Consistency in exterior features, including roofing, trim, walls, windows, and color palette, between the ADU and the primary dwelling unit is required. 

ADU Setbacks Requirements in Chula Vista

A new attached accessory dwelling unit is allowed a setback of no less than four feet from the side and rear lot lines.

A new detached accessory dwelling unit is allowed a setback of no less than four feet from the side and rear lot lines and shall be located a minimum of six feet from a primary residence.

Parking Requirements for ADUs in Chula Vista

For an ADU, a single parking space can be designated. This parking space can be situated within the setback areas or integrated into an existing driveway as tandem parking. If parking spaces are removed to construct an ADU or transformed into one, they do not need to be replaced.

An ADU does not require a parking space if:

It is situated within a one-half-mile radius of public transportation or within one block of a car-share location.
It is located in an architecturally and historically significant district.
It is part of the existing primary residence or an accessory structure.
It is situated within one block of a car-share vehicle.
It is in an area where on-street parking permits are mandated but not made available to the occupant of the ADU.

ADU Occupancy Requirements in Chula Vista

Cities don’t require owner occupancy until 2025. However, should a property have both an ADU and JADU, JADU law requires owner-occupancy of either the newly created JADU, or the single-family residence.

ADUs shall only be rented for a term of at least 30 days.
