Basic ADU Regulations in Downey

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

In Downey, 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 Downey

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 attached ADU or one detached with one JADU.
– In the case of properties zoned for multi-family use, you may include two new detached ADUs.

ADU Dimensions and Construction Limitations in Downey

Attached accessory dwelling units in Downey can be 850 square feet for a one-bedroom unit, or 1,000 square feet for units with more than one bedroom, whichever is greater.

Detached accessory dwelling units in Downey can be 850 square feet for a one-bedroom unit, or 1,000 square feet for units with more than one bedroom, whichever is greater.

if attached to the primary dwelling unit, an ADU in Downey may go up to a height of 25-feet.

The maximum height for detached accessory dwelling units shall be 16 feet.

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 Downey

Attached ADUs shall maintain a minimum four-foot setback from rear and side-yard property line. Front yard setback and required building separation requirements are per applicable zoning standards and building code standards, respectively.

Detached ADUs shall maintain a minimum four-foot setback from rear and side-yard property line. Front yard setback and required building separation requirements are per applicable zoning standards and building code standards, respectively.

Parking Requirements for ADUs in Downey

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 Downey

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.
