An attached ADU may be two stories in Baldwin Park. However, due to height restrictions you cannot build a two-story ADU in Baldwin Park.

No, stacked ADUs (one ADU on each floor of a two-story structure) are not allowed in Baldwin Park.

No, two ADUs attached together are not allowed in Baldwin Park.

No, a JADU is defined as an ADU converted from existing space within the main structure of the primary dwelling unit. As such, it cannot be attached to an ADU.

Roof decks are not prohibited for ADUs in Baldwin Park. However, California building safety codes about roof deck safety railings apply, and the height of the railing applies to the total height of the building, so the whole structure including the railings must comply with ADU height requirements. California requires that deck rails be 36 inches high on residential dwellings, 42 inches high on multifamily dwellings.

The exterior of the ADU must align with the architectural and aesthetic style of the rest of the neighborhood, using similar materials and design elements to maintain consistency with the main dwelling unit and surrounding dwellings (similar to a garage conversion).

While not setting a percentage, Baldwin Park requires that property maintain “sufficient” open and permeable space on the lot. 

The plan check requires a review by the Planning Department and the Department of Building & Safety for zoning, building standards, and safety compliance. The process takes approximately 4-6 weeks.

Parking for Baldwin Park ADU

Baldwin Park typically requires one additional parking spot per ADU be added to the property. However, if the property is located within a half-mile of a public transit stop, it may be exempt from this requirement. ADUs converted from an existing garage or carport are also exempt from this parking requirement.

If a parking space must be added, it can be included on the driveway or configured as tandem parking for ADU construction.

Additional City of Baldwin Park ADU Regulation Resources

Per Title 24 of the California Energy Code, solar panels of appropriate size and capacity are mandatory on new-construction ADUs. ADUs built from converted existing structures are exempt, as may be ADUs located under significant shading. Smaller ADUs may be subject to reduced or modified solar panel requirements.

An ADU is not required to have a separate water or electrical meter. You can opt for the ADU to share service with the main dwelling unit. However, you can request separate water or electrical meters from the City of Baldwin Park.

Baldwin Park does not automatically assign a new ADU its own address. However, it may assign the ADU a new address if it is intended for rental or independent occupancy. The ADU will usually get a “½” designation — for example, an ADU located behind 1234 Pine Street would have the address “1234½ Pine Street.”

Low Impact Development (LID) is an approach to land development or redevelopment that seeks to preserve and conserve onsite water quality and natural features, with minimal detrimental effect to local waterways and ecosystems. Baldwin Park may require LID fees for larger ADUs.

Per the Costa-Hawkins Act of 1995, Baldwin Park does not impose rent control on dwellings constructed after February 1, 1995. This means most new-build ADUs are exempt. However, if the primary dwelling unit is subject to rent control, it might apply to the ADU as well.

While encouraging the use of electric appliances for efficiency and sustainability, Baldwin Park does not prohibit gas appliances in new ADUs.

In Baldwin Park you are only required to install sprinklers in new ADU plans if the primary dwelling unit has them as well. You may also be required to install them if the ADU is located within a special fire hazard zone.
