Long Beach’s zoning screen asks whether the parcel’s applicable district allows residential use and whether a principal dwelling is already present. The City’s Planning Bureau guidance says ADUs and junior ADUs may be allowed in residential districts permitting single-family or multifamily uses, and in mixed-use districts, planned development districts, or specific plans where residential use is allowed.
Check the zone and the underlying land-use designation
The City says an ADU or JADU cannot be added in a zone, planned development, or specific plan that does not allow residential uses merely because a nonconforming residence exists. It identifies an exception when residential use is allowed by the underlying Land Use Element district, or PlaceType. That means a zone label alone may not settle the use question: check the City’s zoning and land-use GIS map, then review the applicable zoning regulations and any PD or SP documents.
Confirm the principal dwelling and local review route
A principal residential use must be present on the lot. Verify its status and the parcel’s current zoning, PlaceType, and plan documents with the City. Once the use screen is satisfied, consult the City’s ADU and California HCD guidance for the applicable state and local development standards. A zoning screen is not a building permit or an approval of a particular design.
