D-OM
Downtown Encinitas Specific Plan-Office Mixed Zone
This zone is intended to provide a zoning district that allows individual properties to develop as either residential, office professional, or a mix of both. In a mixed use, residential uses may be allowed on the same property or in the same structure, with the intent of providing housing opportunities and of mitigating the impacts between new mixed office professional and residential developments. This zone is unique to the east side of Third Street between E and F Streets, and is intended as a relatively low-intensity transition from the residential uses along Third and public school across the street, to the more active mixed-use district to the east along Second Street.
Permitted uses

Day care facility
Housing-Single unit
