Can I build a second dwelling unit in the R-1 (Single Family Residential) zone?
Yes, in limited areas. Section 15-4A-2(j) of the El Segundo Municipal Code allows second dwelling units to be built on property that has a common boundary with property zoned R-3 [Multi-Family Residential], P [Automobile Parking], C-RS [Downtown Commercial], C-2 [Neighborhood Commercial], C-3 [General Commercial], CO [Corporate Office], or MU [Mixed Use]. In addition, the property used for the second dwelling unit cannot be more than fifty feet (50′) wide and cannot consist of more than one lot.
