Lot Size & Street Design Standards

Subdivision lot sizes and frontage rules depend primarily on the underlying zoning designation in the Los Angeles Municipal Code and the subdivision type (tract map, parcel map, lot split). Street design - including required street widths, curb, gutter, sidewalk, and dedication requirements - is controlled by the Bureau of Engineering standards together with City Planning review. Applicants must coordinate grading, drainage, utilities and ADA compliance with the Department of Building and Safety and Bureau of Engineering prior to final map approval.
