A Parcel Map is required to subdivide an existing parcel into four or fewer lots (a minor subdivision or urban lot split).  An SB 9 Urban Lot Split is the subdivision of one single-family zoned parcel into two parcels.  An Urban Lot Split is a type of minor subdivision that requires a Parcel Map. 

A Final Map is required to subdivide property into five or more lots, or when the resulting lot(s) will be further subdivided into five or more condominium units (a major subdivision).

The first step in subdividing property is to begin the process with the Planning Department. Upon either discretionary or ministerial approval of the subdivision, the parcel map or final map application process can be initiated with the Engineering Division of the Public Works Department.
