The process of dividing real property into more than four lots for the purposes of sale, lease or financing (including condominiums). State law requires approval and recordation of a map showing the division before sale, lease or financing of a new parcel can legally occur. Tract maps are acted on by the Planning Commission.
A land division occurs when a parcel of land is divided into two or more parcels, each of which can be sold and owned independently of the others. The Department of Planning & Building processes land division applications for subdivision entitlements according to the provisions of the state Subdivision Map Act and the County Real Property Division Ordinance.
