Subdivision Maps

A subdivision map is a detailed representation of the division of a tract of land into smaller parcels or lots. The number of lots or parcels is determined by local ordinances and state laws. Subdivision mapping is typically a two-step process requiring a tentative map and a final map. The tentative map illustrates the proposed improvements and lot configurations, while the final map, which can be either a parcel map (for four parcels or less) or a tract map (for five or more lots), conforms to city and county governmental conditions.

The primary reasons for subdividing a parcel of land include developing smaller lots for real estate transactions, legally separating sections of land for commercial use, or constructing different building types on certain parcels. Additionally, a lot line adjustment process may be used to change property lines of existing parcels. All these processes are highly regulated by state and local laws to ensure compliance and orderly development.
