The California Subdivision Map Act (Map Act) governs the subdivision of land in California. Subdivision Section 66428 (b) of the Map Act is an ordinance by which a local jurisdiction may provide a procedure for filing a map waiver request. The requirement for a Parcel Map can be waived pursuant to Ventura County Subdivision Ordinance Section 8202-3. However, before waiving a Parcel Map, the County must make specified findings, including, but not limited to, a finding that the proposed "subdivision" complies with the Map Act and to any local subdivision ordinance, and the subdivision meets the requirements relating to improvement and design, floodwater drainage control, public road improvements, sanitary disposal facilities, water supply, availability, and environmental protection.


The County of Ventura processes six different types of Parcel Map Waivers:

1. Ministerial Lot Line Adjustment (LLA)

A boundary line adjustment between two or more adjacent legal lots under the same or different ownership, wherein land taken from one lot is added to an adjacent lot, and neither a greater nor lesser number of lots than originally existed is created.

The LLA must meet all the requirements detailed in Section 8202-3 (a) of the Ventura County Subdivision Ordinance, and Section 66412 (d) of the Subdivision Map Act, including that the LLA is limited to four lots.

Please click here for the Ministerial Lot Line Adjustment application.


2. Large Lot Subdivisions (LLS)

A subdivision that creates four or fewer lots, including any remainder parcel, of at least 40 acres in size.

LLSs must meet all the requirements detailed in Section 8202-3 (b) of the Ventura County Subdivision Ordinance.

Unlike the other five Parcel Map Waiver types, which require the submittal of the attached application documents, LLSs require the submittal of the Discretionary Permit Application Packet. Please click here for the Large Lot Subdvisions Application.


3. Lot Elimination Subdivisions (LES)

A process that merges existing legal lots and then adjusts the property boundaries of one or more of the parcels to eliminate one or more of the previously existing, without otherwise altering the boundaries of the latter group of lots. See graphic below for visual representation of the LES process.

LESs must meet all the requirements detailed in Section 8202-3 (c) of the Ventura County Subdivision Ordinance.

4. & 5. Voluntary Mergers (VM)

A subdivision that creates one new lot out of two or more previously existing lots
by eliminating the lot lines that separate such lots from each other.

4.) Ministerial – Where all existing lots are “Legal Lots,” pursuant to Section 8202-3 (d) of the Ventura County Subdivision Ordinance and Section 66412 (d) of the Subdivision Map Act.

5.) Discretionary – Where one or more existing lots involved in the voluntary merger is an illegal lot, pursuant to Sections 8212-4 through 8212-4.2 of the Ventura County Subdivision Ordinance, Conditional Certificate of Compliance conditions may be applied.

VMs must meet all the requirements detailed in Section 8202-3 (d) of the Ventura County Subdivision Ordinance.

6. Conservation Subdivision

A Parcel Map Waiver/Conservation Subdivision occurs when an existing legal lot is divided into two new legal lots for the purposes of providing resource protection for one or both of the resulting lots. This type of subdivision allows the creation of lots that are smaller than the underlining zoning requirements.

CSs must meet all the requirements detailed in Section 8202-3 (f) of the Ventura County Subdivision Ordinance.
