Lot Split

Updated 2026-07-18

Lot Split is the legal division of one parcel into two or more parcels through an applicable California subdivision process. Eligibility depends on local standards, the Subdivision Map Act, access, utilities, environmental constraints, and any special state-law pathway.

What it means

A conventional lot split commonly requires a tentative and parcel map; qualifying urban parcels may use a separate ministerial process under state law.

Why it matters for land decisions

Nominal acreage is not enough to establish subdivision yield.

  • Test net-area and frontage rules.
  • Account for infrastructure and dedications.

People also ask

Can any parcel be split in half?

No. Density, minimum lot dimensions, legal access, services, hazards, prior subdivisions, and statutory exclusions can prevent or reshape a split.

Is an SB 9 lot split available statewide?

SB 9 creates a pathway for qualifying urban single-family parcels, but statutory eligibility and local objective standards must be verified.
