Fast-track your SB 9 lot split with expert planning, entitlements, and full permitting support. Capitalize on unused extra land and create up to 4 new housing units.

What is an SB 9 Lot Split?

SB 9, known as the California Home Act, is a groundbreaking state law passed in 2021 that allows eligible single-family residential lots to be legally split into two separate parcels.

Each new parcel can then be developed with up to two housing units — meaning one original lot can potentially support four units total. This is a ministerial approval process, which means no public hearings and much faster approvals than traditional rezoning or variances.

It's designed to help increase housing supply while giving homeowners a powerful way to develop their property.

Legal Requirements

California State Laws & Requirements

Under California SB 9 law:

  • Property owners can split qualifying lots without needing city approval for the split itself in most cases
  • Each new lot can have one primary home plus one additional unit (ADU or duplex)
  • The law applies statewide unless a city has formally opted out
  • Minimum parcel size and other local zoning rules still apply after the split
  • It's designed to help increase housing supply while giving homeowners a powerful way to develop their property
