Urban Lot Splits and Two-Unit Projects

The State of California adopted Senate Bill 9 (SB 9) in September 2021, which allows for urban lot splits and two-unit projects. The changes, which became effective on January 1, 2022, required local agencies to approve qualifying applications to subdivide single-family residential zoned lots into a maximum of two lots and allow for the construction of two primary units on each new lot. A ministerial approval means that no public hearing, noticing, or discretion is involved in the review and approval of the project.

For additional information regarding SB 9’s approval process (including general eligibility, application requirements, and project review), please contact the Planning Division via email at Planning@cityoflagunaniguel.org or by phone at (949) 362-4300.
