What is a SB 9 or an Urban Lot Split?


Senate Bill 9 (SB 9) went into effect on January 1, 2022, and permits 2-unit development and lot splits, under specified circumstances, on parcels zoned for single-dwelling unit development. SB 9 reviews are required to be considered ministerially, without discretionary review or public hearing, if the proposed housing development meets certain objective requirements. 

For questions regarding SB 9 and urban lot splits, please contact Planning staff at planning@sanjuancapistrano.org. The following standards apply:

  • Allows up to four (4) units up to 800 square feet on a single-family residentially zoned lot through an SB 9 Urban Lot Split.
  • Requires the City to approve either or both:
    • SB 9 2-Unit Housing Development: A housing development of no more than two units (duplex) on a single-family residentially zoned lot.
    • Urban Lot Split: Allows for a lot split (a single-family lot split into two lots).
  • Prohibits the City from requiring more than one (1) parking space provided the lot is located within ½ mile walking distance of either a high-quality transit corridor or a major transit stop.

 Please note the list is not comprehensive, and all relevant Municipal Code sections should be reviewed for applicable standards. (SJCMC Sec.9-3.538,Article 7.Urban Lot Splits,)

Please email Planning@sanjuancapistrano.org a site plan with your preliminary lot line for staff to review and identify potential concerns prior to submitting for a Tentative Parcel Map with the Comprehensive Development Application.
