Find your lot's zone on the city zoning map, then read its row. Every status below was read from the San Jacinto Municipal Code use tables (read October 2026). Base zones only. General information, not legal advice — check with the city before you apply.

Zones where a duplex can go

San Jacinto's code calls this use “Two-Family”. Each row links to the use table it comes from. A zone marked “see note” has a condition in the code, for example upper floors only or a larger lot.

Zones where it is not allowed

RE, RR, RL, RVH, CN, CG, CR, OP, BP, IL, IH, OSG, OSR, PI.

What else applies

  • Standards for this use: Chapter 17.425.
  • State law: SB 9 (Gov. Code § 65852.21) allows two homes on most single-family lots with a ministerial permit, also where this table says no.
  • Not covered here: Article 8 definitions (e.g. Assembly/Meeting Facilities, Educational Facilities, Animal Keeping) and the Chapter 17.430 specific-use standards are not in the packet; Overlay zones (RAAB overlay) are not base zones. Overlay zones and specific plans can also change the answer.
