Where is a duplex allowed in Colton?

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

Colton's code calls this use “Dwelling—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.

• 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: Residential Table E, commercial Table F, open space Table H, P-I Table I and corridor Table J have no Emergency Shelter row (not allowed under 18.06.060 B). The same not-listed rule applies to any use below with no row in a table.; Note on the packet text: Table F is interrupted by a repeated 'E. Residential Districts Table' heading before 'Recycling Processing Facility—Heavy'. The rows after it (through 'Wholesaling', including 'Single-Room Occupancy Facility') continue Table F alphabetically and are read as Table F.. Overlay zones and specific plans can also change the answer.
