Find your lot's zone on the city zoning map, then read its row. Every status below was read from the El Monte 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
El Monte's code calls this use “Residential dwellings, two-family, two (2) attached or detached on a lot”. 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

- 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.
