Where is a single-family home allowed in Mountain View?

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

Mountain View's code calls this use “Single-family house or dwelling”. 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.

• Dual urban opportunity development (R1 only, P) and Small-lot single-family development (PUD in R2, R3, R4) are separate rows.
• State law: State law lets most single-family lots add an ADU and a JADU (California ADU law) and a second home or a lot split under SB 9 (Gov. Code § 65852.21).
• Not covered here: Zone names for R1, R2, R3, RMH, R4, CN, CS, CO, CRA, ML, MM are not stated in the packet; Planned Community (P) districts have no table (36.22.10: any use permitted in another district may be permitted after review); A, PF, F, U districts use lists, not tables; only cells that a list names outright are given; Overlay districts and specific plans are not in the packet. Overlay zones and specific plans can also change the answer.
