Where is a rooming or boarding house allowed in Marin County?

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

Marin County's code calls this use “Single Room Occupancy (SRO)”. 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.

R2, RX, RF, VCR, C1, CP, RCR, IP.

• Standards for this use: 22.32.085 (Single Room Occupancy).
• "Room rentals" (rooms in a single-family dwelling, limited to three or fewer bedrooms by 22.32.130(E)) is a separate row: P in all agricultural and single-family districts, R2, RMP, RX, RF, VCR, RMPC, C1, CP, AP, OP, H1; PF P(2); "-" in RCR, IP, OA. "Organizational houses" (U) are a third row. SRO standards: 22.32.085.
• Not covered here: Coastal zoning districts (Title 20, Tables 5-1, 5-2, 5-3, Coastal Agricultural, Residential and Commercial districts): only the intro section 20.62.040 is in the packet, the tables are missing.; Section 22.32 standards (22.32.030 animal keeping, 22.32.050 child care, 22.32.085 SRO, 22.32.095 homeless shelters, 22.32.150) and Article VIII definitions are not in the packet.; Combining districts (e.g. PF-RSP, San Geronimo Valley) can change allowed uses.. Overlay zones and specific plans can also change the answer.
