Sonoma County
Can this property be a vacation rental?
Sonoma County's rules decide it parcel by parcel. Type an address and I'll run it against the county's own vacation-rental determination — the same check I run for clients. This tool covers Sonoma County only — Napa runs a separate and considerably tighter regime, so ask me and I'll screen a Napa address by hand.
Only about 1 in 4 active listings can legally become a new vacation rental.
A first read from public county data — not a permit determination. Rural addresses can be imprecise; if it can't pin the exact parcel, I'll run it by hand.
