Santa Rosa FAQ
How many people can stay in a Santa Rosa short-term rental?
Chapter 20-48 limits overnight occupancy to 2 Short-Term Renters per bedroom, capped at 10 total. Children under 3 do not count. Bedroom count comes from the Sonoma County Assessor record.
Do daytime visitors count toward the cap?
No. Daytime Guests are allowed only between 8:00 AM and 9:00 PM and do not count against the overnight limit, but they must follow noise and parking rules. Anyone present during 9 PM-8 AM is counted as a Short-Term Renter.
Can I get an occupancy bump if I have a den or converted loft?
No. Santa Rosa uses the Sonoma County Assessor's bedroom count, not the host's listing. Converted spaces that are not assessor-recognized bedrooms do not increase the 2-per-bedroom limit.
Sonoma FAQ
How many guests can I host overnight in a 4-bedroom Sonoma County vacation rental?
Ten guests. Sec. 26-88-120's formula is 2 per sleeping room + 2 additional per property: 4 × 2 + 2 = 10. Children under 3 don't count. You cannot exceed this number even by one adult — it's a hard cap on the zoning permit.
Can I list more bedrooms than my permit allows if there's extra space?
No. The number of permitted guestrooms is locked in by the zoning permit and Permit Sonoma site plan. Advertising or marketing additional sleeping areas beyond the permit count violates Sec. 26-88-120 and can lead to citations or permit revocation.
What's the absolute maximum occupancy for any Sonoma County vacation rental?
Twelve overnight guests (excluding children under 3). To even approach this, you need a 5-bedroom rental at the by-right cap; anything above 5 guestrooms requires a discretionary Use Permit with documented sewage capacity and neighborhood compatibility findings.
