Full Breakdown

110 sets the same occupancy math for both rental types: no more than two overnight occupants per bedroom plus two additional occupants. Under subsection (D), a hosted rental means the permittee occupies the property with the guests, and no more than two bedrooms in the dwelling may be furnished for compensation unless the entire dwelling is an accessory or secondary unit rented as a single party under one rental agreement. Under subsection (E), a non-hosted rental means the permittee does not occupy the property with the guests; the entire dwelling may be rented for compensation as long as the guests constitute one party under a single rental agreement, and it is capped at no more than 90 days of use as a non-hosted rental during any calendar year.

Non-hosted rentals also require a manager located within 45 miles of the City who must be available at all times and respond to complaints within one hour, the same response-time standard imposed on hosted rentals under (D)(2). 100, which run through a Conditional Use Permit process rather than the short-term rental permit.

Violations & Fines

Exceeding the per-bedroom occupancy formula or renting a non-hosted unit beyond the 90-day annual cap is a permit violation. Three or more verified violations within 12 months are grounds for the Planning Director to revoke the Short-Term Vacation Rental Permit under IZO §7.110(J), after which the property cannot operate as a short-term rental and a new application is barred for one year.

Frequently Asked Questions

How many guests can stay overnight at a Petaluma short-term rental?
No more than two overnight occupants per bedroom plus two additional guests, under IZO §7.110(D)(1) for hosted rentals and §7.110(E)(1)(b) for non-hosted rentals. The formula is identical either way; what changes is whether the host is present on the property.
What's the difference between a hosted and non-hosted short-term rental?
A hosted rental means the permittee lives on the property while guests stay there and may rent out no more than two bedrooms, per §7.110(D). A non-hosted rental means the whole dwelling is rented out with no resident host, capped at 90 days per calendar year under §7.110(E)(2), and requires a manager based within 45 miles.
Is there a yearly limit on renting my whole house as a non-hosted rental?
Yes, 90 days per calendar year under IZO §7.110(E)(2). There is no equivalent day cap for hosted rentals where the permittee stays on-site with guests, since that arrangement is instead governed by the bedroom-based occupancy formula and the two-bedroom cap on rooms furnished for compensation.
Does the occupancy limit change if my rental is an accessory dwelling unit?
The bedroom-based formula still applies, but §7.110(D)(1)(b) allows an entire accessory or secondary unit to be furnished for compensation as a hosted rental if the guests are treated as one party under a single rental agreement. Note that ADUs permitted after September 7, 2017 cannot be used as short-term rentals at all, under §7.110(C)(6).
