Occupancy Limits: Fairfield vs Vacaville
How do occupancy limits rules compare between Fairfield, CA and Vacaville, CA?
Fairfield has fewer restrictions than Vacaville.
Fairfield, CA
Solano County
Fairfield does not impose a per-bedroom or per-unit short-term rental occupancy cap because it does not separately permit sub-30-day rentals in residential zones. The default ceilings are: (1) California Uniform Housing Code occupancy standards adopted via the California Building Code (typically 2 persons per bedroom plus 1, with minimum floor-area standards) and (2) the international fire/building code load limits in California Building Code Chapter 10 for any lodging-classified use. Long-term rentals must comply with state HCD habitability standards.

Solano County
Vacaville has not codified an STR-specific occupancy cap (such as a flat 'two persons per bedroom plus two' rule or a 10-person maximum) because short-term rentals are not authorized in residential zones. For lawful lodging uses (hotels, motels, bed and breakfast inns in commercial/mixed-use districts), occupancy is set by the California Building Code occupant-load tables for the Group R-1 occupancy classification as adopted by Title 15 of the Vacaville Municipal Code, plus any use-permit-specific cap imposed by the Community Development Department at entitlement. Chapter 9.20 (Abatement of Community Safety Violations) reinforces that exceeding posted occupancy load at a public assembly where alcohol or drugs are accessible is itself a violation.

Fairfield FAQ
How many guests can I host in a Fairfield rental?
Fairfield does not impose an STR-specific occupancy cap. The default ceiling from the California Building Code's adopted Uniform Housing Code provisions is approximately 2 persons per bedroom plus 1 additional occupant, subject to minimum floor area (70 sq ft for the first occupant per sleeping room and 50 sq ft for each additional). For a 2-bedroom unit this works out to about 5 occupants. Tighter caps imposed by a host can raise familial-status discrimination concerns under the federal Fair Housing Act if not supported by legitimate business reasons.
Does Fire Code matter for a single-family home rental?
Generally only at major remodels or when the home is reclassified to a Group R-1 lodging use. A single-family home rented for 30+ days is a Group R-3 use and is governed by the California Residential Code rather than the Fire Code's R-1 occupant load formulas. A property reclassified to lodging (hotel/B&B) in a commercial zone falls under R-1 occupant load and assembly load rules in the California Fire Code Chapter 10, enforced by the Fairfield Fire Department.
Vacaville FAQ
How many guests can stay at a Vacaville short-term rental?
Vacaville does not authorize short-term rentals in residential zones and therefore has not codified a per-guest STR cap. For lawful lodging uses (hotels, motels, bed and breakfast inns in commercial/mixed-use districts), occupancy is set by the California Building Code occupant-load tables for Group R-1 as adopted by Vacaville Municipal Code Title 15, and may be further restricted by use-permit conditions imposed by Community Development at entitlement.
Can I host a large gathering at my Vacaville rental?
Gatherings at any address are subject to Chapter 9.20 (Abatement of Community Safety Violations), which treats it as a violation to exceed posted occupant load at a public assembly where alcohol or drugs are accessible. Chapter 9.61 (Social Host) layers liability where minors obtain alcohol at the gathering. Where the rental is operating without zoning authorization, the underlying use itself is enforced regardless of the gathering size.
Are there fire-marshal occupancy limits at Vacaville hotels?
Yes. The Vacaville Fire Department enforces California Fire Code occupant-load and means-of-egress requirements at lodging and assembly uses. Posted occupant-load placards are required at assembly spaces, and the Fire Marshal may inspect and order corrective action for overcrowding.
