Full Breakdown
Short-term rental occupancy in Fontana is constrained by Uniform Housing Code space-per-occupant standards, fire and building code egress requirements, and any local STR ordinance caps. A common industry benchmark is two adults per bedroom plus two additional guests, but operators should not exceed what the dwelling can safely accommodate or what is allowed by code. California HCD Title 25 and the 2022 California Building Code require minimum floor area per occupant in sleeping rooms (typically 70 square feet for one person and 50 additional square feet per additional person). Maximum occupancy should be stated in the listing and house rules. Exceeding stated occupancy can trigger nuisance enforcement, business license action, and insurance issues. Events and parties that push occupancy beyond posted limits are typically prohibited. Contact Fontana Planning at (909) 350-7600 for STR-specific occupancy requirements.
