Fallbrook, CA Short-Term Rentals: Parking Rules (2026)

Unlike STR-licensing jurisdictions that mandate a set number of on-site spaces per rental, unincorporated San Diego County imposes no STR-specific parking standard, because no County short-term rental ordinance exists. Parking is instead governed by the off-street parking provisions of the County Zoning Ordinance that apply to the underlying residential use, and, in fire-prone areas, by Fire Code and County requirements for adequate emergency-vehicle access and clear roadways. Many unincorporated communities are rural, with private driveways, narrow roads, and no street parking, so operators are practically expected to keep guest vehicles on the parcel and out of the public right-of-way. The County's Transient Occupancy Tax requirements, the principal STR rule, say nothing about parking. Because the County has not adopted dedicated STR parking ratios, any claim of a specific number of required guest spaces for an unincorporated STR would be unsupported by County code. Operators should confirm the residential parking minimums for their zone with Planning & Development Services and avoid creating roadway obstructions that could draw code-compliance or fire-access complaints.
