California city profile
Camarillo is an incorporated city in Ventura County. Projects here follow Camarillo's own zoning and building rules on top of the county-level environmental rules that apply across Ventura County. The county rules most likely to catch a project applicant off guard are listed below.
These Ventura County rules apply to projects in Camarillo, on top of any city-specific Camarillo requirements.
Agricultural and open space land in the county cannot be rezoned for urban development without a countywide vote — a voter-protected boundary extended through mid-century. Projects that assume a simple General Plan amendment may find a ballot measure is the only path.
The county protects oaks and sycamores at a remarkably low trunk circumference threshold — small trees that would be entirely unregulated in most California counties require a removal permit here, and unauthorized removal triggers a replacement penalty that is among the harshest in the state.
The Ojai Planning Area operates under separate air quality thresholds that are far stricter than the rest of the county and far below the Los Angeles district's standards — projects in or near Ojai that generate modest emissions can exceed significance thresholds that would pose no issue elsewhere.
Projects that bring residential development adjacent to active farming operations must provide substantial buffers and vegetative screening under the county's Right to Farm provisions — a requirement that applies even on small parcels and can significantly constrain building footprint.
Two catastrophic fires swept through the county in consecutive years, burning vast stretches of foothill and mountain terrain that now face post-fire hazard review and dramatically expanded fire hazard zone designations — projects in foothill or mountain terrain need current fire hazard mapping, not older versions.
