Camarillo, CA
Las Posas Estates
Las Posas Estates is a core-and-periphery neighborhood in northwest Camarillo, its center genuinely unincorporated Ventura County land recognized in the county's own general plan, while frontage along Las Posas Road, Carmen Drive, Arneill Road, and Temple Avenue sits inside city limits. Estate and equestrian character define it: large lots zoned for horse-keeping under county rules that tie the number of animals to lot size, and the private, member-owned Las Posas Country Club, operating continuously since 1958. Las Posas Equestrian Park, a two-acre district facility on Via Veneto, is the only park in the local recreation district that allows horses, connected to a trail through a mix of easements and county land. There's no community-wide gate here. Because jurisdiction is genuinely mixed, permitting and school-district boundaries should be confirmed by address; the county sheriff station, for instance, staffs a separate 21-deputy unincorporated-area patrol alongside the city's own police force. Shopping runs along the nearby Las Posas Road corridor, anchored by Ralphs-anchored Las Posas Plaza at the US-101 exit.

What defines it
- Core-and-periphery jurisdiction: the neighborhood's center is genuinely unincorporated Ventura County land, while frontage along Las Posas Road, Carmen Drive, Arneill Road, and Temple Avenue sits inside Camarillo city limits
- Large, county-zoned lots support horse-keeping under Ventura County's animal-unit rules, which tie the number of horses to lot size
- Las Posas Country Club, private and member-owned, has operated continuously since 1958
- Las Posas Equestrian Park, two acres on Via Veneto and run by the Pleasant Valley Recreation & Park District, stands alone locally: no other park in the district permits horses
- No community-wide gate; the country club and every area homeowners association checked make no gate or access-control claim
The Housing Stock
Las Posas Estates mixes large, individually owned county-zoned equestrian lots with incorporated-city frontage under one real-estate label, a split-jurisdiction pattern rather than one uniform tract or a single HOA-governed product.
Frequently asked
Is Las Posas Estates in the City of Camarillo, or is it unincorporated?
Neither answer covers the whole area. The neighborhood's center is genuinely unincorporated Ventura County land, recognized as such in the county's own general plan, while frontage along Las Posas Road, Carmen Drive, Arneill Road, and Temple Avenue, often folded into the same real-estate label, sits inside City of Camarillo limits. Confirm jurisdiction by parcel before assuming either answer.
Can I keep horses in Las Posas Estates?
On a qualifying county-zoned lot that meets the zone's own minimum size, yes, under Ventura County's animal-unit rules, which tie the number of horses allowed to lot square footage and require a setback for animal-keeping structures. It's an address-specific question, not a neighborhood-wide yes, so confirm the parcel's zone and size first.
Is Las Posas Estates a gated community?
No. Neither the Las Posas Country Club's own site nor any Las Posas-area homeowners association site checked makes a gate, guard, or access-control claim; the estate character here comes from large lots and equestrian zoning, not a controlled entrance.
Is Las Posas Country Club open to the public?
No, it's private and member-owned, operating continuously since 1958 according to the club's own site. It's a separate legal entity from the surrounding residential neighborhood, and buying a home nearby doesn't require or grant club membership.
Does living in the unincorporated core mean going through the county, not the city, for building permits?
Yes, for the documented unincorporated core. The Ventura County Resource Management Agency handles planning, building, and code enforcement there rather than the City of Camarillo's Community Development Department. Confirm which side of the line a specific parcel falls on before assuming either process applies.
Is Las Posas Estates near Camarillo Airport, and does noise affect it?
The airport's own published noise-abatement procedures for one runway use Las Posas Road as a pattern boundary, confirming genuine proximity to its flight pattern. Separately, the county's most recent noise-exposure-map study, accepted by the FAA in 2025, found no noise-sensitive residential properties within the airport's most affected contour lines for existing or forecast conditions, as of July 2026 (July 2026).
