Sewer, septic and roads

Sewer service is not uniform. The County reports that the Camarillo Sanitary District serves part of Las Posas Estates and Oxnard’s treatment plant takes about 300 connections from another portion, yet most homes on the unincorporated streets sit outside the sanitary district’s boundary. Ask whether a home is on sewer or septic, and for septic, order an inspection and look for County Environmental Health records. County road data shows a few private or other segments among the County roads, so confirm who maintains the road to the lot.

Las Posas Estates questions, answered

Can I keep horses in Las Posas Estates?

There is no separate equestrian zone, but County RE zoning allows horses without a permit, within animal units tied to lot size: two on a lot of 20,000 to 24,999 square feet and about 3.7 on one acre, with a full-size horse counting as one. Below 20,000 square feet, a full-size horse needs a County waiver. Check recorded CC&Rs too, and compare Camarillo horse property for sale.

Is Las Posas Estates in a fire hazard zone?

Mostly not. On CAL FIRE’s March 2025 map, about three-quarters of homes on the unincorporated streets are outside any zone, while the eastern streets nearer the hills fall in Moderate, High or Very High zones. The seller’s Natural Hazard Disclosure confirms a specific address.

Could Las Posas Estates join the City of Camarillo?

The City’s General Plan places it in Camarillo’s sphere of influence, with portions subject to possible future annexation, but for now the County governs it. The question is old: in 1963 Oxnard tried to annex Las Posas Estates, which helped spur Camarillo’s 1964 incorporation.
