Santa Rosa Valley is unincorporated Ventura County tucked between Camarillo to the south and Moorpark to the north. Equestrian zoning is predominant, lots run from 1 to 5+ acres at price points that look like a different planet from Hidden Hills or Bell Canyon, and Camarillo High School serves most of the area. May 2026 median runs $1.4M to $1.8M depending on parcel. The wine and avocado country to the north and west makes the area feel structurally rural in a way most of the LA-County equestrian belt has lost. I sell horse property across the region.

Where Santa Rosa Valley sits
Santa Rosa Valley is unincorporated Ventura County land running roughly east-west between the Santa Rosa Mountains to the south and the Las Posas Hills to the north. The community sits between the City of Camarillo (just south, down Santa Rosa Road) and the City of Moorpark (just north, over the hills). Population is approximately 3,500 across the recognized community boundary. ZIP code 93012 is shared with Camarillo — mail addresses to Santa Rosa Valley are formally Camarillo addresses.
Jurisdictionally everything is Ventura County. There is no incorporated city. Land-use decisions go through the Ventura County Resource Management Agency and the Board of Supervisors (District 2 typically). Law enforcement is Ventura County Sheriff's Camarillo / Thousand Oaks station. Fire is Ventura County Fire Protection District. The Santa Rosa Valley Municipal Advisory Council (MAC) provides community input to the county on planning matters.
Access is via Santa Rosa Road from the south (the main connection to Camarillo and the 101) and Moorpark Road / Grimes Canyon from the north (the connection to Moorpark and the 118). The 101 freeway is 5-10 minutes from most addresses; the 118 is 10-15 minutes via Grimes Canyon. Drive time to Thousand Oaks is 15-20 minutes, to Westlake Village 20-25 minutes, to Burbank Airport 50-60 minutes via the 101 east to the 134.
Ventura County equestrian zoning in Santa Rosa Valley
Most Santa Rosa Valley parcels carry Ventura County RE (Rural Exclusive) or AE (Agricultural Exclusive) zoning, both of which allow horse-keeping as a by-right use. RE is the more residential designation, typical for 1-2 acre lots. AE is the agricultural designation typical for 2-acre and larger lots and is the most permissive zone in the area for commercial training, boarding, or breeding operations (with a Conditional Use Permit). The county publishes the zoning map at vcrma.org.
Specific horse-keeping rules under Ventura County code: corrals must sit at least 50 feet from neighboring dwellings, 35 feet from property lines. Stables larger than 200 square feet require a county building permit. Manure storage must be covered and managed per the Ventura County agricultural best-practice standard, which allows on-property composting on AE-zoned parcels with appropriate setbacks. Animal-unit counts allow up to 2 large animals per acre on RE, more on AE with CUP.
Unlike Hidden Hills or Bell Canyon, Santa Rosa Valley has no central HOA and no architectural review committee. Building, fencing, and corral construction happens at the parcel level with only county code as the constraint. The trade-off: more individual freedom, more variability in neighbor-to-neighbor build standards, and slightly more code-enforcement risk if a neighbor complains about an unpermitted structure.
- RE (Rural Exclusive) typical for 1-2 acre parcels — horse-keeping by-right
- AE (Agricultural Exclusive) for 2+ acre parcels — most permissive for commercial use
- 50-foot corral setback from neighboring dwellings
- County building permit for stables over 200 sq ft
- Up to 2 large animals per acre on RE; more on AE with CUP
- No central HOA — parcel-level rules and individual flexibility
- On-property manure composting allowed on AE with proper setbacks
Price tiers and recent comps
Santa Rosa Valley closed May 2026 at a median sale price of approximately $1.65M across roughly 5-9 closings in the prior 90 days. Active inventory runs 12-22 listings. Days on market average 52, slightly slower than the broader Camarillo market driven by the niche buyer pool. The range spans from $1.3M for smaller homes on 1-acre lots to $3M+ for renovated horse properties on 5+ acre parcels.
Land matters more here than in the LA County equestrian belt because the agricultural identity is real. A 5-acre parcel with avocado, citrus, or wine-grape rows in addition to horse facilities carries a fundamentally different value proposition than a 1-acre residential horse parcel. The agricultural-overlay properties trade at a premium relative to pure-residential horse parcels of similar gross acreage.
| Tier | Description | May 2026 range |
|---|---|---|
| Entry | 1-acre home, basic horse facility | $1.3M - $1.55M |
| Core | 1.5-2.5 acre, working facility, updated home | $1.55M - $2.0M |
| Premium | 3-5 acre with arena, ag overlay possible | $2.0M - $3.0M |
| Top | 5+ acre estate with commercial-capable facility | $3.0M - $5M+ |
Schools serving Santa Rosa Valley
Santa Rosa Valley elementary is served by Pleasant Valley School District (PVSD) — the same district that serves much of Camarillo. The specific campus depends on the address, with Santa Rosa Technology Magnet School serving many of the area's families and other PVSD elementaries picking up remaining attendance zones. Middle school is also PVSD. High school is Camarillo High School under the Oxnard Union High School District.
PVSD and Oxnard Union HSD perform around or above the Ventura County medians on the California School Dashboard. Camarillo High specifically draws students from across Camarillo proper, Santa Rosa Valley, and some Somis boundaries. Specific attendance assignments are published at pleasantvalleysd.org and oxnardunion.org. Verify specific address assignments before tying a purchase to a school. I don't steer buyers to or from particular campuses.
Trails, community infrastructure, and the wine-country adjacency
There's no single Santa Rosa Valley trail council the way there is in Bell Canyon or Hidden Hills. Riding access comes from a combination of county-managed corridors, individual recorded easements between neighboring parcels, and adjacent open space. The Santa Monica Mountains Conservancy and the Conejo Open Space Conservation Agency manage some adjacent terrain. The Camrosa Water District has historically allowed limited equestrian use on some maintenance easements.
The Santa Rosa Valley Municipal Advisory Council functions as the community's informal trail and land-use advocacy body, coordinating with the county on planning matters. The MAC meets publicly and is the right venue for buyers to understand the community's positions on growth, trail access, and any pending zoning changes.
The wine and ag country to the north and west is part of the practical lifestyle of the area. Somis, Las Posas, and the broader Camarillo wine country sit adjacent. Several Santa Rosa Valley parcels carry working agricultural use — wine grapes, citrus, avocado — in addition to horse facilities. Olsen's Grain in Camarillo, multiple local farriers, and the Steinbeck equine vet group all serve the area.
Hazards: FHSZ on canyon edges, insurance, and evacuation
Santa Rosa Valley sits in a mixed fire zone. Parcels along the Santa Rosa Mountains hillside on the south edge and the Las Posas Hills on the north edge sit in CAL FIRE Very High FHSZ. The valley floor itself is lower risk (High or Moderate FHSZ depending on parcel). The Thomas Fire of 2017 and the Hill Fire of 2018 affected the broader Ventura County footprint but did not burn through the valley floor at scale. Specific parcel FHSZ designation should be confirmed at the CAL FIRE viewer.
Defensible space follows PRC 4291: 100 feet around all structures. Outbuildings on horse parcels — stables, hay storage, tack rooms — each carry their own clearance. Annual fire inspection by Ventura County Fire is mandatory in FHSZ parcels. Insurance market in Santa Rosa Valley is meaningfully healthier than in Hidden Hills or Bell Canyon because most valley-floor parcels sit outside Very High FHSZ — quotes typically run $2,500-$8,000 per year depending on parcel and structures.
Large-animal evacuation routes from Santa Rosa Valley go primarily to the Camarillo Equestrian Center (a county-coordinated evacuation site) and to the Ventura County Fairgrounds in Ventura proper. Local horsemen's associations coordinate trailer-pool networks for emergency evacuation. The MAC publishes the current evacuation routing as part of community emergency preparedness materials.
Well water, septic, and Camrosa Water District service
Most Santa Rosa Valley parcels receive municipal water through the Camrosa Water District. A smaller number of larger AE-zoned parcels remain on private wells, typically combined with Camrosa connections for backup. Septic is near-universal — there is no central sewer in the valley. Verify Camrosa connection status, allocation, and current rates during escrow. Camrosa rates have increased meaningfully in recent years and are a material household-cost line item.
Septic inspection should include tank pump-out, leach-field perc test, and review of any county compliance filings. Failed leach fields on horse parcels typically run $30K-$55K to replace once today's setback rules are triggered. Stable wash water must be diverted to a separate sand filter or evapo-transpiration drain — it cannot enter household septic. AE parcels with on-property composting need separated drainage as part of the compost system design.
Common buyer scenarios in Santa Rosa Valley
The agriculture-curious horse owner — buyer who wants horses plus a working row crop or orchard — is uniquely served by Santa Rosa Valley AE parcels. The combination of horse-keeping and active agricultural use is rare in the LA County equestrian belt and is one of the area's structural differentiators. Williamson Act eligibility adds a property-tax dimension to this scenario.
The Camarillo / Moorpark family with horses uses Santa Rosa Valley as the rural-character alternative to in-town residential lots. Schools (PVSD plus Camarillo HS) keep the kids inside familiar systems while the parcel size and zoning deliver horse-keeping that's impossible inside Camarillo proper. Price tier under $2M for a working horse property is accessible to a wider buyer pool than Hidden Hills or Bell Canyon.
The escape-from-LA buyer who wants real rural identity with reasonable freeway access. Santa Rosa Valley is 10 minutes from the 101 and feels two hours away. The 25-minute drive to Westlake Village, the 50-60 minute drive to Burbank Airport, and the 90-minute drive to LAX put it in reach without the urban friction. Compared with the Conejo Valley alternatives, Santa Rosa Valley trades acreage and quiet for slightly worse freeway proximity.
What I tell clients about Santa Rosa Valley
Santa Rosa Valley delivers structural value that's hard to match anywhere else in the equestrian belt — real rural character, working ag overlay on many parcels, a healthier insurance market on valley-floor properties, and Camarillo schools at a fraction of the Hidden Hills price tier. The trade-offs are real: no central HOA means inconsistent neighbor build standards, slightly slower freeway access, and a smaller buyer pool that affects exit liquidity.
The most common mistake I see is buyers underestimating the zoning lookup. RE versus AE matters enormously for what you can actually do with the parcel. A 2-acre RE parcel and a 2-acre AE parcel are not equivalent. Pull the specific zoning before offering. Verify Williamson Act status. Check the Camrosa connection and water allocation. Pull the septic record. These are the diligence items I push hardest on.
Frequently Asked Questions
Is Santa Rosa Valley part of Camarillo?
Mailing addresses in Santa Rosa Valley are formally Camarillo addresses (ZIP 93012), but the community is unincorporated Ventura County — not part of the City of Camarillo. Land-use decisions go through the Ventura County Resource Management Agency and the Board of Supervisors, not the City of Camarillo. The Santa Rosa Valley Municipal Advisory Council provides community input on planning matters. Practical lifestyle ties (schools, shopping, vet services) connect Santa Rosa Valley closely to Camarillo proper, but jurisdictionally the community is a distinct unincorporated area.
What does it cost to buy a horse property in Santa Rosa Valley?
Santa Rosa Valley closed May 2026 at a median sale price of approximately $1.65M across roughly 5-9 closings in the prior 90 days. The range runs from $1.3M for smaller homes on 1-acre lots to $3M+ for renovated horse properties on 5-acre parcels and beyond. AE-zoned parcels with agricultural overlay (citrus, avocado, wine grapes) trade at a premium relative to pure-residential horse parcels of comparable acreage. Days on market average 52. Land condition, working facility, and Williamson Act status drive most of the within-tier variation.
What's the difference between RE and AE zoning?
Both RE (Rural Exclusive) and AE (Agricultural Exclusive) Ventura County zones permit horse-keeping by right. RE is the more residential designation, typical for 1-2 acre lots, allowing up to 2 large animals per acre. AE is the agricultural designation, typical for 2+ acre lots, more permissive on animal counts and the only zone in the area that allows commercial training, boarding, or breeding operations with a Conditional Use Permit. AE parcels are eligible for Williamson Act contracts. Pull the specific zoning at the parcel before offering — RE and AE carry materially different rights.
What schools serve Santa Rosa Valley?
Elementary and middle school are Pleasant Valley School District (PVSD), the same district serving much of Camarillo. Santa Rosa Technology Magnet School serves many Santa Rosa Valley families; other PVSD campuses pick up remaining attendance areas. High school is Camarillo High School under the Oxnard Union High School District. Verify specific address assignments at pleasantvalleysd.org and oxnardunion.org before tying a purchase decision to a school. I do not steer buyers to or from particular campuses.
Is there an HOA in Santa Rosa Valley?
There is no central Santa Rosa Valley HOA. Building, fencing, and corral construction happen at the parcel level with only Ventura County code as the constraint. The Santa Rosa Valley Municipal Advisory Council provides community input to the county on planning matters but has no enforcement authority. The absence of an HOA delivers more individual freedom but produces more variability in neighbor-to-neighbor build standards. Specific gated micro-communities within the area (a small number) carry their own private HOAs — verify whether any applies to a specific parcel.
Can I run a commercial horse operation in Santa Rosa Valley?
AE-zoned parcels in Santa Rosa Valley can host commercial training, boarding, or breeding operations with a Conditional Use Permit from Ventura County. The CUP process takes 4-9 months and triggers parking, signage, traffic, and neighbor-notification review. RE-zoned parcels do not allow commercial operations regardless of CUP. Plan the entitlement timeline into your acquisition pro forma and verify the specific zoning at the parcel before offering. Existing operations with grandfathered CUPs can be acquired with the CUP intact, which is faster than starting fresh.
Is Santa Rosa Valley in a fire zone?
Partial. Parcels along the Santa Rosa Mountains hillside on the south edge and the Las Posas Hills on the north edge sit in CAL FIRE Very High FHSZ. The valley floor itself is lower risk (High or Moderate FHSZ depending on parcel). Verify specific parcel designation at the CAL FIRE viewer. Insurance market on valley-floor properties is meaningfully healthier than in Hidden Hills or Bell Canyon; quotes typically run $2,500-$8,000 per year. Hillside parcels carry the same insurance friction as the LA County equestrian belt — get the quote in writing before contingency removal.
How does water service work in Santa Rosa Valley?
Most parcels receive municipal water through the Camrosa Water District. A smaller number of larger AE-zoned parcels remain on private wells, typically combined with Camrosa connections for backup. Septic is near-universal — there is no central sewer. Verify Camrosa connection status, allocation, and current rates during escrow. Camrosa rates have increased meaningfully in recent years. Septic systems require inspection. Stable wash water must be diverted to a separate sand filter or evapo-transpiration drain — it cannot enter household septic.
