Somis is unincorporated Ventura County agriculture between Camarillo and Moorpark — avocado, citrus, wine grapes, plus working horse property. ZIP 93066. Lots run from 1 acre at the village core to 40+ acres on the working ranches in the hills. Inventory is small. Days on market is the slowest of any community I cover — typically 45 to 60 days and sometimes much longer for the larger ranches. Somis School District serves elementary; Camarillo High serves high school. This is real ag country with structural appeal for a specific buyer profile. I sell horse and ag property across the region. I'm Brian Cooper. DRE# 01434286.
Where Somis sits
Somis is an unincorporated agricultural community in Ventura County, with a small village core at the intersection of Somis Road (Highway 34) and Los Angeles Avenue (Highway 118). The community runs along the 118 corridor from the eastern edge of Camarillo to the western edge of Moorpark. Population is approximately 1,200 in the core community, with the broader agricultural footprint of working ranches extending into the Las Posas Valley and the South Mountain area. ZIP code 93066 is Somis-exclusive.
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. The Ventura County Sheriff covers law enforcement; Ventura County Fire Protection District covers fire. Somis has no Municipal Advisory Council — community input on county planning matters happens through ad hoc community organizing.
Access is via the 118 freeway, which runs through the community. Drive time to Camarillo is 10 minutes via the 118 west or via Somis Road south. Drive time to Moorpark is 10 minutes via the 118 east. Drive time to Westlake Village is 25 minutes via the 23 south. Drive time to Burbank Airport is 55-65 minutes via the 118 east. The 118 is the practical commuter route — Somis residents working in the west San Fernando Valley typically use it rather than dropping south to the 101.
Somis agricultural and equestrian zoning
Most Somis parcels carry Ventura County AE (Agricultural Exclusive) zoning, the most permissive zone in the area for combined agricultural and equestrian use. AE allows row crops, orchards, vineyards, livestock, and horse-keeping by right. Commercial training, boarding, or breeding operations require a Conditional Use Permit but the CUP path is well-established in Somis with multiple existing operations carrying grandfathered approvals. Village-core smaller parcels carry RE (Rural Exclusive) zoning.
Specific horse-keeping rules under Ventura County AE code: corrals must sit at least 50 feet from neighboring dwellings, 35 feet from property lines. Stables larger than 200 square feet require county building permit. Manure storage allowed on-property with appropriate setbacks, including composting for working ag use. Animal-unit counts on AE parcels are essentially unrestricted within the practical limits of pasture and water — this is the most permissive horse-keeping environment in the region.
Williamson Act contracts are common on Somis ag parcels. The contract reduces property tax assessment in exchange for a long-term commitment to agricultural use and a development restriction. Williamson Act parcels carry both the property-tax benefit and the use restriction; understand both before you buy. Many Somis ranches are also in agricultural easement programs through the Ventura County Land Trust — verify status during diligence.
- AE (Agricultural Exclusive) primary — most permissive ag + horse zone in region
- RE (Rural Exclusive) on village-core smaller parcels
- 50-foot corral setback, 35-foot from property line
- Animal-unit counts essentially unrestricted within water and pasture capacity
- Commercial CUP path well-established — multiple existing operations
- Williamson Act contracts common — property-tax benefit plus use restriction
- On-property manure composting allowed for working ag use
Price tiers and recent comps
Somis closed May 2026 at a median sale price of approximately $1.95M across roughly 3-6 closings in the prior 90 days. Active inventory is structurally small — frequently fewer than 10 active listings. Days on market average 55, and ranch parcels regularly exceed 120 days on market because the buyer pool for working ag is narrow and qualified. The range spans from $1.5M for smaller homes on 1-2 acre lots in the village to $4.5M+ for working ag ranches on 20+ acre parcels with established orchards.
Land value carries more weight in Somis pricing than in any other community I cover. A 10-acre working avocado ranch is priced primarily on the orchard, the water rights, and the production history, with the dwelling as a secondary value. A 10-acre vacant ag parcel is priced primarily on slope, water, and developable footprint. Established wine-grape parcels carry vineyard-establishment cost premiums that don't always translate into a matching market premium — verify the ag economics during diligence.
| Tier | Description | May 2026 range |
|---|---|---|
| Village | 1-2 acre home in core village | $1.5M - $1.85M |
| Core ranch | 3-10 acre working horse or hobby ag | $1.85M - $2.75M |
| Working ranch | 10-20 acre with orchard or vineyard | $2.75M - $4.0M |
| Estate ranch | 20+ acre established ag plus residence | $4.0M - $7M+ |
Schools serving Somis
Somis elementary is served by the Somis School District — a small one-campus K-8 district. The single campus is Somis Elementary School. High school is Camarillo High School under the Oxnard Union High School District, the same high school that serves Camarillo proper and most of Santa Rosa Valley. Parcels on the western edge of the Somis area near the Moorpark border may fall inside the Moorpark Unified School District; verify specific address assignments before tying a purchase to a school assumption.
The Somis School District performs around the Ventura County median on the California School Dashboard. Camarillo High likewise. The small K-8 footprint is part of the community's identity — families who want the rural-school experience cite it as a driver. Specific assignments are published at somissd.org and oxnardunion.org. I don't steer to or from particular campuses.
Trail and community infrastructure in Somis
Somis has no formal trail council and no central HOA. Riding access comes from a combination of agricultural-road easements between neighboring ranches, county-maintained corridors along Somis Road and Las Posas Road, and access into adjacent open space. The South Mountain area on the southern edge of Somis carries some informal trail use. Most Somis horse owners ride primarily on their own acreage and on neighboring ranches by long-standing informal agreement.
Local community infrastructure is centered on Somis Road and Highway 34. The Somis Country Store and the Somis Nut House serve as informal community gathering points. Olsen's Grain in Camarillo and Conejo Valley Feed in Newbury Park are the closest feed retailers. Mobile feed delivery from Western Milling and similar serves the area weekly. Equine vet services are available through Steinbeck Country Equine in Camarillo and a small number of practitioners covering the Las Posas / Somis area.
Wine country adjacency is a real lifestyle factor. The Ventura County wine appellation includes a number of Somis-adjacent vineyards. Some Somis ag parcels carry working wine-grape rows; others are surrounded by them. The agricultural identity is intact in a way that's rare in the broader region — this is functioning farmland, not aesthetic farmland.
Hazards: FHSZ on hillside parcels, insurance, and evacuation
Somis sits in mixed fire zones. Parcels along South Mountain on the southern edge and along the Las Posas Hills on the northern edge sit in CAL FIRE Very High FHSZ. Village-core and valley-floor parcels sit in lower-risk zones (Moderate to High FHSZ depending on parcel). The Thomas Fire of 2017 and the Maria Fire of 2019 affected portions of the broader area. Specific parcel FHSZ designation should be confirmed at the CAL FIRE viewer before offering.
Defensible space follows PRC 4291: 100 feet around all structures. Outbuildings — stables, hay storage, tack rooms, ag-equipment sheds — each carry their own clearance. Insurance market on valley-floor Somis properties is meaningfully healthier than in Hidden Hills or Bell Canyon; quotes typically run $2,500-$9,000 per year. Hillside parcels and parcels with large ag structures (hay barns, equipment buildings) face more friction.
Large-animal evacuation routes from Somis go primarily to the Camarillo Equestrian Center and the Ventura County Fairgrounds in Ventura. Local ranchers historically operate informal trailer-pool networks during emergencies. Verify your specific evacuation routing with Ventura County OES at the parcel level — the small-population nature of Somis means evacuation planning has historically been less formalized than in the LA County equestrian belt.
Well water, Ventura County Waterworks 19, and septic
Water service in Somis is split. Many parcels receive municipal water through Ventura County Waterworks District 19. Larger ag parcels — particularly working orchards and vineyards — typically combine District 19 connection with private agricultural wells, and the well capacity is frequently the limiting factor on what the parcel can grow and how many horses it can support. Confirm District 19 connection status and water allocation, and pull the well report on any parcel with private well use.
Well capacity testing on ag-scale wells should include sustained-pull gallons-per-minute over a documented duration, lab-panel water quality, and review of the historical pumping record. A weak ag well is a frequent deal-killer that surfaces only at the inspection stage if you skip the diligence. Replacing an ag well in Somis can run $40K-$150K depending on depth and yield target.
Septic is universal — there is no central sewer. 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 $35K-$65K to replace. Stable wash water and manure runoff must be managed through separate drainage. AE parcels with on-property composting need specific drainage design as part of the compost system.
Common buyer scenarios in Somis
The working ag buyer with horses — buyer acquiring an orchard, vineyard, or row-crop operation and keeping horses alongside — is the historical core of the Somis market. The AE zoning, the Williamson Act tax structure, and the established ag-supply and labor networks make Somis the strongest community in the region for this profile. The acquisition includes due diligence on ag economics, water rights, labor, and equipment that's not typical in pure-residential equestrian property.
The lifestyle ag buyer — buyer who wants a small avocado or wine-grape operation as a working hobby alongside a horse-keeping residence — has strong fit in Somis on 5-15 acre parcels. The ag overlay generates real income (typically modest), the property-tax structure can include Williamson Act benefit, and the community accepts the part-time-ag buyer as part of the structural mix.
The privacy-and-acreage buyer who wants real distance from neighbors uses Somis for the structural lot sizes. A 10-acre parcel in Somis is achievable in the mid-$2M range, which is impossible in Hidden Hills or Bell Canyon at any price. The trade-offs: slower freeway access, smaller buyer pool on exit, and a more rural identity that suits some buyers and not others.
What I tell clients about Somis
Somis is the most structurally rural community in the region I sell. The agricultural identity is intact, the zoning is the most permissive for combined ag and horse use, and the price tier per acre is the most favorable in the area. The trade-offs are real: small inventory means patience, slow days on market means exit liquidity is narrower, and the diligence load on water rights, well capacity, and ag economics is heavier than in any other community.
The biggest mistake I see is buyers approaching Somis ranch acquisition with a residential-real-estate mindset. The dwelling is secondary; the orchard, the water, the labor, and the ag history are the actual product. Pull the production history. Verify water rights and well capacity. Understand the Williamson Act status. Talk to neighboring ranchers. The Somis community is small enough that this is achievable on a single weekend of pre-offer diligence — and it's the difference between a good buy and an expensive regret.
Frequently Asked Questions
Where is Somis, California?
Somis is an unincorporated agricultural community in Ventura County between Camarillo and Moorpark along Highway 118. ZIP code is 93066. The village core sits at the intersection of Somis Road (Highway 34) and Los Angeles Avenue (Highway 118). Population is approximately 1,200 in the core community, with working agricultural ranches extending into the Las Posas Valley and the South Mountain area. The 118 freeway runs through the community providing direct access east toward Moorpark and the San Fernando Valley and west into Camarillo.
What's the difference between Somis and Santa Rosa Valley?
Both are unincorporated Ventura County equestrian communities, but Somis is more structurally agricultural. Somis carries predominantly AE (Agricultural Exclusive) zoning with established orchards, vineyards, and row crops as part of the working fabric. Santa Rosa Valley carries more RE (Rural Exclusive) zoning with horse-keeping primary and ag as overlay. Somis lot sizes run larger (1-40+ acres versus 1-5 acres typical in Santa Rosa Valley). Both feed Camarillo High School. Somis elementary is Somis School District (one campus); Santa Rosa Valley is Pleasant Valley School District.
What does a Somis horse or ag ranch cost?
Somis closed May 2026 at a median sale price of approximately $1.95M across roughly 3-6 closings in the prior 90 days. The range runs from $1.5M for village-core homes on 1-2 acres up to $4.5M+ for working agricultural ranches on 20+ acre parcels with established orchards. Days on market average 55, with ranch parcels regularly exceeding 120 days. Inventory is structurally small. Land value, water rights, ag production history, and Williamson Act status drive most of the within-tier variation. Treat all Somis price reads as directional.
Can I have horses and run an avocado or vineyard operation on the same Somis property?
Yes — this is the core Somis value proposition. AE-zoned Somis parcels permit combined agricultural and equestrian use by right. Most working ranches in Somis combine orchards (avocado, citrus) or vineyards (wine grapes) with horse-keeping facilities. Animal-unit counts on AE parcels are essentially unrestricted within water and pasture capacity. Commercial training, boarding, or breeding requires a Conditional Use Permit but the CUP path is well-established with multiple existing operations. The Williamson Act property-tax structure further supports the combined-use model.
What schools serve Somis?
Elementary is Somis School District — a small one-campus K-8 district. The single campus is Somis Elementary School. High school is Camarillo High School under the Oxnard Union High School District, the same high school serving Camarillo proper and most of Santa Rosa Valley. Parcels on the western edge of the Somis area near the Moorpark border may fall inside the Moorpark Unified School District. Verify specific address assignments at somissd.org and oxnardunion.org before tying a purchase decision to a school. I do not steer buyers to or from particular campuses.
Is Somis in a fire zone?
Mixed. Parcels along South Mountain on the southern edge and along the Las Posas Hills on the northern edge sit in CAL FIRE Very High Fire Hazard Severity Zone. Village-core and valley-floor parcels sit in lower-risk zones (Moderate to High FHSZ depending on parcel). Insurance on valley-floor properties typically runs $2,500-$9,000 per year — meaningfully healthier than the LA County equestrian belt. Hillside parcels and parcels with large ag structures face more friction. Confirm specific parcel FHSZ designation at the CAL FIRE viewer before offering.
How is water service handled in Somis?
Water service is split. Many parcels receive municipal water through Ventura County Waterworks District 19. Larger agricultural parcels — particularly working orchards and vineyards — typically combine District 19 connection with private agricultural wells, and well capacity is frequently the limiting factor on parcel productivity. Verify District 19 connection and allocation during escrow, and pull the well report on any parcel with private-well use. Well capacity testing on ag-scale wells should include sustained-pull GPM, lab-panel water quality, and historical pumping record review. Septic is universal — there is no central sewer.
What is the Williamson Act and does it apply to Somis ranches?
The California Land Conservation Act of 1965 (the Williamson Act) allows agricultural landowners to receive reduced property-tax assessment in exchange for a 10-year rolling commitment to keep the land in agricultural use. Williamson Act contracts are common on Somis AE-zoned parcels. The contract carries both the property-tax benefit and a meaningful development restriction. Buying a Williamson Act parcel means accepting the use restriction; exiting requires a 9-year non-renewal process. Understand both sides of the contract before offering on a Williamson Act ranch.
