Notable: Ventura Harbor Village; Oxnard Beach; Camarillo Premium Outlets; Ojai Art Center
Notes: Ventura County’s Channel Islands are one of California’s most extraordinary and underappreciated natural treasures; the islands’ isolation has allowed the evolution of endemic species and the recovery of others (the island fox – one of the world’s rarest mammals – was critically endangered in 2000 and has recovered to over 7,000 animals through an intensive breeding and reintroduction program); Channel Islands NP’s kelp forest diving is world-class; Ojai’s spiritual and artistic community (the valley was long associated with Jiddu Krishnamurti; its “Pink Moment” sunset phenomenon draws visitors specifically to witness the alpenglow on the Topa Topa Mountains) makes it unique among California communities; the Ronald Reagan Presidential Library’s Air Force One exhibit (the actual plane used by Reagan and subsequent presidents) is one of the most impressive presidential library exhibits in the US

Notes: The Thomas Fire’s relationship to the Montecito (Santa Barbara County) debris flow (the fire burned the watershed bare; a January 2018 storm sent rivers of mud and boulders down into Montecito killing 23 people) was a pivotal moment in California’s understanding of post-fire debris flow risk; the Ventura County Watershed Protection District has significantly enhanced post-fire debris flow monitoring and early warning systems; Oxnard Plain’s agricultural productivity (strawberries, citrus, avocados, celery – the Oxnard Plain is one of California’s most productive agricultural areas thanks to mild coastal climate) requires careful management of water resources and pesticide use; Casitas Municipal Water District’s Lake Casitas (which was the county’s primary water storage reservoir) has been severely affected by drought – during the drought years the lake’s level dropped to critically low levels, and the lake is now being replenished; Point Mugu NAS’s PFAS contamination is one of the most significant environmental remediation projects in Ventura County – the contamination plume has affected Oxnard groundwater; Channel Islands’ invasive species removal (pigs, golden eagles, fennel) has been a major conservation program enabling island fox recovery; the Santa Barbara Channel blue whale feeding aggregations (some of the largest concentrations of blue whales in the world occur here in summer) are affected by ship strikes – vessel speed reduction programs have been implemented by NOAA to protect blue whales
About Ventura County
Ventura County occupies a 1,845-square-mile coastal and inland swath between Los Angeles County to the south and east and Santa Barbara County to the north – close enough to LA to function as a commuter county for many residents, yet distinct in character. The county seat is the City of Ventura (officially San Buenaventura), a coastal city of about 110,000 on the Santa Barbara Channel. Other major communities include Oxnard (the county’s largest city), Thousand Oaks, Simi Valley, Camarillo, Moorpark, Fillmore, and Santa Paula. The county has a strong agricultural heritage – strawberries, citrus, avocados, and lemons – alongside significant defense and tech employment at Naval Base Ventura County and in the Thousand Oaks corridor.
County government is a five-member Board of Supervisors with a County Executive Officer, and independently elected offices for the Sheriff, District Attorney, Assessor, Auditor-Controller, Treasurer-Tax Collector, and Clerk of the Board. Ventura County has no incorporated county seat in the traditional sense – the county’s administrative center at 800 S. Victoria Avenue in the City of Ventura houses most county offices.

California property tax is governed by Proposition 13 (1978): the base rate is 1% of assessed value, capped at a maximum 2% annual increase in assessed value. Assessed value is set at the purchase price (base year value) and increases no more than 2% per year – regardless of market appreciation – unless a change of ownership or new construction triggers a reassessment to current market value. Local voter-approved bonds and special district levies add to the 1% base; Ventura County’s total effective rate typically runs 1.10–1.15% depending on location.
Proposition 19 (2021) significantly changed family property tax transfers. Parent-to-child transfers of a primary residence no longer automatically preserve the parent’s base year value – the child must use the property as their primary residence, and the exclusion is capped at $1 million of value above the assessed value. Estate planners and families considering property transfers should verify current Prop 19 implications.
Decline-in-value (Prop 8) applications: When the current market value of a property falls below the Prop 13 assessed value, owners may file a Prop 8 application requesting a temporary reduction. File between July 2 and November 30 annually with the Ventura County Assessor.
Regular assessment appeal window: July 2 through September 15 each year (for the January 1 assessment). File an Assessment Appeal Application online at venturacounty.gov/oaa, or in person at the Clerk of the Board, 800 S. Victoria Avenue, 4th Floor, Ventura. The Assessment Appeals Board or Hearing Officer conducts hearings – both parties present evidence at an open public meeting. Hearings are not informal conversations; come prepared with comparable sales, appraisals, or documented property record errors.
Supplemental and escape assessments (triggered by ownership change or new construction) must be appealed within 60 days of the mailing date on the notice.
Tax bills are due November 1 (first installment) and February 1 (second installment), delinquent after December 10 and April 10. The California Homeowner’s Exemption reduces assessed value by $7,000 – apply once with the Assessor; it renews automatically.
Prop 19 base year transfer for seniors: Qualifying homeowners 55 or older may transfer their base year value to a replacement home of any price anywhere in California – up to three times. This is one of the most powerful senior tax benefits in California for those considering downsizing or relocating.
OWNWELL CTA: Ventura County’s regular appeal window is July 2–September 15. Supplemental and escape assessment appeals must be filed within 60 days of notice. Prop 19 has changed the family transfer calculus. Ownwell manages the appeal process with no upfront cost.

Courts & Legal
Courts & Legal
The Ventura County Superior Court at 800 S. Victoria Avenue, Ventura (805-289-8900) is the trial court for all civil, criminal, family, and probate matters in the county. The Probate Division handles wills, estates, guardianships, conservatorships, and trusts – mandatory electronic filing has been in effect since May 5, 2025. The Ventura County Assessor (805-654-2181) and Recorder (805-654-2263) maintain property records and land documents at 800 S. Victoria Avenue. Records are searchable online.
California probate is governed by the California Probate Code. California has no state estate tax and no inheritance tax – only the federal estate tax applies above the current threshold. Prop 19 significantly changed how real property passes through families – the old broad parent-child base year value exclusion has been substantially curtailed. Estate planning in Ventura County should specifically address Prop 19 implications for any real property intended to pass to heirs.
Senior Services: The Area Agency on Aging – Ventura County (805-477-7300) coordinates senior programming, home-delivered meals, transportation, HICAP (Health Insurance Counseling and Advocacy Program) Medicare counseling, and connections to California’s Medi-Cal long-term care programs. The IHSS (In-Home Supportive Services) program, administered at the county level, provides Medi-Cal-funded in-home care for qualifying seniors and disabled residents.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go

Ventura County also operates courthouses in Simi Valley (East County) and Oxnard (Juvenile) – probate matters are generally handled at the main Ventura location.
Step 1: figure out which path applies
California recently increased its small-estate thresholds substantially, so check this first – more estates now qualify to skip full probate than in past years.
Small Estate Affidavit (personal property) – for estates with personal property valued at $208,850 or less (for deaths on or after April 1, 2025; holds through March 31, 2028). No court filing needed – present the signed affidavit directly to the bank or institution holding the property. Must wait at least 40 days after the death, and no probate proceeding can already be pending.
Petition to Determine Succession to Real Property, Primary Residence – for a decedent’s primary California residence valued at $750,000 or less (Judicial Council Form DE-310). Requires a 40-day wait, notice to heirs, and a probate referee appraisal.
Affidavit for Real Property of Small Value – for other (non-primary-residence) California real property valued at $69,625 or less (Form DE-305). Requires a 6-month wait.
Formal Probate – required when the estate exceeds these thresholds. California typically uses the Independent Administration of Estates Act (IAEA), letting the personal representative handle most matters without a court hearing for each step.
California is a community property state – a surviving spouse already owns their half of community property, and can often use a simplified Spousal Property Petition (Form DE-221) instead.
If using the small estate affidavit (personal property)
Wait at least 40 days after the death.
Confirm total qualifying California personal property (excluding trust assets, joint tenancy, POD/TOD accounts, and beneficiary-designated accounts) is $208,850 or less, using date-of-death values.
Complete the affidavit under Probate Code § 13100.
Present it with a certified death certificate directly to the bank or institution – no court filing required. Collecting property this way makes you personally liable for the decedent’s unsecured debts up to the value received (Prob. Code § 13109).
IF USING THE PRIMARY RESIDENCE PETITION OR SMALL REAL PROPERTY AFFIDAVIT
Confirm the property qualifies and the applicable waiting period has passed (40 days for the primary-residence petition; 6 months for the small real property affidavit).
File the petition (Form DE-310) or affidavit (Form DE-305) with the Ventura County Superior Court.
A probate referee appraises the property; heirs receive notice.
Once approved, the property transfers without full probate administration.
If formal probate is required
Deliver the original will (if any) to the court clerk within 30 days of learning of the death (Prob. Code § 8200).
File a Petition for Probate (Form DE-111) to admit the will and request appointment as personal representative.
The court issues Letters Testamentary (Form DE-150) or Letters of Administration.
If Independent Administration authority is granted, the personal representative can act on most matters without separate court hearings.
Notice to creditors and an inventory/appraisal (with a probate referee) follow, along with payment of debts and taxes.
The estate closes with a final petition for distribution.
What it costs
Small estate affidavit / real property affidavits: no court filing fee for the personal-property affidavit; filing fees apply to the DE-310 primary-residence petition and DE-305 small real property affidavit.
Formal probate filing fee: several hundred dollars, varying somewhat by county.
Personal representative and attorney compensation: statutory fee schedule based on estate size (Prob. Code §§ 10800–10810) – a percentage that declines as the estate grows.
No California state estate tax or inheritance tax.
