Buying a Home in Ventura County, CA: Transfer Tax, Wildfire Zones & Coastal Permits

From Pacific coastline to fire-prone hillside towns, Ventura County's rules shift sharply depending on exactly where a property sits.

Ventura County stretches from the Oxnard Plain and a genuine Pacific coastline through inland cities (Camarillo, Moorpark, Simi Valley, Thousand Oaks) to fire-prone hillside communities like Ojai and Santa Paula — three different regulatory regimes a buyer needs to know depending on where in the county a property sits.

What’s the transfer tax in Ventura County?

Ventura County's rate is flat across the entire county at $1.10 per $1,000 of consideration, with no city imposing an additional surcharge on top.

Every incorporated Ventura County city (Camarillo, Fillmore, Moorpark, Ojai, Oxnard, Port Hueneme, San Buenaventura, Santa Paula, Simi Valley, Thousand Oaks) sits at the standard $0.55 county + $0.55 city split, for the same $1.10/$1,000 total. On a $700,000 sale, that's $770 in transfer tax anywhere in the county.

How much wildfire risk is there in Ventura County?

It's expanding fast — CAL FIRE's 2025 remap significantly grew the county's mapped fire hazard zones, and in Ojai specifically the very-high-hazard acreage more than tripled, concentrated along the northern coast and inland between Santa Paula and Ojai.

Buyers in these zones increasingly need to plan for the California FAIR Plan paired with a Difference-in-Conditions (DIC) policy, or a surplus-lines carrier, rather than assuming a standard admitted carrier will write a policy. Since July 1, 2021, California law requires the seller to document a compliant Defensible Space Inspection when selling a property in a mapped high or very-high Fire Hazard Severity Zone. Get an actual insurance quote — not just a defensible-space inspection — during your contingency period before writing an offer in one of these zones.

Do I need a Coastal Development Permit in Ventura County?

Likely yes for a coastal property — a meaningful share of the county sits inside the California Coastal Zone, governed by the county's own Local Coastal Program and Coastal Zoning Ordinance for unincorporated areas.

Most development in this zone — including many remodels and additions — requires a Coastal Development Permit (CDP) in addition to a standard local building permit, and in some areas the California Coastal Commission itself retains direct permit authority rather than the county. Get a coastal land-use read on a specific renovation before your offer is accepted; the South Central Coast District office (covering both Ventura and Santa Barbara counties) is the Commission's point of contact here.

Which Ventura County developments have Mello-Roos?

Many newer neighborhoods — including areas near the Simi Valley border and recently built subdivisions in Camarillo and Moorpark — carry Mello-Roos Community Facilities District special taxes; an older, established-neighborhood home typically does not.

These special taxes fund roads, parks, schools, and public safety infrastructure tied to the development, and annual amounts vary widely by district. California Civil Code §1102.6b requires the seller to make a good-faith effort to obtain and deliver a Notice of Special Tax before close — confirm CFD status directly rather than assuming based on a neighboring home.

Is there rent control in Ventura County?

Two real exceptions: Oxnard's Rent Stabilization ordinance caps annual increases at 4% for multifamily property built before February 1, 1995, and Ojai's Ordinance No. 937 (2023) caps annual increases at 4% for most rentals — both well beyond the statewide AB 1482 floor.

Oxnard's ordinance also requires just-cause eviction after 30 days of tenancy, with a no-fault eviction requiring relocation assistance of two months' rent or $5,000, whichever is greater. Ojai's ordinance permits only one increase per 12-month period, with a landlord petition process for fair-return increases above the cap (Ojai Municipal Code §11-1.08, §11-1.16). Separately, five of the county's ten cities (Santa Paula, Thousand Oaks, Ventura, Oxnard, Moorpark) have narrower mobile-home-park-only rent stabilization ordinances. If you're buying a pre-1995 Oxnard multifamily or an Ojai rental property with existing tenants, you inherit the applicable rent cap and just-cause obligations — confirm construction date and tenancy status before assuming full control after close.

Frequently asked

Does Oxnard or Ventura have a city transfer tax on top of the county rate?

No. Every Ventura County city sits at the same flat $1.10 per $1,000 combined rate — no city-level surcharge anywhere in the county.

How do I find out if a Ventura County home is in a high fire hazard zone?

Check the current CAL FIRE Fire Hazard Severity Zone maps for the specific address — the 2025 remap significantly expanded coverage, especially around Ojai and Santa Paula — and get an actual insurance quote during your contingency period rather than assuming standard coverage will be available.

Is Oxnard rent control the same as the mobile-home ordinances in other Ventura County cities?

No — Oxnard's and Ojai's ordinances cover general residential rentals (Oxnard: multifamily built before February 1, 1995; Ojai: most rentals, capped at 4%). Santa Paula, Thousand Oaks, Ventura, and Moorpark's ordinances apply only to mobile-home park space rent, a narrower protection.
