Westlake Village vs Calabasas: What You Actually Pay for the Zip Code

The Westlake Village vs Calabasas question usually arrives as a price question, and the honest answer is that the two cities cost almost the same per square foot. Calabasas sold at a median $683 per square foot in the second quarter of 2025; Westlake Village sold at $696 in the same quarter. The real differences are county lines, tax bills, school boundaries and how much house you get for the money. That is where this comparison belongs.

Is Westlake Village in Los Angeles County or Ventura County?

Both, and that is the single most misunderstood fact in this market. The City of Westlake Village incorporated on December 11, 1981, as the 82nd municipality in Los Angeles County. It covers about 5.4 square miles at roughly 900 feet of elevation, nine miles inland from the Pacific and 38 miles west of downtown LA, framed by the Simi Hills to the north and the Santa Monica Mountains to the south, per the city's own history page. The 2020 census counted 8,029 residents.

The master planned community around the lake is much larger than the city. In 1968 and 1972, roughly 8,544 acres on the Ventura County side were annexed into Thousand Oaks, and only the remaining LA County third later incorporated. Those Thousand Oaks homes still carry Westlake Village mailing addresses and share the 91361 and 91362 ZIP codes with the city, so a zip code alone tells you almost nothing about which city or county you are buying into. I cover the mechanics of this in detail in my guide to the community that straddles two counties, and the practical tradeoffs in my Westlake Village and Thousand Oaks comparison.

Calabasas is simpler. It incorporated on April 5, 1991, sits entirely in LA County in the hills west of the San Fernando Valley between Woodland Hills, Agoura Hills, West Hills, Hidden Hills and Malibu, and covers 13.71 square miles with a 2020 population of 23,241 and 9,289 housing units, according to the Los Angeles Almanac. In plain terms, Calabasas is about 2.5 times the land area and nearly three times the population of the City of Westlake Village.

How do Calabasas home prices compare to Westlake Village real estate?

Calabasas home prices landed at a $1.7 million median in the second quarter of 2025, down 4.5% year over year, on 74 sales, up 13.8% from the prior year, per PropertyShark. That is nearly double the $900,000 LA County median and places Calabasas tenth among county cities at $1,737,500, just behind Rolling Hills Estates and just ahead of Santa Monica. Sellers in the 91302 ZIP code who closed in the third quarter had gained just over 59% over their holding period, compared with about 50% countywide, a median gain of $635,000, as The Real Deal reported.

Westlake Village real estate is harder to summarize because the community spans two counties and two cities. The cleanest apples to apples figure is price per square foot: $696 in the second quarter of 2025 and $662 in the fourth quarter, against a Ventura County median that ran between $839,000 and $865,000 across the four quarters of 2025, per the same source. The lakefront, Westlake Island and North Ranch sit well above those figures; my luxury enclave guide breaks down how each one prices.

Median home value, income, age and commute figures come from U.S. News profiles of Westlake Village and Calabasas; population figures reflect the 2020 U.S. Census. Note the pattern: Westlake Village households earn more and commute less, yet Calabasas carries the higher median value because its housing stock skews larger and more gated.

What do you actually pay in property tax and sales tax in Westlake Village vs Calabasas?

Property tax starts in the same place in both cities: roughly 1% of assessed value under Proposition 13, plus voter approved bonds. In Calabasas, the median effective rate works out to 1.21% of assessed market value, based on LA County records compiled by Ownwell. On a $1.7 million purchase, that is about $20,570 a year before any special charges. Verify the parcel itself through the LA County Assessor or, for Thousand Oaks addressed homes, the Ventura County Assessor.

Mello-Roos is the line item that surprises people. It is a special tax levied through a Community Facilities District, a financing tool California created in 1982 to fund roads, sewers and similar infrastructure in new developments. Most established Calabasas neighborhoods do not carry it, but some newer tracts, gated communities and condo projects do, alongside HOA dues. The rule I give every client: listing sheets quote the base rate, so request the current secured property tax bill during escrow and read every line.

Sales tax is where the county line shows up on a receipt. The rate table in effect from January through March 2025 listed Calabasas at 9.500%, Westlake Village at 9.500% and Thousand Oaks at 7.250%, per the California Department of Tax and Fee Administration. A Westlake Village address inside Thousand Oaks city limits pays the lower Ventura County rate. Carrying costs matter more than most buyers expect when rates are elevated, which is why I have been telling clients not to wait on 5% mortgages.

How do Las Virgenes schools factor into the price?

Las Virgenes Unified School District is headquartered in Calabasas and serves K through 12. Niche ranks it #48 among California school districts with an overall A grade and a 4.44 out of 5 parent and student rating. The district graduates 95% of its students, according to U.S. News, with 70% of elementary students proficient in reading and 63% in math.

The 2024 state results were more mixed than the reputation suggests: 69.7% of students met standards in English and 58.6% in math, and 11th grade math proficiency fell to 45.8%. Those are strong numbers in a statewide context, and they are worth knowing when a listing agent leans on the school name to justify price.

The buyer trap is boundaries. Because Westlake Village addresses span two counties and two cities, the ZIP code does not tell you which district serves a given home. Confirm the exact attendance area for the parcel before you write, not after. My neighborhood by neighborhood guide maps this out street by street.

Which is the better buy, Westlake Village or Calabasas?

If you want the most house per dollar, the per square foot figures say it is essentially a tie, so choose on lifestyle and logistics. Calabasas offers a larger city, a younger median age of 45.2, a bigger pool of gated estate communities, and a 30 minute average commute pointed toward the Valley and Westside. Westlake Village offers the lake, a 22 minute average commute, a higher median household income, and the option to live on the Ventura County side with a lower sales tax rate. Neither has a true zip code premium; what you pay for is lot size, gates, views and water.

Before touring either, read what I wish every buyer knew before starting their search. The county line conversation alone has saved clients from the wrong escrow more than once.
