The Areas · Tarzana · 91356 Tarzana

One boulevard decides which rules apply to you.

Every agent will tell you Tarzana is different north and south of Ventura Boulevard. Almost none can tell you why in terms that affect your purchase. South of the boulevard the land rises into the Santa Monica Mountains, and parcels there commonly fall inside the City’s designated Hillside Area — which triggers a different ordinance governing grading, height and how much house the slope will allow. That is the real divide.

North vs. South of Ventura Baseline Hillside Ordinance Named for Tarzan, 1930 91356

Talk Tarzana With Me Read Its Story First

1919 Edgar Rice Burroughs buys a west Valley ranch from the estate of Gen. Harrison Gray Otis and names it Tarzana Ranch.

1930 Residents vote on the name when a post office is established. Tarzana — after the character — wins.

1973 Providence Cedars-Sinai Tarzana Medical Center is founded, now anchored by the five-story Friese Family Patient Tower.

Mar. 2026 The Ventura-Cahuenga Boulevard Corridor Specific Plan amendment takes effect, updating rules first set in 2001.

The Long Story

A neighborhood named after a fictional character.

Not named for a founder, a saint, or a railroad stop. Tarzana is named for Tarzan, because the man who invented him owned the ranch and the residents voted for it. It is one of the few places in Los Angeles whose name came out of a novel — and the ranch boundary still echoes in how the neighborhood is laid out.

“The boulevard is not a border between neighborhoods. It is a border between rulebooks.”

1919 Burroughs buys the ranch

Author Edgar Rice Burroughs purchased a ranch in the west San Fernando Valley from the estate of General Harrison Gray Otis and named it Tarzana Ranch, after the character who had made him famous. At that point it was agricultural land, not a neighborhood.

1923 Subdivision begins

Burroughs subdivided part of the ranch. The transition from a single holding to a community starts here — and the original ranch footprint is why the area reads differently from the pure grid neighborhoods around it.

1930 The residents vote on a name

When a post office was established, residents chose the name by vote: Tarzana. A community that named itself after a jungle hero is not a place with a shortage of self-confidence.

1973 The hospital arrives

What is now Providence Cedars-Sinai Tarzana Medical Center was founded, a full-service hospital that has since opened the five-story Friese Family Patient Tower with an expanded emergency department, imaging, pediatrics and all-private patient rooms. A major hospital inside the neighborhood is a genuine amenity and a steady local employer.

2018 The medical center leaves the Specific Plan

Ordinance No. 185,650, effective August 12, 2018, removed the Tarzana Medical Center from the Ventura-Cahuenga Boulevard Corridor Specific Plan — a reminder that the rules along the boulevard are not static and are worth checking rather than assuming.

Mar. 24, 2025 New fire hazard maps

CAL FIRE and the Office of the State Fire Marshal released updated Local Responsibility Area maps for the City of Los Angeles. Reporting on the new maps noted that Very High designations now extend north of Ventura Boulevard in parts of the San Fernando Valley — meaning the old shorthand that only the hillside side carries real hazard no longer holds.

Mar. 14, 2026 The corridor plan is amended

The Ventura-Cahuenga Boulevard Corridor Specific Plan amendment took effect, updating the 2001 plan and adding a ministerial Administrative Review path for limited permits — signage, interior tenant improvements, and limited changes of use. If you are buying anything commercial or mixed-use along the boulevard, this is current and directly relevant.

Ground Truth

What locals know that listings don’t say.

South of the boulevard is a different rulebook, not just a different price

South of Ventura the land rises into the Santa Monica Mountains, and parcels there commonly sit inside the City’s designated Hillside Area. That triggers the Baseline Hillside Ordinance, which governs grading, height and slope-density — in plain terms, how much house the land will let you build. Homes south of Ventura Boulevard are among the most expensive in Los Angeles County, and the ordinance is part of why.

Hillside status is a parcel question, not an address impression

Whether a specific property falls inside the Hillside Area is confirmed through LADBS and the city’s ZIMAS parcel system — not by looking at the street or the slope of the driveway. If your plan involves building, remodeling or adding square footage, verify this first. It is the difference between a project that pencils and one that does not.

The old fire shorthand is out of date

The convenient story was always that hillside parcels south of Ventura carry the fire risk and the flats north of it do not. Reporting on the 2025 maps indicates Very High designations now extend north of Ventura Boulevard in parts of the Valley. Whatever you were told before 2025 about this neighborhood needs re-checking at the parcel.

The boulevard has its own specific plan

The commercial corridor through Tarzana is governed by the Ventura-Cahuenga Boulevard Corridor Specific Plan, amended effective March 14, 2026. That amendment added a ministerial Administrative Review path for limited permits. Anyone buying commercial or mixed-use frontage should be reading the current plan, not a summary of the 2001 version.

Tarzana sits in the Encino-Tarzana Community Plan area

The governing community plan pairs Tarzana with Encino. When you are researching what land can become nearby, that is the document to read — and it means Encino’s planning conversation is often Tarzana’s planning conversation too.

The schools span several campuses

Tarzana is served by LAUSD. Tarzana Elementary and Wilbur Charter for Enriched Academics — an LAUSD affiliated charter that opened in 1959 — serve the elementary years; Gaspar de Portola Charter Middle School at 18720 Linnet Street covers grades 6–8; and many Tarzana students attend William Howard Taft Charter High School at Ventura and Winnetka. Attendance boundaries move — verify at the parcel.

The Numbers

How to read the Tarzana market like a local.

Never blend north and south of the boulevard

They are different products under different rules with different buyers. Any average that mixes them describes nothing that exists. When I bring you comparables, they will come from one side of Ventura or the other, and I will tell you which.

On hillside parcels, buildable is the real number

Lot size south of the boulevard can be misleading, because the Baseline Hillside Ordinance limits what the slope will allow. Two similar-sized lots can support very different homes. If your thesis depends on building, price the buildable envelope rather than the acreage.

Re-check the fire zone even if you checked before

The 2025 maps changed the picture, including north of Ventura. A pre-2025 answer about a Tarzana parcel is not a current answer, and insurance quotes will reflect the new maps rather than your memory of the old ones.

Corridor frontage is governed separately

Commercial and mixed-use property along Ventura falls under the corridor specific plan, amended in March 2026. What you can do with a storefront is a plan question before it is a market question.

Why I Know This Place

My office is minutes down the boulevard.

I work out of Rodeo Realty on Ventura Boulevard in Woodland Hills, a short drive west of Tarzana on the same street. This is the corridor I drive most, and the boulevard’s split personality — flats on one side, mountains on the other — is something I deal with in practice rather than in theory.

What I bring here is not childhood nostalgia; I grew up in Chatsworth, at the other end of the Valley. It is the habit of checking which ordinance governs a parcel before I tell anyone what it is worth. In Tarzana, where one street can put you under a different rulebook, that habit is the whole job.

Next Door

Tarzana sits against the areas I know best.

Encino East along the boulevard, and its partner in the shared Encino-Tarzana Community Plan. Woodland Hills West along Ventura — where my office sits, and a market I work constantly. Calabasas Further west into the hills, where the whole city sits in a Very High fire hazard zone.

One Honest Conversation

The homeowner brief

What I actually know about Tarzana.

The boulevard, the ordinances on either side of it, and the details that decide what a parcel here can actually become.

The name came out of a novel

Edgar Rice Burroughs bought a west San Fernando Valley ranch in 1919 from the estate of General Harrison Gray Otis and named it Tarzana Ranch, after the character who made him famous. He subdivided part of it in 1923, and when a post office was established in 1930 the residents voted on the community’s name. Tarzana won.

Ventura Boulevard divides two rulebooks

South of the boulevard the land rises into the Santa Monica Mountains, and parcels there commonly sit inside the City’s designated Hillside Area — which triggers the Baseline Hillside Ordinance governing grading, height and slope-density. Homes south of Ventura Boulevard are among the most expensive in Los Angeles County. The divide is not just prestige; it is which regulations apply to you.

Hillside status is verified at the parcel

Whether a specific property falls inside the Hillside Area is confirmed through LADBS and the city’s ZIMAS parcel system, not by looking at the terrain. If your plan involves building, remodeling or adding square footage, verify this before you write the offer — it can decide whether a project is feasible at all.

The corridor plan was amended in 2026

The commercial corridor is governed by the Ventura-Cahuenga Boulevard Corridor Specific Plan. An amendment took effect March 14, 2026, updating the 2001 plan and adding a ministerial Administrative Review path for limited permits — signage, interior tenant improvements, and limited changes of use. Separately, Ordinance No. 185,650, effective August 12, 2018, removed the Tarzana Medical Center from the Specific Plan.

The schools, by name

Tarzana is served by Los Angeles Unified. Tarzana Elementary and Wilbur Charter for Enriched Academics — an LAUSD affiliated charter that opened in 1959 — serve elementary; Gaspar de Portola Charter Middle School at 18720 Linnet Street covers grades 6–8; and many students attend William Howard Taft Charter High School at Ventura and Winnetka. Attendance boundaries move, so verify at the specific parcel.

A full hospital inside the neighborhood

Providence Cedars-Sinai Tarzana Medical Center, founded in 1973, is a full-service hospital anchored by the five-story Friese Family Patient Tower with an expanded emergency department, imaging, pediatrics and all-private patient rooms. For buyers weighing proximity to care — and for the local employment base — that is a material feature of this neighborhood.

Straight answers

Fire zones and insurance: the straight version.

The comfortable old story about Tarzana and fire risk stopped being accurate in 2025. Here is what changed, and how to get a real answer for a specific address.

“It’s north of Ventura, so it’s fine” is no longer a safe assumption.

The convenient shorthand was always that hillside parcels south of Ventura Boulevard carry the wildfire exposure and the flats north of it do not. Reporting on the March 2025 CAL FIRE maps indicates Very High fire hazard severity now extends north of Ventura Boulevard in parts of the San Fernando Valley. Designations are mapped parcel by parcel regardless, so look the specific address up on the CAL FIRE / Office of the State Fire Marshal viewer and confirm against the LAFD Fire Zone Map and ZIMAS. If you last checked before 2025, check again.

Three tiers where there used to be one

The 2025 Local Responsibility Area maps, released March 24, 2025 for the City of Los Angeles, classify land as Moderate, High or Very High. Earlier LRA maps mapped only Very High, so Moderate and High are categories that did not previously exist inside city limits. A parcel newly showing Moderate has not been downgraded — it has been placed in a category that is new.

A city can raise a zone, never lower it

State law lets a local agency increase a state-recommended hazard level but not decrease it, and Los Angeles is required to adopt the recommended maps by ordinance. LAFD has been aligning the state map boundaries to city streets and parcel lines ahead of public review, so confirm the current adopted status rather than assuming.

What a Very High or High designation triggers

Buildings in those zones must comply with the California Wildland-Urban Interface Code as amended by Los Angeles Municipal Code Chapter V, Article 7.1, with additional obligations under LAMC section 57.4911. These are construction and maintenance requirements with real cost attached.

Brush clearance is year-round, and wider than people expect

In a Very High zone the LAFD requires year-round maintenance of hazardous vegetation within 200 feet of structures, and within 10 feet of combustible fences and driveways. Inspections run in May and June. On a hillside parcel south of the boulevard, that maintenance obligation is a real annual cost worth pricing before you buy.

Defensible space is already the law

California Public Resources Code 4291 requires 100 feet of defensible space around structures in these areas. That one is in effect now, and it is the first thing an insurer's inspector looks at.

“Zone 0” is coming, but is not law yet

The proposed ember-resistant zone — the first five feet around a house, kept clear of anything that burns — was created by AB 3074 in 2020 and reshaped by SB 504 (2024), AB 1455 (2025) and Executive Order N-18-25. The Board of Forestry's April 17, 2026 draft proposes phased implementation and is still a draft. Anyone telling you Zone 0 is already mandatory statewide is ahead of the record.

The FAIR Plan is a backstop, not a bargain

It is an involuntary pool shared by every insurer licensed to write basic property insurance in California — not a state agency, and not funded by taxpayers. Its residential exposure grew 424% between September 2020 and June 2025, reaching $603 billion, with roughly 573,700 policies in force as of March 2025. It is the insurer of last resort, and it is priced like it.

The rules for insurers changed too

Under the Department of Insurance's Sustainable Insurance Strategy, the wildfire catastrophe-modeling regulation was announced December 13, 2024, with reinsurance and ratemaking regulations submitted for approval December 30, 2024. Insurers gained the ability to use catastrophe models in setting rates in exchange for commitments to write in distressed wildfire areas.

Common questions

Tarzana, answered.

What is the real difference between north and south of Ventura Boulevard in Tarzana?

Price is the visible difference — homes south of Ventura Boulevard are among the most expensive in Los Angeles County. The structural difference is regulatory. South of the boulevard the land rises into the Santa Monica Mountains and parcels there commonly fall inside the City’s designated Hillside Area, which triggers the Baseline Hillside Ordinance governing grading, height and slope-density. That ordinance determines how much house the land will actually support, which is why two similar-sized lots can be worth very different amounts.

Is my Tarzana property in the Hillside Area?

That is verified at the parcel through LADBS and the city’s ZIMAS system, not by looking at the slope of the street. It matters most if you intend to build, remodel or add square footage, because the Baseline Hillside Ordinance can materially limit what is possible. Confirm it before removing contingencies rather than after.

What fire hazard severity zone is Tarzana in?

There is no single answer for the neighborhood, and the old shorthand is now unreliable. Reporting on the March 24, 2025 CAL FIRE maps indicates Very High designations now extend north of Ventura Boulevard in parts of the Valley, so the assumption that only the hillside side carries hazard no longer holds. Zones are mapped parcel by parcel — look the address up on the CAL FIRE / Office of the State Fire Marshal viewer and confirm against the LAFD Fire Zone Map and ZIMAS.

Why is it called Tarzana?

Because Edgar Rice Burroughs, who created Tarzan, bought a ranch here in 1919 from the estate of General Harrison Gray Otis and named it Tarzana Ranch. He subdivided part of it in 1923, and when a post office was established in 1930 residents chose the community’s name by vote.

What ZIP code is Tarzana?

91356 is the primary ZIP. Because ZIP boundaries and neighborhood boundaries are drawn for different purposes, treat any ZIP-level market statistic with care and ask which properties are actually in the set — particularly given how differently the north and south sides of Ventura Boulevard behave.

What schools serve Tarzana?

Los Angeles Unified. Tarzana Elementary and Wilbur Charter for Enriched Academics, an LAUSD affiliated charter opened in 1959, serve the elementary years. Gaspar de Portola Charter Middle School at 18720 Linnet Street covers grades 6–8, and many Tarzana students attend William Howard Taft Charter High School at Ventura and Winnetka. Attendance boundaries change — verify at the specific parcel before relying on any assignment.

I’m buying commercial space on Ventura Boulevard. What governs it?

The Ventura-Cahuenga Boulevard Corridor Specific Plan. An amendment took effect March 14, 2026 that updated the 2001 plan and added a ministerial Administrative Review path for limited permits, including signage, interior tenant improvements and limited changes of use. Read the current amended plan rather than a summary of the older version, because what you may do with a storefront is a planning question before it is a market question.
