Remodeling in Tarzana: What to Know
Tarzana is really three remodel markets in one ZIP code. South of Ventura Boulevard, hillside lots fall under LA's Baseline Hillside Ordinance — geotechnical review, tighter grading rules, and sewer laterals that can run 100–200 feet. North of the boulevard, postwar ranch tracts carry the standard 1950s package behind the walls. And Melody Acres, the equestrian pocket, is zoned RA with 17,500-square-foot minimum lots and its own setback rules for barns and corrals. Permits for all three go through LADBS.
Tarzana is the only neighborhood in Los Angeles named after a fictional ape-man, and the origin story still shapes what remodeling here looks like. In 1919 Edgar Rice Burroughs bought a 540-acre ranch from the estate of Harrison Gray Otis and named it Tarzana Ranch after his best-selling creation. He began subdividing in 1923, and the tract grew into the neighborhood that runs from the Santa Monica Mountains down across the Valley floor.
That history left behind not one housing market but three — and each remodels differently.
South of the Boulevard: the hillside
The old heart of the Burroughs ranch climbs from Ventura Boulevard toward Mulholland, and today it holds Tarzana's estate section — winding streets, big lots, gated pockets, and houses from every decade since the 1930s.
Almost all of it sits in the City of LA's designated Hillside Area, which means the Baseline Hillside Ordinance governs what you can build: floor-area limits tied to slope, grading caps, geotechnical review for new foundation work, and haul-route approval when serious dirt has to move. None of this is a reason not to remodel — but it is why a hillside bid carries line items a flatland bid does not, a list we cover in what nobody budgets for on hillside lots.
The other hillside signature is invisible: distance. Large lots and deep setbacks mean sewer laterals commonly run 100–200 feet from house to main — much of it original clay pipe with a joint every few feet, under mature landscaping that roots straight into them. On a lateral that long, the trenchless-versus-dig decision swings tens of thousands of dollars, which is exactly the math in our sewer line replacement guide. A camera inspection belongs at the top of any south-of-the-Boulevard remodel checklist.
Many of these streets also sit in a mapped fire-hazard zone, so reroofs and additions pick up Chapter 7A fire-rated assembly requirements — worth checking your address before pricing anything exterior.
North of the Boulevard: the postwar flats
Between Ventura Boulevard and Victory, Tarzana looks like the rest of the central Valley: one-story ranch tracts built in the late 1940s through the 1960s on flat, regular lots. These are the easiest houses in the neighborhood to remodel — conventional framing, crawl-space foundations on the older streets, no hillside review.
What they hide is the standard postwar package: 100-amp panels that stall at the first EV charger or induction range, galvanized supply pipes at the end of their life, and undersized ducts or none at all. We wrote up the full list in what's behind the walls of a 1950s Valley house — Tarzana's flats match it almost house for house. Budget the systems first, finishes second.
Melody Acres: the Valley that time kept
Tucked between Wilbur and Lindley south of Oxnard sits Melody Acres — about 320 homes zoned RA (residential agriculture) with a 17,500-square-foot minimum lot size. Horses, chickens, fruit trees, and the occasional donkey are not only tolerated but the whole point.
For remodeling, those big lots are an opportunity: room for substantial additions and detached ADUs without crowding the lot — the kind of project on our additions and ADUs page. Two cautions, though. Animal structures carry their own setback rules from property lines and neighboring dwellings, so a barn or corral is a permit conversation, not a weekend project. And the semi-rural character is precisely what the market pays for here — a design that suburbanizes the lot works against the street.
The practical notes
Tarzana is City of Los Angeles, so everything permits through LADBS — the Van Nuys office at 6262 Van Nuys Blvd is the working counter for the Valley. The commercial frontage on Ventura Boulevard falls under the Ventura-Cahuenga Boulevard Corridor Specific Plan, which matters if your project touches a storefront or mixed-use building. And Tarzana's mature oaks are protected under LA's native tree ordinance — removal or heavy trimming near construction needs a permit, and the fines for skipping it are real.
Three markets, one neighborhood, one building department. Know which Tarzana you are in before you budget, and the rest follows.
Questions
Which building department covers Tarzana?
Tarzana is City of Los Angeles, so permits go through LADBS — the Van Nuys office at 6262 Van Nuys Blvd is the closest counter. Unlike Burbank or Glendale, which run their own building departments, everything here follows LA's zoning code, hillside rules, and plan-check queue.
What is special about remodeling in Melody Acres?
Melody Acres is zoned RA (residential agriculture) with a 17,500-square-foot minimum lot size, which is why the neighborhood of roughly 320 homes still keeps horses, chickens, and orchards. For a remodel that means room for generous additions and ADUs, but animal structures — barns, corrals, coops — carry their own setback requirements, and buyers pay for the semi-rural character, so protect it in the design.
Do hillside remodels south of Ventura really cost more?
Yes, predictably so. Lots in the Hillside Area trigger the Baseline Hillside Ordinance — slope-based limits on size and grading, geotechnical reports for foundation work, and haul-route logistics for anything involving dirt. Add long driveways and 100-plus-foot sewer laterals on older clay pipe, and the same scope of work simply carries more engineering than a flatland job.
