Design in Encino
Two very different markets divided by Ventura Boulevard — half-acre flat lots to the north, hillside parcels to the south. The ordinance that governs your project depends on which side you are on.
Ventura Boulevard is the dividing line.
Encino is part of the City of Los Angeles, so projects here go through LA City Planning and LADBS rather than a local city hall — and that means LA's citywide ordinances apply in full. Which of them governs your project depends almost entirely on which side of Ventura Boulevard your lot sits on.
North of the Boulevard are the flats: Amestoy Estates, Encino Park, Royal Oaks and the surrounding streets, with generously sized, largely level lots — half an acre and up in the better pockets, some with legacy horsekeeping rights. Here the binding constraint is the Baseline Mansionization Ordinance, which caps how much floor area a flat lot may carry and regulates the form that area takes.
South of the Boulevard, the land climbs into the Encino Hills and the Baseline Hillside Ordinance takes over. It is a fundamentally different instrument: buildable floor area is tied to lot slope, grading quantities are capped, height is measured against natural grade, and export above certain thresholds can trigger haul route approval — a discretionary process with a public hearing that is frequently the single largest variable in a hillside project's timeline.
Both sides share LA's protected tree ordinance, and the hills carry fire-zone construction requirements. What they do not share is a design approach, which is why the first question we ask about an Encino project is the address.
What actually governs your lot.
The difference between a flat Encino lot and a hillside one is not a matter of degree — it is a different ordinance, a different feasibility study and a different risk profile. Confirm current standards with LA City Planning before relying on any of this; the ordinances are amended.
South of Ventura: slope decides the house
Under the Baseline Hillside Ordinance, the floor area you may build is a function of the lot's average slope — steeper lots yield less — with further limits on grading quantity, height above natural grade, and retaining. The honest implication is that two same-sized lots a block apart can support very different houses, and that a design conceived before the slope analysis is a design likely to be cut. We run the slope and buildable-area study first and present massing options against it, so the program is set by what is achievable rather than discovered to be impossible at plan check.
Haul routes are the hidden schedule risk
Significant hillside grading means exporting soil, and export above the applicable threshold requires haul route approval — a discretionary review with a public hearing, neighbor notification and conditions on truck routing and hours. It is the step most likely to add months to a hillside project, and it is sensitive to how much dirt you move. Designing to work with the existing grade rather than against it is therefore not only cheaper to build, it is often materially faster to approve.
North of Ventura: floor area, and the shape it takes
On the flats, the Baseline Mansionization Ordinance governs how much floor area a lot may carry and shapes the envelope — encouraging articulation and setback rather than a single maximised box. On an Amestoy Estates or Royal Oaks lot, where the land is generous and the existing houses are often modest post-war ranches, the design question is usually how to use the allowance well: single-storey spread versus two-storey compactness, where to put the volume, how much to give to the garden. We model the options at full scale so the trade-off is visible rather than theoretical.
Protected trees, on both sides of the line
Los Angeles protects native oak, Western sycamore, California bay and toyon above specified sizes. Removal or encroachment requires a permit, an arborist's report and replacement planting, and the protected zone extends well beyond the trunk. On the larger Encino lots these are frequently the most valuable thing on the property, and designing around a mature sycamore almost always produces a better house than removing it would have. We locate and model them before the footprint is set.

Common questions about designing in Encino.
How much can I build on an Encino hillside lot?
South of Ventura Boulevard the Baseline Hillside Ordinance ties maximum floor area to the lot's average slope, so the answer is specific to your parcel — steeper lots yield less, and grading, height above natural grade and retaining are capped alongside. Two similar-looking lots on the same street can support meaningfully different houses. The first thing we do on a hillside project is the slope and buildable-area analysis; everything else follows from it. Confirm current standards with LA City Planning, as the ordinance is amended.
What is a haul route approval and will I need one?
If your project exports soil above the applicable threshold — which significant hillside grading usually does — you need discretionary approval for the truck route, involving a public hearing, neighbor notification and conditions on routing and hours. It is the step most likely to add months to a hillside schedule. Designing with the existing grade rather than cutting a large pad is the most reliable way to reduce or avoid it.
Is Encino governed by the City of Los Angeles?
Yes. Unlike Calabasas or Hidden Hills, Encino is a neighborhood of the City of Los Angeles, so projects go through LA City Planning and LADBS and LA's citywide ordinances apply — the Baseline Hillside Ordinance in hillside areas, the Baseline Mansionization Ordinance on flat lots, and the protected tree ordinance throughout.
What is the difference between building north and south of Ventura Boulevard?
Practically everything about the constraint set. North of the Boulevard — Amestoy Estates, Royal Oaks, Encino Park — lots are large and largely flat and the binding limit is floor area under the Mansionization Ordinance. South, in the Encino Hills, the Hillside Ordinance ties buildable area to slope and adds grading caps, height measured from natural grade, haul route exposure and fire-zone construction. Same neighborhood name, different project.
Can I keep horses on an Encino property?
Some Encino lots, particularly in and around Amestoy Estates, carry legacy horsekeeping rights, but it is parcel-specific and depends on zoning and lot size rather than on the neighborhood generally. If equestrian use matters to you, confirm it for the specific address before purchase — and if it is permitted, we design the equestrian scope alongside the residence rather than appending it later.
Should I remodel the ranch house or replace it?
Encino has a deep stock of 1950s to 1970s ranch homes sitting on lots that are worth far more than the structure, so the question comes up constantly. It turns on how much of the existing floor area and structure you can keep usefully, what your allowance would be on a new build, and how the two compare on cost and schedule. We model both options at the feasibility stage — a remodel-and-addition scheme against a replacement scheme — so the decision is made against real images and real numbers rather than a hunch.
Do I need a permit to remove a tree on my lot?
If it is a protected species above the specified size — native oak, Western sycamore, California bay or toyon — then yes, and the protected zone extends well past the trunk, so grading and paving nearby can trigger it too. Removal requires a permit, an arborist's report and replacement planting. On the larger Encino lots these trees are usually an asset worth designing around.
