ADU Construction in Pacific Palisades
Serving 90272 and Santa Monica, Brentwood, Malibu
An ADU in Pacific Palisades is rarely a flat backyard drop. Most 90272 lots are graded, sloped, or terraced, sitting behind Cape Cod two-stories, Mediterranean estates, or mid-century hillside houses — and half of them sit inside a Coastal Commission jurisdiction depending on where they are relative to PCH. Design Onn Point runs the parcel check and the slope study before we draw anything.
Real projects. Real prices.
73 finished remodels published with their final price — nothing hidden.
What our finished LA work actually cost: 27 kitchens ran $23k–$84k, median $50k; 28 bathrooms $28k–$105k, median $38k; 17 whole-home remodels $36k–$440k, median $150k. Real final prices from our own job records, not estimates.
$30,000 An emerald herringbone shower behind glass, with brass fittings and a walnut double vanity.
$34,800 White uppers over warm grey shaker lowers, white quartz, and a stainless chimney hood.
$45,000 Rust and blue slate-tone tile over a pebble mosaic shower floor, with bronze fittings.
$84,000 Warm grey shaker cabinetry with quartz counters, plus floating vanities in dark stone tile.
$242,700 Structural work to open up the space, a vaulted ceiling, solid wood floors, kitchen and two baths.
$250,000 White shaker cabinetry and veined quartz, with hex-mosaic walk-in showers.
ADU building in the 90272 hills
Slope and grading come first
Before floor plan, we need the topography. On a graded Palisades lot, the foundation for a detached ADU can cost more than the framing above it. We work the grading number early so nobody is surprised at contract time.
Coastal Commission for west-of-PCH parcels
If your parcel is west of PCH, Coastal Commission review can apply on top of the standard ADU permit. That adds review time and design constraints on height, mass, and view impact. We tell you at the first visit whether your parcel is in that zone.
LADBS ADU submittal
Pacific Palisades ADUs go through LADBS. The standard state ADU ordinance path applies unless the coastal overlay pulls a second review into the picture. Design Onn Point handles the submittal and the plan-check corrections.
Access and staging on hillside lots
A hillside Palisades lot with a narrow driveway can double staging time. Concrete pumps, crane picks for framing packages, and material lifts get planned before we mobilize.
Where the +15-25% premium comes from
Palisades ADUs sit 15-25% (+15-25%) above our baseline. Foundation on slope, coastal review time, and access difficulty are the three lines that account for most of the gap. We show you exactly how those numbers stack on your project.
Fire zone first, then the unit
Much of 90272 sits in a designated high fire hazard area, and that classification governs an ADU more than any design preference will. It reaches the materials on the outside of the building, the roof assembly, the venting, the glazing and the planting allowed around it, and it is not a set of options. Owners often arrive with a picture of a light timber garden studio and have to be walked through why the built version looks different. It can still be a beautiful building. It cannot be that particular building. We put the fire-zone requirements in front of the design conversation rather than after it, because a design developed without them gets redrawn.

What's different about adu construction in Pacific Palisades
Palisades ADUs face stricter wildfire defensible-space rules
Post-January 2025 fire, Palisades parcels in the very-high fire-severity zone are subject to wildfire-zone build-out specs: Class A roofing, ember-resistant exterior wall assemblies, screened vents, and defensible-space clearance around the structure. State ADU law generally permits placement on most parcels, but the build-out specifications are tighter than ADU rules elsewhere in LA. We integrate the fire-zone requirements into the ADU design from the start, not as post-design adjustments.
Hillside ordinance applies to most Palisades parcels
LADBS Hillside Ordinance review applies to Palisades parcels with slope, which adds structural and grading considerations to the standard ADU plan check. The combination of hillside and fire-zone review can extend the permit timeline relative to a flat-lot, non-fire-zone ADU. We design ADU footprints to minimize cut/fill where the parcel allows, which keeps the soils and grading scope narrower.
Insurance considerations affect Palisades ADU economics
Post-fire, Palisades fire-insurance availability and cost differ from pre-fire reality. Adding an ADU can affect coverage or premiums. We don't advise on insurance directly — that's a conversation between the client and their broker — but we flag insurance review as a project-feasibility input early in design so coverage decisions happen before the ADU is committed, not after the build is under way.
