On a hillside lot in Los Angeles, you are never just building a wall, you are managing soil, water, and seismic pressure at the same time. Lots across the Hollywood Hills, Laurel Canyon, Bel Air, and Pacific Palisades sit on grades that shift after heavy rain and move during earthquakes, which means a retaining wall built without proper engineering is a liability waiting for the next wet winter.
With more than 4,300 projects completed, we showcase a selection of our retaining wall work, built with the expertise to perform on both standard properties and complex hillside conditions.
Each wall is built with care, precision, and durability in mind, serving homeowners across Hollywood Hills, Laurel Canyon, Bel Air, Silver Lake, Pacific Palisades, and surrounding hillside areas.

DiBara Masonry has been solving hillside soil problems in Los Angeles for four generations and more than 100 years. We design every wall around the actual grade, soil, and drainage path of your property, never a one-size template, and back it with a licensed CSLB contractor (#1002003) and, where required, a stamped structural engineer.

A flat-lot wall mostly holds back loose fill from a single grade change. A hillside wall resists the ongoing downhill push of an entire slope, plus whatever load sits above it, a driveway, a pool, or a second structure. That surcharge changes the footing size, the steel reinforcement, and often the whole wall type.
Hillside lots also concentrate water. Rain that would spread out on a flat yard instead funnels toward the base of the slope, building up hydrostatic pressure behind the wall. That is why drainage design, not just wall thickness, decides whether a hillside wall lasts decades or fails within a few rainy seasons. Our how to choose the right retaining wall guide breaks down how those factors change the design.
Soil creep or rutting after rain, a fence that has started leaning above a slope, and cracks appearing near the top of a grade are all early warning signs. So are patios or parking areas that feel like they are losing support, or water pooling behind an existing wall instead of draining away. We cover the full list in 7 signs you need a retaining wall.
You do not need a dramatic hillside to have hillside conditions. If your yard is not flat, you already have soil movement, water flow, and uneven load working against you, acting early, before a crack becomes a slide, is almost always the cheaper and safer path. When a wall is already moving, our guide on whether to repair or rebuild a failing sloped wall explains how we make that call.
Gravity walls use heavy concrete or CMU mass to resist sliding and overturning, and work well on shorter walls or tiered terraces that step a steep lot into usable flat areas. Cantilevered walls add a reinforced footing and stem with the heel extending into the backfill, which makes them efficient for medium heights carrying a driveway or patio surcharge above.
For taller walls or lots with very limited excavation room, we use anchored systems, tiebacks or soil nails, to add resistance without a massive footprint. The right choice depends on height, soil, access, and the load above the wall, which is exactly what we assess during the free site visit before quoting a fixed price. See our concrete retaining walls page for engineered poured-in-place options.
Most engineered hillside walls in Los Angeles require a permit, and height, surcharge, or proximity to a property line typically triggers the requirement for a licensed structural engineer. We coordinate directly with LADBS permit requirements for retaining walls on plan check and schedule the standard inspection stages, footing, rebar, grout, and final, as part of the project timeline. Our summary of the 2026 LA retaining wall requirements covers what applies to most residential lots.
Southern California walls also carry real seismic loads on top of everyday soil pressure. Our engineered designs size footing width, embedment depth, and reinforcement to current California Building Code seismic requirements and ASCE 7 seismic design loads, informed by USGS earthquake hazard maps for the LA basin. That is one more reason a taller hillside wall is not a project to build without an engineer’s stamp.
Trapped water is the number one cause of retaining wall failure, and it is entirely preventable. Every hillside wall we build includes washed gravel backfill with filter fabric, a perforated drain pipe at the footing elevation with a positive outlet, and weep holes where the design calls for them. Our retaining wall drainage guide walks through each layer.
We also apply a waterproofing membrane on the soil side of concrete or CMU walls and grade the surface above the wall so stormwater moves away from the structure instead of building up behind it. This is the difference between a wall that needs attention every rainy season and one that simply disappears into the landscape. Where a wall ties into the house, we pair it with foundation waterproofing services.
Poured concrete gives the most flexibility for engineered cantilevered and anchored walls, while reinforced CMU (cinder block) offers a faster, cost-effective build for gravity and shorter cantilevered designs. Both accept a natural stone or brick veneer where the client wants the finished look of full masonry without the added structural cost.
We also frequently replace aging railroad-tie or timber hillside walls, which rot, attract termites, and can fail without warning as the wood weakens. Those get rebuilt in code-compliant concrete or CMU with proper drainage designed in from day one, not retrofitted after the fact. For budgeting, see our retaining wall cost breakdown.
It starts with a free quote based on basic project details, followed by an in-person site visit where we measure the slope, check soil conditions, and review access before confirming a fixed price, no hidden costs after the fact. An initial proposal follows within 72 hours of that visit.
Once you sign, our team confirms a start date, pulls permits, coordinates any required engineering, and assigns both a project manager and an on-site foreman to your build. You get a clear schedule up front and consistent updates through every LADBS inspection stage until final sign-off.

Most hillside retaining walls in Los Angeles run between $75 and $200+ per linear foot, depending on wall height, soil conditions, access, and material. A short gravity wall on an easy-access lot sits at the low end; a tall engineered cantilevered or anchored wall on a steep, tight-access hillside sits at the high end. We provide a fixed price only after a site visit, since drainage, excavation, and engineering requirements vary lot by lot.
In most cases, yes. LADBS generally requires a permit for walls above a certain height, walls that carry a surcharge such as a driveway or pool, and any wall near a property line or structure. We pull permits, coordinate the required engineering, and schedule inspections as part of every hillside project so the wall is fully code-compliant.
There is no single best type; the right system depends on height, soil, and space. Gravity walls work well for shorter, tiered slopes; cantilevered concrete or CMU walls handle medium heights with surcharges like driveways; anchored systems with tiebacks or soil nails are used for taller walls or lots with limited excavation room. We recommend the system after reviewing the actual soil and grade on-site.
Water is the leading cause of retaining wall failure, so every hillside wall we build includes a drainage plan: washed gravel backfill, a perforated drain pipe at the footing with a positive outlet, weep holes where specified, and a waterproofing membrane on the soil side of the wall. Surface grading is also adjusted to move stormwater away from the wall instead of behind it.
A typical hillside wall takes anywhere from two to six weeks once permits are approved, depending on height, length, and site access. Taller engineered walls with anchors or extensive excavation take longer. We give a specific schedule after the site visit and factor in the standard LADBS inspection stages: footing, rebar, grout, and final.
Yes, and it is one of our most common hillside calls. Timber and railroad-tie walls rot, attract termites, and can fail without warning once the wood weakens. We remove the failing structure and replace it with an engineered concrete, CMU, or stone-veneer wall built to current code, with proper drainage designed in from the start.
Southern California walls must resist both constant soil pressure and seismic loading. Our engineered designs size the footing width, embedment depth, and steel reinforcement to account for regional seismic forces per current California Building Code requirements, which is one reason taller hillside walls almost always require a licensed structural engineer.
A gravity wall relies on its own mass, usually heavy concrete or CMU, to resist the soil behind it, which makes it a good fit for lower walls or tiered terraces. A cantilevered wall uses a reinforced footing and stem, with the heel extending back into the backfill, which lets it resist greater height and surcharge loads with less material.
Yes. Most hillside walls in Los Angeles that exceed a certain height, carry a surcharge, or sit near a property line require a stamped engineering design. We coordinate directly with licensed structural engineers on footing size, reinforcement, and anchor design, then build to those approved plans and through the required LADBS inspections.
