What We Build on Slopes
New hillside homes, additions and decks tied into existing hillside structures, plus the foundation and retaining work that holds them up.
- Caissons, grade beams and deepened footings
- Engineered retaining walls and shoring
- Hillside additions and cantilevered decks
- New view-lot custom homes
- Driveway, access and drainage work
Hillside Construction Conditions in Beverly Hills
The housing stock spans 1920s Spanish and traditional homes to 1960s moderns, and the older ones need the usual invisible work: rewiring, replumbing, foundation bolting and insulation. Design review applies to exterior changes in parts of the city, and street trees, setbacks and hedge rules can affect a plan. Flats build easily; the hillside north of Sunset needs grading and geotechnical work.
- City of Beverly Hills plan check with its own local amendments
- Enforced construction hours and neighbor notification requirements
- 1920s Spanish and traditional homes needing rewire, replumb and bolting
- Exterior design review in parts of the city
- Hillside grading and geotechnical scope north of Sunset
Soils and the Hillside Ordinance
Hillside parcels in LA fall under grading limits, height restrictions measured off natural grade, and haul-route rules for exported dirt. A geotechnical report drives the foundation design, and it's the first thing we order.
- Geotechnical and soils investigation
- Grading and export quantity limits
- Haul-route approvals where required
- Height and setback verification off natural grade
- Drainage and erosion control
Access Is Half the Cost
On a narrow canyon street, how material and equipment reach the site can matter as much as the design. We plan staging, craning and delivery sequencing early instead of discovering it mid-project.
- Site access and staging plan
- Crane and pump placement
- Neighbor notification and street use permits
- Sequenced deliveries to keep the street open
FREQUENTLY ASKED QUESTIONS
Do you do hillside construction in Beverly Hills?
Yes. Beverly Hills is part of our regular service area. We'll come out for a free on-site consultation, walk the property, and tell you what's realistic before you spend anything on design.
What does hillside construction cost in Beverly Hills?
Scoped after soils and structural engineering. Site conditions in Beverly Hills and your material selections move the number, which is why we price after walking the property rather than over the phone.
Who issues the permit in Beverly Hills?
Permits for this work go through Beverly Hills Community Development. We handle the submittal, plan check corrections and inspections as part of the project.
How much more does hillside construction cost?
Deep foundations, retaining walls, grading and difficult access typically add a meaningful premium over a comparable flat-lot project. The soils report and engineering tell us how much, which is why we scope it after those come back.
Do I need a soils report?
For hillside work in Los Angeles, almost always. The geotechnical report specifies whether you need caissons, grade beams or deepened footings, and plan check will ask for it.
Can you add on to a house on a steep slope?
Yes. Hillside additions are common in Silver Lake, the Hollywood Hills, Sherman Oaks and Glendale. They need structural engineering to tie the new work into the existing structure and the slope below it.
Do you take hillside projects near me across the LA area?
Yes. We build on slopes throughout Los Angeles County and nearby counties within roughly 100 miles of Woodland Hills, from the Hollywood Hills and Silver Lake to Sherman Oaks, Glendale, Malibu and the Conejo Valley.
