Your Hillside Lot Doesn't Need a Builder. It Needs a GC Who Reads Soils Reports.
Caisson-and-grade-beam foundations, BHO §B/§C compliance, geotech-engineer-of-record coordination, slope-creep mitigation. From Hollywood Hills cantilevers to Calabasas estate pads — we build the 30% of LA that everyone else turns down.
LA-Specific Compliance, Cost & Permitting Realities
- Most LA contractors flat-out refuse hillside work — they don't have the geotech relationships, the caisson rig contacts, or the LADBS hillside-grading desk knowhow. The 'we'll do anything' generalist who quoted you cheap on a flat-lot price is the same one who'll abandon the project at first sign of soils trouble.
- Hillside lots have 4 hidden cost layers flat-lot builders never quote: (1) soils report + geotechnical engineer of record $8-22K, (2) caisson foundation $25-85K depending on depth-to-bedrock, (3) grade-beam tying caissons $15-45K, (4) retaining walls $200-650/lf. You will pay these. The question is whether you find out in pre-construction or mid-pour.
- LAMC 12.21.A.17 hillside ordinance + BHO Baseline Hillside Ordinance §B (smaller lots) and §C (larger) cap your buildable envelope, FAR, height, and driveway grade (20% max). If your architect didn't run a BHO analysis BEFORE schematic design, your plans will not pass plan check. We catch this in the feasibility walk — for free.
- View-corridor preservation, Mulholland Scenic Parkway design review, ridgeline-protection setbacks — these add 4-12 weeks to permitting if your team doesn't pre-meet with LADBS hillside section. We pre-meet on every project.
2026 LA Cost Bands
| framing | Real 2026 LA hillside pricing. Anyone quoting outside these ranges either doesn't know what they're walking into, or is planning to change-order you into them later. |
|---|---|
| ranges | [{'scope': 'Hillside addition (existing house, new wing on slope)', 'price_band': '30-60% premium over equivalent flat-lot per-sqft'}, {'scope': 'New hillside construction (full home)', 'price_band': '$450 – $1,100 per sqft + foundation premiums'}, {'scope': 'Caisson foundation only (typical 4-12 piers)', 'price_band': '$25,000 – $85,000'}, {'scope': 'Grade-beam foundation tying caissons', 'price_band': '$15,000 – $45,000'}, {'scope': 'Retaining wall (engineered, with drainage)', 'price_band': '$200 – $650 per linear foot'}, {'scope': 'Hillside driveway (20% max grade, engineered)', 'price_band': '$35,000 – $95,000'}] |
Risk Reversal — Guarantees
- Fixed feasibility-walk price — $0. We walk your lot, pull the BHO classification, give you a real ballpark before you spend a dollar on architect fees that may be wasted.
- Soils + geotech pass-through at 0% markup — the geotechnical engineer of record bills you direct. We coordinate. You see the invoice.
- Single GC-of-record — one CSLB license on the permit, one PM, one number to call. Not a brokered project handed to 4 different subs who blame each other when slope-creep shows up at month 9.
- Pre-construction agreement is non-binding past feasibility — if BHO analysis kills your build, you walk away owing nothing.
Objections Handled Up Front
- {"objection": "Three other GCs already quoted me \u2014 yours is the highest.", "response": "Pull the three quotes. I'll show you line-by-line where they didn't include caisson engineering, grade-beam, or geotech coordination. They're not higher than us \u2014 they're missing the work that costs you $80K in change orders at month 7."}
- {"objection": "Why do I need a geotechnical engineer if my lot looks stable?", "response": "LADBS hillside section will not stamp your permit without a soils report. Period. Stable-looking lots in Hollywood Hills sit on 60 feet of decomposed granite over bedrock \u2014 caisson depth varies 8 to 35 feet on the same parcel. The geotech tells us where bedrock actually is. Skipping this is how you end up with $200K in unplanned drilling at month 4."}
- {"objection": "Can't I just use a standard foundation if I cut into the slope?", "response": "Sometimes \u2014 if your BHO classification, soils class, and drainage plan all support it. Often not. We tell you which one you are during feasibility. Most hillside lots that 'look like they could' need at minimum a grade-beam + partial caisson hybrid."}
