Where It Starts
Building a Custom Home on an Existing Lot Starts Long Before the Foundation
A custom home builder in Los Angeles manages the full sequence — from soils testing through final occupancy certification — on a single residential lot you already own.
This is new home construction on an infill lot — a vacant or underbuilt parcel of land located inside an already-developed urban area. Infill lots in Los Angeles come with specific access conditions, grading constraints, and zoning histories that affect every phase of the build. US LA Home Remodeling Inc holds CSLB License #1071589, a Class B General Building Contractor license that authorizes the full construction scope — structural, mechanical, and finish — under one contractor. You don’t manage separate contracts for each phase. We do.
The result is a permitted, inspected, occupied home — built to your program on your lot.
Infill Lots in LA
Los Angeles Infill Lots Require More Upfront Engineering Than Most Owners Expect
In Los Angeles, the pre-construction phase often takes longer than the build itself.
That’s not an exaggeration. It’s how LA DBS — the Los Angeles Department of Building and Safety — works.
Here’s what most landowners don’t realize about new construction in LA: the permit application cannot be submitted until the soils report is complete. That report has to be in hand before the structural engineer finalizes the foundation design. The foundation design has to be finalized before the architectural drawings can be calibrated to the actual site conditions. And the grading plan — which shows how the existing land elevation will be changed to support construction — has to be coordinated with both.
We dispatch from Tarzana, centrally positioned in the San Fernando Valley. That puts us close to hillside lots in the Santa Monica Mountains foothills and flat-lot subdivisions throughout the Valley floor. Both lot types come up in our new home construction Los Angeles work. Hillside lots require expanded geotechnical review before any plan check can proceed. Flat Valley lots move faster — but they still require the same correct sequence.
Skip the sequence and LA DBS returns the application. That restart costs months.
What Sequencing Taught Me
The Lot I Still Think About — and What It Taught Me About Sequencing
I took a call from an east Valley landowner who had already paid for architectural drawings.
They were detailed, well-drawn plans. The problem was that the lot had never had a soils report done. Nobody had tested what was actually in the ground.
I’m Uzi Ezra, Founder and CEO of US LA Home Remodeling Inc. I started this company in Los Angeles in 2020, and this project stands out because it showed me exactly what happens when the pre-construction sequence is reversed.
When we finally got the soils report back, the geotechnical engineer flagged expansive clay soils in the upper three feet. That finding changed the foundation design from a standard slab-on-grade to a post-tension slab with deeper perimeter footings. The architectural drawings — the ones the owner had already paid for — had to be revised to reflect the new foundation geometry. The structural engineer revised their calculations. Then the drawings went back to the architect for coordination. That sequence added ten weeks and a real dollar cost before a single permit application was filed.
Here’s what I tell every landowner now: the soils report is not a box to check after you’ve designed the house. It’s the first document. It tells the structural engineer what the ground will and won’t support. That answer shapes the foundation. The foundation shapes the floor plan. The floor plan shapes everything else.
We start every custom home construction Los Angeles project with the soils report. Then the grading plan. Then the architectural drawings — calibrated to what the site actually allows. Title 24 compliance documentation, which covers California’s mandatory energy code for new homes including insulation, window performance, HVAC efficiency, and solar-readiness requirements, is prepared in parallel with the drawings so it’s ready for plan check submission.
That order isn’t a preference. In Los Angeles, it’s the only sequence that produces a clean plan check submittal on the first attempt.

Soils Findings
What Happens If the Soils Report Comes Back With a Problem?
If the geotechnical report identifies a soil condition that affects the foundation, we address it before design proceeds — not after drawings are complete.
This question comes up in nearly every new construction consultation. The short answer: a difficult soils finding is not a project-ender. It’s information. Expansive clay, high groundwater, or fill material in the upper soil layers each have established engineering responses. Post-tension slabs, deepened footings, soil replacement, or compaction specifications — the structural engineer specifies the right response once the soils data is in hand.
What we don’t do is design around an assumption and hope the soils come back clean. That approach creates the revision cycle described above. We get the report first, read the findings with the structural engineer, and then design to those conditions. The permit drawings reflect the actual site. Plan check reviewers see drawings that match the soils data. The application moves forward.
We hold CSLB License #1071589. That license authorizes the full project scope — from soils coordination through final occupancy certification — under one licensed entity.

Our Standards
Our Standards on Custom Home Construction in Los Angeles
Every custom home we build in Los Angeles is designed to pass plan check on the first submittal and every inspection on the first call.
That standard drives how we prepare documents, specify materials, and schedule trades.
1
Soils Report First
No foundation design begins without a completed geotechnical report for that specific lot.
2
Grading Plan Coordinated Before Drawings Are Finalized
Earthwork scope affects setbacks, drainage, and access — all of which appear on the permit drawings.
3
Title 24 Energy Compliance Prepared in Parallel
Documentation is produced alongside architectural drawings, not as an afterthought before submission.
4
Structural Drawings Peer-Reviewed
Checked against the soils engineer’s recommendations before plan check submission.
5
LA DBS Plan Check Submission Managed Directly
Handled by US LA Home Remodeling Inc as the contractor of record — no coordination burden on the property owner.
6
Occupancy Certificate as the Finish Line
The document LA DBS issues after final inspection confirms the home meets all code requirements — that’s the project’s finish line, not the framing stage.
Three coats of waterproofing on a foundation wall where the soils report flagged moisture. Not two. That’s the standard.
Phase by Phase
How We Build a Custom Home in Los Angeles: Phase by Phase
The build a custom home Los Angeles process follows a fixed sequence — and each phase has a specific LA requirement attached to it.
Diagnostics: Pre-Construction Engineering
Before any design work begins, we order the soils report and review the lot’s current grading conditions, easements, and utility connection points. The geotechnical engineer tests the soil bearing capacity, identifies any reactive soil conditions, and specifies the foundation type and depth. On hillside lots in Los Angeles, this phase also includes a geotechnical sign-off that LA DBS requires before plan check can proceed. The grading plan is developed from this data — it shows how the land will be cut, filled, and shaped to support the building footprint, drainage, and driveway access.
This phase typically runs four to eight weeks depending on the site’s complexity and the geotechnical firm’s current schedule.
Implementation: Design Coordination and Construction
With the soils and grading data confirmed, the architectural and structural drawings are produced to the actual site conditions. Title 24 energy compliance documentation is prepared for submission alongside the structural drawings. We submit the complete package to LA DBS as the residential new construction contractor of record.
Once the permit is issued, construction proceeds in the inspected sequence: foundation and underground utilities, framing and sheathing, rough mechanical and electrical, insulation, drywall, and finish. Each phase is inspected by LA DBS before the next phase is enclosed.
Post-Service Testing: Inspections and Occupancy Certification
Final inspection is not a single visit — it’s the confirmation that every prior inspection is signed off and the completed home meets all code requirements. After final inspection approval, LA DBS issues the occupancy certificate. That document legally authorizes occupancy of the home. No occupancy certificate means the home cannot be legally occupied, regardless of how finished the construction is.
We schedule and manage every inspection phase directly with LA DBS.

FAQ
Common Questions About Building a Custom Home in Los Angeles
Why does the soils report have to come first?
The permit application cannot be submitted until the soils report is complete. That report has to be in hand before the structural engineer finalizes the foundation design, and the foundation design has to be finalized before architectural drawings can be calibrated to actual site conditions. The soils report tells the structural engineer what the ground will and won’t support — that answer shapes the foundation, the foundation shapes the floor plan, and the floor plan shapes everything else.
What happens if the soils report identifies a problem?
A difficult soils finding is not a project-ender — it’s information. Expansive clay, high groundwater, or fill material in the upper soil layers each have established engineering responses: post-tension slabs, deepened footings, soil replacement, or compaction specifications. The structural engineer specifies the right response once the soils data is in hand, and we design to those conditions before drawings are produced.
How long does the pre-construction phase take in Los Angeles?
The diagnostics phase typically runs four to eight weeks depending on the site’s complexity and the geotechnical firm’s current schedule. In Los Angeles the pre-construction phase often takes longer than the build itself — and skipping the sequence means LA DBS returns the application, a restart that costs months.
Do hillside lots require anything extra?
Yes. Hillside lots require expanded geotechnical review before any plan check can proceed, including a geotechnical sign-off that LA DBS requires. Flat Valley lots move faster, but they still require the same correct sequence: soils report, then grading plan, then architectural drawings calibrated to what the site allows.
What is an occupancy certificate and why does it matter?
It’s the document LA DBS issues after final inspection confirms the home meets all code requirements. It legally authorizes occupancy of the home. No occupancy certificate means the home cannot be legally occupied, regardless of how finished the construction is — which is why we treat it as the project’s finish line, not the framing stage.
Who manages the LA DBS plan check submission?
US LA Home Remodeling Inc, as the contractor of record — there’s no coordination burden on the property owner. CSLB License #1071589 is a Class B General Building Contractor license authorizing the full construction scope, from soils coordination through final occupancy certification, under one licensed entity.
