What Self-Performed Trades Mean for a Custom Home

Most custom homes in Los Angeles are built by a general contractor who hires subcontractors for each trade: one company for the foundation, another for framing, others for the envelope, the systems and the finishes. A self-performing builder keeps a large share of that work on its own payroll. The crews who pour the foundation and the crews who install the finishes answer to the same people.

Why it changes the schedule

When every trade is a separate company, the schedule is a chain of other people’s calendars. A framing crew that finishes another job late pushes everything behind it. With in-house crews, the builder sets the sequence and moves its own people between phases, so a delay in one area is easier to absorb.

Why it changes quality control

Quality is easier to hold when the person checking the work also directs the crew that did it. Problems are found earlier, while the wall is still open, instead of at a final walk-through. On a custom home, where many details are drawn once and built once, that early feedback matters.

Why it changes cost

Self-performed work removes a layer of subcontractor markup on the trades the builder runs itself. It also gives the builder real cost data from its own jobs, which makes early budgets and value-engineering reviews more reliable.

What it means for architects and designers

For an architect or an interior designer, a self-performing builder means fewer hand-offs between the drawings and the field. Questions about a detail go to the people who will build it, and the answer comes back from the same team that carries it out.

Questions to ask any builder

• Which trades do you perform with your own crews, and which do you subcontract?
• Who runs the work on site day to day, and who signs off each phase?
• How do you report schedule and budget during the build?

The answers tell you how much of the project the builder actually controls.
