A licensed design-build contractor for Los Angeles & Orange County
YBL Design & Build is a licensed design-build general contractor (CSLB #1152391) serving homeowners across Los Angeles and Orange County. Design-build means one accountable team handles your entire project — 3D design, permits, and construction — under one contract and one clear price, so there is no finger-pointing between a separate architect, permit service, and crew.
We specialize in ADUs and garage conversions, room additions, kitchen and bathroom remodeling, and complete home remodels — from the first free 3D design through the final walkthrough.

Our design-build process, start to finish
One team from the first sketch to the final walkthrough — so nothing gets lost in a hand-off.
Free 3D & layout design
We start with a free consultation, then design your project in 3D with real layouts — part of our estimate, before you commit to anything.
One fixed price
Once the design is set, you get a single written price for the agreed scope — not a moving estimate that creeps during the build.
Permits & approvals
We prepare the plans and handle permitting with the right authority for your address, whether that is LADBS, your city, or the county.
Construction
Our crews build it with one point of contact and regular updates, so you always know what is happening and what comes next.
Final walkthrough
We walk the finished project with you, confirm every detail, and hand over a home that is permitted, inspected, and done right.
Typical project timelines
Ranges from start to finish. Actual time varies with scope, finishes, and city permitting.
| Project type | Typical timeline |
|---|---|
| Bathroom remodel | ~3 weeks |
| Kitchen remodel | ~5 weeks |
| Room addition | ~2.5 months |
| Garage conversion (ADU) | 3–5 months |
| Detached / new-build ADU | 5–9 months |
| Whole-home remodel | Varies by scope |
These are typical YBL ranges and depend on your project’s size, structural work, and how quickly your city issues permits. You get a realistic schedule with your fixed price.

What does “design-build” actually mean?
It means one company handles both the design and the construction of your project under a single contract. Instead of hiring a separate architect, permit expediter, and general contractor, you work with one accountable team from the first 3D design through the final walkthrough — which keeps the design, the budget, and the schedule aligned.
Is the design really free?
Yes. Your free consultation, 3D design, and layout are part of our estimate — you see your project and your fixed price before you commit to construction.
Do you handle permits?
Yes. We prepare the plans and manage permitting with whichever authority covers your address — LADBS for the City of Los Angeles, your city’s building department, LA County, or an Orange County city. Requirements differ by jurisdiction, and we confirm yours before design.
How much do projects cost?
It depends on the type of project, your home’s condition, and your finishes. Rather than a moving estimate, we give you one fixed price after the design is set. You can read honest cost ranges in our guides to garage conversions in Los Angeles and ADU costs in Orange County.
How long will my project take?
Typical ranges run from about three weeks for a bathroom to several months for an ADU or whole-home remodel — see the timelines table above. You get a realistic schedule along with your fixed price.
Which areas do you serve?
We serve homeowners across Los Angeles and Orange County, from the San Fernando Valley and the Westside to the South Bay, and throughout Orange County including the coastal cities.
Are you licensed and insured?
Yes. YBL Design & Build is a licensed California design-build general contractor, CSLB #1152391, and any project that requires a permit is built by a licensed team.
