Learn More →OUR PROCESS
One Team, Start to Finish
We don’t hand you off to a separate architect, a different permit service, or an unrelated crew. Your project stays with our team from the first drawing to the final walkthrough.
Free 3D Design
We start every project with a free initial 3D design so you can see exactly what you’re getting before committing to anything. No guesswork. No surprises at the end.
Plans & Permits
We prepare all architectural drawings and manage the full city permitting process. You don’t need to navigate city halls or chase building inspectors — we handle it.
Construction
Our licensed crew builds to the approved plan. You receive a weekly project calendar so you always know what’s happening on your property and when.
Final Walkthrough
We walk through every detail together before we close the project. Your sign-off is the last thing that happens — not ours.
WHY YBL
Built Around Your Peace of Mind
Planning a major construction project in Los Angeles comes with a lot of unknowns — design decisions, city permits, construction schedules, and a final bill that may look nothing like the original quote.
YBL was built to fix that. Every project starts with a clear plan, an agreed price, and a schedule you can follow. We handle the hard parts so you don’t have to.
Get a Free Estimate →Free Initial 3D Design
Before you commit to a dollar of construction, you’ll see exactly what your finished project will look like. Every YBL project starts with a complimentary 3D design — so your decisions are confident ones, not guesses.
No Surprise Change Orders
Our projects are planned in full detail before construction begins — structural, electrical, finishes, and fixtures. The price you approve at the start is the price you pay at the end.
Design, Permits & Construction Under One Team
One phone number, one timeline, one team responsible for everything. No hiring a separate architect. No managing the permit process yourself. No coordination problems between contractors.

What Our Clients Say
★★★★★ 5-Star Rated on Google
“We hired Isaac and his team for a room addition and full home remodel, and the experience exceeded expectations from day one. The free initial 3D design made it incredibly easy to visualize the project before starting — and everything was built exactly as planned.”
Lauren
Room Addition & Full Home Remodel · Los Angeles
“From the first meeting to the final walkthrough, YBL was organized and completely transparent. The weekly project updates kept us informed every step of the way. Our ADU came out exactly as the 3D design showed — no surprises, no extra charges.”
Michael R.
ADU Garage Conversion · West Los Angeles
“YBL handled everything — the design, the permits, the city approvals, and the construction. We didn’t have to deal with a single city official ourselves. Our room addition came in on time and on budget, and the finish quality exceeded what we expected.”

COMMON QUESTIONS
Common Questions
Planning a major project means a lot of questions. Here are the ones we hear most often.
-
A design-build contractor manages the full project under one team — design, permitting, and construction. You don’t hire a separate architect, a separate permit expediter, and a separate crew. YBL handles all phases, so there’s one point of contact and one team responsible for the outcome.
-
Yes. We prepare all architectural and structural drawings, submit them to the city, and manage the inspection process throughout construction. Most homeowners find the permit process overwhelming — we take that entirely off your plate.
-
ADU costs in Los Angeles typically range from $150,000 to $350,000 or more, depending on size, scope, and finishes. Garage conversions are generally less expensive than new build ADUs. We provide a detailed, no-obligation estimate after reviewing your property and goals.
-
We schedule a free consultation to understand your property, goals, and budget. From there, we produce a free initial 3D design so you can see what your project will look like before anything is built. Once you approve the design, we move into architectural drawings, permitting, and construction scheduling.
-
Yes — most of our clients come to us with an idea, not a plan. We start from scratch: listening to what you want, designing a solution that fits your lot and budget, and then handling permitting and construction. You don’t need to come prepared with drawings or specifications.
-
Timelines depend on project scope and city permitting times. A garage conversion typically takes 3–5 months from permit approval to completion. A new build ADU or room addition generally takes 5–9 months. We provide a project calendar at the start of every job so you always know where things stand.
-
Yes. YBL Design & Build is a California-licensed general contractor (License #1152391), fully bonded and insured for residential construction throughout Los Angeles County.
