Berg Development builds backyard residences, roofs and solar in Los Angeles. Design-build, led by a licensed general contractor with a degree in architecture: the people who draw it are the people who build it, so the drawings are buildable and the price holds.

Three short films, in Taron's own words. The reasons have not changed since the first project.
Why we started“We started Berg because the people we built for are not investors with a fund. They are families with a mortgage. A backyard residence in Los Angeles rents for about $2,000 to $3,500 a month. That can cover most of a mortgage payment, or it can be the retirement income a house finally pays back.”
The introduction · rent figures are estimates
One team“For seven years my team and I have been building in Los Angeles. Backyard residences, roofs and solar. Behind every project is one licensed team: design, engineering, permits and construction under one roof, led by a licensed general contractor with a degree in architecture.”
The introduction
Solar“Most of what you pay is not panels. It is commissions. We built this platform to cut the middleman out: one set price, the same for everyone, and the same licensed team that designs it installs it. No pitch in your living room, no commission in your bill.”
The solar film
Roofing“Someone paid ten, even twenty times more than the job was worth. It is crazy that this still happens to people. So we changed how a roof is bought: choose the roof, the material and the work, sign online, pick your week.”
The roofing film
Every day“You never wonder what happened today. In your project app you see the progress every night: what the crew did, the photos they took, their comments. And you can send your own photos and questions right back.”
The introduction
Filmed on Berg sites in Los Angeles. Nothing in the films is a quote or a contract; your price comes from the studio and the shop.

Taron Sargsyan founded Berg Development after seven years of building in Los Angeles. He is the licensed general contractor who leads every job and holds a degree in architecture, so the lot read, the design, the permits and the site are one responsibility: his. Roofing and solar are installed by Berg's own crew, the same people in these photos. Call (747) 588-6496 and you reach him.



Each one is priced online from public county records, by the same people who build it. Residences and roofing serve Los Angeles County; solar serves all of California.
Type your address and the studio reads the county parcel, your house and the zoning, places the residence on your lot and gives you an honest all-in range. One hundred named residences by size, three looks, then your style, color, roof and finishes. The next step is a $500 Design Session, refundable until the session and credited to your project.
Shingle, tile or flat; the brand, the color and the work: fascia, gutters, tear-off, plywood. We size it from the county building outline. Your online price, confirmed at the site visit before work starts. Sign online, pick your week, and Berg's own crew installs it with a 10-year workmanship warranty.
No door knocker, no sales rep, no commission in your bill. We read your roof from the county data; you choose how much of your usage to cover, the panel, the inverter and the battery, and you see your price. Sign online, pick your week, and Berg's own crew installs it, across California.
The studio reads the parcel, your house and the zoning before anyone draws. If a detached residence does not fit, it says so and shows the garage conversion or the attached option that does.
An all-in range with checkpoints: construction, plans, permits, utilities and site work listed line by line. Every change is priced before it happens, never after.
Design, engineering, permits and construction under one roof: design-build, led by a licensed general contractor with a degree in architecture, so the drawings are buildable and the price holds. One licensed team from the first lot read to the keys.
Nightly photos and comments from the crew in your project portal, the schedule and milestones, invoices and documents, and your questions answered within one business day.
Hours: By appointment. Finishes, plans and the design studio in person. Call or email first, and bring everyone who decides.
Call or text, 9 AM to 5 PM. You reach the people who build it.
Project and partnership inquiries go to Taron directly.
