How Much Does It Actually Cost to Build an ADU in California?

Inside Our New ADU Showroom in Los Angeles

Because you deserve more than a rendering.

If you’re considering building an ADU in Los Angeles, this showroom gives you a chance to see the real thing—installed, staged, and ready to walk through.

At LiveLarge, we’ve heard it all:

    “I don’t trust computer mockups.”
    “Can I see something in person?”
    “I want to walk a real project—not just a model unit inside a warehouse.”

So we did the obvious thing:

We built a real, furnished, full-size 750-square-foot ADU—installed on a real lot, with working utilities, in the middle of San Marino.

This isn’t just a demo. It’s a real-world proof point. A space you can walk through, close the door, and feel what it’s like to live better. And while this showroom is in LA, it reflects the same quality and care we bring to every ADU project across Los Angeles.

What You’ll See in the LA ADU Showroom

Our San Marino showroom features the L-750 — a 2 bedroom, 2 bath ADU that’s been fully staged and thoughtfully designed for real-life living. Visitors can experience:

  • Whisper-quiet insulation and temperature control
  • Full kitchen and bathroom build quality—not cheapened for display
  • Real light, real air, real flow
  • Flawless finish work from our in-house construction team
  • A structure built like a fortress, but filled with light

It’s all there. No renderings. No CGI. Just what you’d actually get, installed on your lot as a real ADU in Los Angeles.

Why This ADU Showroom Matters

ADUs are about more than design—they’re about delivery.

Can it be installed quickly? With permits, power, water, and zero drama?

That’s the part most companies don’t show you.

We do.

This showroom proves the full stack:

  • We design it.
  • We build it.
  • We deliver and install it.
  • We handle the hard stuff, start to finish.

You’re not just buying a box. You’re trusting someone to make your life easier.

We want to earn that trust—with every ADU we build in Los Angeles and beyond.
