ADU Construction
Custom Accessory Dwelling Units built to LA code, from permits to final walk-through.

We design and build beautiful, code-compliant ADUs that add real value to your property. From detached units to garage conversions, our team handles the full process — design, permits, construction, and finishing.
Every adu construction project at KMBJ starts with a free in-person consultation. We listen first, then put together a detailed scope and a transparent estimate so you know exactly what you're getting and what it costs — no surprises.
Once work begins, you'll have a single point of contact, daily progress updates, and a clean, organized job site. We don't consider a project complete until you've done a final walk-through and signed off.
What's included
- Detached, attached & garage-conversion ADUs
- Architectural design & City of LA permits
- Foundation, framing, and turnkey finishes
- Energy-efficient mechanical, electrical, plumbing
