ADU construction from plans to final inspection.
An ADU is a small house. It has a real kitchen, a real bathroom, its own plumbing, electrical and HVAC, and it goes through the same permits and inspections. In a small space a planning mistake is hard to hide, so the layout and storage have to be worked out before construction starts.
As ADU builders in Los Angeles, we handle the whole process. We check your lot's setbacks and utilities, draw the plans, get state and city permits, build the unit, and make the space-saving kitchen and built-in storage in our own shop. Good storage is a big part of why a few hundred to about a thousand square feet can feel like a full home. California's ADU laws have made approvals much more predictable, whether you want a detached unit, a garage conversion or a junior ADU for family or rental income.

What we build
Four types of ADU we build.
Detached ADUs
A new standalone unit, often a few hundred to about a thousand square feet. A good fit for rental income or for family who want their own place, planned around the actual shape of your backyard.
Garage conversions
Often the fastest and lowest-cost ADU. We turn your existing garage into a legal unit with a kitchen, bath, insulation and proper systems.
Attached ADUs
An addition with its own entrance. It shares a wall with the main house but works as a separate unit.
Junior ADUs (JADUs)
Up to 500 sq ft built inside the existing home, with an efficiency kitchen. It's the smallest option and is often paired with a detached ADU on the same lot.

Cost
What an ADU costs in Los Angeles.

Every project is different, so we don't use a price list. Tell us about yours and we'll give you a range that fits your home. It's free and takes about two minutes.
- A realistic range for your specific scope
- What will move your number up or down
- A first range from your answers, before any visit
What drives the cost.
- New build vs conversionA garage conversion reuses the existing foundation and walls. A detached unit is built from the ground up. This is the biggest difference in the budget.
- Utility connectionsHow far the sewer line runs, the water line, and especially your electrical panel. Many older LA homes need a panel upgrade to support an ADU.
- Size & wet roomsSquare footage matters, but the kitchen and bathroom carry most of the cost per square foot.
- Site access & slopeA flat backyard with side access costs less to build on than a hillside lot where materials have to be carried in by hand.
- Finish levelA rental unit and a unit for family use usually get different finishes. We plan to the use you pick.

“We hired this team to convert part of our garage into a laundry area, a guest bathroom, and a shower. They did an amazing job! The tile work, wood accent walls, and vanity turned out great. The guys worked very clean and neat, kept the place tidy every day, and finished everything on time. Highly recommend them!”
