Process
Simple enough to trust. Detailed enough to build.
01
Evaluate
We start with your lot, goals, access, utilities, and the questions that shape feasibility.
02
Design
Custom plans, engineering, and finish direction are coordinated around the property.
03
Permit
We manage plan-check coordination and keep the next decision visible.
04
Build
A local team carries the project through construction, inspection, and handover.
Local service areas
ADU planning for specific LA neighborhoods.
Each area page connects ADU design, permits, garage conversions, and construction to local planning context, access, utilities, and the property questions homeowners actually run into.

Compact spaces with a serious point of view.
Why homeowners start
More ways to use the property you already own.
The right ADU can support family, guests, work, rental flexibility, or long-term property strategy. The plan starts with the site, not a generic package.
Family flexibility
Create independent space for parents, adult children, guests, or a future rental path.
Property-first planning
Understand size, access, privacy, and utility considerations before committing to a direction.
One accountable process
Design, permits, and construction stay connected instead of becoming separate handoffs.
Questions
What homeowners ask first.
The honest answer starts with the property, not a preset plan. We look at the lot, access, existing structures, utility questions, privacy, parking, jurisdiction, and how you want to use the space before recommending a detached ADU, attached ADU, garage conversion, JADU, or a different path.
