Licensed construction
Work With a Licensed ADU Contractor in Los Angeles
Construction should be handled by a properly licensed contractor with a clear scope and ADU experience. LADU coordinates vetted, licensed construction partners while your project manager keeps design, permits, field progress, and inspections connected.
A Licensed Construction Partner
Your build is assigned to a licensed construction partner suited to the plans, site, and construction method. LADU remains involved so you don't have to manage the handoff to the field.
One Point of Accountability
Instead of chasing separate ADU contractors in Los Angeles, you work through one project plan. Your project manager coordinates the team, tracks milestones, and answers questions.
A Visible Scope and Schedule
Clear estimates, material choices, milestones, and field updates help you understand the work without losing sight of the approved design or budget.
Our process
From Architecture and Permitting Through ADU Construction
A successful ADU depends on each phase preparing the next. LADU connects architecture, engineering, permitting, procurement, construction, inspections, and handoff in one project plan.
1
Feasibility, Architecture, and Engineering
The process begins with a property visit and review of your space, goals, access, utilities, and local requirements. The design team develops the layout and technical plans for permit review.
2
Permit Submission and Corrections
LADU submits the plan set, responds to jurisdiction comments, and shows permit activity in your dashboard. You don't have to relay information between the designer and permit office.
3
Procurement and Construction
After approvals and preconstruction decisions, LADU coordinates the build with a licensed construction partner. Your project manager tracks milestones and field reports as the structure, systems, and finishes come together.
4
Inspections, Walkthrough, and Keys
The team coordinates inspections, completion items, and the final walkthrough, creating one path from early design decisions to a finished, permitted ADU.
How it works
From site visit to keys in 8 to 14 months.
The same six-phase plan runs every LADU design & buildproject. Your dashboard shows exactly where you are, every step of the way.

Choosing an ADU team
What To Look for in a Los Angeles ADU Company
The best company for an ADU in Los Angeles isn't simply the one with the biggest promise. Compare ADU companies based on responsibility, proof, cost, communication, and the path from plans to final inspection.
Licensing and Insurance
Confirm who will perform construction, verify the contractor's active license and insurance, and ask whether subcontractor responsibilities are documented.
Local Permit Experience
Look for a team that understands Los Angeles-area planning review, correction cycles, inspections, and jurisdiction differences. Local experience should be visible in its process and record.
A Complete, Written Scope
Ask what's included in feasibility, ADU design services, engineering, permits, site work, utilities, finishes, inspections, and closeout. The proposal should explain allowances, exclusions, and change orders.
One Accountable Process
Some accessory dwelling unit builders in Los Angeles provide only plans or construction. For design-build, confirm who coordinates each phase and handles questions that cross from design into the field.
Clear Costs and Milestones
Compare the estimate, payment milestones, material selections, and treatment of site conditions. Transparent assumptions are more useful than a low number with an unclear scope.
Relevant Proof and Communication
Review comparable projects, permit results, timeline reporting, warranties, and communication tools. A credible ADU company in Los Angeles should clearly show its experience and management process.
