Our ADU Construction Process

Step 1: Property Assessment

We evaluate lot size, setbacks, utility access, and zoning compliance for your property. In Los Angeles, homeowners must submit plans for ADU projects to their local department of building and safety, which may require detailed blueprints and measurements. Our team provides recommendations for optimal ADU type and placement based on your specific site conditions.

Step 2: Design and Planning

We create custom ADU designs based on your needs and budget, collaborating on layout, finishes, and architectural style. Design-Build firms handle everything from architecture to construction in ADU projects, streamlining the process significantly.

Step 3: Permit Acquisition

We handle all permit applications and city approval processes. Local contractors should be familiar with navigating the Los Angeles Department of Building and Safety’s permitting process. The City of Los Angeles offers an ADU Standard Plan Program where certain plans are pre-approved for code compliance, which can expedite the permitting process.

Step 4: Professional Construction

Licensed contractors build your ADU to exact specifications with regular progress updates and quality control inspections. ADU construction in California requires a written Home Improvement Contract that includes a clear scope of work and project timeline. In California, contractors cannot legally ask for a down payment of more than $1,000 or 10% of the total cost, whichever is less.
