The first step

Transforming your property

Feasibility research will be the first setup for the process of planning and building an Accessory Dwelling Unit (ADU). We will carefully evaluate your property, local laws, and overall goals to determine the best potential placements and sizes of your future ADU, working to highlight the unique opportunities that your property can provide.

Discovering the potential

According to local laws and regulations, and current labor and price factors. We’ll then conduct an ADU feasibility study to determine the scope of work. We’ll provide cost estimates, timelines, financial projections, and a preliminary site map– all compliant with local regulations.

ADU Design & Engineering

Based on the building code, and local regulations, you need to provide a full set of plans for city review. So that why we can handal for you. Collaborate with our project-coordinator and designers to customize your ADU. We ensure that the final configuration not only reflects your vision but also meets site-specific requirements and comply the building code.

City Permitting

How much does it cost to build an ADU ?

Every ADU is different, depending on the complexity of each project, different materials are used.

With the many variables that go into building an ADU, it can be difficult to determine the potential cost, but...

There are sample of "rough quotes" for your reference ( year of 2025 ) :

For existing Garage-conversion: between $ 190 / sf~ $ 220 / sf. 400sf (2-car) garage can cost between $76k ~ $88k.
New-build structural (attach / Detach), Cost between $ 250/ sf~ $ 280/ sf and up

We’re committed to providing accurate information. Through our feasibility study, you’ll receive approximate costs for each option to help you in your planning and budgeting process.

How long does it take to build an ADU ?

From the beginning of the design phase to getting keys in hand for a completed ADU,

the average ADU project timeline is around 6 ~14 months.
Keep in mind that timelines can vary depending on terrain, how many units you plan to build, permitting turnaround time, and other factors.

Our feasibility studies break down an estimated timeline based on your property and goals, showing expected due dates and other important milestones.
