Site Visit


It all begins with a complimentary visit to your property by our experts. During this phase, we will determine whether your lot is eligible to have an ADU in accordance with the local building standards. If it is so, they will sit down with you to understand the layout, style, and features you desire in your new structure.


During this phase, we will work closely and take into consideration all the relevant factors to draft a plan for your ADU. The plan will depict all the details on and under the floor, including lighting, sewerage, piping, and plumbing systems.


Once the design is approved by you, we will proceed into the construction documents phase. Our structural engineers will develop a structural system for your ADU plan and work on other details that could potentially make an impact on the cost and timeline of construction before finalizing the draft.


Upon your approval, we will submit the design plan to the Building Department for a permit. We will remain available for follow-ups on any questions or plan reviews from the concerned authorities.


We offer a wide variety of ADU floor plans and finish options to let you customize new unit.

Garage Conversion

GARAGE CONVERSION: 400 Sqft - 500 Sqft

A garage conversion is the quickest and cheapest way to create a new space like a living room, an extra bedroom, as the roof, walls, and foundations are already in place. The building cost of this ADU is minimal when the garage has an electricity connection and has easy access to the sewer system.

ATTACHED ADU: 150 Sqft -1200 Sqft

An attached ADU unit is connected to the main structure of the home and typically shares the electrical system and the main sewer line with it. Over the garage and basement apartments are some examples of such types of ADUs.

Detached ADU

DETACHED UNIT: 350 Sqft - 1200 Sqft

A detached ADU is a second dwelling that is both physical and functionally separate from the main structure. Depending on your municipality and the size of your existing lot, you can build a detached ADU of up to 1,200 SF. A detached ADU may have its own address and utility connections.
