Our Approach: Backyard Houses the MyKabin Way


MyKabin only builds DADUs and our singular focus is to do this best.


We handle 100% of the building process – all you need to do is the fun part.


All of our DADUs are built to the Built Green 4-star level (full certification optional) and use locally sourced materials wherever possible.


We go the extra mile to give you clear, transparent pricing up front.


Our DADUs are affordable by design, yet semi-customizable for a personalized backyard home that costs less than our competitors.


Our process enables us to build quickly and give you the option to upgrade later to a fully functional DADU.

Better Systems and a Better Process Make Better DADUs


Driven to deliver great customer experiences, we make homebuilding a fun, hassle-free process. More than just a DADU builder, we are a team of passionate, customer-focused professionals.


We utilize a locally sourced green building product for our floor, walls, and roof structure that has a solid core of graphite-infused polystyrene insulation, resulting in a more comfortable, energy efficient space than traditional construction.


Installation is core to our design. By using local resources and suppliers, and our unique low environmental impact foundations, we average 33% lower construction time than other DADU builders.

Build a DADU in Your Backyard

We’ll send you a no-obligation feasibility assessment to see if your property can accommodate a DADU.

We will never spam, sell, or share your personal information with any third party (we hate that too).
