We’ve chosen to bring design & permitting in-house to ensure our high standards are met… and to enable you to work with one company throughout the highly specialized project of building an ADU. And we are the only ADU contractor that offers a pricing guarantee to offer you predictability on your project.

Our Origin Story

We're 100% focused on being the best ADU builders in San Diego. We do this by having a deep understanding of construction, design, regulations, and business.

Our co-founders were both excited about changes in ADU regulations, while they brought very different perspectives to the company. Mike has spent his whole life in construction and built custom homes under his own general contracting license since 2013. Meanwhile, Whitney worked in the corporate world for over a decade honing management and operational skills. Together with an incredible team, they created SnapADU to meet the need for both standard and custom detached ADUs in San Diego.

Why We Love Building Granny Flats

“Built on a culture of prioritizing people, promoting transparency, pioneering innovation and providing flexible lifestyles, SnapADU designs, permits and builds high quality ADUs of unprecedented value by utilizing conventional construction methods amplified by cutting edge technology & processes.”

We get to help people and families come together... to live closer and be part of each others' lives daily, to bring aging parents closer to grandkids, to give handicapped dependents more independence, or to give young adults a chance to raise their kids in a community they might not normally be able to afford.

We also get to help people bring in rental income... money that helps them pay their mortgage, travel more, work less, or even retire sooner. We offer them flexibility, since ADUs are versatile and meet the demands of evolving lifestyles.

We plan and design with each client to make the best lifestyle choice for their family. What size ADU? Where on their property should it go? Which floor plan should they choose? How much will it cost? Does it make sense? We have respect for our clients and want to help them as they are considering options for their unique situation.
