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 in 2020 to meet the need for both standard and custom detached ADUs in San Diego.

  • We were looking at ways to invest our money. My wife and I thought, why don't we build an ADU for rental income? Also, someday we can move into it. So it has multiple purposes.

  • We decided to build an ADU because our family's property is a big lot. That's hard to find these days, especially with the cost of housing. Plus we are closer to my mom.

  • I decided to build an ADU because the property was a double wide lot. I'm a half mile from the beach and could see the view from the top of my house and thought, I have to take advantage of that.

  • I'm a product stylist and photographer. I decided to build an ADU because my business was taking off and I was spending a lot of time outside of the home. Building a studio lets me work from home more.

Why we love building granny flats

SnapADU Mission Statement: We make it approachable to thoughtfully add housing so our community can build flexibility and potential.

We get to help people and families come closer 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.
