We’re 100% focused on being the best ADU builders in San Diego. As a licensed general contractor, we take responsibility for the entire design, permit, and build process for your granny flat to ensure you have the predictability and accountability you need on the highly specialized project of building an ADU.

Representing the biggest chunk of your overall ADU costs, the build makes your ADU contractor the most crucial player in your project. We’ve chosen to bring design & permitting in-house to ensure our high standards are met for each client and enable you to work with one company for the entire process.

With a background in high-end custom homes and renovation in North County San Diego as Moore Construction since 2013, we’ve designed the SnapADU product & process to meet the need for economical, efficient, and attractive detached ADUs.

Why We Love Building Granny Flats

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.
