“I just finished working with Snap ADU on an investment property and highly recommend them. As a real estate investor, keeping on time and on budget is extremely important and SnapADU kept their promises on all fronts. From the very first meeting regarding the feasibility of my project to the final walkthrough on the completed units, the team surpassed my expectations. The entire process with SnapADU is seamless and they keep you informed every step of the way. As we worked through permitting with with city and began construction I always felt like I was up to date with everything going on. They really are a “one stop shop” and would not hesitate to hire them for my next project.” – Ricardo P., Investor in San Diego
Smart Design and Structure
This custom duplex ADU was designed to creatively use the available space and maximize the buildable footprint in San Diego. Each unit spans 1,200 square feet across two stories and includes three bedrooms and two bathrooms.
