It has never been easier to build an Accessory Dwelling Unit (ADU) in California. With the help of California SB 13, properties zoned for single-family residences are permitted to build at least one ADU on the property without the need to subdivide the parcel. Some larger properties are allowed to build multiple ADU's on a single property. Cities are expediting the permitting process, meaning less waiting to start construction. German Engineering Design has helped dozens of homeowners with the Structural Design of their ADU's. We make sure to earthquake retrofit any existing areas and design new areas for performance and cost efficiency.
