Project Name Location Description
Your Project Anywhere in Orange County Accessory Dwelling Units (ADUs) you want done right!
Carr Horse Barn and ADU (22016)> Coto de Caza, CA New Horse Barn with ADU Above
Singer Residence (21917A) Laguna Beach, CA This project consisted of converting half an existing garage to an Accessory Dwelling Unit (ADU). The challenge with this project was the fact that the existing slab on grade did not have a moisture barrier. Working with the building official, a satisfactory solution was developed and the existing slab could remain.
Covington Residence (21826) Fullerton, CA Accessory Dwelling Unit (ADU) in the backyard of an existing single family residence. The challenge on this project is that the backyard has a slope down (about 24 feet) to an existing flood control channel. According to the code, existing structures need to be set back from the top of slope by a distance of H/3 or 8 feet. That would leave little room for the ADU. Instead, 8 feet of the slab was designed as a structural slab designed to cantilever off of a footing located the required H/3 from the top of slope
Del Toro Residence (21760) Laguna Beach, CA Accessory Dwelling Unit (ADU) addition to an existing single family dwelling. The challenge on this project was that it is located in an area of known landslides (Bluebird Canyon). The foundation consisted of a structural slab supported by cast in drilled hole (C.I.D.H.) piles. This made the project a little pricey, but, hey, this is Laguna Beach!
