Add a Legal Second Unit

to Your Property

Recent changes in state law allow homeowners anywhere in California to build an Accessory Dwelling Unit (ADU) on your property-- a separate and 100% legal unit for rental income or for your family. 
Building Blocks builds beautiful, affordable ADUs on your property.  We can custom design an ADU up to 1,200sf, or build our classic 600sf 1-bedroom, 1 bathroom unit (see renderings and in-progress photos below).   
We provide all the services you need: design, permitting, and construction. 
Want to work with your own architect and/or contractor? We  also provide owner's representation services to make sure you're protected throughout the design, permitting, and construction process.
