Adu construction in California

California, with major metros like Anaheim, Riverside, and Sacramento, is a prime location for ADU construction. The state's diverse climate ranges from hot inland areas to cooler coastal regions. This variation influences building seasons and material choices. Navigating California's specific ADU laws is essential for success.

Choose your city

California has made significant efforts to streamline ADU development. State laws often override local restrictions, making it easier to build. However, local jurisdictions still manage permitting and inspections. The varied climate means construction can often proceed year-round, though extreme heat in places like Riverside or Santa Rosa can impact outdoor work. Many California homes are older, and adding an ADU may require upgrades to existing utilities. Choosing a builder experienced with these unique housing stock challenges is vital.
