What affects the price
Building an ADU involves several moving parts that shape your total investment. The final figure depends heavily on whether you choose a prefab unit or a custom build from the ground up. Site conditions are another major factor; if your property requires extensive grading, utility trenching, or foundation work, costs will climb. You also have to consider your choice of finishes, like high-end appliances or custom cabinetry. Navigating local permit fees and impact assessments also adds to the total.

Prefabricated ADUs can be a great option for many San Bernardino backyards, offering quicker construction times. These units are built off-site in a factory and then assembled on your property. This method can sometimes be more cost-effective and less disruptive to your daily life. However, it's important to ensure the prefab unit meets all local building codes and is suitable for your specific lot. Discussing this with experienced builders is key to making the right choice for your home.
