Accessory dwelling unit construction cost — Santa Clara, CA

The main difference lies in how they are regulated and their intended use. A room addition is simply expanding your existing home’s footprint, often for more living space. An accessory dwelling unit (ADU), however, is a secondary, independent living unit on your property, complete with its own kitchen, bathroom, and entrance. In Santa Clara, ADUs often have streamlined permitting processes and specific regulations designed to increase housing stock. The pros we work with can explain these nuances.

In Santa Clara, California, ADUs have specific size limitations defined by state law and local ordinances. Generally, attached ADUs can be up to 1,200 square feet, while detached ADUs can also reach this size, with specific rules regarding setbacks and lot coverage. The exact dimensions allowed can depend on your property’s lot size. The specialists can review your property and the latest city regulations to determine the maximum size for your ADU.

The primary disadvantage of building an ADU is the initial construction cost, which can be substantial. You’ll also need to consider how it might affect your property taxes and potentially increase utility bills. Ensuring the ADU fits aesthetically with your existing home and neighborhood is another consideration. However, the potential for rental income and increased property value often makes it a worthwhile investment. The pros can help you plan for these factors.
