What Is an ADU and Why Build One in the Santa Clara?

An Accessory Dwelling Unit (ADU) is a small, self-contained home built on the same property as a primary residence. ADUs can be a backyard cottage, a garage conversion, or even an addition to your existing home. They are designed to provide extra living space, whether for family members, rental income, or personal use.

In Santa Clara, ADUs are especially popular due to the high cost of housing and the need for flexible living arrangements. By building an ADU, homeowners can:

- Add extra living space for family, guests, or tenants.

- Generate rental income to help cover mortgage costs.

- Increase property value with a versatile addition.

- Provide a housing option for seniors, young adults, or others needing an affordable home.

Santa Clara’s updated zoning laws and streamlined permit processes have made it easier than ever to build ADUs. With space at a premium, ADUs are a smart and sustainable solution to create more housing in your community.

They also helped us to procure the materials and consulted us about the nuances of different kinds.

This construction company is the definition of excellence!! They take their time to make sure the end product is exactly what you want it to be!! I couldn't be happier with the work I got done. The service is amazing!! The value of the work is amazing! The wall had texture and everyone was looking for shortcuts to design the wall. But this company doesn't believe in short cuts. They made the wall smooth which took some time and then created the design to give it the look I wanted!! My daughter's nursery is looking amazing because of this wall.
