Testimonials

5/5

We had no idea how much it cost to build ADUs when my mother in law came to stay with us. We all desperately needed our own space and speaking to the team put our minds at ease as it was actually affordable to have an ADU done. Plus the process was so unbelievably simple. The team listened to what we needed and everything was done on time and within budget. She loves her new space and now we are all happy with our privacy.

We chose Valley Boutique Builders for our home remodeling project, and it was the best decision we made. Their knowledge, skill, and personal attentiveness were evident from the start. They guided us through the entire process, offering valuable insights when we wanted something that wouldn’t be to their standards and they delivered outstanding results. Our home’s new look is just wonderful and we couldn’t be happier.

FAQ Section

An Alternative Dwelling Unit, or ADU, is a self-contained living unit that is secondary to the main house on a residential property. It is also commonly known as a granny flat, in-law suite, or backyard cottage. ADUs are designed to provide additional living space and can be used for various purposes, such as housing family members, generating rental income, or serving as a home office or guest house. The key difference between an ADU and a traditional home addition is that ADUs are separate living units with their own entrance, kitchen, bathroom, and utilities.

Yes, obtaining a permit is necessary for building an ADU in the Bay Area. The city of San Jose requires that all ADUs meet the California Building Code and the San Jose Municipal Code. As experienced contractors, we have a thorough understanding of the local regulations and building codes. We can guide you through the permit application process, ensuring that all necessary documentation and requirements are met to obtain the required permits

The price of a permit for an ADU can vary depending on several factors, including the size and complexity of the project. Permit fees typically cover plan reviews, inspections, and other administrative costs. At Valley Boutique Builders, we work closely with our clients to provide accurate cost estimates, including permit fees, during the preconstruction phase. Our goal is to ensure transparency and help you make informed decisions about your ADU project.

The cost to build an ADU can vary based on several factors, such as the size, design, materials used, and site-specific considerations. While each project is unique, building an ADU is generally a cost-effective way to add living space to your property compared to traditional home additions. Our team of experts at Valley Boutique Builders will work closely with you to understand your goals and budget, providing you with a detailed cost estimate tailored to your specific project. We strive to deliver exceptional value by optimizing the design and construction process to ensure your ADU is built within your budget.
