Increased Property Value

Adding an ADU to your Bay Area property can significantly increase its value, even up to 30%. The demand for housing in the San Jose region is high, and the addition of an ADU provides a desirable feature for potential buyers or renters. ADUs offer a separate living space that can be utilized for various purposes, such as a rental unit, a guest house, or a home office.

Flexible Living Space

ADUs offer homeowners the flexibility to accommodate changing living arrangements and evolving family needs. Whether you have elderly parents, adult children, or extended family members, an ADU provides a self-contained living space that promotes independence and privacy while keeping loved ones close by. ADUs allow for flexible living arrangements that can adapt to different stages of life, ensuring a comfortable and harmonious living environment for everyone involved.

Our Process

Discovery

Every engagement starts with an in-home consultation meeting to discuss your goals, desired results, and budget for your unique ADU. With your input, we create a specific project’s scope and agreement.

Preconstruction kicks off with sessions to uncover the details of usage, color, light, and texture to create a space that thrills you. This phase includes material selection, planning, and permits relevant to the Bay Area.

Development

During the development phase, our expert team at Valley Boutique Builders manages every detail of the construction process, ensuring a seamless and efficient progression of your project.

faq

An ADU, or Alternative Dwelling Unit, is a separate residence located on the same property as the primary house. ADUs are built to provide extra living space and have several potential functions, including but not limited to: housing family members, generating rental income, operating as a home office, or accommodating guests. An ADU is distinct from a standard home addition in that it functions as an independent living space, complete with its own front door, kitchen, bathroom, and utilities.


The cost of a permit for an ADU in San Jose 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.
