Affordable ADU Construction Services from Experienced Professionals

Whether you are looking to add an extra living space, generate rental income, or house family members, an accessory dwelling unit (ADU) can provide many benefits. However, taking on an ADU project requires working with trusted ADU contractors who understand the unique design and construction challenges. As one of the top ADU builders in the Bay Area, Open Concept Renovations has the expertise to deliver high-quality ADUs on time and on budget.

Renowned ADU Contractors with Extensive Experience

As licensed and insured ADU builders, we have successfully completed hundreds of accessory dwelling unit projects across Northern California. Our professional and experienced team has worked on a variety of ADU types, from small studio apartments to two-bedroom casitas. No matter your specific needs, we have the proven track record and qualifications to handle your project. Over the past decade, we have established ourselves as reliable ADU contractors that clients can depend on for all phases of development.

Complete ADU Services Tailored to Your Needs

Rather than acting as general contractors who hire various subcontractors, our team handles every detail of the ADU building process in-house. This vertical integration allows us to carefully manage all ADU construction services, from design to permitting to finish work. We offer a comprehensive portfolio that includes ADU design and build, remodeling, and construction project management. Whether you need help with initial planning, structural changes, or full-scale development, we have the capabilities and skills to guide your project from inception to completion.

Professional Design and Permit Assistance

Obtaining the necessary permits can often bog down an ADU project if not done correctly from the start. With our professional expertise in navigating city codes and regulations, we can expedite the permitting process. Our licensed architects are adept at 3D modeling and ADU design to maximize space within local guidelines. We also handle all liaison work with planning departments and commissions. You can have peace of mind knowing our ADU builders have the qualifications and proven track record to shepherd your project through the approval process.

Within Budget custom ADU Construction

One of the biggest concerns with any construction project is going over budget. Using pre-engineered plans and modular building techniques, we specialize in affordable ADU building. We provide detailed cost estimates upfront and stick to our proposed budgets, which allows clients to plan expenses accordingly without financial surprises down the line. Our attention to quality craftsmanship and efficient project management also helps minimize costs. You’ll love the end results without wanting to break the bank – that’s our promise as experienced ADU contractors.
