Build More Possibilities Into Your Property
Adding an accessory dwelling unit can create valuable new living space without leaving the property you already call home. Whether you’re planning a private space for family, a guest house, a home office, or a flexible living area for the future, the right ADU starts with thoughtful planning and experienced construction.
Pro Builders and Design provides professional ADU construction in San Diego and the Bay Area, helping homeowners turn underused areas of their properties into comfortable, functional living spaces.
With more than 20 years of construction and remodeling experience, our team brings careful planning, quality craftsmanship, and clear communication to every ADU project.
From the initial concept through construction and the final walkthrough, our goal is to make building an ADU feel organized, understandable, and exciting.
INSPIRED BY VISION. BUILT WITH PRECISION. FINISHED WITH CARE.
Our portfolio reflects decades of experience creating homes and spaces with thoughtful design, dependable craftsmanship, and attention to every detail.
Find the Right ADU for Your Home and Lifestyle
Every property is different, which means every ADU project deserves an individual approach. Lot size, existing structures, access, utilities, architecture, intended use, and your long-term plans can all influence the right design.
Our experienced ADU contractors work with homeowners to explore solutions that make sense for both the property and the people who will use the new space.
Detached ADUs
A detached backyard ADU can create a completely separate living environment with greater privacy and independence from the main residence.
Attached ADUs
An attached ADU can provide additional living space while integrating thoughtfully with the layout and architecture of your existing home.
Garage Conversions
An existing garage may offer an opportunity to create usable living space within your property’s current footprint.
Custom ADUs
For properties with unique layouts or homeowners with specific goals, we can develop a custom ADU solution around your needs, preferences, and property.
Not sure which option makes the most sense? Our Design & Plans services can help turn your initial ideas into a more clearly defined project.
Quality Work. Happy Clients. Beautiful Results.

One Experienced Team From Concept to Completion
Building an ADU involves much more than constructing four walls. A successful accessory dwelling unit requires coordination between design, planning, structural work, site preparation, utilities, construction trades, interior finishes, and exterior details.
Pro Builders and Design brings those pieces together through one organized construction process.
Depending on your project, our ADU construction services can include site preparation, foundation work, framing, roofing, electrical, plumbing, HVAC, insulation, drywall, flooring, cabinetry, kitchen installation, bathroom construction, interior finishes, and exterior improvements.
Having an experienced construction team involved throughout the project helps maintain continuity between what was originally envisioned and what is ultimately built.
If adding onto your existing home may be a better fit than building a separate ADU, explore our Home Addition services.
A Clear Process From Your First Idea to Your Finished ADU
A well-planned project creates a better construction experience. We guide homeowners through each stage so they understand what is happening and what comes next.
1. Consultation & Vision
We start by learning about your property, goals, intended use, priorities, design preferences, and budget so we understand what you want your ADU to accomplish.
2. Design & Pre-Construction
Our team works through the design, project details, plans, material considerations, and other pre-construction requirements needed to prepare the project for building.
3. Construction & Project Management
Once construction begins, our experienced team coordinates the work while focusing on craftsmanship, organization, communication, and attention to detail.
4. Final Walkthrough & Completion
We review the completed ADU with you, address remaining details, and make sure your new living space is ready to enjoy.
If your plans involve improving much more than one portion of the property, our Whole Home Renovation services provide a more comprehensive approach to transforming your home.
