ADU Contractor

We are the real hard workers

Thank you for visiting ADUPRO. We are committed to building safe, convenient, and beautiful homes for our valued customers.

The most important furniture in your house is SPACE.

We believe construction is not simply about assembling materials to build a structure—it’s about creating harmony. Every material should be thoughtfully placed, every detail carefully planned, to reflect your personal taste, needs, and lifestyle within your space.

A house is more than just a physical structure. It’s a sacred place where family comes together, where love, care, and connection create a true home. Like a nest, a home nurtures the soul and becomes the foundation for memories, growth, and belonging. Building homes with this deeper purpose in mind is at the heart of our philosophy.

As a full-service construction company, we handle everything from the foundation to the roof, including additions, ADUs, kitchen renovation, bathroom remodeling, even swimming pools—all at a cost that’s fair and affordable. Our team consists of skilled, trained professionals who are ready to bring your vision to life with care and precision.

If you have a project in mind, we would be happy to offer our professional insight and a no-pressure estimate. Our goal is to help you create a more beautiful, functional, and comfortable living environment—because we believe everyone deserves a home that supports their best life.

With appreciation,

Ken Lee

ADU Essentials

Cost of Building

Building an ADU or a home addition may not be technically difficult—but having a well-planned budget is absolutely essential.
From the initial planning and permits to construction and final finishes, every phase requires consistent funding. Without proper cash flow, the project could face unexpected delays or even come to a complete halt until sufficient funds are available.

We always recommend that homeowners prepare a realistic budget before starting any construction project, ensuring there’s enough financial support to carry the project through smoothly from start to finish. With the right planning, we can help you stay on track, avoid unnecessary stress, and achieve the results you’re hoping for—on time and on budget.

Standard of Quality

The final quality of any construction project is ultimately shaped by the builder’s standards.
A builder who holds a high standard for craftsmanship will naturally lead the project toward a superior outcome. However, true quality isn’t achieved alone—it is the result of strong collaboration between skilled workers and a committed builder who share a common goal.

When everyone on the team works with care, respect, and attention to detail, the end result reflects that effort: a beautifully built space that stands the test of time.

Construction Time

Constructing a living space or structure is both a complex and potentially hazardous process.
It requires careful coordination, experience, and a strong commitment to safety and precision. One of the most critical factors in ensuring a smooth and successful build is a well-structured timeline—tight enough to maintain momentum, yet flexible enough to allow for quality workmanship and unforeseen adjustments.

Proper time allocation helps prevent costly delays, keeps the project on track, and ensures that each phase is completed with care, not compromise. With the right planning and execution, we can deliver results efficiently—without sacrificing safety or quality.

Good Workers

Good, honest workers build great homes.
At the core of every successful project is a dedicated team. That’s why we treat our workers with the respect and dignity they deserve—regardless of their background—and compensate them fairly with generous wages.

This may sound simple, but it’s one of the most effective ways to build with lower risk and higher quality. When workers feel valued, they take pride in their craftsmanship, stay committed to safety, and consistently deliver their best. We believe that when we take care of our team, they take care of your home.

Revised Home For you

Before any physical construction begins, proper planning and approval are essential.
Navigating the requirements of the local planning department can be a daunting task for homeowners—but with our extensive experience, we understand the process thoroughly. Our expert team handles everything from preparing detailed plans to submitting all necessary documents to ensure a smooth approval.

Once the permits are in place, our skilled crew gets to work—following a well-organized and balanced schedule that minimizes disruption to your daily life. We coordinate every step carefully to avoid conflict with your routine while keeping the project on track.

In the end, we deliver a beautifully revised and functional home, tailored to your needs and lifestyle—crafted with precision from start to finish.

Get the Consultation

When you call us, we can provide an instant preliminary estimate using Google Earth Pro and advanced construction analytics tools.
We kindly ask that you reach out with an open mind. Building your project is not something accomplished by the contractor alone, but it requires mutual understanding and strong communication between both the contractor and the property owner. A successful project starts with both parties being on the same page.

We truly value meaningful consultations with our potential clients. In many cases, we’ve found that property owners may have misconceptions about the construction process—such as planning and building requirements, risks, budget expectations, or realistic timeframes. That’s why we place great importance on open, honest conversations early on, so we can fully understand the scope of your project and your specific goals.

With clear communication and mutual understanding from the beginning, we can help you build an efficient plan and realistic timeline, avoiding missed steps and costly surprises along the way. A positive, cooperative mindset is key to achieving the best results.
