ADU Kits

What is an ADU Kit?

 

Accessory dwelling units—or ADUs—have surged in popularity in recent years, emerging as a top selection on short-term rental sites like Airbnb, Vrbo, and Booking.com. While many are designed as detached guest suites, granny flats, or tiny homes, ADUs offer far more versatility than just serving as private lodging. With an ADU kit from DC Structures, you can transform your vision into reality—whether that means building a profitable vacation rental, a comfortable space for visiting family, or something entirely your own.

How it Works

Our Process

Every great ADU starts with a conversation—one where our dedicated project coordinators take the time to understand your vision, goals, and priorities. From that first discussion, we work with you step by step to shape your ideas into a clear, buildable plan.

What We Offer

Our ADU Expertise

Permitting Support

Permitting for ADUs can vary dramatically from state to state — and even between counties and cities within the same state — making it crucial to understand local requirements early in the process. As seasoned experts in ADU design and construction, we’ll guide you through the permitting landscape step by step, helping you anticipate potential challenges and streamline approvals so your project starts smoothly and stays on track.

Flexible Designs

Our flexible design capabilities put you in complete control of your ADU’s look, layout, and function. Using advanced 3D modeling software, we’ll bring your ideas to life in an immersive digital environment, allowing you to explore and refine every detail—from wall placement and rooflines to windows, doors, and more—before construction ever begins.

Premium Upgrades

While many pre-designed ADU plans offer a one-size-fits-all solution, our approach ensures you never have to compromise on your vision. With an expansive selection of options and upgrades, you can transform your base kit into the perfect backyard cottage, guest suite, or creative studio—one that reflects your style, meets your needs, and enhances your property for years to come.

ADU Kit

Frequently Asked Questions

Our base ADU kits come with everything you need to efficiently and successfully assemble the frame of your ADU, including pre-cut, pre-drilled framing lumber, sheathing, siding, hardware, and more. From there, our wide range of options and upgrades lets you take your project even further, adding decorative details, structural features, and premium materials that make your ADU truly one of a kind.

Absolutely. Every DC Structures ADU kit is designed to be fully customizable to your vision, ensuring the final result reflects your style, site conditions, and lifestyle needs. Many clients begin with one of our pre-designed plans as a starting point, but we can also develop fully custom ADU plans based on existing drawings, concepts, or inspirations you provide.

Permitting requirements for ADUs can vary significantly depending on your location, so it’s important to contact your local city or county office early to understand the process. In most cases, you’ll need to submit stamped plans and related documentation before construction can begin. Our team is here to guide and support you through this process, helping you anticipate potential challenges and streamline approvals so your project stays on track.

Yes, you can absolutely assemble the kit yourself—and many of our clients do, especially for smaller structures like ADUs, pavilions, and pergolas. That said, if you prefer to work with a professional, we can connect you with a trusted contractor in your area through our nationwide builder network to ensure your project is completed smoothly and efficiently.

Prefabricated ADU kits offer unmatched adaptability, speed, and precision compared to traditional construction methods. Our flexible floor plans and precision-engineered components make it easy to create a custom structure that fits your property and comes together quickly and accurately on-site. In fact, prefabricated builds typically require 30% to 50% fewer framing hours than conventional builds. They’re also far more sustainable, significantly reducing material waste throughout the process and ensuring you enjoy a high-performance structure built to last for decades.
