Every ADU begins with a story. Sometimes it’s a family looking for a place where a parent can live independently but nearby. At Jackson Design Build, we believe additional space should feel like it’s always belonged. We transform underused areas into refined living environments, whether that means creating a guest suite, a rental opportunity, or a retreat just steps from your door. Every project begins with a conversation — about lifestyle and vision. ADUs involve unique planning considerations, utilities, setbacks, egress, ventilation, structural assessments, and parking. We guide homeowners through these requirements in plain, accessible language, turning what could be a confusing checklist into a clear, collaborative roadmap.
Building an accessory dwelling unit is an opportunity to expand the way your home supports your life at a whole new scale. We specialize in full-site development, complex layouts, and long-lasting materials that harmonize with your home’s architecture. Natural light, custom floor plans, elevated finishes, and thoughtful flow define every project. During this phase, we also evaluate zoning constraints, fire-separation requirements, and mechanical loads, translating regulations into clear explanations so homeowners understand the “why” behind each design choice. There’s a certain artistry in creating spaces that feel meaningful and expansive. Even when the footprint is modest, the design demands more — every detail has to work harder, and clear communication ensures each decision supports long-term performance.
An ADU is often the most flexible square footage a property can offer. We help you envision how each element can serve both function and comfort while maintaining the sophistication of the main home. Our team guides you through layouts, materials, and selections so you can clearly imagine the finished result.
A successful ADU conversion requires an understanding of structure, systems, and space — and the ability to reconfigure them without compromise. Whether we’re executing full-scale transformations or constructing custom pole barns that blend performance with design, Jackson Design Build leads with architectural integrity and disciplined construction. Each phase unfolds with measured precision: structural tie-ins handled thoughtfully, utilities coordinated seamlessly, and craftsmanship aligned with the standards that define your home. The result is more than a renovation; it’s an expansion of what your property can become.
An accessory dwelling unit or conversion is more than a construction project, it’s a way to make your home more versatile, valuable, and deeply personal. As construction nears the finish line, there’s always a moment when the ADU feels complete for the first time, morning light stretching across new flooring, clean lines connecting one function to another, and a sense of independence built into the layout. Jackson Design Build creates spaces that feel complete and independent, not simply repurposed. Every project is built to meet the demands of long-term living, multi-generational needs, and high-end residential standards. These units aren’t side projects; they become meaningful extensions of your property — thoughtful, durable, and designed with the future in mind.
Craftsmanship that speaks for itself, trusted by homeowners and businesses alike.

We did a major addition to our home in 2024 which included a primary bedroom suite, kitchen remodel and opening up our living space. Jackson Design and particularly Billy Jackson who we worked with on a daily basis did an excellent job in working with his subs and vendors. The project was completed in a timely manner with absolutely no delays. We were truly happy in going with Jackson Design after having talked to several contractors and would recommend them and use them again if the opportunity does arise.Posted on Veeru DandavatiTrustindex verifies that the original source of the review is Google.

Recently, I toured some projects of Jackson Design Build. As a builder, now retired, I see many things most people do not on these projects. From the initial designs thru the execution and finish, JDB is very attentive to detail. The fit and finish of their product demonstrates quality and skilled craftsmanship. Bravo to Dave, Billy and their craftsmen.Posted on D. PateTrustindex verifies that the original source of the review is Google. I have known Dave and Billy Jackson for many years.

Having known the Jackson's for years through various industry groups and working with them, I've always been impressed with their honesty, integrity, and commitment to producing a high quality product. The fact that they are pleasant to deal with is a nice plus.Posted on Eric HansonTrustindex verifies that the original source of the review is Google. We were first-time home builders when we first engaged JDB and little did we know what we were getting ourselves into! But JDB was there to guide us from day 1; starting with acquiring a piece of land. Dave worked with us for 6+ months to design the house of our dreams and Billy then built those dreams into reality. The design/build process is long an arduous, but JDB was there throughout the entire process to provide guidance and insight. We absolutely love the finished product and couldn’t be happier with our selection of JDB to bring our dreams into reality.Posted on William Keener
