ADU
An accessory dwelling unit changes how your whole property works. It’s a rental, a home for aging parents, a place for adult kids to land, or a quiet office set back from the main house. But only if it’s built and finished right. Kingswell connects you with vetted ADU pros who understand one thing better than most: a project like this has to stay fixed, stay dry, and stay on budget. One guarantee covers the work. One phone call gets it started. And because every Kingswell location is independently owned and locally staffed, you’re not working with a call center. You’re working with neighbors.
What’s Included
Every ADU project pulls in more than one trade, which is exactly why a family of twelve focused home-service brands matters. Here’s what a typical ADU build or upgrade involves, and how Kingswell handles each piece.
Site Assessment and Planning
Before anything gets built, someone has to look at the actual ground. Slope, drainage, setback rules, utility access. A Kingswell pro walks the property with you and tells you plainly what will work and what will fight you. You get a clear written scope before any commitment, not a vague handshake and a hope.
Foundation and Concrete Work
An ADU sits on its own foundation, and that foundation is not a place to cut corners. Poor drainage or a rushed pour shows up as cracks and moisture within two or three winters. Our concrete and site-work pros prepare, form, pour, and finish so the slab underneath your ADU is as dependable as the one under your main house.
Framing and Structural Work
Framing determines whether doors close properly in year five and whether the roof carries a heavy snow load without sagging. Our framing crews work from engineered plans and build to code, not to what’s fastest. Straight walls and square corners aren’t details. They’re the whole point.
Electrical and Panel Work
An ADU usually needs its own subpanel, separate circuits, and in many cases a service upgrade at the main panel. This is genuinely dangerous work if handled by someone who learned it from a video. Kingswell uses trained, licensed electricians who pull permits and test every circuit before anything gets covered up. We do not advise homeowners to touch panel wiring themselves.
Plumbing and Drain Lines
A kitchenette or full bathroom means supply lines, venting, and drain runs tied into the existing system. Bad pitch or a poorly vented drain will smell and back up eventually. Our plumbers pressure-test lines and inspect drains before walls close, because fixing a leak behind drywall costs ten times what it costs to do it right the first time.
Insulation and Drywall
A poorly insulated ADU is a box that’s hot in July and freezing in January. We install insulation to local code minimums, often exceeding them where it makes sense for comfort and energy cost. Drywall hung by hand, taped properly, and sanded clean means walls that look flat and accept paint evenly for years.
Flooring, Trim, and Finish Work
The final stretch is where quality either shows or hides. Level flooring, tight casing, clean caulk lines, hardware that’s set square. Our finish carpenters and flooring crews handle this phase with the same written guarantee as the structural work. You walk through at the end and it looks and feels like a finished home, because it is one.
Why Homeowners Choose the Kingswell Family
Kingswell is a family of twelve home-service brands, each focused on one trade. It was put together in 2026 around one idea: people do not want the cheapest repair, they want the one that stays fixed. Most homeowners calling about an ADU have been let down before somewhere along the line. A no-show. A price that changed at the door. A repair that failed a month later. The Kingswell name comes from the old king’s well, the shared well a whole town relied on, the one somebody always kept in working order. That’s the posture we try to keep. Every Kingswell company works to the same written guarantee, and every location is independently owned and operated. We don’t pretend to be from every town. Each shop is a local business that agreed to work to the Kingswell Guarantee: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If it fails inside the guarantee period, we come back and fix it at no charge. Fixed right the first time, and guaranteed in writing. That’s not a slogan. It’s the only way we’ve found to earn the next call.
Frequently Asked Questions
Most ADU projects can begin with a site assessment within a few business days of your call, depending on the season and our local schedule. Full construction start dates depend on permits and material availability, which we lay out plainly before you commit. Call us to get a real timeline for your specific property.
Each Kingswell location is an independent local business serving its surrounding neighborhoods and nearby towns. Because every location is rooted in its own community, the people who show up know the local building rules, the soil conditions, and the weather patterns that affect an ADU. Call us and we’ll tell you right away if we cover your address.
No. The Kingswell Way includes one non-negotiable rule: say the price before the work. You’ll receive a written price before any ADU work begins, and that number is what you pay unless you ask us to add something outside the original scope. Any changes get their own written price first. Call for a free estimate and a number you can actually plan around.
The Kingswell Guarantee is in writing and covers the workmanship on every trade that touches your ADU. If a repair fails inside the guarantee period, we come back and fix it at no charge. No fine-print runaround, no “that’s technically a different issue” conversation. You get the guarantee details on paper before work starts. Call us to talk through exactly what’s covered for your project.
