ADU Builder in Charlotte, NC — ADU Builder Since 2009

ADU Builders Charlotte NC

Most ADU builder calls we get in Charlotte come from one of two places. Either a parent is moving in and the family wants them close but not under the same roof, or a homeowner wants a separate space to rent out and help cover the mortgage. Both are common enough around Charlotte, Waxhaw, Weddington, and Marvin that we’ve built a real process around it instead of treating every ADU like a one-off.

Dream Home Builders and Remodelers has worked as an ADU builder in Charlotte since 2009, as part of our general contractor services. We’re a design-build company, meaning the same team that plans your ADU is the same team that builds it, handling the design, permitting, and construction under one roof.

ADU Builder in Charlotte, NC

An ADU, accessory dwelling unit, is a smaller detached living space built on the same lot as your main house. It’s basically a small, self-contained home: its own entrance, kitchen, bathroom, and living space, separate from the main house but still on your property. As an ADU builder, we handle everything from the site plan to the final walkthrough.

What Homeowners Use ADUs For

The two most common reasons we hear are aging parents and rental income. An ADU lets a parent stay close to family without living in the same house, with their own space and privacy. On the rental side, a detached ADU can generate income without changing how your main house functions day to day. Some homeowners also use one as a home office or a space for adult kids who aren’t quite ready to be fully on their own.

Whatever the reason, the starting point is the same: we look at your lot, talk through what you actually need the space for, and figure out a layout that fits both your goals and what the property can support.

Zoning and Permitting for ADUs in Charlotte

ADU rules vary by lot, by jurisdiction, and sometimes by HOA, so what’s allowed on one property in Charlotte isn’t automatically allowed on the next one over. As part of our general contractor work, we handle the zoning research and permitting so you’re not the one trying to decode local ordinances. We’ll tell you early on if your lot isn’t a good fit for an ADU, instead of taking your money and finding out halfway through design.

How Much Does an ADU Cost in Charlotte?

ADU builds in this market typically run $150 to $300 per square foot plus, depending on finishes, utility hookups, and how much site work your lot needs. A smaller, simpler ADU on a lot with easy utility access lands toward the lower end. More square footage, higher-end finishes, or a lot that needs significant grading push the number higher. We give you a real number after walking your lot, not a rough estimate over the phone.

How Long Does an ADU Build Take?

Most ADU projects take 4 to 7 months from permit to move-in, depending on size and how much utility work is involved. Zoning research and permitting usually add a few weeks to a couple of months before construction starts, since ADU permitting in this area often takes longer than a standard remodel permit. We build that timeline into the plan up front instead of it becoming a surprise.

Why Design-Build Matters for an ADU

An ADU is a full small structure, foundation, framing, plumbing, electrical, and finish work, built on a lot that already has an existing house and utilities to work around. When one team handles design and construction together, decisions about placement, utility hookups, and layout get made with the whole project in mind instead of a design that a contractor later has to figure out how to build.

ADU Building Across the Charlotte Area

We build ADUs across Charlotte, plus the surrounding towns: Waxhaw, Weddington, Marvin, Matthews, Fort Mill, and Lake Wylie. Larger lots in Waxhaw and Weddington tend to have more room and fewer constraints for an ADU, while in-town Charlotte lots often need more careful planning around setbacks and existing structures.

Otto was incredible to work with. Otto converted our detached garage and added an outdoor / covered patio to create an awesome indoor / outdoor living space. Otto is knowledgeable, easy to work with, and helped us navigate the many decisions that come with a home renovation. Thanks, Otto!

When we tell our friends we LOVE our contractor, they roll their eyes and tell us their horror stories. We are so incredibly pleased and lucky to have found Otto and Dream Home Builders and Remodelers. Honestly. We were new to the area. We knew no one. No ability to get recommendations for the major home and garage project we had planned. So we Googled. Insane right? Somehow Otto’s Dream Builders site stood out. Once we met Otto we knew he was the right contractor for us. Straight forward, enthusiastic and professional. He’s just a real and nice guy. We didn’t get any other bids. Insane right? We just went with our gut. And was our gut right! Otto and Dream Builders transformed our home. 1) Care taken as we did architectural drawings. Loved his recommended architect! 2) Easy and thorough estimate process. 3) Set expectations well. 4) Started when he said he would start. 5) His subs showed up when he said they would and they were all top notch. Felt safe and confident when we had 10 trucks in my driveway and people in my home. 6) His oversite was always there. 7) He responded to every call and every email. 8) Handled all permits and inspections. 9) The work was exceptional and exactly what we wanted. 10) He made our dream come true. - He designed and built a garage with a gorgeous family room above it. - Painted and roofed the entire exterior of home and new garage. - Renovated our dilapidated shed. - Concrete and rock work. If you are thinking about building or renovating, you should call Otto at Dream Home Builders and Remodelers.

We used Dream Home Builders (Otto) to build a 2 stall detatched garage with a mother-in-law suite (full studio apartment) above it. We live in the Myers Park area of Charlotte. Their team was great in helping make our ideas a reality on the project. We had a "rough vision" but Otto helped us at every step along the way with helpful suggestions and recommendations. He was never pushy, but let us know what the market trends and reasoning behind these suggestions were. We are preparing to remodel a bathroom in our house soon and have already tapped Dream Home Builders to do that project as well. The sign of a great builder is the willingness to use them again! Thanks Dream Home Builders / Otto, The McCorduck (Perkio) is greatly appreciative of the work you've done, we love the finished product.

Otto Anderson from Dream Home Builders recently renovated our primary bathroom in Charlotte, NC. From start to finish, he demonstrated professionalism, organization, and transparency, which made the process smooth and stress-free. One of the standout qualities was his organization. He kept the project on schedule and provided regular updates on the progress, ensuring that there were no surprises. His communication was clear and consistent, and he was always available to address any questions we had. We also appreciated his honesty and transparency about what was feasible within our space and budget. Rather than overpromising, he was upfront about what could and couldn’t be done and offered creative solutions to achieve the look we wanted without compromising quality. Regarding costs, he was clear from the start and provided a detailed breakdown of expenses. There were no hidden fees or unexpected charges, which gave us peace of mind throughout the project. The final result speaks for itself—our bathroom is stunning, functional, and exactly what we envisioned. We highly recommend Otto to anyone looking for a reliable, skilled, and trustworthy professional for home renovations. We will definitely hire him in the future!

We recently decided to renovate our kitchen in Matthews North Carolina. We cook every day and it is the central gathering place in our home. After doing research and interviews, we chose Dream Home Builders for the project. Otto came to our home to assess the project. Rather than tell us what we should do, he carefully listened to understand what we wanted. We were impressed that he brought all of the craftsman that would be involved in the project to our home on a single day to discuss and coordinate who would do what when. Once the project began, it flowed smoothly with no hiccups. With Otto‘s help, we chose an interior designer to help us select specific materials for the project. She worked well with Otto to see that our vision became reality. Our expectations were met and exceeded with regard to communication, quality workmanship, budget, smooth scheduling and finished product. Dream home builders has earned our whole-hearted recommendation.

Otto and his team with Dream Home Builders & Remodelers are one of the rare finds. I’m the daughter of a builder (not located in the same city) and am very picky about finding a true craftsman with quality work and attention to detail. Otto met the requirement! They did about 5 projects total for us, see below for more: -Converted our hot back patio into a beautiful covered and screened porch with a stone gas log fireplace, ceiling fans, and recessed lighting. We now enjoy our outside space versus baking in the summer sun! This including crown molding details both inside and outside that matched our current aesthetic -Created a ‘moms attic’ in our garage for storage and re-insulated our garage ceiling for better temperature control in our finished room above the garage -Converted our downstairs half bath into a guest bath with custom tile shower -Created and installed a 14’ custom shaker desk unit for 2 (hybrid work) and a shaker desk and window bench for our daughters room -Replaced our old single front door and transoms with a beautiful custom oversized double mahogany front door with Flemish glass. They also turned some circa 2000 round structural columns into square columns with trim work that matched the style of our home And lastly, they were CLEAN! This is a HUGE benefit if you are in the market for a builder. Every day his crews tidied up after themselves and never left a mess. We will definitely use Otto for more projects in the future!
