"We hired Joe Lutz Construction to build a new two car garage from plans provided by a local architect. The build site was a challenging sloped lot and Joe provided photos and customer contacts of similar jobs he had done, demonstrating his skill and competence which gave us confidence. Joe presented a contract that was clear and professional listing materials and methods of construction with a payment timeline related to the completion of various stages of the build. He handled all of the permit inspections and kept the project on track. The quality of the work was excellent, and Joe's communication skills kept us informed and updated on all aspects of the project. We are very satisfied with the work Joe and his team did and highly recommend him for your next construction project."

"I recently had the pleasure of working with Genjazz Building and Electric Company for the renovation of my bathrooms, and I couldn't be happier with the results! From start to finish, the team displayed exceptional professionalism, skill, and attention to detail. Initially, I was impressed by their comprehensive consultation process. They took the time to understand my vision, offer valuable suggestions, and provide a clear timeline and budget. The design they presented was creative yet practical, perfectly aligning with my needs and style preferences. Throughout the renovation, the crew was punctual, respectful, and maintained a clean work environment. They tackled unexpected challenges with ease and kept me informed every step of the way. Their craftsmanship is top-notch; the tile work, cabinetry, and finishing touches were executed flawlessly. Not only did they meet all deadlines, but they also delivered high-quality work that has completely transformed my bathrooms into beautiful, functional spaces.

Addition to existing structure building services FAQs
How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.
Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
