"We are incredibly pleased with the ADU that United Services built at our home. Glenn and his entire team were professional and responsive from the planning stages through to the finished project. They coordinated the architectural design, building permits, and inspections, ensuring that everything proceeded smoothly. They built the ADU to perfectly match our house, using complementary exterior materials, roofing, flooring, and paint color palettes. The commitment and expertise that each team member and subcontractor applied to their work was greatly appreciated. We highly recommend United Services and would certainly hire them again for any future building projects. "

Marksman Builders Inc has been building in Placer, Nevada, and El Dorado counties since 1983. We are a fully licensed and insured contracting business. Our specialty is residential construction - custom homes and remodels. We work with local designers to help clients achieve home plans that meet their needs and expectations. We also are glad to give a price quotation on existing plans. Having over 40 years of building experience in the Gold Country we realize the special conditions and challenges of construction in the area. We make a commitment to staying up to date on code changes and new technologies within the building industry. Please feel free to contact us with any questions you may have.

"Over the years I have worked with several contractors/builders and Marksman Builders has been the best. They delivered on every aspect of our complete older home remodel. Last summer we started with just ideas on a piece of paper and Emma and her team worked with the designer, engineer to retain the charm of our older home and give it an open modern look. The entire process from obtaining building permits to the final details were professionally completed within the estimated timeline and budget. As the project took shape we had several change orders that were seamlessly integrated into project. Friends, family, and other building professionals have commented on how “awesome” our new house looks. Marksman Builders is now building a very custom engineered carport and garage for us with the same professionalism and attention to every detail. I was not sure it could even be built given the terrain and larger granite boulders. They simply incorporated the boulders in the build."

"Michael and team did such an amazing job on our bathroom remodel. They took our tiny, dysfunctional bathroom and turned it into a true master bathroom oasis in a short amount of time during the holiday season. When they had the space down to the studs, Michael sat down with us and discussed in detail the best possible use of the space and we couldn’t be happier with our final decision after going through the options. Michael was great at communicating and we still stay in touch to this day, which we truly appreciate. Great team who does great work and I will absolutely be giving Waters Construction a call for any and all future home renovations. I’ll let the pictures do the rest of the talking. "

FAQs for addition to existing structure building service projects in Grass Valley, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
