Home Additions

When your family outgrows your current home, a well-designed addition is often more cost-effective than moving — and Ultimate Riverside Contractors has the project management experience to build it correctly from the ground up. We handle room additions, second-story expansions, garage conversions to living space, and covered patio enclosures throughout Riverside and the surrounding Inland Empire communities.

Every home addition project begins with a detailed assessment of your existing foundation, framing, and utility systems to ensure the new structure integrates properly without compromising the integrity of the original home. We coordinate architectural drawings when required, submit for City of Riverside building permits, and schedule all structural, framing, electrical, plumbing, and final inspections through the appropriate city departments.

Our crews frame, insulate, drywall, and finish every addition to match the look and feel of your existing home — including matching exterior stucco textures, rooflines, window styles, and interior trim profiles. From a 200-square-foot bedroom addition to a 1,000-square-foot family room and attached garage, we deliver projects that look like they were always part of the original design.
