About This Service
Room Addition Services
A room addition expands your home's footprint by adding new square footage - a bedroom, bathroom, family room, home office, or any other living space. Unlike an ADU (which is a separate dwelling unit with its own kitchen), a room addition becomes part of your existing home and is ideal for homeowners who need more space for their current household.
CCS Inc. designs and builds room additions that blend seamlessly with your existing architecture. Our team handles every phase: design, structural engineering, permitting, foundation, framing, roofing, electrical, plumbing, HVAC, insulation, drywall, flooring, and finish work. We ensure that the addition matches your home's roofline, siding, and style so it looks like it was always part of the original structure.
Room additions in Los Angeles require building permits and must comply with zoning setbacks, lot coverage limits, and building codes. CCS navigates these requirements daily and knows how to maximize your addition's size within the rules. We also help homeowners understand the difference between a room addition and an ADU - in many cases, converting a planned room addition into an ADU (by adding a kitchen and separate entrance) can significantly increase your property's value and income potential.
