An ADU contractor and an ADU builder often overlap in their roles, but there are slight distinctions. An ADU contractor refers to a professional who oversees the entire construction process, ensuring that everything, from site preparation to final inspections, follows legal guidelines and quality standards. They work closely with homeowners to ensure compliance with zoning codes, permits, and other construction regulations. An ADU builder, on the other hand, is typically more involved in the hands-on process of physically constructing the ADU or accessory dwelling unit. This includes framing, roofing, and installing utilities systems. Some companies or professionals handle both roles, offering turnkey solutions where they manage the entire ADU project from start to finish. In LA County, where ADUs are popular for expanding living spaces, many ADU contractors also double as ADU builders, taking on responsibilities from design to construction. Whether you’re converting a garage into an ADU or building a tiny house or granny flat from scratch, hiring a professional who is both a contractor and builder ensures a smooth process. This dual expertise helps you navigate zoning regulations, plan efficient use of sqft, and add value to your property
