The primary difference between an addition and a Jadu lies in their construction and legal status. An addition is a permanent structural expansion of your home, built with foundations, a roof, and full integration with the existing structure. It requires proper permits, follows building codes, and adds livable square footage that is recorded with the county. A Jadu, by contrast, is an informal, often unpermitted conversion of existing space, such as a garage or basement, into a living area. It typically lacks proper permits and may not meet safety or zoning regulations. While a Jadu can provide extra space, it can create legal and insurance issues. For a compliant and safe project in San Diego, Chula Vista, National City, La Mesa and Spring Valley CA, Golden Shore Design and Build recommends always pursuing a permitted addition to ensure quality and peace of mind.
