Why ADUs Make Sense in San Juan Capistrano

Large and semi-rural lots create room for detached ADUs. Many SJC neighborhoods have deep backyards, side yards, or paddock areas that can support a detached casita, guest house or multi-gen unit when designed to meet current code.
Equestrian character pairs well with multi-gen living. Larger homes and paddock-style layouts often make it easier to integrate an ADU for extended family, caretakers, or tenants while keeping privacy and open space.
Updated ADU ordinance aligns with state law. The City’s ADU and JADU regulations have been amended and reviewed by the California Department of Housing and Community Development (HCD) to stay consistent with state-level requirements.
Historic core and design review add uniqueness. In and around the Historic Town Center, ADUs may be shaped by architectural guidelines and context-sensitive design, which can enhance long-term appeal when done correctly.
