Room Addition / ADU (JADU) Construction in National City

Why Room Additions & ADUs Matter

Room additions and ADUs (including JADUs) offer practical space solutions while increasing property value. You can create guest rooms, rental units, home offices, and extra living areas without the need to move. With proper planning and professional design, the entire project becomes smooth, organized, and stress-free.
National City features diverse home styles, compact neighborhoods, and multi-family possibilities—making it an ideal location for ADUs and room expansions.
