This Huntington Beach project converted existing structure into a complete 432 sq ft accessory dwelling unit with one bedroom, one bathroom, and a full kitchen.
Conversions are the most cost-effective path to a legal ADU because the shell, slab, and utility connections already exist — the budget goes into livability and finishes rather than foundation and framing.
The finished unit is fully self-contained with its own entrance, making it ideal for rental income or housing family in one of Orange County's most desirable coastal cities.
Vision ADU handled the conversion from permits through final inspection.
