Accessory Dwelling Units require safe, efficient structural systems that meet modern building and seismic code requirements. We provide complete structural design services for new detached units, attached additions, and garage conversions—delivering clear, permit-ready plans that ensure strength, stability, and long-term performance.

ADUs must safely transfer gravity and lateral loads from the roof and floors down to the foundation. Proper detailing of foundations, framing, and connections creates a continuous load path that allows the structure to perform reliably during everyday use and seismic events.
Our structural plans are prepared in accordance with current California Building Code requirements and local jurisdiction standards, helping streamline the permitting process while maintaining safety and efficiency.
Foundations support the entire structure and distribute loads into the soil. We design slabs, footings, stem walls, and anchorage systems based on site conditions, building loads, and seismic demands.
Efficient framing layouts provide strength while keeping construction practical and economical. Structural members are sized to safely resist gravity and lateral loads.
Shear walls and hardware resist wind and earthquake forces, preventing excessive movement or damage during seismic events.
Existing structures often require evaluation and strengthening to meet current standards. We design upgrades to foundations, walls, and framing to safely support the new use and layout.
