STRUCTURAL ENGINEERING FOR REMODELS & ADDITIONS

Structural Design for Existing Homes

Altering an existing structure changes how loads travel through the home. Proper evaluation and engineering ensures new loads are safely supported, excessive deflection is avoided, and seismic performance is maintained. Our structural plans are prepared in accordance with current California Building Code requirements for residential construction.

Typical Structural Services

Key Structural Components

Beams & Headers

Structural members installed when load-bearing walls are removed or openings are enlarged.

• Engineered wood (LVL/PSL) or structural steel beams
• Sized for span, tributary loads, and deflection limits
• Posts and bearing supports to transfer loads vertically
• Connection detailing for safe load transfer

Foundations & Footings

New or upgraded foundations safely support added loads from remodels and additions.

• Slab-on-grade systems and reinforced concrete footings
• Anchor bolts and hold-down hardware
• Reinforcing steel for strength and crack control
• Supplemental footings or underpinning where required

Framing & Load Paths

Proper framing ensures gravity and lateral forces travel continuously to the foundation.

• Floor and roof joist evaluation and reinforcement
• Beams, posts, and bearing walls aligned for load transfer
• Blocking and collectors for force continuity
• Coordination with existing structure

Lateral & Seismic Systems

Structural elements that maintain stability during wind and earthquake forces.

• Plywood shear walls and braced wall lines
• Hold-down devices and metal hardware
• Straps, ties, and anchor connections
• Continuous load path from roof to foundation
