Residential Structural Engineering
Residential structural engineering in Los Angeles for ADUs, additions, remodels, new homes, and hillside projects. Professional Engineers provide permit-ready plans and calculations
Residential Structural Engineering in Los Angeles
Los Angeles residential projects move fast, and they often involve existing conditions, seismic design requirements, and tight site constraints. We provide residential structural engineering focused on clear load paths, practical details, and documentation that supports permitting and construction. In Los Angeles, these projects often involve tight urban sites, hillside conditions, or older framing where consideration of the LA Dept. of Building and Safety (LADBS)permitting and seismic detailsplaysa key role.
Our work is led by Professional Engineers (PEs). We coordinate with homeowners, architects, and contractors to deliver structural plans and calculations that are code-aligned and buildable.
Who This Service Help
- Homeowners planning an ADU, remodel, or addition
- Architects and designers needing structural plans and calculations for permits
- Contractors looking for responsive engineering support during construction
- Property owners evaluating structural changes to an existing home
Comprehensive Structural Engineering Services
Discover a comprehensive suite of structural engineering services tailored to the diverse demands of Los Angeles. Our capabilities include structural design, seismic and earthquake engineering, foundation analysis, building assessments, and retrofit solutions—each delivered with technical rigor, creativity, and a commitment to long-term performance.
Scope and Capabilities
- New custom homes: Full structural engineering for new homes using wood, steel, and concrete systems. We coordinate with architectural intent while maintaining straightforward load paths and robust seismic detailing.
- Home additions and expansions: Structural support for one-story and two-story additions, including new beams, posts,footings, and integration with existing framing. We prioritize constructability and predictable inspection outcomes
- ADUs and garage conversions: Structural design for new ADUs and conversions, including gravity framing, lateral systems, foundation sizing,and connection detailing appropriate for the project and jurisdiction.
- Load-bearing wall modifications: Design for new openings, beam replacement, and reconfigured layouts. We evaluate loads, select appropriate members, and provide details that contractorscan build cleanly.
- Foundations and hillside conditions: Foundation design and coordination with geotechnical recommendations when available. For hillside sites, we help align structural systems with grading constraints and access limitations. On hillside propertiescommon in neighborhoods like Pacific Palisades, Hollywood Hills, and parts of Bel Air, we align structural systems with grading constraints and limited access.
In some cases, a structural assessment of the existing home may be recommended before final design decisions are made.Where damage or deterioration is present, we can also develop targeted structural repairsthat restore capacity and improve long-term performance
Deliverables
- Structural plans, details, and notes prepared for permitting and construction
- Structural calculations tailored to the jurisdiction and scope
- Coordination support with the architect and contractor during plan check as needed
- Construction support for field conditions, RFIs, and clarifications when requested

Permit-ready documentation
Construction support
- Permit-ready structural plans and structural calculations sized for the project and jurisdiction.
- Coordination with architectural layouts, existing framing, and foundation constraints.
- Clear detailing that supports efficient construction and predictable inspections.
- Construction-phase clarification and field-condition support when requested
Additional Residential Considerations
- Projects in Los Angeles often require coordination with seismic design requirements, variable soil conditions, and constrained urban sites.
- Many Los Angeles homes also benefit from seismic retrofitting for residential buildings to improve earthquake performance and safety.
- Design approaches are tailored to existing construction soadditions, remodels, and structural modifications integrate cleanly with the original structure.
