Lee & Lee Structural Engineering Inc.

Lee & Lee Structural Engineering Inc. is a California-based structural engineering consulting firm providing structural design, engineering analysis, and construction documentation for a wide range of building projects. Established in 1989, the company serves architects, contractors, developers, and other project stakeholders seeking practical, code-conscious structural engineering solutions. Based in Los Angeles, the firm works on residential, commercial, industrial, public, and adaptive reuse developments across California and beyond.

With decades of experience in structural consulting, Lee & Lee Structural Engineering Inc. focuses on creating building systems that balance structural safety, practical construction requirements, project objectives, and cost efficiency. Its work covers different building materials and structural systems, helping project teams address the engineering needs of new construction, renovations, and complex developments.

Structural Engineering and Building Design

Structural engineering is an essential part of successful building development. Structural systems must be designed to support applicable loads, work with the architectural layout, and satisfy relevant building codes and project requirements. Lee & Lee Structural Engineering Inc. provides structural engineering and design services for projects that require careful analysis, coordinated documentation, and practical engineering decisions.

The company works with structural systems involving wood, structural steel, concrete, masonry, light-gauge framing, concrete masonry units (CMU), tilt-up construction, and hybrid systems. Selecting and coordinating the appropriate structural system depends on factors such as the building configuration, intended use, design requirements, and construction conditions.

By coordinating structural considerations with the wider project team, the firm supports the development of structural solutions intended to be safe, functional, and constructible.

Residential and Multifamily Structural Engineering

Residential development can involve single-use buildings, multifamily housing, apartment complexes, and mixed-use properties. These projects may require structural coordination across residential spaces, parking areas, commercial units, and shared building components.

Lee & Lee Structural Engineering Inc. has experience with multi-unit housing and residential developments. Its published project portfolio includes the La Puente Apartments, a 30-unit mixed-use development with integrated parking and retail spaces. The project demonstrates the coordination required when residential occupancy is combined with commercial functions within one development.

The firm also contributed to the Lankershim Apartments project in Los Angeles. This development features wood-framed residential construction above a retail and parking podium, illustrating the use of different structural systems within a single building.

For developers and design teams, this type of project experience provides relevant context when evaluating a structural engineering consultant for residential or mixed-use construction.

Commercial, Industrial, and Public Buildings

Commercial and industrial buildings can have different structural requirements depending on their occupancy, layout, building materials, equipment needs, and intended operations. Lee & Lee Structural Engineering Inc. reports experience across commercial buildings, factories, hotels, religious facilities, public buildings, and other building types.

The firm’s structural consulting approach considers the specific requirements of each project rather than treating every building as the same design challenge. Structural materials and systems can be selected and coordinated according to the building’s design, applicable codes, and construction objectives.

For architects, contractors, and developers, collaboration with a structural engineering consultant can help align structural documentation with architectural design and project delivery requirements. Early coordination is particularly useful when a project includes mixed occupancies, multiple structural materials, or complex building configurations.

Remodels, Seismic Retrofits, and Adaptive Reuse

Existing buildings often require engineering solutions when they are renovated, modified, strengthened, or adapted for new uses. Structural changes may affect load paths, framing systems, connections, or the way an existing building responds to applicable forces.

Lee & Lee Structural Engineering Inc. identifies remodels, seismic retrofits, and adaptive reuse among its service areas. These services support projects in which an existing structure must be evaluated and coordinated with a proposed renovation or change in use.

Adaptive reuse can give an existing building a new purpose while retaining parts of its original structure. Seismic retrofit projects may involve strengthening or modifying structural elements to address defined performance and code requirements. The appropriate engineering scope depends on the existing building, available documentation, observed conditions, and proposed work.

Project owners and design professionals should discuss the building’s existing condition and intended changes with the engineering team before establishing the scope of structural services.

Structural Calculations and Permit-Ready Documentation

Accurate structural calculations and coordinated drawings are important components of the building permit and construction process. Lee & Lee Structural Engineering Inc. states that it prepares structural calculation packages and construction drawings intended for submission, review, and approval.

Well-organized engineering documentation helps communicate the design intent to architects, contractors, plan reviewers, and other project participants. The exact documents and level of detail required depend on the project scope, the applicable jurisdiction, and the reviewing authority.

The firm’s published materials describe the use of engineering and drafting tools including ETABS, SAFE, SAP2000, and AutoCAD. These tools support structural analysis, design development, and the preparation of technical drawings and documentation.

Clients should confirm the required deliverables, review stages, professional approvals, and permitting responsibilities with the firm for each individual project.

A Collaborative Approach to Structural Consulting

Lee & Lee Structural Engineering Inc. emphasizes personalized service, clear communication, and practical engineering solutions. Its company information describes collaboration with architects, contractors, and developers, alongside direct oversight from a licensed structural engineer.

Successful building projects depend on coordination between structural engineering, architecture, construction planning, and applicable regulatory requirements. A clear project scope and timely communication can help the wider team identify design constraints and address technical questions as the work progresses.

Whether a project involves new construction, a multifamily development, a commercial building, or the rehabilitation of an existing structure, the engineering requirements should be established around the building’s specific needs and objectives.
