Lee & Lee Structural Engineering Inc. is a Los Angeles–based structural engineering consulting firm established in 1989. From humble beginnings with just two engineers and a drafter, we have grown into a multidisciplinary team trusted by architects, contractors, and developers across California and beyond.

With over three decades of industry experience, we’ve successfully delivered thousands of projects ranging from high-rise commercial towers, hotels, and factories to community churches, multi-unit housing, and adaptive reuse buildings. Our broad portfolio reflects our flexibility across materials, including wood, concrete, structural steel, light-gauge framing, CMU, tilt-up, and hybrid systems.

At the heart of our work is a commitment to safety, practicality, and code compliance. We blend solid engineering principles with state-of-the-art design tools like ETABS, SAP2000, SAFE, and AutoCAD to ensure constructible, economical, and performance driven solutions.

Every project we take on receives direct oversight from a licensed structural engineer. We work closely with our clients to understand their goals, budgets, and constraints and to deliver customized solutions that last.

Whether your project is a ground up development or a seismic retrofit of a historic structure, Lee & Lee is here to guide you from concept to completion with precision and care.
