Structural Engineering Services We Provide Across Orange County
Handasa Inc. provides a full range of structural engineering services to Orange County clients, covering both new construction and existing structures:
New Commercial Structural Engineering
Our Orange County structural engineers design all types of commercial buildings, including offices, retail centers, warehouses, hotels, motels, podium buildings, and mixed-use developments. We collaborate with architects and designers from project inception to ensure structural integrity, code compliance, and cost-effective design from foundation to roof. We work with wood, steel, concrete, and masonry block structures.
Residential Structural Engineering
Handasa Inc. provides structural engineering calculations and design for new residential developments, including custom homes, tract housing, apartment buildings, and ADUs throughout Orange County. Our work meets California Building Code requirements and is designed to pass plan check with minimal revisions.
Tenant Improvements (TI)
Commercial tenant improvement projects, such as office reconfigurations, warehouse expansions, or structural additions to retail spaces, require a licensed engineer specializing structural engineering who understands both project demands and commercial timelines. Our Orange County engineers deliver TI solutions that keep projects on schedule and within budget.
Residential Remodels and Additions
Adding a room, removing a load-bearing wall, or reconfiguring your home’s structure requires careful analysis of your existing building. Handasa Inc. provides the structural engineering services Orange County homeowners need to proceed with confidence, ensuring new and existing elements work together structurally and comply with local building codes.
Apartment Complex Structural Engineering
Multifamily developments and apartment complexes have structural demands that single-family projects do not. From podium-style construction over parking structures to multi-story wood-frame apartment buildings, our Orange County engineers bring the expertise and precision these complex multifamily projects require.
Retaining Walls
Sloped lots, underground parking structures, and multi-tier developments across Orange County often require retaining wall engineering. Handasa Inc. designs retaining walls that comply with the Building Code and align with the geotechnical parameters in your site’s soil report, ensuring stability and long-term performance.
Why Orange County Clients Choose Handasa Inc.
25+ Years of Structural Engineering Experience
Founded in 1999, Handasa Inc. has more than 25 years of experience in structural and civil engineering in Southern California. Our team has worked on all types and sizes of projects throughout Orange County, from simple residential additions to complex commercial developments. We have built a track record that architects, contractors, developers, and homeowners trust.
Deep Knowledge of California Seismic Requirements
Orange County is in a seismically active area. Every structural design by Handasa Inc. considers earthquake loading, lateral force resistance, and the seismic details required by the California Building Code. We design structures that meet CBC requirements for seismic zones, giving clients confidence that their building is safe and built to perform.
Code-Compliant Work That Passes Plan Check
Architects and contractors across Orange County often tell us that our work passes plan check on the first submission. Accurate calculations, complete documentation, and careful attention to Building Code compliance help reduce delays and keep projects on schedule. That is why clients return to Handasa Inc. for project after project.
Personal Service from an Owner-Led Firm
At Handasa Inc., clients work directly with our lead engineer throughout the project, not with a rotating team of junior staff. This continuity means your engineer knows your project’s history, responds quickly to questions and changes, and stays accountable from start to finish. It is the kind of service that large Orange County engineering companies cannot match.
Competitive Pricing and Fast Turnaround
Structural engineering should not slow down your project. Handasa Inc. offers competitive pricing and quick turnaround times that fit the schedules of architects, contractors, and developers working with tight deadlines throughout Orange County.

Structural Engineering in Southern California — Why the Right Engineer Matters
California’s building codes are some of the most demanding in the country, and for good reason. The state’s seismic activity, wind-loading requirements, soil differences across Orange County, and strict plan-check processes from city building departments make structural engineering here a specialized field.
Structural miscalculations or incomplete documentation do not just cause plan check delays. They can also lead to costly redesigns, construction stoppages, and, in the worst cases, structural failure. Choosing an experienced, licensed engineer in Orange County who knows the California Building Code and local plan check requirements is one of the most important decisions you can make for your project.
Handasa Inc. has worked with building departments in cities across Orange County for over 25 years. We know what each jurisdiction expects, how to prepare documentation that meets plan check requirements, and how to resolve technical questions efficiently. This helps keep your project moving from approval through construction.
