"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

Here is what stood out the most:"

"Working with Jonathan has been a dream. This is the first time I've ever needed and architect and engineering for a home project, and wasn't sure what to expect, but Jonathan was great. He was incredibly patient with the adjustments and revisions that came with the process and pointed out some ideas that I never would have thought of on my own. As a bonus, the plans sailed through the city plan check, getting approved the very next day with no comments. I strongly recommend DesignX."

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

Structural Engineering questions, answered by experts

When hiring in Orange County, prioritize professionals with proven experience in local soil types and seismic retrofitting. Verify their insurance, credentials, and familiarity with regional permitting. Ask for recent project examples in your area and check references. Clear communication and detailed proposals are essential, as is ensuring the pro understands Orange County’s unique building requirements and seasonal construction challenges.

Helpful?

In Orange County, it’s wise to schedule a structural assessment if you notice new wall cracks, sloping floors, or doors that suddenly stick. Homes built before 1980 or located near coastal areas are especially vulnerable to soil movement and seismic activity. After any earthquake, major storm, or before remodeling, arrange an inspection to catch hidden foundation or framing issues early.

Helpful?

In Orange County, you’ll encounter structural engineers for detailed load analysis and seismic retrofits, civil engineers with residential expertise, and contractors focused on foundation repairs or soil stabilization. Some firms offer structural consulting for home additions, while others specialize in hillside or soft-story retrofitting. Choose a professional whose experience matches your project’s needs and local soil conditions.

Helpful?

Combining structural engineering with upgrades like drainage improvements, waterproofing, or seismic retrofitting in Orange County can minimize disruption and streamline the permit process. Coordinating work during the dry season helps avoid weather-related delays. Discuss with your contractor about bundling related projects, as this can reduce the number of inspections and ensure all upgrades meet local building codes efficiently.

Helpful?

In Orange County, structural assessments typically take 4-6 weeks, while seismic retrofit designs or foundation repairs can range from 6 to 20 weeks depending on complexity. Factors like HOA approvals, soil testing, and rainy season delays may extend timelines. Early planning and regular communication with your contractor help keep projects on track and minimize unexpected scheduling setbacks.
