"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!!"

"The project went great. Peter is very professional, super knowledgeable, responsive and timely. The plans were done on time and there were no problems with the city review. They answered the questions the contractor had during the construction. Couldn't be happier with the whole process. I thought it would be more difficult than it was. Thanks to Peter and his team we feel very safe with the new addition. We are planning on putting a second story on our house (when we can afford it) and we will absolutely use Peter.

"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"The architects assisted in getting permits and answered all questions during the course of the construction. Fortunately and thanks to the accurate plans we did not have any corrections related to the plans. I am very happy with Franco Ricalde company and will work with them again. By the way, we received a lot of compliments on the final project which was an ADU in the backyard."

"Mr. Erdelyi helped me legalize a structure in my backyard. The project is still ongoing but Mr Erdelyi was very attentive, invited me to discuss creative solutions and never let me feel that the project is too small. I can appreciate the way Mr. Erdelyi takes care of his customer. I did not introduced my self as such but I am an engineer myself."

Structural Engineering questions, answered by experts

When hiring structural engineering professionals in Los Angeles, prioritize those with proven expertise in earthquake retrofitting and hillside construction. Look for a strong track record navigating local building codes and successful foundation design projects. Ensure they communicate clearly, carry robust insurance, and provide solid references from recent LA-area clients. Avoid firms lacking local experience or those with vague project timelines.

Helpful?

Completing structural engineering projects in Los Angeles offers immediate benefits like meeting strict earthquake retrofitting requirements and improving building safety. Over time, you’ll gain enhanced resilience against seismic events, increased property value in a competitive market, and reduced risk of structural damage. Proactive upgrades also help you avoid future code-driven renovations and support long-term energy efficiency for your property.

Helpful?

Before starting structural engineering work in Los Angeles, review your property’s history for prior earthquake retrofitting or hillside construction. Schedule a soil and foundation assessment, especially if your site is near fault lines or in a liquefaction zone. Secure all required permits early and coordinate with local utility providers. Consulting with neighbors about construction timelines can also help prevent disputes and unexpected project interruptions.

Helpful?

In Los Angeles, small residential structural engineering projects typically take 10–22 weeks, while mid-sized commercial work may require 26–48 weeks. Large-scale builds or major foundation design upgrades can extend to 58–144 weeks. Projects in hillside neighborhoods, historic zones, or those needing extensive seismic upgrades often require additional time due to complex permitting and specialized engineering solutions.

Helpful?

Los Angeles’ dry climate allows for steady construction, but seismic activity and wildfire risk—especially in hillside areas—demand specialized structural engineering approaches. Foundation design must address expansive soils and potential liquefaction zones. Material selection should resist sun exposure and, in coastal neighborhoods, salt air corrosion. Planning around fire season and protecting work sites from rare heavy rains are also essential for successful project completion.
