"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.

"I couldn't find a structural engineer to look at my drawings and provide good engineering services until I called Peter. He was willing to look at the project even though there were still questions about the build to be answered."

"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."

"We needed a master bedroom addition and a full remodel of our existing kitchen and two bathrooms. Design 1 Studio handled all of it as one project. The addition was designed to match the existing roofline and exterior perfectly. The interior layouts are functional and beautiful. Our contractor complimented the level of detail in the plans multiple times during the build. We get compliments from every visitor now."

Structural Engineering questions, answered by experts

Watch for quotes that skip a site visit, lack mention of Pasadena-specific code compliance, or ignore the need for permits. Be wary of professionals unfamiliar with local seismic requirements or historic property considerations. Vague communication, missing references, and failure to address foundation assessment or soil analysis are also warning signs that the structural engineering professional may not deliver reliable results for your project.

Helpful?

To ensure a smooth structural engineering project in Pasadena, begin by reviewing local building codes and determining if your property is within a historic district. Schedule a pre-project consultation with city staff, arrange for a geotechnical assessment, and coordinate with utility providers early. Notifying neighbors when required and allowing extra time for the city’s plan review process can also help prevent delays and keep your project on track.

Helpful?

Homeowners in Pasadena often underestimate the impact of local soil conditions, especially when foundation repair or seismic retrofitting is needed. The time required for city permit reviews, utility coordination, and compliance with historic preservation guidelines can also be overlooked. Additionally, seasonal weather and the availability of specialized materials can unexpectedly extend project timelines, making careful planning essential for a successful outcome.

Helpful?

Signs of thorough structural engineering in Pasadena include detailed, stamped structural drawings, comprehensive seismic calculations, and documented approval from city inspections. On-site, expect to see quality materials suitable for the local climate, secure foundation work tailored to Pasadena’s soil, and robust seismic connections. Complete inspection records and clear communication from your structural engineer also indicate a job done to high standards.

Helpful?

Completing structural engineering projects in Pasadena offers immediate benefits like improved safety and smoother permit approvals, especially for earthquake-prone areas. Over time, your home gains increased structural integrity, better protection against wildfires and weather extremes, and enhanced property value. These upgrades also help maintain the historic charm of older homes and reduce the likelihood of costly foundation repairs or structural issues in the future.
