I begin with this because that structural engineer mentioned he'd had Brian do his own retrofitting and highly recommended him, which was the only endorsement I needed. The scope of the work was soft story retrofit (incl. excavation at the front of the garage to install a Hardy frame, adding in shear walls with bolts, shear wall with URFP ties all along the house's perimeter) as well as adding in anchors (e.g., hand dug piers, rebar, concrete) in the front and back of the house to prevent the house from further sinking. We initially applied for and got into the ESS program, which Brian/Holly guided us through (pulling permits, getting photos, contacting our engineer for letters/responses on ESS program follow-ups). As in the first time and every subsequent time, they were swift and helpful in responding. ESS, if you don't know (like I didn't), goes through FEMA and requires FEMA review and approval of your plans at each step of the way, but the whole program came to a standstill in 2025-26. We had no updates despite us and Brian/Holly repeatedly following up. We gave up on ESS in April and decided to move ahead with the retrofit. Brian was able to work us into his schedule and work began early May and work was completed in just a little over two weeks, a full week faster than I expected. The whole time Brian/Holly kept us apprised of the status, schedule, and inspections; and forwarded us all documentation and pictures as they came up. The crew was efficient and detailed and did thorough clean ups of the worksite after each day. We felt in control and informed the whole time and are confident in the result; I'd hire them again in a heartbeat.

I hired SF Bay Engineering for seismic retrofit plans under the Earthquake Brace and Bolt program…read more I was told architectural drawings were required before they could proceed, so I hired and paid an architect to prepare them. After multiple back and forth and with SF Bay Engineering admitting they aren't familiar with the requirements, they terminated the contract.

I brought the matter to small claims court, and the court ruled that because I retained the plans, reimbursement was not warranted.

I initially signed a contract with Prostruct, but after Irvin reviewed my photos, he demonstrated a level of integrity that is rare to find. Instead of taking the job, he honestly informed me that my specific issues fell outside their scope. He took the time to explain what I was seeing, referred me to a geotechnical engineer who could actually solve the problem, and issued me a full refund. I greatly appreciated his transparency and professional guidance. I highly recommend Prostruct Engineering to anyone looking for an honest assessment--they clearly prioritize the customer's needs over their own bottom line.

From the very beginning, we were impressed with Senthil, Ryan and other members of Zenith team's level of professionalism, prompt response, architectural knowledge and effective communication.This level of service was seamless through our entire engagement with Zenith Engineers Inc., from obtaining the building permit to successfully passing all necessary inspections by the SF Building Department. No one questions their architectural work because they are so good at what they do. We had some initial concerns after reading negative reviews, but as the project progressed, it became clear that those comments were based on personal grievances, rather than valid concerns. The team at Zenith Engineers Inc. has a high level of professional ethics and integrity. Zenith's management team had explained to us early on in the project, the strict adherence to code and compliance was paramount throughout the project. If Zenith compromises to satisfy unsatisfied clients, the building will end up being non-compliant and more importantly unsafe. We truly appreciate Zenith's commitment to quality and integrity, even if it means earning a few negative reviews along the way, which seem rather unfair to them as they are simply doing their job. I am extremely satisfied with the professional and excellent work the team at Zenith Engineers Inc. provided us and will hire them in a heartbeat for all our future structural and/or seismic engineering needs. Thank you Senthil, Ryan and the Zenith engineering team for your professionalism and support. It was our best decision to work with you and experience such high standard of professionalism, work ethic, and integrity.

After having used Zenith for multiple projects in the last few years, looks like it's finally time…read moreto look for someone else for the next one. We started using Zenith because of its responsiveness and effectiveness when it came to structural design. With them as part of our team, we were able to keep up with the City submittal and response timelines we had set. Fast forward to today, and we can't get a hold of anyone. When we do, it's always an excuse for why they didn't respond, without a resolution. We sent them the last City comments 30 days ago and have yet to get anything viable to re-submit back to the city. Given that this is a 30-unit hotel project, going with a different firm now will mean a complete re-design of the project; an absolutely painful exercise that will set us back months. Zenith knows that. So it's absolutely shameful for them to act in a way that would even suggest that our only choice is to get the entire project re-designed by another firm just to have it keep moving forward. So much for "we respond to emails within 30 minutes and always answer phone calls" as outlined on one of their online profile. Knowing how we were treated on this round of City comments and the fact that the entire company seems complacent about what they try to embody in their rhetoric, I would stay away for any future project.
