I felt it was important to share our experience with JZ structural as I ultimately went with them…read moregiven their high Yelp reviews. However, my experience was negative to say the least. Ellen was responsive initially, but this was only until they received payment. After this, trying to get a response was like getting blood from a stone: close to impossible. My architect had asked Julian, the engineer, if he could draw a rough mock up before he put together a full set of plans (to which he agreed). We never got this, despite checking in multiple times, and instead, it was only right upon the 'deadline' we had provided for the project that we received a full final set of plans. This was disappointing. The plans themselves were riddled with errors: it seemed like a lot of copy / paste work rather than careful attention to detail. The wrong county was listed, and certain structural details were copy pasted from the wrong city, which my architect had to point out. We had around 30 local contractors look at the plans, as well as two peer reviews of the plans from other licensed structural engineers, and the feedback was that it had been over-designed (consistent with one of the other yelp reviews). After multiple emails attempting to get Julian (the engineer) on a call, he was incredibly defensive, and rude. It was at this point, I was appalled that he would speak to a client like this, so decided to cut ties with this company and use another structural engineer instead. If you are in absolutely no rush, and have no concerns about over-design: perhaps this company will work for you. But for our residential project, this was one of the worst experiences I have had with a "professional" service, and I want to warn others.

They also diligently worked with the city, project manager, and other contractors to get the job done. Ellen and Julian also provided a very personal touch with guidance in hiring contractors, materials to use for the project, and design.

Would highly recommend getting in touch with them if you need help with building and large renovation projects.

Their expertise literally saved our build from a very poor framing contractor. The contractor caused massive delays due to non-existent planning, mismanaged materials, and repeatedly misinterpretation of the structural stamped drawings, including framing ceiling joists improperly and installation detail errors. Fortunately, the owner, Francisco Garcia, stepped in with efficient practical solutions for every single error while maintaining code compliance and structural integrity. Francisco was incredibly patient, performing comprehensive hold point inspections, clearly explaining details to help contractor's rework and omissions. He accommodated last minute inspection requests time and time again. Now that framing is officially signed off by the city, we have absolute peace of mind. Francisco and his team are the communicative, professional experts you want in your corner, whether for a remodel or new construction. FJ Engineering will contribute to the success of your project through the value they bring from initial development of structural plan drawings and his diligent oversight through final sign-off.
