I scheduled a consultation with Eugene from STEN Engineering to discuss two very different…read morestructural issues at my house, and I was extremely impressed. The first was figuring out how to realign a very complicated roofline so that rainwater would channel properly. The house has been built and added onto in stages over roughly 100 years, so every addition and alteration made the roofline more complicated and less cohesive. I had literally spent hours sitting on the roof trying to figure out a workable solution. Eugene looked at the situation, thought it through for about 10 minutes, and sketched out an option that simply would never have occurred to me. It was practical, elegant, and made immediate sense. The consultation was some of the best $400 I've spent. The second issue was understanding how well the house is braced for earthquakes and how the existing foundation works structurally. Again, Eugene combined a strong engineering mind with real-world practical experience and explained everything in a way that I could actually understand. I almost never take the time to write reviews, but I was impressed enough that here I am writing one. Eugene is smart, thoughtful, practical, and very good at explaining complicated structural issues in plain English. I would absolutely call him again.

So glad I found LA Structural! They called me right back, scheduled a time for the next weekday, and Brandon showed up right on time. He took a look at my concerns & got under the house (on a 99 degree afternoon!). Brandon reassured me that there are no structural concerns, then took the time to explain how the supports under the house work, and why I might notice uneven places in the flooring. He did not try to sell me on anything, and did not charge me for the consultation. He gave me a ballpark estimate if I ever decide to do optional earthquake bracing, in a no-pressure manner; he was very clear that it's not a necessity. I'm so grateful for local Burbank businesses that offer their expertise to our community. Thank you!

LICENSE SUSPENDED: Avoid This Contractor: Failed to Comply with CSLB Arbitration Award…read more I am updating this review to warn other homeowners to check the California Contractors State License Board (CSLB) records before hiring LA Structural. As of March 2026, their license has been officially suspended due to their failure to comply with a legally binding arbitration award. On October 22, 2024, LA Structural requested and collected full payment for the second contract (permit acquisition for all work listed in the first contract) before any permit-related work began. Note: This is a violation. Despite full payment on November 26, 2024, none of the required permit finalizations occurred as promised, and the contractor stopped all permit-related work. Required tasks--such as coordinating inspections, correcting the soil compaction report rejected by LADBS, and managing final permit approvals--were not performed by LA Structural and were left entirely to me. I spent the following five months working directly with LADBS and city inspectors to complete these tasks. During those five months, I identified two defective areas of work. First, the soil compaction report was rejected due to LA Structural's circumvention of requirements. LA Structural hired a deputy instead of a third-party geotechnical engineer, bypassing the grading inspector's requirement and misleading me as the client after charging an additional fee for this engineer and report in November 2024. Consequently, in February 2025, Inspector Bonvouloir officially rejected the report. Later, Clark Inspections--the subcontractor hired by LA Structural--emailed me stating that LA Structural planned to use their in-house engineer to revise the soil compaction report, again attempting to bypass the requirement. I ultimately had to redo the soil compaction report through a licensed geotechnical engineer and resubmit it, after which it passed the city's review. The second defective work involved the drainage pipe and was documented in the CSLB investigation report. After 13 months of CSLB mediation, investigation, and site inspection, a mandatory arbitration hearing took place on January 22, 2026. The arbitrator ruled in my favor and ordered payment within 30 days. LA Structural failed to comply, resulting in their current license suspension. Notably, prior to the issuance of the stipulated arbitration award letter, the contractor repeatedly attempted to have me sign his own private settlement agreement--non-CSLB documents with terms that went beyond what had been agreed upon at the hearing. Don't sign it! I later learned that this is a common tactic contractors use to remove CSLB from the matter. Per CSLB instruction, I filed a claim with their bond company, Jet Insurance, to recover the awarded payment. Despite their written commitment on February 11, 2026, to issue payment if the contractor failed to meet the CSLB deadline, Jet Insurance instead extended the deadline to March 27, 2026, stating that "the contractor intends to make payment by this week." LA Structural failed to meet this extended deadline as well. On March 30, 2026, I received an email from Jet Insurance stating, "Attached is the Final Release and Assignment of Claim agreement, relating to the claim...In order to issue payment for this claim, Jet Insurance Company requires the attached agreement to be reviewed, physically signed and all pages returned." It has taken 16 months to recover my funds for their abandoned and defective work since their collection of full payment. Based on my understanding, when a bond company pays out a claim, the contractor's license remains suspended until specific legal and financial requirements are met for reinstatement.

When we moved to Oxnard, California two years ago, we did not realize that the parking rules would…read morebe so restrictive. It did not take long for the HOA to make it clear that we had a problem. After a few letters from the HOA delineating the parking rules for both the driveway and the street we searched for a contractor who could remodel the garage to accommodate our 24-foot Sprinter Van. After researching a few companies in the area, we decided on Atlas Builders and Development, Inc. and we were happy to sign a contract with Jacob Lankri, the owner. The first step was to decide on the basic design package. Once that was settled, we submitted the engineered plans to our HOA. After many months of wrangling with the HOA, Gilah Lankri, the project engineer, was able to produce engineered drawings that met the HOA's aesthetics and expectations. Jacob and Gilah submitted the plans to the city of Oxnard. Unfortunately, it took the city of Oxnard a frustrating 10 months to review and approve the plans. All the while, Atlas Builders and Development, Inc. stayed with us determined to get approval. Once we got approval to begin construction in December 2024, the demolition of the old garage was accomplished quite quickly. Even though we hit a snag regarding the Southern California Gas Company line, we eventually got approval to relocate and replace the line which delayed the project 5 weeks. Finally in March 2025 construction of the new Garage began in earnest. Jacob's team, led by an amazing foreman, Edgar, constructed a new elevated ceiling in the garage with new rafters and support beams as well as new tiled roof. The inside of the garage was completely refinished with drywall, texturing and fresh paint. New and improved lighting was installed in the garage along with assorted electrical outlets. The finishing touches included a new door to the backyard, matching the epoxy surfacing on the garage floor and patching preexisting holes in the walls. Outside, new stucco and siding had to be applied as well as painted. The disconnected solar panels and rain gutters were expertly reinstalled. In addition, an area of the driveway had to have pavers reinstalled looking better than before. I addition to the garage remodel project, Atlas Builders and Development, Inc. procured and installed a new sliding glass door complete with a doggy door for access to the back patio. They also removed a set of windows in the dining room and then procured and installed a beautiful set of French doors. Finally, Atlas Builders and Development, Inc. removed an old single front door and expertly installed a beautiful mahogany double front door. All the finishing details were expertly accomplished.
