At LEVEL, we are committed to common sense, real-world solutions. We pioneered LEVEL because, after years spent exploring all disciplines of civil and structural engineering in the building industry, we continually encountered the missing fundamentals in our own trade. These lost elements of service culture & exceptional business practice inevitably cost owners & entities untold stress and frustration; contractors lost time & money, realtors & lenders were left unable to satisfy their client's needs. We concluded that our capacity for A&E services could function at a higher level, thus, LEVEL Engineering & Inspections was founded. We serve your interests & provide knowledgeable, expert design, inspections, analysis, forensics, recommendations, and reporting. Whether your need is for permitting, forensics; new, remodel, or repair engineering designs; foundation problems; civil or architecture - let us help you navigate your Civil, Commercial, Residential Structural Engineering needs.

"Seemed knowledgeable, helpful advice. My only problem was that it seems impossible to get an answer when trying to reach them for a follow up question."

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?

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.

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?

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.
