Commercial Building Structural Permits in Long Beach: Complete 2026 Guide

Navigating commercial building structural permits in Long Beach requires understanding both California Building Code requirements and the specific procedures of the Long Beach Development Services Department. Our licensed Professional Engineers with over 20 years of experience specialize in preparing PE-stamped structural plans that meet Long Beach's stringent requirements, helping commercial property owners, developers, and contractors achieve permit approval efficiently.

As Los Angeles County's second-largest city and home to one of the nation's busiest ports, Long Beach has a diverse commercial building stock ranging from historic downtown structures to modern port-adjacent industrial facilities. Understanding the structural permit process is essential for any commercial construction, renovation, or tenant improvement project in this dynamic coastal city.

Commercial building structural permits are official authorizations from the Long Beach Development Services Department that allow construction work involving structural modifications to commercial properties. These permits ensure that all structural work complies with California Building Code requirements, protecting building occupants and the public from unsafe construction.

In Long Beach, structural permits are required for any work that affects the load-bearing capacity, lateral resistance, or structural integrity of a commercial building. This includes new construction, additions, tenant improvements involving structural modifications, seismic retrofits, and foundation repairs. The permit process involves plan submittal, plan check review, permit issuance, and inspections during construction.

Long Beach's location along the coast and within a seismically active region means structural permits receive particular scrutiny for compliance with seismic design requirements and coastal construction standards. Commercial buildings must demonstrate adequate resistance to earthquake forces and, in some areas, consideration of coastal flooding and sea-level rise impacts.

Understanding which projects require structural permits helps commercial property owners plan projects appropriately and avoid costly delays from unpermitted work.

All new commercial buildings in Long Beach require structural permits as part of the overall building permit package. Structural plans must be prepared by a California-licensed Professional Engineer and demonstrate compliance with California Building Code requirements for the building's occupancy type, size, and location.

Additions to existing commercial buildings require structural permits addressing both the new construction and its connection to the existing structure. Engineers must analyze the existing building's capacity to support additional loads and design connections that properly transfer forces between old and new construction.

Long Beach has mandatory seismic retrofit requirements for certain building types, including soft-story buildings and unreinforced masonry buildings. Retrofit projects require structural permits demonstrating compliance with applicable ordinances and California Building Code seismic requirements.

The Long Beach Development Services Department administers building permits through a structured process designed to ensure code compliance while facilitating efficient project delivery.

Before formal submittal, applicants can request pre-application meetings with Long Beach Development Services staff to discuss project scope, applicable codes, and potential issues. For complex commercial projects, this step helps identify requirements early and avoid surprises during plan check.

Our engineers respond to plan check comments promptly, typically within 5-7 business days, to maintain project schedules.

Long Beach has specific requirements beyond standard California Building Code provisions that affect commercial structural projects.

Permit timeline depends on project complexity, completeness of submittal, and current department workload.

| Project Type | Engineering | Plan Check | Total Timeline | |--------------|-------------|------------|----------------| | Simple Tenant Improvement | 2-3 weeks | 3-4 weeks | 6-8 weeks | | Complex Tenant Improvement | 3-5 weeks | 4-6 weeks | 8-12 weeks | | Commercial Addition | 4-6 weeks | 5-8 weeks | 10-15 weeks | | New Commercial Building | 6-10 weeks | 6-10 weeks | 14-22 weeks | | Seismic Retrofit | 4-8 weeks | 4-8 weeks | 10-18 weeks |

Commercial structural permit costs include both engineering fees and city permit fees.

| Project Type | Typical Engineering Fee | |--------------|------------------------| | Simple Tenant Improvement | $3,000-$8,000 | | Complex Tenant Improvement | $8,000-$20,000 | | Commercial Addition | $15,000-$40,000 | | New Commercial Building | $30,000-$100,000+ | | Seismic Retrofit | $10,000-$35,000 |

For a commercial project with $500,000 construction value, total city fees typically range from $15,000-$25,000.

Understanding common challenges helps project teams prepare and avoid delays.

Solutions include thorough existing conditions surveys, destructive investigation where necessary, and engineering approaches that accommodate uncertainty.

*"When our seismic retrofit project encountered unexpected existing conditions, AAA Engineering provided practical solutions that kept us on schedule. Highly recommend for Long Beach commercial work."* - Property Owner, East Long Beach

Typical commercial permits take 6-22 weeks total, depending on project complexity. Simple tenant improvements may be approved in 6-8 weeks, while new commercial construction typically takes 14-22 weeks. Complete, well-coordinated submittals receive faster review.

Structural permits are required when tenant improvements involve load-bearing walls, new floor or roof openings, heavy equipment requiring structural support, mezzanines, or changes affecting the building's lateral system. Minor cosmetic improvements typically don't require structural permits.

Yes. Long Beach has mandatory retrofit requirements for certain soft-story wood-frame buildings and unreinforced masonry buildings. Property owners must comply with ordinance deadlines or face penalties. Our engineers can evaluate your building and prepare retrofit plans if required.

No. Construction work requiring permits cannot begin until the permit is issued. Beginning work without permits can result in stop-work orders, penalties, and requirements to remove unpermitted work. However, demolition of non-structural elements may proceed under separate demolition permit in some cases.

Unpermitted work must be addressed as part of the permit process. Options include removing unpermitted work, obtaining retroactive permits (if work meets code), or incorporating corrections into the current project. Our engineers can evaluate unpermitted conditions and recommend approaches.

California law requires structural plans for commercial buildings to be prepared by a licensed Professional Engineer (PE) or licensed Architect. For most commercial structural work, a PE-stamped structural package is required for permit approval.

Required inspections include foundation, framing, and final inspections. Many commercial projects also require special inspections for structural concrete, steel, welding, and other critical work. Inspection requirements are listed on the approved plans and permit.

Projects involving designated historic buildings may use the California Historical Building Code, which allows alternative compliance approaches. However, any work must still achieve acceptable safety levels. Historic review may add time to the permit process.
