$/sq ft typical Southern California industrial / warehouse construction & expansion planning range (2025–2026)
City of Industry + LA County Permits
Expansions and modifications generally require a City of Industry Development Plan (Long Form for larger or more complex projects; Short Form for certain smaller or CEQA-exempt work). Design Review applies. Building permits and plan check are processed through Los Angeles County Building & Safety (BSOP) after planning approval. Grading, industrial waste, and right-of-way permits may also apply.
Industrial Building Stock & Operations
City of Industry is dominated by tilt-up concrete, warehouse, manufacturing, and distribution facilities, many with dock-high loading, high clear heights, and supporting office areas. Additions must match structural systems, exterior panels or finishes, and often maintain continuous operations with phased construction and temporary dock or access routes.
One License, Multi-Trade Coordination
B-license general contracting plus C-33 painting lets us self-perform or tightly coordinate foundation, structural framing or tilt-up panels, roofing, MEP, dock equipment, exterior coatings, and interior finishes — essential for schedule-driven industrial expansions.
Industrial Corridor Reality
High-intent demand centers on warehouse and industrial building expansions along major corridors, cold-storage and specialized manufacturing additions, and supporting office or mezzanine growth. Operations-phased work, truck circulation, and minimal disruption to active facilities are standard expectations.
Our City of Industry Addition Process
Assessment
On-site review of the existing industrial or commercial building, site circulation, dock configuration, structural system, and expansion goals. We identify planning, structural, and operational constraints early. Pasadena HQ supports efficient mobilization into the City of Industry corridor.
Design & Engineering Coordination
Architectural and structural coordination for the addition, civil and grading as needed, Title 24 energy compliance, and clear scope covering foundation, structure, roof, MEP, docks, exterior matching, and finishes. Pricing presented as planning ranges with on-site confirmation.
Planning & Permits
We prepare and support City of Industry Development Plan and Design Review submittals, then LA County Building & Safety plan check and permit issuance. Trade permits, grading, and industrial waste or sewer clearances are coordinated as required.
Execution
Phased construction with operations continuity where required — temporary barriers, alternate dock or truck routes, dust and noise controls. Foundation, structure, roofing, MEP, exterior envelope, and finishes sequenced under one project manager.
Walkthrough & Close-Out
Final inspections, Certificate of Occupancy or final sign-off coordination, punch list, as-built notes, and warranty handover aligned with facility operations and owner schedules.
Projects staged from our Pasadena headquarters for reliable response across City of Industry industrial corridors and surrounding markets.

Are there special requirements for industrial expansions?
Yes. Projects must comply with industrial zoning standards (setbacks, height, parking, lot coverage), Design Review criteria, CALGreen and construction & demolition debris requirements, and any industrial waste or stormwater conditions. Operations-phased construction and truck circulation planning are common expectations for active facilities.

Do SCAQMD and Title 24 rules apply?
Yes. City of Industry is within the South Coast AQMD; architectural coatings must meet Rule 1113 VOC limits. Additions trigger Title 24 energy compliance for new conditioned space and affect envelope and systems documentation. We specify compliant materials and coordinate required reports.
