Get Your Permits Right the First Time. Or Watch Your Timeline Disappear.

Permit rejections add months to project timelines and thousands in costs. Missing documents, incomplete calculations, fire code oversights—each mistake sends you back to square one.

High pile storage analysis that passes review.

Storage above 12 feet with combustible materials triggers high-pile permit requirements in most jurisdictions. That means commodity classifications, sprinkler assessments, aisle width verification, and fire department access documentation.

We prepare complete high-pile storage analyses that satisfy your fire marshal: commodity class determinations, storage configuration details, sprinkler adequacy evaluations, and compliant floor plans. No surprises at inspection.

Seismic Engineering for Every Zone

From California's strict seismic requirements to zones most people don't realize have them (Missouri, South Carolina, even parts of New York), rack systems need engineered seismic calculations to get permitted.

Our engineers provide site-specific seismic analysis based on your location's design category, soil conditions, and load profiles—with calculations that meet current ANSI MH16.1 and IBC requirements.

Permit Submission & Follow-Up

We prepare the complete permit package and can manage submission on your behalf. When the AHJ has questions, we respond. When inspections are scheduled, we support.

Seismic Calculations

Site-specific seismic analysis meeting ANSI MH16.1 and IBC requirements. We account for seismic design category, soil classification, load profiles, and anchor requirements—with engineer-stamped documentation.

High Pile Storage Analysis

Complete high-pile combustible storage analysis: commodity classifications, storage heights, aisle configurations, sprinkler adequacy, and fire department access. Documentation that satisfies your fire marshal.

Structural Load Calculations

Load capacity calculations for racking systems, mezzanines, and pick modules. We verify that your floor slab can handle the concentrated loads and that your systems are rated for your actual products.

CAD & Permit Drawings

Detailed CAD drawings ready for permit submission: floor plans, rack elevations, aisle dimensions, fire protection locations, and load placards. Formatted to meet your jurisdiction's specific requirements.

common questions

Frequently asked questions

When do I need a permit for warehouse racking?

Requirements vary by jurisdiction, but most areas require permits for racking over 5'9" to 6' in height. If you're storing above 12 feet, you'll likely need both a building permit (with seismic calculations) and a high-pile storage permit. We assess your specific situation and identify exactly what's required.

What is a high-pile storage permit?

High-pile storage permits regulate the storage of combustible materials above certain heights—typically 12 feet, though some jurisdictions require them at 6 feet for high-hazard materials. The permit ensures your storage configuration doesn't create unmanageable fire risks: proper sprinkler coverage, adequate aisle widths, fire department access, and appropriate commodity separation.

What documents are typically required for a rack permit?

Common requirements include: engineer-stamped seismic calculations, CAD drawings showing rack layout and elevations, load capacity documentation, anchor specifications, high-pile storage analysis (if applicable), fire protection coordination documents, and jurisdiction-specific application forms. Requirements vary significantly by location.

How long does the permit process take?

Timeline depends on jurisdiction and project complexity. Simple rack permits in smaller jurisdictions may take 2-4 weeks. Complex projects in larger cities with high-pile requirements can take 2-3 months. Our 97% first-submission approval rate eliminates the rejections that typically add months to DIY timelines.

What are seismic calculations, and why do I need them?

Seismic calculations determine whether your rack system can withstand earthquake forces without collapse. They account for your location's seismic design category, soil conditions, rack configuration, and load weights. Most jurisdictions require PE-stamped seismic calculations for rack permits—even areas you might not consider earthquake-prone.

Do I need seismic calculations outside of California?

Yes, many areas require them. Parts of Missouri, South Carolina, Tennessee, Utah, Nevada, Washington, Oregon, and even New York have seismic requirements. The IBC divides the country into Seismic Design Categories (A through F)—and any category above A may require engineered seismic analysis.

What's involved in a high-pile storage analysis?

We evaluate: commodity classifications (Class I through IV, plus high-hazard categories), storage heights and configurations, rack types and dimensions, aisle widths, existing fire suppression systems, fire department access, and any hazardous materials storage. The result is a comprehensive report and floor plan that satisfies fire marshal requirements.

Can you help with existing buildings, or only new construction?

Both. We regularly help companies moving into existing warehouses assess permit requirements and prepare documentation. We also support expansions, reconfigurations, and changes of use that trigger new permit requirements.

How does your permitting process work?

We start with a project assessment to understand your storage plans, building conditions, and jurisdictional requirements. We then prepare all required documentation—calculations, drawings, analyses—and compile a permit-ready package. We can submit on your behalf or hand off for your team to submit. Throughout the review process, we respond to AHJ questions and support inspections.

Do you work with our architect or GC?

Absolutely. On new construction projects, we coordinate with your design team to ensure rack systems integrate properly with the building design and that fire protection is appropriately specified. We provide the warehouse-specific engineering documentation that supplements the broader project plans.

What information do you need from us to get started?

We'll need: building dimensions and clear heights, planned rack layouts (or we can help design them), product information (weights, commodity types), existing fire protection details, and your project timeline. The more detail you can provide upfront, the faster we can prepare accurate documentation.

Do you handle the permit submission, or do we?

Either way. We can prepare the complete package for your team to submit, or we can manage submission and follow-up on your behalf. Many clients prefer to hand off the entire process—let us deal with the permit office while you focus on your operation.
