How to Get Rack Designs Approved Faster: A Permit Workflow Guide

When a customer calls asking for an installation timeline, you already know how the conversation goes.

Prelims aren’t ready, your structural engineer is tied up on other jobs, and you haven’t even confirmed which AHJ covers the site. So you give the answer everyone dreads: “probably three to four weeks.” And even that is being optimistic.

It assumes your engineer turns things around in ten days, that the permit package goes in completely the first time, and that the AHJ doesn’t come back asking for seismic documentation that wasn’t included.

Most of the time, at least one of those assumptions fails.

There are three places where rack design approvals tend to slow down: documentation that isn’t ready before submission, PE stamp processes that drag on for weeks, and not knowing how your specific AHJ handles commercial rack installations.

This guide covers all three.

Where the Timeline Actually Gets Lost

A lot of contractors assume the AHJ is the problem, and while reviews do take two weeks or more in busy jurisdictions, most of the delay was already happening before anything got submitted.

The review process doesn’t begin until the full permit package reaches them.

Here is how the timeline actually goes:

Stage 1: Document preparation (structural calculations, PE-stamped drawings, LARC drawings, seismic analysis) can take anywhere from one business day to six weeks. If you have a structural engineer on call who knows rack systems and ANSI MH16.1, you can move through this quickly. If you are relying on a general structural engineering firm that picks up rack work on the side, six weeks is not out of the question.

Stage 2: AHJ intake and first review runs two to fifteen business days, depending on the jurisdiction and how complete your submission is. A thorough, well-organized permit package tends to move through faster. Some reviewers will prioritize it simply because it means less work on their end.

Stage 3: Comment response and resubmission if it gets triggered, adds two to six weeks per round.

One comment letter asking for corrected seismic documentation can easily double or triple your total approval timeline. This is the stage that turns a four-week project into a ten-week one.

Getting Stage 1 right is what everything else depends on. A complete, correct submission skips Stage 3 altogether, and that alone can save weeks. For a breakdown of what typically triggers rejections and comment letters, see common reasons for pallet rack permit rejections.

The Pre-Submission Checklist That Eliminates Rework

Most packages that come back with comment letters are usually missing the same things every time. Before you submit, check yours against this list.

1. Structural calculations

Calculations should reference ANSI MH16.1, cover load combinations for beam, column, and brace members, and confirm that each component’s utilization ratio is within allowable limits. Generic estimates are not accepted by most AHJs. All calculations must be based on the actual components specified for the installation.

2. PE-stamped drawings

In most commercial jurisdictions, rack permit drawings need to be stamped and signed by a licensed Professional Engineer (PE) registered in the state where the installation is happening. A stamp from the wrong state will get you rejected. Check the licensing requirements for your jurisdiction before you submit. See pallet rack permitting requirements vary by state.

3. LARC drawings (Load Application and Rack Configuration)

LARC drawings need to show plan and elevation views of the rack system with load values clearly marked at each storage level.

What’s shown in the drawing has to match the actual field installation plan. A mismatch between the two is one of the most common reasons packages get sent back.

4. Seismic analysis documentation

If the site falls in Seismic Design Category C through F under the International Building Code, the permit package needs seismic force calculations for the rack system. Missing seismic documentation in a seismic zone is an automatic rejection in almost every jurisdiction. It’s worth confirming your site’s seismic zone before you start pulling documents together.

5. Manufacturer-certified component data

Most AHJs want manufacturer-certified load ratings for uprights and beams, not just calculated values. Have certified data sheets ready for every component before you submit.

6. Site plan with rack layout

A dimensioned floor plan showing rack placement, column lines, egress paths, and fire suppression system. Some jurisdictions also require rack-to-building clearance documentation.

7. Applicable code references

Make sure your calculations reference the correct edition of the IBC your jurisdiction has adopted, along with the matching ANSI MH16.1 edition. Requirements change between code cycles, and submitting calculations tied to an outdated edition is an easy way to avoid rejection.

How to Get a PE Stamp Without Waiting Weeks

For most manufacturers and integrators, waiting on a structural engineer is where the most time gets lost. The process usually goes like this:

1. Design gets finalized
2. Sent to a structural engineer for load calculations and drawings
3. Goes through a revision cycle
4. Sent for PE stamping

That whole process can take ten to fifteen business days if things go smoothly, though three to four weeks is more common, and that is before anything reaches the AHJ. Every beam, column, and brace member has to be checked, seismic forces calculated, and utilization ratios verified against ANSI MH16.1. None of that can be skipped or rushed.

That is exactly what OneRack was designed for. Developed by licensed Professional Engineers at Epiq Engineering, it runs FEA on real manufacturer parts, checks every member against ANSI MH16.1, and produces engineer-verified calculations as part of the design process. That earned OneRack the MHI 2023 Innovation Award.

When a PE stamp is needed, OneRack handles that too, with a typical turnaround of 2 to 5 business days. Not sure if your project needs one? This page covers when stamped drawings are required.

Compare the timelines:

• Traditional path to PE-stamped drawings: 10 to 30 business days
• OneRack path to PE-stamped drawings: 1 day for document generation + 2 to 5 business days for stamp = 3 to 6 business days total

When to Request a Pre-Application Meeting

Most rack professionals skip the pre-application meeting, also called a pre-submittal conference, for certain projects that are worth reconsidering.

In a pre-app meeting, you walk an AHJ plan reviewer through your project scope before the formal submission goes in. They can flag documentation requirements specific to their office that are not published anywhere, and you can ask about seismic interpretation, accepted calculation formats, and anything jurisdiction-specific that would otherwise show up as a comment letter.

Pre-app meetings are worth scheduling when:

• The installation is in a seismic zone you haven’t worked in before (Seismic Design Categories C through F)
•  You have never submitted to this particular AHJ before
• Rack heights exceed 25 feet
• The project involves multiple buildings, phases, or a complex structural interface with the building itself
• You’ve already received a comment letter on a similar project from this AHJ

For standard installations in jurisdictions you know well, you probably do not need one.

Pre-app meetings add a week or two upfront, but each comment-response round that gets avoided saves two to four weeks. On a complex job in an unfamiliar jurisdiction, it is usually time well spent.

How to Handle AHJ Review and Comment Responses Faster

After you submit, there are a few things worth doing rather than just waiting.

Step 1: Confirm receipt. Call or email the plan review office on submission day to confirm they received the package and ask for an expected turnaround date. Do not assume an online portal submission was received and logged correctly.

Step 2: Respond to comment letters fast. If a comment letter comes back, respond within 48 hours. Reviewers who are still fresh on a project move resubmissions faster. One that comes back three weeks later often gets treated like a new submission.

Step 3: Send a written response with your revised drawings. Address each comment directly in writing, not just in the revised drawings. If they asked for seismic calculations, state exactly where they appear: “Seismic force calculations have been added to Sheet S-3.” Revised drawings alone are one of the most common ways to end up in a second review cycle.

Step 4: Ask about expedited review. Some jurisdictions offer it for an additional fee, usually 50 to 100 percent on top of standard permit costs. If the installation is time-sensitive, it is worth asking about.

The Fastest Path from Design to Approved Permit

Traditional path:

Stage	Time
Design finalized	Day 1
Sent to the structural engineer	Day 2
Calculations and drawings received	Day 10–30
PE stamp submitted and received	Day 20–45
Permit package compiled and submitted	Day 21–46
AHJ first-round review	Day 26–71
Comment response round (if triggered)	Day 40–100+
Permit issued	Day 40–100+

Compressed path (complete documentation, structured PE stamp workflow):

Stage	Time
Design finalized + calculations generated	Day 1
PE stamp submitted	Day 1
PE-stamped drawings received	Day 3–6
Permit package compiled and submitted	Day 4–7
AHJ first-round review (complete submission)	Day 9–22
Permit issued	Day 9–22

Looking at both tables, the AHJ review window is roughly the same in both scenarios. The difference between a 40-day timeline and a 9-day one has nothing to do with the AHJ. The pallet rack permit process has not changed, but how prepared you are going in makes all the difference.
