AI-Assisted Plan Review for AHJs and Third-Party Reviewers
Helonic is an AI construction drawing analysis platform for Plan Reviewers doing Pre-Permit Review.
Apply the same code rigor to every submittal regardless of reviewer workload.
What is pre-permit review for plan reviewers?
Pre-permit review for plan reviewers is the completeness and code pass Helonic runs on a permit PDF so every submittal gets the same first check before the examiner writes comments. AI-assisted review helps reviewers maintain consistent depth across the submittal volume by handling the dimensional and citation-based checks that pattern-match well, leaving reviewer attention for the judgment-heavy items.
Why do plan reviewers struggle to keep review depth consistent?
Plan reviewers have to enforce code the same way on every submittal, but workload and volume often force them to skip items. Some reviewers see every detail; others see only the headline items. AI-assisted review provides a baseline of consistent depth so every submittal gets the same systematic check.
How does Helonic help plan reviewers with pre-permit review?
Helonic gives every permit submittal the same first pass, so a busy week does not drop the slope check or the edition check.

Reviewer time on the hard calls
The examiner's time goes to the comment that needs a judgment, because the measurable checks are already listed.
Documentation of review
Each submittal keeps a record of which checks ran and which findings were accepted.
Inter-reviewer consistency
Two examiners opening the same set see the same baseline list before either one adds a comment.
What issues does Helonic catch in pre-permit review for plan reviewers?
Helonic flags these pre-permit review issues when plan reviewers review a set:
Accessible route slope exceeds 1:12 - ADA correction notice candidate
Egress travel distance exceeds 250' - IBC correction
ASCE 7 edition cited doesn't match jurisdiction adoption
Sprinkler hazard classification missing for storage area
Code summary cites prior IBC edition
Stair pressurization shown on mechanical but missing from life-safety narrative
Which Helonic features matter for pre-permit review?
Helonic includes Multi-code parallel verification when plan reviewers run this workflow.
Multi-code parallel verification
Adopted-edition awareness with local amendments
Dimensional compliance recomputation
Cross-discipline coordination check

How do plan reviewers run a pre-permit review?
Helonic reads the permit PDF at intake and runs the dimensional and citation checks across the codes the jurisdiction adopted.
Receive submittal
Helonic reads the permit PDF at intake and runs the dimensional and citation checks across the codes the jurisdiction adopted.
Run AI baseline review
Accessible slopes, travel distances, adopted editions, and missing life-safety notes are listed with the sheet and the section.
Reviewer focuses on judgment items
The examiner spends the review on occupancy, alternate methods, and the comments that need a judgment call.
Generate correction notice
Accepted findings export with the code citation so they can go into the correction letter.
What do practitioners say about pre-permit review for plan reviewers?
“Plan reviewers we interviewed described AI-assisted review as the practice that would most consistently improve review quality across a department. Variability between reviewers reduces; consistency improves.”

What do plan reviewers ask about pre-permit review?
Can this replace plan reviewers?
Helonic augments plan reviewers rather than replacing them. Code interpretation, professional judgment, and negotiation with applicants still require human reviewers.
Does this work for jurisdictions with local amendments?
Helonic supports custom rule packs for jurisdiction-specific amendments.
Is the audit trail admissible for appeals?
Helonic produces a structured record of checks performed. Whether it's admissible in appeals depends on jurisdiction policy.
