IRC Civil Compliance Review

What IRC Covers for Civil Review

the International Residential Code governs one and two family dwellings and townhouses up to three stories, covering structural, mechanical, plumbing, and electrical provisions in a single residential code. For civil review specifically, the parts that matter most are grading, drainage, utility coordination, and site civil compliance. That's where civil engineers carry the most compliance risk, and where plan check comments most often start.

Before a set goes out, Structured AI's QA/QC Compliance Checks review civil drawings against IRC. The output is deterministic: exact page, exact location, the issue, and the fix. No confidence percentage to second guess, just a list the team can sign off on.

Checks Structured AI Runs for Civil Review

Structured AI's check library includes named, specific checks relevant to civil review, drawn from the same library used across every project regardless of which code applies. A sample of checks commonly relevant to civil drawing sets:

• CIV-21: Boundary Grade Matching Check
• CIV-13: Sight Triangle Check
• CIV-4: Demolition Plan Check
• CIV-22: Gutter Slope Compliance Check

These checks run alongside IRC-specific provisions covering grading, drainage, utility coordination, and site civil compliance. The check library grows as firms define additional standards worth enforcing on top of baseline code compliance.

How Structured AI Reviews IRC Civil Compliance

For civil sets in .pdf, .dwg, .rvt, or .ifc, Structured AI runs IRC checks focused on grading, drainage, utility coordination, and site civil compliance, with each finding tied to an exact sheet and location so it's easy to verify. Firms that want more than the baseline IRC coverage can write Custom Checks in plain English on top of it.

For IRC projects modeled in Revit, the Revit Add-In runs the same civil checks directly against live geometry, flagging definite fails and items to verify by exact element ID. Nothing needs to be exported first.

FAQ

Does Structured AI replace a licensed civil engineer's code review? No. This is a pre check step, built to catch likely IRC issues early. It doesn't replace sign off from a licensed professional or the jurisdiction's plan review process, it just gives both a shorter list to start from.

Which projects use IRC civil review? Projects in jurisdictions that have adopted IRC, where civil engineers need to confirm grading compliance before permit submittal or during design development.

How is this different from a general IRC check across all disciplines? This page is scoped to civil provisions specifically. Structured AI's check library covers every discipline and every code a firm works with, so the same deterministic, source-linked review runs across a full drawing set rather than one discipline at a time.
