IRC Mechanical Compliance Review

What IRC Covers for Mechanical Review

One and two family dwellings and townhouses up to three stories, covering structural, mechanical, plumbing, and electrical provisions in a single residential code is what the International Residential Code covers. When it comes to mechanical review, the code mostly comes down to HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination. Mechanical engineers and MEP coordinators live in this territory day to day, and it's where most compliance risk actually sits.

Structured AI's QA/QC Compliance Checks run mechanical drawing sets against IRC provisions before anything leaves the office. Every check comes back with the exact page, the exact spot on that page, what's wrong, and how to fix it. It's a list your team can act on, not a confidence score they have to argue with.

Checks Structured AI Runs for Mechanical Review

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

• MECH-1: Equipment Tag Check
• MECH-5: Volume Damper BIM Check
• MAC-6: Utility and Service Coordination
• MECH-2: Equipment Details Check

These checks run alongside IRC-specific provisions covering HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination. The check library grows as firms define additional standards worth enforcing on top of baseline code compliance.

How Structured AI Reviews IRC Mechanical Compliance

Structured AI reads mechanical drawings in .pdf, .dwg, .rvt, or .ifc format and checks them against IRC provisions covering HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination. Every finding traces back to an exact sheet and location. On top of the baseline IRC checks, teams can write their own Custom Checks in plain English to catch firm specific standards too.

If the project lives in Revit, the Revit Add-In runs these mechanical checks straight against the live model, no export required, and reports back definite fails plus items worth double checking by element ID.

FAQ

Does Structured AI replace a licensed mechanical engineer's code review? No. These are pre submittal checks meant to surface likely IRC issues before they reach a plan reviewer or the field. They support a licensed professional's sign off and the jurisdiction's own plan review, not replace either one.

Which projects use IRC mechanical review? Projects in jurisdictions that have adopted IRC, where mechanical engineers and MEP coordinators need to confirm HVAC equipment sizing 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 mechanical 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.
