What is model-based building code compliance?
Model-based building code compliance means evaluating a design directly within the BIM model, rather than checking compliance after drawings are complete.
Traditionally, building code exists as text. Architects interpret requirements manually, cross-reference documents, and verify compliance during plan review or internal QA/QC. That process happens late, when issues are expensive to fix.
Model-based compliance changes when that check runs.
Instead of reading code and applying it manually, the code is translated into structured logic that evaluates directly against the model. Every flagged issue is tied to a specific element and cited to a code section — so teams can see what's wrong, why it matters, and how to resolve it.
Kestrel is built around this approach. It translates licensed building code data — including International Code Council (ICC) sources — into machine-executable logic that runs inside Revit. Checks take about 30 seconds and can be run continuously throughout design.
The shift this represents:
From documents to data
From manual interpretation to structured evaluation
From end-of-process checks to continuous feedback
Building code becomes something the model can understand.
Kestrel flags code compliance issues directly in the Revit model, with explanations and cited code references.
This is why Kestrel is the first structured compliance data layer for the built environment — compliance isn't a separate workflow, it's part of the design environment itself.
For a third-party perspective on how this category is developing, see /slantis's 2026 analysis of the QA/QC landscape in architecture. Kestrel is also listed on aec+tech and addd.io among tools for building code compliance in Revit.
