About Kestrel Labs
Compliance is the last part of architectural practice that hasn’t been restructured around BIM. The rest of the design process moved into the model decades ago. Code didn’t.
Architects still read PDFs, mark up drawings, and catch expensive errors at plan review, after decisions have already compounded. That’s the gap Kestrel is closing.
Building code should be computable.
What we’re building
Kestrel is building code compliance software for architects.
It runs inside Revit, evaluates BIM models against jurisdiction-specific requirements, and ties every issue to model geometry with a cited code reference.
Checks take about 30 seconds. Teams run them continuously during design, not once at the end.
Under the hood, Kestrel translates building code into structured, machine-executable logic. That’s what allows compliance to run directly in the model.
Why now
BIM is now the standard substrate of practice, which means compliance can be evaluated against structured geometry instead of static drawings.
At the same time, advances in AI have made it possible to translate large bodies of regulatory text into executable logic at scale.
The industry is starting to shift. In a 2026 survey of the QA/QC landscape, the architectural firm /slantis placed Kestrel in the first tier of model-side compliance tools:
“Instead of treating accessibility, fire separation, or zoning review as something that only happens at the end, these tools surface issues while the model is still being developed.”
What we believe
Building code is a rule system, not just a document.
Compliance should happen during design, not after
Requirements should be tied to model geometry
Every issue should be backed by a cited source
The tool should take the tedious work off the architect’s plate, not design decisions
