Kestrel by Kestrel Labs
Kestrel by Kestrel Labs is a BIM-native building code compliance platform that runs inside Autodesk Revit, flagging jurisdiction-specific violations on live models with cited code references in about 30 seconds per check.
Most teams still treat building code as a PDF exercise that happens after the model is largely fixed. Kestrel by Kestrel Labs moves that work into Autodesk Revit so you can see egress, fire separation, and accessibility conflicts while walls and doors are still easy to move.
The product combines Kestrel Compliance Analysis, which runs deterministic checks against ICC-backed code logic for your project type and location, with Kestrel Compliance Chat for cited answers tied to your model's occupancy, sprinklering, and jurisdiction. Every violation links to the specific Revit element and the code section behind it. Principals and project managers can review violation trends in the Kestrel web portal without opening a BIM file.
Coverage spans occupancy classification, height and area, construction type, means of egress, fire and life safety, accessibility, energy conditions, site overlays such as wildfire or flood zones, and local zoning triggers. Before each run, Kestrel proposes applicable codes (for example IBC, state amendments, and city overlays) from model context and waits for your confirmation. The vendor notes that permit delays can cost developers about $12,000 per day in carrying costs, which is why early model-side checks matter (Kestrel Labs, 2026).
Architects, interior designers, owners, and code consultants can use Kestrel from concept through construction documents. Firms buy an annual license sized to team scale and jurisdictional scope rather than per-seat metering, and smaller teams can start with a free trial through the Autodesk App Store or Trimble Marketplace.
Kestrel is built to support professional judgment, not replace it. Where code requires interpretation, the tool flags the condition and cites the reference instead of guessing, while continuous ICC data updates keep the rule library current.

Pros and cons
Pros
- Runs directly on live Revit models with element-level violation mapping
- Deterministic ICC-backed checks produce repeatable results on the same model
- Compliance Chat answers cite exact code sections tied to project conditions
- Web portal gives leadership visibility without opening Revit
- Firm-wide license avoids per-seat rationing during active design
- Free trial available through Autodesk and Trimble marketplaces
Cons
- Published pricing is quote-based; no flat public price list
- Host integration is Revit-focused; no verified support for ArchiCAD or other BIM authoring tools
- NFPA 101 and IECC coverage were still in development at time of research
- Jurisdictional coverage is expanding; confirm your location before relying on a project
- Full product documentation is gated behind the customer portal after onboarding
Key features
Revit-native checks: Run compliance analysis inside Autodesk Revit with no exports, redlines, or separate review files.
Cited violations: Each flagged issue maps to a specific model element with the IBC section, table, or amendment behind it.
Jurisdiction-aware context: Reads project location, occupancy, sprinklering, and type from the model, then proposes applicable code sets for your confirmation.
Kestrel Compliance Chat: Ask project-specific code questions in Revit or the browser with answers grounded in your model and cited to source sections.
Project dashboard: Track violation counts, run history, and compliance progress in a web portal for PMs and principals without Revit access.
Broad code categories: Covers height and area, construction type, occupancy, egress, fire and life safety, accessibility, energy, site environmental triggers, and zoning overlays.
ICC official data: Rule logic is built on licensed International Code Council content through the vendor's ICC Code Connect collaboration.
Continuous checking: Typical analysis passes complete in about 30 seconds, so teams can re-run after design reviews or option studies.
Firm-wide licensing: Annual license covers unlimited users, projects, and checks within the licensed firm rather than per-seat fees.
Marketplace distribution: Available via the Autodesk App Store and Trimble Marketplace for trial and rollout paths.

Frequently asked questions
How much does Kestrel by Kestrel Labs cost?
Kestrel is sold as an annual firm-wide license with quote-based pricing that reflects firm size, project mix, and jurisdictions served. The vendor does not publish a flat price list on its website. Plans are annual with optional monthly payment, and a free single-project trial is available through the Autodesk App Store or Trimble Marketplace.
Does Kestrel work on Mac or only Windows?
Kestrel Compliance Analysis runs inside Autodesk Revit, which means designers need a Windows environment where Revit is installed. Kestrel Compliance Chat and the project dashboard also work in a web browser, so PMs and principals can review compliance status without Revit on any machine with a modern browser.
Does Kestrel require exporting Revit files or support IFC?
Kestrel checks the native Revit model in place; the vendor emphasizes no exports or redlines for Compliance Analysis. Public materials focus on live Revit geometry and project metadata rather than IFC import workflows, so teams should plan around an active Revit model as the source of truth.
What building codes and jurisdictions does Kestrel check against?
Kestrel applies ICC-backed code logic based on your project type and location, including model codes such as IBC plus state and local amendments where supported. The vendor is actively expanding jurisdictional coverage and recommends scheduling a demo to confirm support for a specific city or state. NFPA 101 and IECC were listed as in development on the product FAQ.
How is Kestrel different from plan review or permitting software?
Plan review tools typically evaluate static PDF sets after design is largely complete. Kestrel runs against the live BIM model during design, mapping violations to Revit elements with cited references in roughly 30 seconds per pass. That lets teams fix egress or fire-rating issues before dependent rooms, sheets, and schedules are locked in.
Who is Kestrel by Kestrel Labs designed for?
The vendor targets architects, interior designers, owners and developers, and code consultants across concept, schematic design, design development, construction documents, and construction administration. Designers run checks in Revit, while project managers and principals can monitor violation trends in the web portal without opening the model.
Does Kestrel replace an architect's code review responsibility?
No. Kestrel performs first-pass compliance checks to surface checkable issues early and Compliance Chat explains how requirements apply to your project. Final interpretation, professional judgment, and design decisions remain with the licensed architect of record.
Is there a free trial for Kestrel?
Yes. You can start with a single-project trial by downloading Kestrel through the Autodesk App Store or Trimble Marketplace, installing the add-in, and running it on your model. Larger multi-jurisdiction firms are steered toward a demo so Kestrel can be configured for team access and jurisdictional scope.
