Frequently Asked Questions
How accurate is the AI diagnostic?
Sentinel uses GPT-4o with state-specific code context and RAG-retrieved code sections. It identifies compliance risks that would typically require a licensed code consultant. Results should be verified by a qualified professional before submission to authorities.
Which building codes are covered?
We cover all 50 US states with 774+ code entries including IBC, IRC, IFC, IMC, IECC, NEC, and state-specific amendments. City-level codes are available for 237 major cities and 250 counties with independent enforcement.
Can I use this for permit applications?
Sentinel identifies required permits, estimates fees, and provides direct links to jurisdiction application portals. The diagnostic report can supplement your permit application but is not a substitute for stamped drawings by a licensed professional.
How does the client portal work?
Generate a secure token-based link for any project. Clients can view compliance status, proposals, and timelines without creating an account. Links expire automatically (1-30 days configurable) and can be revoked anytime.
What's included in the Enterprise plan?
API access for integrations, custom RAG document ingestion (upload your own code documents), SSO/SAML authentication, dedicated account manager, 99.9% SLA, and volume discount pricing. Contact our sales team for a custom quote.

CODE FACT OF THE WEEK
Did you know? Boston's BERDO 2.0 now requires all buildings over 20,000 sq ft to report annual emissions. Non-compliance penalties start at $150/ton of excess CO2. Sentinel flags BERDO requirements automatically for any Boston address.
