Building Code Agent
State-scoped retrieval over adopted building-code sources—plain-language answers, citations, and low-confidence cues in the browser.
For architects, engineers, consultants, and facilities teams who need conversational access to building-code context across jurisdictions—scoped by state—with verification against official adoption and your AHJ.
Stack playground
Send test questions through the in-app Building Code lab (session-aware internal RAG with citations). You'll choose a jurisdiction first—no default state—then chat.
Open Building Code labWhy This Stack?
Reading dense code sections against a deadline is slow and error-prone. A retrieval-augmented assistant keeps replies anchored in indexed excerpts (edition, amendments, scoped by state where configured) rather than guessing from raw model memory alone.
Limitations
-
Not legal or engineering advice. Outputs depend on your indexed material and model settings; always verify against official code and your Authority Having Jurisdiction (AHJ).
-
Which states respond follows your ingestion and rollout configuration (see
BUILDING_CODE_STATES/ enablement).
Estimated Monthly Cost

| Embeddings + LLM | Provider + model tier | Varies |
Total depends entirely on corpus size, throughput, and model choices.
