EstatePermit

Problem

Permit packages fail when rules live in different places: zoning maps, building code, environmental constraints, and utility capacity. A single missed citation delays a filing. The work does not parallelize well for a human reviewer.

Approach

• Five agents analyze zoning, building code, environmental, and utility rules in parallel, then a report agent compiles the package.
• Jurisdiction knowledge packs feed retrieval so claims come with citations, not vibes.
• Human approval gates sit on the path to export. An audit trail records who signed what.

Architecture

FastAPI owns orchestration, retrieval, and audit. React owns review: agent status, findings, and the approval flow. The split is deliberate so a city can swap a knowledge pack without rewriting the UI.

Outcome

The system is built for multi-city rollout rather than a one-off demo: pack-based rules, cited output, and a human in the loop. Work is ongoing.
