AI Impact Scoring
Every permit is classified by our AI into three severity tiers. A bathroom remodel scores differently than a 12-story mixed-use development. The scoring factors in project scope, proximity to your address, and permit type — so you immediately see what affects your daily life.
Filter by type, severity, and date
Narrow the map to exactly what you need. Show only high-severity permits filed in the last 30 days. Or focus on new construction vs. renovations. Each filter updates the map in real-time.
