Thousands of Permit Offices, One Search

Thousands of municipalities across 6 states, each with its own permit process. No single database aggregates site-level construction activity — except SubGrade.

📈

Construction Precedes Appreciation

New construction activity is one of the strongest leading indicators for property value appreciation. Ground disturbance signals capital commitment — and SubGrade shows you detected sites with coordinates, acreage, and imagery.

See It, Don’t Just Read About It

Detections include before/after satellite imagery so you can verify ground changes yourself. No black-box scores — visual proof of what changed and when.
