The best time to call a building is a month most trades never look for.
A commercial permit lands, the build runs for a year or so, and the doors open. The general contractor moves on. The warranty work winds down.
Two years after completion is when owners settle who services the equipment: the heating, the cooling, the systems somebody has to keep running. Be the call they get that month, not the one after.
Completion-dated, not guessed.
Diggby starts the clock from completion-dated records, not a guess from the permit date, and every row shows its source and when it was checked.
Take the Great Plains Warehouse Expansion in Calgary: $19.5M, completed May 17, 2024. Its two-year mark came this May, with the owner and the contractor on file.
Who it's for.
HVAC, mechanical and the other trades that keep a building running after the builders leave.
