Why the stack matters
Less anxiety. More visible progress.
The competitors prove the job exists. LotLight improves the moment between address and decision: every rule layer stays separately visible, sources stay attached, and the unknowns are named instead of averaged away.
SHEET 02
Rule layers stay visible
State rights, local dimensional rules, overlays, transit proximity, and wastewater questions never collapse into one false yes/no.
SHEET 03
Freshness is part of the answer
Every claim shows its source, retrieval date, and whether the town has newer material requiring review.
Registration order
