See how ZoningTrace reaches an answer.
Try the sample property, reveal its rule layers, and see which questions still need a town or site professional.
Every layer answers separately.
Illustrative result. A live product would resolve the actual parcel and current municipal sources before answering.
Toggle a layer to see how the answer depends on it.
A clearer answer without hiding the uncertainty.
ZoningTrace keeps statewide rights, municipal rules, parcel facts, and unresolved questions visible as separate parts of the decision.
Rule layers stay visible
State rights, local dimensional rules, overlays, transit proximity, and wastewater questions never collapse into one false yes/no.
Freshness is part of the answer
Every claim shows its source, retrieval date, and whether the town has newer material requiring review.
From address to a confident next call.
Each result ends with the facts you have, the questions you still need answered, and the source for both.
Confirm the parcel
Match an address to a parcel and let the homeowner correct a bad match.
Build the rule stack
Apply statewide ADU protections, then surface local restrictions and unresolved overlays.
Leave with a call sheet
Export the likely path, cited facts, unknowns, and exact questions for the building department.
Simple one-time pricing
