Tradition and practical correlate
The home’s rough facing, estimated from the street — 8-sector only; a precise facing needs a compass on site.
What the tool checks
A rough eight-sector facing estimate from the street direction.
What you can verify in person
Use a compass on site for a precise facing measurement.
Confidence and limits
This is deliberately an estimate. Street geometry is not a substitute for a compass reading at the home.
