Search a covered address on MapMyLot to see the straight-line distance from the property boundary to the nearest mapped high-voltage transmission corridor. The reading helps you identify nearby infrastructure and questions to investigate; it does not measure exposure or establish a safe distance for a home.

The distance is measured from the parcel's full boundary geometry, not its centroid - a large block can have one edge much closer to a corridor than the middle of the lot suggests, and centroid-based measurement would understate that. The 33kV threshold defines which mapped transmission infrastructure this readout includes; ordinary low-voltage lines serving individual streets are not flagged, since almost every property has one nearby and it would make the signal meaningless.
It is a straight-line measurement to the nearest mapped corridor edge, not a health or safety assessment and not a valuation. Research on proximity to high-voltage infrastructure and property values is genuinely mixed, and any effect depends heavily on the specific line, the specific market, and whether the line is visible from the property. Treat the distance as a starting point for your own research, a conversation with your lender, and (where it matters to you) independent advice - not a verdict.

A lookup with no powerline reading means no mapped 33kV+ corridor was found nearby, not a guaranteed absence.
Power lines are one of six proximity signals MapMyLot surfaces automatically from a single address search. See the proximity overview for how distance to flood zones, the coast, and parks are calculated the same way, jump straight to the flood zone check guide, or check a property's distance to the nearest lake or water body.
Always confirm anything material to a purchase or finance decision with the relevant authority or your lender directly.
No. Distance to a mapped corridor is not a measurement of electric or magnetic fields at a house. For health information, consult ARPANSA's powerline guidance. For building clearances and easement conditions, contact the network operator and check the property documents.
