Source: States of Guernsey Island Development Plan (open GIS layers), read 2026-09-11. Matching is by map pin against the published boundary, so it is a strong indication and not a legal determination — a pin sits somewhere on a plot, not on its edges. Listings whose agents share a single parish-centre pin are left out entirely, because a shared coordinate cannot support a claim about one building.

The Main Centre boundary — the line that decides where most new development goes — is not here. The States publish it as an open line drawn on the landward side and closed by the coast, so turning it into an inside-or-outside test would mean inventing the sea edge. A wrong answer about the development boundary is worse than none.
