Fence rules for corner lots

A corner lot carries a rule an interior lot does not: a wedge of ground near the intersection where nothing tall may stand, so a driver can see across it. It goes by several names, the vision triangle, the sight triangle, the clear view area. It is almost always municipal, and it has a habit of living in the traffic title rather than the zoning title, which is why a fence chapter can point at it without ever naming it.

What this page does not cover

Everything above is state law. Fence height, setback, corner visibility and materials are set by city and county ordinance in almost every state, and a local rule can be far stricter than the statewide default. A parcel can also carry an easement, an overlay district, a fire hazard zone or a recorded HOA restriction, none of which appear in a statute.
