Propertyadjacent

Propertyadjacent is a term used to describe the relationship between two properties that share a boundary or are located next to one another. It is not a standardized legal or technical term, but it appears in discussions of land parcels, urban planning, and data modeling to express direct adjacency or proximity.

In real estate and land administration, two parcels are propertyadjacent if they share a common border, corner, or point. This adjacency can affect rights of access, easements, taxation, zoning, development potential, and parcel-based governance. The concept is central to cadastral surveys and neighborhood planning, where understanding which parcels touch or nearly touch informs decisions about infrastructure, services, and regulatory compliance.

In geographic information systems and cadastral databases, propertyadjacent can be represented as an edge in an adjacency graph, with each parcel as a node and shared boundaries forming links. Data quality, boundary resolution, and the legal definitions of “sharing a boundary” (full, partial, or corner) influence how adjacency is recorded and used in proximity analyses, risk assessments, and parcel-level planning.

In ontology or data-modeling contexts, propertyadjacent may be defined as the symmetric, irreflexive relation between two property entities that touch at any boundary. It is related to, but distinct from, nearby, contiguous, or overlapping relations, depending on the domain’s topology rules.
