coresidency

Coresidency is a term used to describe a situation in which two or more entities share a residence, base of operations, or jurisdiction. It is not tied to a single formal doctrine; its meaning varies by context. Generally, coresidency denotes overlap or shared footing rather than full fusion, and it often aims to optimize space, resources, or governance.

In housing and urban design, coresidency refers to arrangements where households live in a single building or complex while maintaining distinct legal identities. Models include co-housing, housing cooperatives, and intentional communities that share facilities and governance, yet preserve resident autonomy.

In governance and law, coresidency can mean overlapping residency obligations or multiple jurisdictions over a geographic area or a person. Border zones and treaty-based arrangements may subject residents to more than one regulatory framework, usually clarified by formal agreements on services and responsibilities.

In corporate or organizational contexts, coresidency may describe multiple legal entities operating from the same address or sharing administrative infrastructure, for efficiency or regulatory reasons. It also appears in discussions of multi-site operations and resilience planning.

Legal implications include residency verification, taxation, access to services, voting rights, and compliance with various regulations. When coresidency involves overlapping jurisdictions, intergovernmental agreements or compacts are typically used to allocate duties and resources and resolve disputes.
