Definition
Egress is the right or ability to exit a property or pass outward from an enclosed or bounded space. In property law, egress refers specifically to the legal right to leave land — whether one's own or another's — and is most commonly encountered as part of the easement phrase "ingress, egress, and regress," which collectively describes the full bundle of rights to enter, exit, and return across a parcel.
In the easement context, egress means the right to pass outward over another's land. A landowner whose property is landlocked or whose practical access depends on crossing a neighbor's parcel may hold an easement of egress entitling them to leave their land across the servient estate. Egress rights may arise by express grant, implication, necessity, or prescription.
In landlord-tenant and building code contexts, egress refers to a means of exit from a building or unit — a physical pathway (door, window, stairwell) sufficient to allow occupants to leave safely. This usage is largely a statutory and regulatory matter.
Common Language
Modern common usage (Wiktionary): An exit or way out; the process of exiting or leaving.
Historical common usage (Webster's 1913): The act of going out or leaving, or the power to leave; departure.
The gap between common and legal meaning is narrow but consequential. In ordinary language, egress is simply the fact or act of leaving. In property law, it is a right — a legally recognized entitlement to exit across land one does not own. A researcher who reads "egress" in a deed or easement instrument as mere physical departure will miss that it describes a legal interest attached to land.
Recognized Forms
/SUBTYPES
Egress appears in practice most often within two compound formulations:
Ingress, Egress, and Regress: The traditional tripartite phrase appearing in easement grants and deeds. Ingress is the right to enter; egress, the right to leave; regress, the right to return. Together they establish an unrestricted right of access across the servient estate.
Emergency Egress: A building code and fire safety concept establishing minimum physical requirements — window size, door clearance, stairwell access — for occupants to exit a structure during an emergency. Distinct from easement egress; governed by statute and ordinance rather than deed.
Why It Matters in Research
Researchers working with deeds, easement instruments, or access disputes will encounter egress as one of a formulaic trio. Because the three terms — ingress, egress, regress — were historically used together as a complete phrase, finding only "egress" alone in an older instrument may signal a drafting irregularity or an incomplete transcription worth tracing.
In historical sources, Anderson's simply redirects to INGRESS, reflecting the conventional understanding that the terms always travel together and that ingress is the conceptual anchor of the trio. This cross-reference structure means researchers consulting historical dictionaries for egress will need to read the ingress entry to get the full doctrinal picture.
A second research trap: egress in building code and landlord-tenant materials (particularly twentieth-century statutes and municipal codes) has developed into a largely independent technical vocabulary around physical exit pathways. Searching for "egress" across a broad corpus without filtering for context will return results from both the easement tradition and the building code tradition — two bodies of law with different sources, different remedies, and different governing authorities.
Jurisdictional variation matters in the access-by-necessity doctrine, which is the most litigated context for egress easements. Some states impose stricter necessity standards; others recognize implied easements from prior use more generously. The specific rights bundled under "ingress, egress, and regress" when those words appear in a grant may also be construed differently depending on the jurisdiction's easement law.
Historical Dictionary Support
The historical dictionaries are thin here. Anderson treats egress as a pure cross-reference, offering no independent definition — a signal that nineteenth-century American legal usage treated egress as inseparable from ingress and regress, not a freestanding concept. Bouvier provides a brief but substantive entry: the right to go upon land from time to time as required to assert a right, citing the taking of emblements (crops) as an example. This is useful because it reveals that historical usage extended beyond simple transit — egress could support the exercise of a property right, not merely the act of crossing land.
Both sources reflect an era when egress appeared almost exclusively in the real property context. Neither addresses the building code or statutory safety usage, which postdates these dictionaries entirely. Researchers using historical dictionaries to interpret a modern lease or municipal code provision about egress windows or exit pathways will find no guidance there and should not expect to.
Jurisdictional Note
Egress easements by necessity are recognized in all U.S. jurisdictions but on varying terms — some states require strict landlocking with no alternative access; others allow necessity to be established by showing that existing access is substantially impractical. In the United Kingdom and Commonwealth jurisdictions, the terminology and doctrinal framework differ; "right of way" is more commonly used than the ingress-egress-regress formulation.
