Definition
A Latin phrase meaning, literally, "not to be built higher." Altius non tollendi is a civil law servitude — a burden imposed on land or a building — by which the owner of a structure is prohibited from raising it beyond a specified height. The restriction runs with the property and benefits neighboring landowners or tenants who have acquired the right to light, air, view, or some other advantage that would be impaired by additional construction above the permitted level.
As a negative servitude, it does not require the burdened owner to do anything affirmative; it simply forbids a particular use — building upward past a fixed point. The right is typically established by agreement, by grant, or by the terms of a conveyance, and once attached to the land it binds successors in title.
Common Confusion
Altius non tollendi is sometimes confused with its mirror-image servitude, altius tollendi — the right to build higher than would otherwise be permitted, or higher than a neighboring structure. The two operate in opposite directions: altius non tollendi is a restriction on height; altius tollendi is a permission or easement to exceed ordinary height limits. Researchers encountering either term in historical sources should confirm which servitude is at issue before drawing conclusions about a property's rights or burdens.
Why It Matters in Research
This term appears almost exclusively in civil law jurisdictions and in scholarship tracing property concepts through Roman law to modern civilian systems. Researchers working in Louisiana, Quebec, or other mixed or civilian jurisdictions should treat it as a live doctrinal term, not merely a historical curiosity. In common law jurisdictions, the underlying concept survives — restrictions on building height, easements for light and air, restrictive covenants — but altius non tollendi as a term of art rarely appears in American or English case law outside of academic writing or comparative law contexts.
The critical research trap is assuming that because common law systems recognize functionally equivalent restrictions, the civilian concept maps cleanly onto familiar categories. It does not always do so. In Roman and civilian doctrine, servitudes are governed by strict rules of classification, and altius non tollendi belongs to a formal taxonomy of praedial (property) servitudes with specific consequences for creation, transfer, and extinction that differ from common law easement doctrine.
In historical sources, the entry in the Digest (8.2.4) is the foundational text. Researchers consulting pre-twentieth-century American treatises and dictionaries will find the term discussed primarily as a vehicle for explaining Roman servitude law rather than as a term in active domestic use. This limits its practical value in case research but makes it indispensable for understanding the intellectual framework behind nineteenth-century property scholarship.
Historical Dictionary Support
Black's first and second editions are in substantial agreement: both define the term as a civil law servitude restraining a homeowner from building beyond a certain height. The second edition adds useful precision by citing the Digest at 8.2.4 and Sandars's Institutes — references that allow researchers to trace the concept directly to Roman sources. Bouvier follows the same definition, adding no material variation.
What none of the historical dictionaries address is the practical mechanism of the servitude — how it was created, who could enforce it, or what remedies existed for violation. For those questions, the dictionary entries serve only as a starting point; the Digest text and civilian treatises are necessary to understand the doctrine in operation. The historical dictionaries also do not distinguish altius non tollendi from the neighboring concept of the servitude ne luminibus officiatur (not to obstruct light), though the two frequently appear together in civilian property arrangements and can overlap in effect.
Jurisdictional Note
In Louisiana, civil law servitudes including height restrictions are recognized under the Louisiana Civil Code, and the concept underlying altius non tollendi has practical legal relevance. In purely common law states, the term is of historical and comparative interest only; equivalent restrictions are analyzed under easement, restrictive covenant, or zoning law rather than servitude doctrine.
