Definition
A small building or structure belonging to and associated with a main dwelling or messuage, but standing apart from it. In legal contexts, the term encompasses any ancillary structure serving the ordinary necessities of life — barns, stables, dairies, smokehouses, and similar outbuildings — so long as it is connected by use and proximity to the principal dwelling. The precise scope of the term carries significant consequences in criminal law, particularly in defining the extent of a dwelling for burglary purposes.
Common Language
Modern common usage (Wiktionary): An outbuilding, typically permanent, containing a toilet or seat over a cesspit; also used more broadly for any small structure located apart from a main building.
Historical common usage (Webster's 1913): A small house or building at a little distance from the main house; an outbuilding.
The common meaning has narrowed sharply in modern American usage: most speakers today use "outhouse" to mean specifically a privy or toilet structure. The legal meaning is and historically has been considerably broader, encompassing any functionally associated outbuilding regardless of its purpose. A researcher encountering "outhouse" in older legal materials should not assume the sanitary facility meaning; the term likely refers to a barn, stable, or similar structure whose inclusion within the curtilage or dwelling definition is the point at issue.
Common Confusion
"Outhouse" and "curtilage" are related but not interchangeable. Curtilage describes the legal concept of the enclosed land and appurtenant structures surrounding a dwelling that receive the dwelling's legal protections. An outhouse, in the older legal sense, is one type of structure that may or may not fall within the curtilage depending on proximity, use, and enclosure. The two terms address different questions: curtilage is a spatial and legal zone; outhouse is a description of a physical structure. Additionally, "outbuilding" is the modern neutral term that corresponds most closely to the broad historical legal meaning of outhouse.
Why It Matters in Research
The primary arena in which historical sources develop this term is burglary law, where the common law required careful analysis of whether a structure was a dwelling house or sufficiently connected to one to bring it within the offense. Whether an outhouse qualified — and under what conditions — was contested doctrine, and the answer determined the severity of the charge.
Researchers working in 19th-century criminal law materials will find "outhouse" doing real analytical work in burglary cases and commentary. The term appears in discussions of whether breaking into a barn, stable, or dairy house at night constituted burglary of a dwelling. This analysis fed directly into the development of curtilage doctrine.
The modern popular meaning (privy) can mislead researchers skimming older sources. A case or treatise discussing burglary of an "outhouse" is almost never discussing a toilet structure — it is analyzing the relationship between an ancillary building and the main dwelling.
State codifications from the 19th century sometimes enumerated outhouses explicitly in burglary statutes, creating variation in how broadly or narrowly the term was defined by jurisdiction. When researching a specific historical case, the applicable state's statutory definition (if any) controls over the common law gloss.
Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) defines outhouse as "any house necessary for the purposes of life, in which the owner does not live." This formulation emphasizes functional necessity and non-habitation as the defining characteristics — the outhouse serves life's needs but is not itself a residence. This is a workable but imprecise standard that would have required case-by-case application.
Burrill's Law Dictionary offers the more precise and structurally useful definition: a small house or building belonging to a messuage or dwellinghouse, standing separate from or without it, at a small distance — with barn, stable, and dairy-house given as canonical examples. Burrill explicitly flags that the word "has been made the subject of considerable construction in the law of burglary," directing the researcher to Crabb's Real Property, Russell on Crimes, and Wharton's American Criminal Law. This is the most instructive of the historical entries and the most useful starting point for tracing the doctrine.
The historical sources collectively agree on the core concept: an outhouse is a functionally associated, physically separate, ancillary structure. Where they diverge is in how to handle structures at the margins — structures more distant from the dwelling, or serving purposes less immediately essential to daily domestic life. Neither Black's edition resolves those edge cases, and the reliance in Burrill on treatise cross-references suggests the dictionaries themselves were deferring to case law and secondary authority for the harder questions.
Jurisdictional Note
The legal significance of "outhouse" in burglary doctrine varies by jurisdiction based on how individual states codified the common law offense. Some 19th-century statutes explicitly extended burglary to outhouses and enumerated qualifying structures; others left the term undefined and relied on common law construction. Modern statutes have largely replaced the outhouse analysis with curtilage doctrine or explicit enumeration of protected structures.
