Definition
A standard of physical condition imposed on property — most commonly by lease covenant, deed restriction, or statute — requiring that the subject premises, structure, or fixture be maintained in a state of sound working order and structural integrity, free from material defects or deterioration. The term does not demand perfection or improvement beyond the condition at the outset of the obligation; it requires maintenance at a level that is functional, safe, and reasonably preserved against ordinary wear.
The phrase appears most frequently in two contexts:
(1) Lease covenants. A tenant's obligation to maintain and return premises in good repair is among the most litigated lease provisions in landlord-tenant law. The covenant requires affirmative upkeep during the tenancy and, at expiration, surrender of the premises in a condition reflecting that ongoing maintenance — subject to the important casualty exception described below.
(2) Statutory and regulatory maintenance obligations. Landlords, property owners, municipalities, and utilities are sometimes required by statute, code, or ordinance to keep structures, equipment, or infrastructure in good repair as a condition of lawful operation or as a standard against which liability is measured.
Common Language
Modern common usage (Wiktionary): "Good repair" in everyday English means a state of being well-maintained, undamaged, and functional. The phrase carries no technical content in ordinary use.
Historical common usage (Webster's 1913): Webster's 1913 does not appear to define "good repair" as a discrete entry, treating "repair" generally as the act of restoring something to a sound condition after damage or deterioration.
The legal gap is specific and consequential: in ordinary language, "good repair" describes a condition — something either is or isn't in good repair. In law, the phrase operates as a covenant term whose scope is defined by the instrument creating it, the condition of the premises at the time the obligation attached, and judicially developed rules about what events (such as fire or casualty) discharge the obligation entirely. A lay understanding of the phrase does not prepare a researcher for the fault-based limits and condition-at-inception rules that courts impose.
Common Confusion
Good repair covenants are frequently read as absolute obligations, but courts consistently hold otherwise. The obligation does not require a tenant or obligor to restore the property to better-than-original condition, nor does it require rebuilding or major structural restoration following destruction or substantial damage caused by casualty without the obligor's fault. Conflating a maintenance covenant with an insurance or restoration obligation is a persistent error in lease drafting analysis and dispute resolution. The distinction matters: a tenant who lets a furnace degrade through neglect has breached; a tenant whose leased building burns down has not.
Why It Matters in Research
The central research trap with "good repair" is treating it as a self-defining standard when it is not. Courts have spent over a century establishing what the phrase does and does not require, and the answers vary by instrument, jurisdiction, and context.
The casualty exception is the most important doctrine to locate. As Bouvier captures from a Kentucky case, a covenant to leave premises in good repair does not obligate a tenant to rebuild or restore after destruction by fire or other casualty without fault. This rule — rooted in the principle that a covenant to repair does not become a covenant to rebuild — appears across common-law jurisdictions but is not universally codified. Researchers examining historical lease disputes must check whether the jurisdiction at issue had adopted this rule at the time of the dispute, because some older courts took a stricter view.
Condition at inception matters. Courts frequently ask what condition the property was in when the obligation attached. A tenant cannot be held to a standard exceeding the state of the premises at lease commencement. Historical sources, including Bouvier, often do not spell this out because it was assumed; researchers working with older materials should not infer that silence on this point means the standard was absolute.
Statutory good repair obligations in landlord-tenant law emerged primarily in the twentieth century. Researchers working with pre-twentieth century materials will find the concept almost entirely in lease covenants and deed restrictions, not statute. Modern habitability codes and warranty of habitability doctrines exist alongside, but are analytically distinct from, contractual good repair covenants. Do not conflate them.
The phrase also appears in construction contracts, equipment leases, easement instruments, and municipal infrastructure law, each context generating its own body of interpretive rules. Cross-corpus searching on this term should account for the source document type.
Historical Dictionary Support
Bouvier's treatment is brief but practically useful. The single principle Bouvier records — that a lessee's covenant to repair or leave premises in good repair does not require restoration after casualty without fault — reflects settled common-law doctrine that courts had developed through the nineteenth century. The citation to a Kentucky appellate decision (103 Ky. 764) grounds Bouvier's statement in authority rather than abstraction.
What Bouvier does not address is also instructive. The entry contains no discussion of the affirmative maintenance obligation during the lease term, no treatment of what constitutes ordinary wear and tear (which is typically excluded from tenant repair obligations), and no mention of landlord-side repair covenants, which were less commonly litigated at the time. Researchers should treat Bouvier here as a single doctrinal data point rather than a complete account of the law.
No other source dictionaries in the Law Mind shelf provide a competing or supplementary definition for this term, so no comparative synthesis is possible from historical dictionaries alone.
Jurisdictional Note
The casualty exception to lease repair covenants is broadly recognized across common-law jurisdictions, but its precise contours vary. Some jurisdictions require express lease language to allocate casualty risk; others imply the exception as a matter of common law. Statutory modifications — including landlord-tenant codes that impose mandatory repair obligations on landlords — overlay and sometimes displace the common-law covenant framework in ways that differ significantly by state.
