A visitor to a multi-tenant office building slips on a wet floor in the common-area corridor. The property management company cleans that corridor. A commercial tenant's employee also wet-mopped it an hour earlier. The building owner's maintenance contract required inspections every two hours. None were logged since morning. This is not a clean single-defendant case, and the fault allocation among multiple parties with overlapping duties over the same physical space is what PI attorneys need to work out before demand, not at deposition.
The Baseline Duty Framework
Property owners owe a duty to invitees, persons who enter the premises for a purpose that benefits the property owner, to inspect for and correct, or warn of, foreseeable dangerous conditions. That duty does not disappear when the owner leases portions of the building to commercial tenants. The owner retains a non-delegable duty to maintain common areas, which typically include lobbies, elevators, stairwells, hallways, parking structures, and shared restrooms, in a reasonably safe condition.
The commercial tenant's duty over the leased space depends on the lease terms and on who exercised day-to-day control over the specific area where the fall occurred. Under most commercial leases, the tenant takes responsibility for the interior of the leased suite. Where the fall occurs in the leased suite itself, the tenant is the primary responsible party, and the building owner may have no liability if the hazard was entirely within the tenant's zone of control and the owner had no notice of it.
The harder cases are the boundary zones: the space immediately outside a tenant's suite door, a shared entryway between two tenant spaces, a loading dock used by multiple tenants, or a conference center lobby that the property manager and tenant both claim the other maintains.
Notice in the Multi-Party Context
Constructive notice analysis in an office building requires building-specific documentation. Unlike a grocery store where a single entity controls the entire selling floor, an office building may have dozens of tenants, a property management company, and a separate janitorial contractor, all of whom keep separate logs of when areas were inspected and cleaned.
Request all of the following in early discovery: the property manager's maintenance log for the area of the fall, all janitorial contractor records including cleaning schedules and sign-off sheets, any tenant maintenance requests submitted to building management in the 90 days before the fall, the lease provisions governing each party's maintenance obligations, and any inspection records kept by the specific tenant whose suite adjoins the fall location.
Compare those records against the time of the fall. A maintenance log showing no inspection for six hours before a fall in a corridor rated for heavy foot traffic tells a constructive notice story. An absence of any log, where the lease required inspections, tells an even stronger one, because courts have held that a failure to conduct required inspections supports an inference that the hazard existed long enough to be discovered had reasonable care been exercised.
The Commercial Lease Indemnification Clause
Commercial leases routinely include indemnification clauses under which the tenant agrees to defend and hold harmless the property owner from claims arising out of the tenant's use of the premises. Defense counsel for the building owner will invoke this clause quickly after a lawsuit is filed, seeking contractual indemnity from the tenant and potentially tendering the defense to the tenant's insurer.
From a plaintiff's perspective, the indemnification clause is mostly a background issue: it determines how the defendants apportion liability among themselves, but it does not insulate either party from the plaintiff's direct negligence claim. Both the property owner and the tenant can be named as defendants, both can be found liable in proportion to their respective control and notice, and the indemnification clause operates only in the subsequent cross-claims they file against each other.
What the indemnification clause does affect is settlement strategy. If the building owner believes the tenant is contractually required to indemnify, the owner will resist settling at the plaintiff's demand because it expects the tenant to fund the resolution. If the tenant believes the hazard was in a common area and outside the indemnification clause's scope, the tenant will resist the tender. These cross-disputes often delay settlement, and the plaintiff who understands the lease structure going in can anticipate the dynamic and structure demands accordingly.
The Open-and-Obvious Defense in Office Buildings
Open-and-obvious arguments are more common in office building cases than in retail settings because office visitors are often presumed to be sophisticated adults traversing familiar hallways. Courts have held that a well-lit lobby threshold, a known step-down at an entryway, or a distinctive flooring transition is open and obvious and does not create a duty to warn.
The counter to this defense in office building falls focuses on attention distraction. Visitors who are carrying bags, reviewing phones, or responding to greetings from reception staff when a fall occurs are arguably not in a position to appreciate a hazard even if it is technically visible. The mode-of-operation doctrine, originally developed in grocery stores, has been applied in office building contexts where the defendant's own operational design (a reception desk positioned to distract visitors toward it while they approach a step-down) contributed to the fall.
Document the physical layout from day one. Photographs and video of the fall area taken before any remediation capture the geometry, the lighting levels, the surface transitions, and the sightlines. If the building has a security or lobby camera, send a spoliation demand to both the property manager and the tenant simultaneously on the day of engagement. Buildings with commercial tenants often store surveillance footage on vendor systems not under the building owner's direct control, and the 30-day loop used by most commercial surveillance vendors means delay in sending the demand costs the footage.
