Somewhere in your organization's records there is a set of building drawings. They may be rolled up in a storage room, filed in a cabinet, or saved to a shared drive that three people know how to access. These drawings represent what your building looked like at some point in the past, and they are the documents your team relies on when decisions need to be made about the space.
The question most building owners never think to ask is whether those documents are actually accurate. In many cases, they are not. And that gap between what the records show and what the building actually contains creates a category of liability that compounds silently until something forces it into the open.
Where the Liability Lives
Inaccurate or outdated building documentation creates exposure across several areas that building owners may not associate with their drawings.
● Lease disputes. Commercial leases are built on square footage figures. If those figures were never professionally verified, or if they were measured under an outdated standard, tenants who commission their own measurements may discover discrepancies. The resulting disputes can lead to rent adjustments, back-payments, or legal action.
● Insurance gaps. Property insurance coverage is typically tied to building area and replacement cost estimates. If the square footage on file is understated, the building may be underinsured. If the building's actual layout differs from what was documented, claims related to specific areas or systems may be challenged.
● Code compliance failures. Building codes evolve, and compliance reviews reference the building's documented conditions. When those records do not reflect the current state of the space, code violations that should have been identified during planning go unnoticed until an inspection or incident reveals them.
● Accessibility exposure. ADA compliance assessments depend on accurate spatial data. Door widths, corridor clearances, restroom dimensions, and ramp slopes must be verified against the actual building, not against drawings that may predate multiple renovations.
● Due diligence failures. Property transactions, refinancing, and portfolio assessments all reference building documentation. Buyers, lenders, and appraisers who rely on inaccurate records may make decisions based on a building that does not match what they are acquiring or financing.
Why the Problem Gets Worse Over Time
Buildings change. Tenants modify spaces. Systems get upgraded, rerouted, or replaced. Walls move. Ceilings get lowered. Equipment gets added. Each change is small enough that no one commissions updated documentation, but over years and decades, the cumulative drift between the records and the actual building becomes significant.
The original drawings may have been accurate when they were produced. But a building that has been occupied and modified for twenty or thirty years bears little resemblance to its original plans. The records in the filing cabinet are not wrong because someone made an error. They are wrong because the building moved on, and the documentation did not.
What Accurate Documentation Changes
Professional as built services replace assumptions with verified, measured records of the building as it actually exists. The resulting documentation provides a defensible baseline that supports:
● Lease negotiations backed by BOMA-compliant square footage calculations
● Insurance coverage that reflects the building's true size and condition
● Code and accessibility reviews based on actual dimensions, not estimated ones
● Due diligence packages that give buyers, lenders, and appraisers confidence in the data
● Renovation and space planning projects that start from verified existing conditions
The cost of professional documentation is a fraction of what a single lease dispute, insurance claim denial, or code violation can produce. The difference is that documentation is a planned investment, while the consequences of inaccurate records arrive without warning.
The Risk of Doing Nothing
The liability in the filing cabinet does not announce itself. It waits until a tenant challenges their square footage, until a claim is filed and the insurer questions the documentation, until a code inspector finds conditions that the drawings failed to reflect, or until a buyer discovers discrepancies during due diligence. At that point, the cost of resolving the problem far exceeds what it would have cost to prevent it.
Every building owner should be able to answer a simple question: when was the last time your building's documentation was professionally verified against the actual space?
When the records in the filing cabinet can no longer be trusted, Architectural Resource Consultants (ARC) replaces them with precise, field-verified as-built services and building documentation that holds up under scrutiny. ARC provides nationwide as-built services from licensed architects and LOA-certified technicians.
