Encroachments That Derail Property Deals: What an ALTA/NSPS Survey Can Uncover Before They Become Expensive Fixes

Encroachments remain one of the most underestimated risks in commercial real estate transactions. They often stay hidden for years, only surfacing when a property is under contract, and due diligence is already in motion. This is why buyers, lenders, and attorneys consistently depend on fast and accurate ALTA surveys to identify boundary conflicts before they disrupt timelines or create unexpected costs.
At their core, encroachments represent a disconnect between legal property boundaries and real world conditions. A structure, improvement, or use extends beyond its permitted limits and into space it does not legally control. While this may sound abstract, the implications are very tangible. A single overlooked encroachment can halt financing, reduce insurability, or force costly corrections that reshape the economics of a deal.
Understanding How Encroachments Actually Develop
Encroachments are rarely the result of deliberate wrongdoing. In many cases, they form gradually as properties evolve. Boundaries established decades ago may no longer be evident on the ground. New owners inherit improvements without realizing they cross a line. Over time, these conditions become normalized until a formal survey brings them into focus.
This is especially true in properties that have undergone multiple renovations or changes in use. Parking areas may expand incrementally. Fences get replaced without precise measurement. Even building additions can be constructed based on assumptions rather than verified boundary data. Without professional documentation, these errors accumulate quietly.
Why Encroachments Carry Outsized Risk
Encroachments are not just technical issues. They directly affect ownership rights and control. A property owner may believe they have full use of a space, only to learn that part of it legally belongs to someone else. This can restrict how the property is operated or improved in the future.
From a transactional standpoint, encroachments introduce uncertainty. Lenders rely on surveys to confirm that collateral is secure and unencumbered. If a survey reveals unresolved boundary conflicts, loan approval may be delayed or denied. Title insurers may also limit coverage, leaving buyers exposed to future claims.
Common Encroachments Revealed Through ALTA/NSPS Surveys
ALTA/NSPS surveys routinely uncover patterns that visual inspections miss. Buildings that slightly cross property lines are a frequent finding. So are fences or walls that were installed for convenience rather than accuracy. Driveways and parking areas often extend beyond legal limits, especially when properties share access points.
Utilities also present recurring challenges. Light poles, transformers, drainage structures, and underground easements may intrude into neighboring parcels. These features may appear harmless, but they still represent legal conflicts that require resolution.
How ALTA/NSPS Surveys Bring Clarity
An ALTA/NSPS survey does more than measure land. It overlays recorded boundary data with existing improvements to create a precise representation of current conditions. Surveyors compare what is built with what is legally described, highlighting discrepancies that may not be obvious otherwise.
This process transforms abstract legal descriptions into clear visual evidence. Encroachments are quantified, documented, and reported in a manner that allows attorneys, lenders, and insurers to evaluate them efficiently. The result is not just information, but actionable clarity.

The Financial Impact of Late Discovery
Timing matters. Discovering encroachments late in a transaction often results in costly consequences. Structures may need to be modified or removed. In some cases, buyers must negotiate easements or boundary agreements under pressure, reducing their leverage.
These fixes rarely come cheaply. Legal fees, construction costs, and delays can quickly erode deal value. In extreme situations, unresolved encroachments force buyers to abandon transactions altogether after significant time and expense have already been invested.
Why Visual Inspections Are Not Enough
Many buyers assume that walking through a property provides sufficient insight. Unfortunately, visual cues are unreliable. Fences, curbs, and pavement do not consistently align with legal boundaries. Longstanding use can create a false sense of certainty that collapses under scrutiny.
Only a professional survey can establish where ownership actually begins and ends. This is why fast and accurate ALTA surveys remain a cornerstone of adequate due diligence rather than a formality.
Strategic Value of Early Encroachment Detection
Identifying encroachments early shifts the balance of power. Buyers can renegotiate pricing, require corrective action, or adjust plans before becoming fully committed. Sellers benefit as well, since clear documentation supports more transparent negotiations and reduces the risk of last-minute surprises.
Local expertise further strengthens this process. An alta survey Dallas, TX, for example, often reveals encroachments tied to older development patterns and evolving commercial uses. Familiarity with these conditions helps stakeholders interpret findings realistically and respond appropriately.
Encroachments and Long Term Planning
Beyond closing a deal, encroachments affect future flexibility. A minor boundary issue today can block expansion or redevelopment tomorrow. Planned additions may be impossible if they intrude into disputed space. Understanding these constraints early allows owners to plan within legal limits and protect long term value.
Final Perspective
Encroachments are not rare anomalies. They are common byproducts of how properties change over time. Left undiscovered, they can quietly undermine otherwise sound transactions. By relying on fast and accurate ALTA surveys, stakeholders gain the insight needed to address risks proactively, preserve deal momentum, and avoid costly fixes that surface too late.
