Renovation Risk: Why Water Damage Is the Biggest Threat to Adaptive Reuse Projects
One of today’s top trends in commercial construction traces its name—and its early popularity—back to the 1970s. Adaptive reuse, also known as building conversions or retrofits, is transforming vacant offices, shuttered factories, and aging commercial properties into revitalized spaces more in line with modern needs: apartments, community centers, entertainment hubs, and more.
While adaptive reuse has steadily grown over the past 50 years, recent factors like the COVID-19 pandemic, changing urban landscapes, high interest rates, and remote work culture have accelerated the pace of redevelopment. General contractors, building owners, and developers are taking a fresh look at existing structures, weighing their potential for reinvention, and the financial incentives, sustainable benefits, and community improvements that can follow. According to forecasts from ConstructConnect, U.S. commercial renovation spending could rise nearly 70% in the next several years, reaching $500 billion by 2030.
But as promising as these projects can be, they’re not without risk. And no threat disrupts adaptive reuse projects faster, or more expensively, than water damage. In this article, we’ll explore the unique challenges of conversions and how proactive protection strategies can help keep them on track.
What Makes Conversions Different
Adaptive reuse projects are driven by a range of factors. Financially, renovating may be more cost-effective than new construction after weighing purchase prices, labor, materials, and permitting.
Many of these properties also carry historic or architectural significance. Renovating them preserves community heritage while meeting modern demand. At the same time, the revitalization can help boost neighborhood property values and stabilize tax bases.
As many retrofits are on buildings 50+ years old, building code changes mean that properties in certain areas may require updates to satisfy more recent requirements to protect against earthquakes, hurricanes, wildfires, or high winds. This aids in the real estate market and urban renewal, while creating job opportunities in construction and renovation to further stimulate local economies. As an added benefit, conversions can incorporate green initiatives to reduce environmental impact and carbon footprint.
Nonetheless, conversions are inherently complex. These projects often require comprehensive updates to electrical, plumbing, HVAC, windows, insulation, and accessibility, all while managing the potential for budget overruns and scheduling challenges, as well as meeting stakeholder expectations. And in the midst of it all, water damage remains one of the most disruptive and costly hazards, capable of derailing even the most carefully planned job.
Where Water Risk Starts
Water damage risks for adaptive reuse projects can fall into one of three categories: existing building issues, renovation-caused risks, and complications from partial occupancy.
Existing building issues
Many older buildings harbor water damage risks that may have developed long before construction begins. Over the years, pipe leaks, condensation, and water intrusion can weaken foundations, crack structures, and lead to hidden mold growth. Weathering erodes masonry and seals, allowing moisture to penetrate. Poor insulation and repeated freeze-thaw cycles strain pipes and systems. Even roofs with degraded materials or failed vent seals can leak undetected.
Exposing the building’s framework often reveals the true extent of this damage—and depending on the size and design, tracking leaks through wall cavities, ceilings, and vertical shafts can be challenging, especially in high-rises.
Mechanical, electrical, and plumbing (MEP) systems frequently show decades of deferred maintenance or inadequate reports. Galvanized or cast-iron pipes may be corroded and brittle. Even newer buildings face risks from clogs, chemical erosion, or weakened fittings. When a dormant system is recharged after months or years, leaks can appear quickly and without warning.
Renovation-caused risks
The renovation process introduces its own hazards. Inaccurate or missing building plans often mean plumbing, water lines, or risers appear in unexpected places. Subcontractors may inadvertently damage active lines during demolition or drilling. And when structural elements like walls, foundations, or roofs were previously modified, water lines may have been rerouted, creating a logistical headache for current crews.
Opening enclosures for ventilation, light, or expanded egress also leaves buildings vulnerable to exterior water intrusion. Green roofs and landscaped areas, while environmentally beneficial, increase complexity by adding water management systems that must drain effectively.
Keeping water systems active during phased construction—particularly in partially occupied buildings—amplifies risk. Whether it’s a light retrofit or a full-scale conversion, increased plumbing, HVAC systems, fire suppression, and amenities like kitchens, spas, or gyms multiply the number of potential leak points.
And as in any job, less experienced or distracted subcontractors can cause avoidable disasters, whether by improperly connecting a fixture or failing to unplug a drain before testing water flow.
Partial-occupancy complications
In adaptive reuse projects, parts of a building may remain occupied while other sections undergo renovation. This increases both the potential for water damage and the difficulty of early detection. A tenant’s water use may exacerbate unknown leaks behind walls or above ceilings. In addition, restricted site access can prevent identifying issues and reporting them on a timely basis.
Water intrusion incidents occurring over nights, weekends, or holidays can go unnoticed for hours or days, rapidly compounding the extent and expense of the damage. Whereas water leak caught within a short period of time can be mopped up with very minimal to no damage, unchecked water seepage can devastate flooring, exposed drywall, and equipment with expensive electronic components.
The True Impact Of Water Damage
Water-related losses do not just affect the job site. They ripple outward in multiple costly, reputation-damaging ways:
- Tenant or Neighbor Disputes: Damage or disruptions from water leaks can trigger insurance claims from neighbors and tenants, while delays fuel frustration and conflict. Occupancy dates can also be impacted, resulting in contract issues and lost income.
- Timeline Collapses: Delays impact permits, inspections, and occupancy certificates. Some projects operate on strict sequences where delays to one element, like finding out the roof has water damage prior to a heavy air conditioning unit being installed, cause cascading schedule issues.
- Labor Shortages: Specialty subcontractors like mold remediation crews, historical restoration experts, or glass artisans may be booked months out. Damage-related delays mean losing access to those trades or requiring them for longer periods than budgeted.
- Budget Implosion: Even seemingly minor water incidents can stack up. A single day of drying, demolition, and rebuild can add 0.5% to 1% to the total project cost. Since renovations start with a finished structure versus ground-up construction, there’s more at stake from day one of the project, especially if original millwork, tiles or finishes have been preserved.
- Reputation Damage: Large, preventable losses reflect poorly on contractors and developers. A serious incident can jeopardize future bids, delay financing approvals, and damage client trust.
How IoT Keeps Projects Safe
Given the severity and variety of water-related risks, real-time monitoring has become essential, and that’s where IoT (Internet of Things) technology transforms project risk management on adaptive reuse sites.
IoT systems offer value immediately after they’re deployed, providing early detection of conditions that can lead to future losses. From demolition through final inspections, these devices continuously track environmental conditions and system performance, sending instant alerts when thresholds are exceeded.
“There’s a strong reason for deployment of IoT solutions on renovation projects. We've seen far more water damage claims on renovation projects than we have on new construction projects, and the claims data from various insurance companies validate that as well,” said Bret Bush, EVP and Co-Founder at Insight Risk.
Today’s market offers a range of specialized devices, each engineered to address specific risks during adaptive reuse construction:
- Water Detection Sensors: Compact and highly sensitive, these devices can be strategically placed in stairwells, risers, mechanical rooms, or beneath HVAC equipment—wherever water might accumulate. Their portability makes them ideal for active construction sites, moving as work areas shift or as enclosures are completed. Extension cables can expand sensor coverage, creating comprehensive monitoring networks throughout construction zones.
- Leak Detection Cables and Mats: These specialized variations of water detection sensors provide continuous monitoring along perimeters or across large areas. Capable of detecting as little as a few drops of water, they deliver comprehensive coverage where point sensors alone would leave gaps. While invaluable during construction, these systems are designed for permanent use, easily integrated into the finished building’s management systems for ongoing protection.
- Water Flow Meters: Clamped onto main water lines, these devices measure water usage in real time, identifying abnormal flow rates or water use during off-hours which can be key indicators of leaks or unauthorized consumption. During renovations, retrofitting and cutting pipes may not be an option, so the noninvasive nature removes the risks of cutting large water mains entirely. Advanced systems can sub-meter individual risers or equipment, offering granular visibility into water use trends and enabling predictive maintenance strategies.
- Remote Water Shutoff Valves: Critical for adaptive reuse projects where portions of the property remain occupied, these remotely controlled valves allow for manual, scheduled, or automated shutoffs within minutes of detection. This capability minimizes the spread of water during an incident and can isolate problem areas without disrupting the entire site, protecting both active construction zones and tenant-occupied spaces. If rework is being performed on the plumbing, installing shutoff valves can bring value to both the construction and occupancy phases of the building.
- Humidity Sensors: Elevated relative humidity is often the earliest sign of an issue, signaling hidden leaks, elevated moisture from open enclosures, or drying failures following water events. These sensors are especially valuable during envelope removal, window replacement, or mechanical upgrades, providing a critical safeguard for materials like millwork, drywall, or high-finish surfaces sensitive to prolonged moisture exposure.
- Temperature Sensors: Temperature sensors are key to detecting freeze risks in both exposed and enclosed areas. They’re especially useful in vacant or partially heated sections of a building, helping identify spots where pipes, sprinkler lines, or mechanical systems may be vulnerable to low temperatures. Alerts can be triggered when ambient conditions drop near freezing, giving teams time to proactively heat zones or drain vulnerable lines before damage occurs. These sensors also help verify that HVAC systems are maintaining stable temps during transitions between construction phases and occupancy.
Examples of Technology
Matt Joyal, Vice President of Technology at Insight Risk, summarized the benefits of using these devices in tandem: “Modern IoT solutions aren’t just jobsite tools; they’re part of a flexible risk management toolkit. Every construction project presents its own set of vulnerabilities, whether it’s aging infrastructure, partial occupancy, sensitive finishes, or unpredictable weather exposure. The most effective IoT deployments begin by understanding these conditions, then selecting the best-fitting sensor for each unique risk. This targeted approach reduces unnecessary hardware, keeps costs manageable, and ensures that monitoring is both efficient and impactful.
“There’s no one-size-fits-all solution, just smart tools applied with precision,” he added. “When thoughtfully deployed, these systems not only protect what’s under construction, but also lay the foundation for smarter, more resilient building operations long after the project is complete.”
A major advantage of modern IoT devices is their flexibility. Most are lightweight, unobtrusive, and easy to reposition as construction phases progress. Many are designed to affix with magnets, adhesive strips, or hook-and-loop fasteners, ideal for non-invasive temporary deployments within historic or specialty spaces. Integrated dashboards display sensor locations over project drawings, enabling site managers to track devices in real time and adjust placements as work areas expand or contract.
IoT systems also scale efficiently across multi-project portfolios. For general contractors managing several adaptive reuse jobs simultaneously, centralized monitoring dashboards provide portfolio-wide oversight with site-specific data, helping teams identify systemic trends, prioritize resources, and benchmark performance across sites.
And while most devices start as temporary job site tools, many can transition into the finished building’s infrastructure. As part of the renovation and retrofit planning process, it’s critical to engage owners early about long-term monitoring strategies:
- What conditions do they want to track post-occupancy: for insurance purposes, operational oversight, or tenant safety?
- Which Building Management System (BMS) will be installed, and what IoT technologies can integrate seamlessly into it?
- Which assets or spaces warrant permanent protection (mechanical rooms, historical elements, tenant amenities, green roofs)?
Specific technologies like automated water shutoff valves or smart leak detection cables can be commissioned during construction and remain operational after turnover. This extends risk mitigation beyond substantial completion and adds long-term operational value, offering the owner data-driven insights into the building’s infrastructure and ongoing protection from preventable water damage.
Proactive Insurance Innovation
Smart prevention strategies, especially those using IoT monitoring systems, deliver dual benefits: preventing costly water damage incidents and positioning contractors and owners for more favorable insurance terms.
Insurance carriers increasingly recognize the value of real-time monitoring as proof of a proactive risk management approach. Projects with active IoT programs typically demonstrate reduced claim frequency and severity, and insurers may translate that into reduced premiums, lower deductibles, or preferential access to coverage, a significant advantage given how difficult it can be to secure builder’s risk policies for adaptive reuse projects involving major structural alterations.
Underwriters reviewing these projects often flag elevated risk from water loss due to aging systems, uncertain infrastructure, and complex site conditions. Having active IoT monitoring during construction, paired with documentation of water event responses and maintenance data, strengthens a submission by showing measurable loss control in place.
Moreover, integrating permanent IoT infrastructure positions the completed building for better insurability under property policies. Post-renovation facilities that retain monitoring systems for water, humidity, and temperature anomalies can often qualify for enhanced endorsements or reduced water-damage-related deductibles, especially in high-risk geographies or for mixed-use properties.
It’s also important to recognize that standard risk management practices like night patrols or visual site inspections, while valuable, are limited by human availability and visibility. IoT-enabled monitoring instantly scales protection capabilities, providing 24/7 coverage in areas that can’t be consistently patrolled such as attics, basements, elevator shafts , or locked tenant spaces. Immediate alerts upon detection enable faster interventions, minimizing loss size and business disruption.
