Commercial property insurance costs nearly doubled over the past decade, rising from $1,558 per building per month in 2013 to $2,726 per building per month in 2023, according to Deloitte Insights. At the same time, extreme weather events are increasing in both frequency and severity.
These rising costs reflect a broader shift in how the building industry evaluates and manages risk. Building codes have traditionally focused on keeping people safe during a disaster. But keeping people safe and keeping a building operational are two very different things. A building can meet every code requirement and still take months to reopen.
That gap between surviving a disruptive event and recovering quickly from it is what building resilience addresses. For building owners, property managers, homeowners’ association (HOA) boards, and facilities directors, understanding commercial building resilience may help support long-term asset value protection, operating cost control, and tenant satisfaction.
Key takeaways: why commercial building resilience matters for property portfolios
Rising insurance costs and increasing weather severity are changing how commercial properties are assessed and maintained. Understanding resilience may help building owners and property managers make more informed decisions about protecting long-term asset value.
Why it matters
- Business interruption costs can sometimes exceed repair costs, making lost operations a significant financial exposure
- Buildings designed to modern building codes may return up to $11 in avoided losses for every $1 invested, according to research from the National Institute of Building Sciences. Documented building improvements may help during insurance renewal discussions, though premium relief is not guaranteed
How resilience applies to property management
- Resilience planning evaluates all major systems: structural, envelope, mechanical, electrical, and life safety
- Proactive assessments may help identify vulnerabilities before they become emergency repairs
- Defining recovery targets in advance can help inform capital planning and budget priorities

What is commercial building resilience?
Commercial building resilience is the ability of a building to keep operating through a disruptive event and return to full functionality quickly afterward. It covers how the building is designed, how it is maintained, and how prepared the ownership and management teams are to respond when something goes wrong.
Most building codes focus on life safety: keeping occupants protected during a hurricane, earthquake, or fire. Resilience goes a step further by asking what happens the day after. Are tenants able to return? Are business operations able to resume? How long before the building is fully functional again?
The National Institute of Standards and Technology (NIST) defines community resilience as the ability to prepare for anticipated hazards, adapt to changing conditions, and withstand and recover rapidly from disruptions.
Four principles of resilient design
Resilience planning is built around four connected ideas:
- Anticipate: Identify what hazards could affect the building based on its location, type, and the systems associated with its operation
- Absorb: Design building systems intended to reduce initial impact and help limit damage that may spread to other parts of the building
- Adapt: Build in the ability to adjust when conditions change, such as running essential operations on backup power
- Recover: Get the building back to full operation as quickly as possible to minimize lost revenue and tenant disruption
A building that anticipates flooding risk, absorbs initial water exposure without major damage, adapts by keeping essential equipment running, and recovers through pre-planned repairs is generally better positioned than one that simply meets minimum code requirements.
How building resilience differs from traditional building design
Traditional building codes ask, “Will this building keep people safe during a storm?” Resilience planning asks, “How quickly might this building get back to business after a storm?”
A building can pass every inspection and still leave tenants displaced for months if the heating system floods, the electrical equipment fails, or water gets behind the walls and takes weeks to dry out. Code compliance is designed to protect people. Resilience is intended to protect the building’s ability to function, and with it, the owner’s revenue, tenant relationships, and long-term property value.
Why this matters to commercial property owners
The financial cost of poor building resilience can often be measured, and most of it shows up outside the repair bill. Lost rent, displaced tenants, supply chain delays for replacement parts, and the time it takes to get insurance claims approved and contractors scheduled may all stretch recovery far beyond what the physical damage alone would suggest.
The real cost: lost operations, not just repairs
When a commercial building is damaged, lost business operations often cost more than fixing the building itself. This is called business interruption loss.
A medical office that loses power is generally unable to see patients. A refrigerated warehouse that loses cooling may lose its entire inventory. An office building that loses heating in winter may become uninhabitable. In each case, the building might be structurally sound, but it may not be able to function.
Recovery is also affected by factors outside the building. A property can survive a storm with minimal damage and still remain closed because a nearby power substation is down or local roads are impassable.
Insurance and property value pressure
Insurance premiums are one of the most visible signs that resilience risk is increasing. Properties in areas with higher exposure to storms, flooding, or wildfire may also see declining values, though the impact varies by market and property condition.
Documented building improvements, such as upgraded roofing, flood protection measures, or backup power systems, may sometimes help during policy renewal discussions. Premium relief is not guaranteed, but insurers increasingly factor these measures into their risk assessments.
Core components of a resilient building
A storm does not damage one system in isolation; problems in one area often cascade into others. Water that enters through a damaged roof may flood electrical rooms, disable fire alarms, and soak wall insulation, turning a roof repair into a months-long restoration project.
Structural systems
The structural frame is the skeleton of the building: the foundation, columns, beams, and load-bearing walls. A resilient structure is typically designed so that forces travel through continuous load paths from roof to foundation, and connections between structural elements are designed to help resist wind and seismic forces.
A building can meet structural safety codes and still suffer damage that delays reopening. Ceiling systems may fall or equipment mounted inside the building may break loose, even though the structure itself remains standing.
Building envelope
The building envelope is the exterior enclosure system: the roof, exterior walls, windows, doors, and waterproofing. It generally serves as the primary barrier against wind, rain, and temperature extremes.
Envelope failures are among the most frequent and costly sources of damage in commercial buildings. A small gap at a roof edge, an aging sealant joint around a window, or a deteriorating flashing detail (the metal pieces that direct water away from joints) may allow wind-driven rain into hidden spaces inside walls, elevator shafts, and electrical rooms.
Mechanical and electrical systems
This category covers heating, ventilation, and air conditioning (HVAC); plumbing; electrical distribution; and emergency generators. These systems are often among the most vulnerable because they rely on equipment that is expensive to replace and can take weeks or months to procure.
Mechanical, electrical, and plumbing (MEP) assessments typically evaluate equipment condition, capacity, and remaining useful life as part of overall building system performance. Resilience adds a second layer by identifying single points of failure: a main electrical room in a basement that could flood, a backup generator that only covers a fraction of the building’s needs, or a cooling system that may not keep up during extended heat waves.
Life safety systems
Life safety systems are designed to protect building occupants during emergencies: fire alarms, sprinkler systems, emergency lighting, and exit pathways. These systems typically require regular inspection and maintenance to remain functional.
Life safety performance is also closely tied to how quickly a building may be able to reopen. Impaired fire alarms, damaged sprinkler piping, or broken emergency lighting may delay or prevent authorities from allowing tenants back in.
Techniques for improving building resilience
Improving resilience typically follows a straightforward sequence: understand the building’s current condition, identify vulnerabilities, prioritize improvements based on risk and budget, and maintain those improvements over time.
Assessment as a starting point
A structured property condition assessment typically provides baseline information on all major building systems. These evaluations generally follow American Society for Testing and Materials (ASTM) E2018 standards and produce cost estimates organized by urgency: what needs attention now, what should be addressed in the next few years, and what can be planned over a longer horizon.
A resilience-focused assessment adds hazard-specific questions. In hurricane-prone areas, that might mean evaluating whether roof edges are designed to resist uplift forces. In flood zones, it might mean identifying where water could enter at ground-level doors and loading docks.
Targeted retrofits and upgrades
Once vulnerable areas are identified, building owners and facilities teams can evaluate which improvements offer the most protection relative to cost and disruption. Common resilience improvements include:
- Envelope hardening: Reinforcing roof edges, improving flashing at joints, or adding impact-resistant window protection to help reduce water and wind damage
- Equipment protection: Moving essential mechanical and electrical equipment out of flood-prone areas or improving how equipment is anchored
- Power continuity: Expanding backup generator coverage to help maintain essential building functions
- Nonstructural bracing: Securing pipes, ceiling grids, and interior equipment that may be damaged even when the structure performs as intended
These improvements generally work best when planned together across systems. Addressing the roof without considering drainage or reinforcing walls without reviewing connections to the foundation can leave gaps that reduce the overall benefit of the work.
Ongoing maintenance and preparedness
Resilience is not a one-time project. Building conditions change over time due to weather exposure, material aging, and shifts in how a property is used. Ongoing programs often include:
- Documented inspection and maintenance schedules for the roof, drainage, mechanical and electrical equipment, and life safety systems
- Updated emergency procedures and vendor contact lists for priority repairs
- Advance planning for replacement parts with long lead times
When these programs are in place, recovery tends to be faster because key decisions and purchases are made in advance. Maintenance records may also help inform conversations with insurance underwriters during policy renewal.
Why building resilience should be a priority
Commercial building resilience helps connect property performance with long-term financial outcomes. For building owners, property managers, and facilities directors, the potential implications include lower long-term operating costs, more stable insurance terms, stronger tenant retention, and protected asset values.
As building codes evolve to address not just safety but also how quickly buildings can recover, and as insurers continue adjusting pricing based on documented building improvements, the gap between well-prepared properties and those that defer resilience planning is likely to widen.

Frequently asked questions
How should building owners prioritize resilience upgrades across a portfolio with a limited capital budget?
Owners typically start by mapping which hazards affect each property, then identifying which buildings generate the most revenue or face the highest risk of extended downtime. Focusing on improvements that address shared vulnerabilities across multiple properties may help stretch limited budgets further.
What specific documentation do insurance underwriters look for when evaluating resilience mitigation measures during policy renewal?
Underwriters often review engineering reports, maintenance records, and related documentation to assess how well a building is protected. Including dated photographs, drawings showing protective measures, and records confirming completed work may help renewal discussions reflect actual building conditions.
How long does recovery typically take for a commercial building after a major weather event, and what causes the longest delays?
Recovery timelines vary widely based on damage severity and how quickly replacement parts can be obtained, but restoration can range from weeks to months. Mechanical and electrical equipment replacement frequently contributes to the longest delays because specialized components often require extended manufacturing, testing, and installation time.
