After a severe storm, interior water staining appears at the base of a curtain wall, and the property manager cannot determine whether the building performed as designed or whether something changed. The same week, the insurance renewal arrives with a request for updated condition documentation and a premium that climbed again.
Both events point to the same question: how prepared is the building for the physical conditions it now faces?
Insurance costs for the four major commercial real estate asset classes grew more than 150% between 2017 and 2024, according to First Street research, and properties in high-risk markets now trade at measurable discounts.
Key takeaways: Preparing commercial property for physical climate hazards
For commercial properties, resilience planning connects physical hazard exposure with observed building conditions so capital plans address the systems most at risk.
Financial and regulatory drivers
- Insurance now consumes a materially larger share of average commercial property net operating income than it did in 2017, according to First Street research.
- Properties in high climate-risk markets may trade at measurable discounts relative to comparable assets in lower-risk regions.
- State and local disclosure requirements vary materially by jurisdiction and timeline.
The planning process
- A cross-functional team and clear performance goals anchor the effort.
- Hazard identification, system-level vulnerability evaluation, prioritization, implementation, and monitoring establish and sustain the plan.

Climate resilience planning for commercial property
Climate resilience planning is a voluntary, structured assessment of how a property prepares for and withstands physical hazards, then recovers from disruptions. These hazards include flood exposure and high winds, and some plans also consider extreme heat.
The National Institute of Standards and Technology (NIST) describes resilience as the ability to prepare for anticipated hazards, adapt to changing conditions, and withstand and recover rapidly from disruptions. That framing connects directly to building performance: a property that cannot recover quickly from a flood or wind event may experience extended business interruption, tenant loss, and deferred capital expenditure all at once.
ASTM E3429-24 establishes a Property Resilience Assessment (PRA) that identifies hazards, evaluates risk and recovery capacity, and identifies potential resilience measures. The Institute of Real Estate Management (IREM) links property resiliency to risk management and operational continuity rather than sustainability metrics, a distinction that matters when presenting the planning effort to ownership groups focused on asset protection.
Financial and operational drivers of resilience planning
Climate resilience planning matters because unaddressed physical risk can affect insurance costs and transaction pricing, while climate-related reporting requirements may add compliance obligations. Premium trends and transaction data can make parts of that risk measurable, while regulatory timelines may affect reporting obligations.
Rising insurance costs and coverage gaps
Insurance is among the most immediate financial pressures on commercial property. Its share of average commercial property net operating income has grown substantially since 2017, according to the First Street research cited earlier. Federal Reserve researchers have separately documented that multifamily property insurance costs rose more than 75 percent in real terms between 2019 and 2024, with rent increases offsetting only part of the added cost.
Sound commercial real estate risk management increasingly treats these premium trends as a planning input rather than a fixed cost. For properties in high-exposure regions, renewal cycles may bring requests for updated condition documentation alongside premium increases.
Asset value and investment protection
Transaction prices increasingly reflect physical climate risk. Commercial real estate assets in high climate-risk markets trade at a measurable discount compared to similar properties in lower-risk regions, with multifamily assets showing the steepest gap according to the same First Street research cited earlier. Academic research points to the same pattern: a March 2025 study in the Journal of Real Estate Finance and Economics found that higher disaster risk is associated with higher capitalization rates, meaning buyers pay less per dollar of property income, , reinforcing that investors are actively pricing physical risk into deal terms. Because buyers, lenders, and insurers now weigh this risk during underwriting, a building condition assessment may help document observed conditions and support that review.
Regulatory and disclosure requirements
For many commercial properties, the operative compliance environment for climate-related reporting may sit primarily at the state and local level. The Securities and Exchange Commission (SEC) proposed full rescission of its climate disclosure rules in May 2026 and is not currently enforcing them.
For California SB 261, the Ninth Circuit granted a preliminary injunction in November 2025, and the California Air Resources Board issued an advisory stating it will not enforce the January 1, 2026 deadline. Reporting remains voluntary for now. California’s companion emissions-reporting law, SB 253, is not affected by the injunction and remains on its own schedule, with initial greenhouse gas reports due August 10, 2026.Some local energy and emissions ordinances may remain enforceable on their own schedules. New York City Local Law 97 applies to buildings over 25,000 square feet and assesses civil penalties of up to $268 per metric ton over the applicable emissions limit.
The climate resilience planning process
A climate resilience plan may support development of a documented, prioritized set of measures that prepare a property for its specific hazard exposure. A typical plan begins with team formation and hazard identification, then moves through vulnerability evaluation, intervention prioritization, implementation, and monitoring.
Internal team formation and goal setting
A resilience effort begins with a cross-functional team and defined performance goals. The Building Owners and Managers Association (BOMA) Canada recommends bringing together asset managers, property managers, building operators, and risk managers to build an aligned, integrated approach. Goals should define the planning horizon and data basis for the assessment. The BOMA BEST Field Guide calls for a multi-decade planning horizon supported by climate projections from recognized data sources.
Climate hazard identification and site exposure
The second step identifies which natural hazards could affect a specific property and to what degree. The U.S. Climate Resilience Toolkit recommends building an exposure matrix that lists building assets in rows and potential hazards in columns, then evaluating each intersection. Entering an address into the American Society of Civil Engineers (ASCE) Hazard Tool returns the Federal Emergency Management Agency (FEMA) flood zone classification, base flood elevation, and design wind speed. The FEMA National Risk Index provides broader context across hazard types. A roof and drainage evaluation may extend the exposure review to observed surface-level conditions.
Building vulnerability assessment across systems
Vulnerability review examines how each building system would perform against the identified hazards and establishes a baseline of conditions and recovery capacity. ASTM E3429-24 structures this as a PRA covering occupant safety, potential damage, and functional recovery time. It complements the ASTM E2018 Property Condition Assessment many owners already use in due diligence, an approach covered in more depth in a broader property condition assessment overview. Where exposure and observed conditions intersect, a structural engineering assessment may help evaluate those conditions further.
Intervention prioritization and cost estimating
Prioritization can rank potential measures by economic efficiency so limited capital may address the highest-value risks first. The National Institute of Building Sciences (NIBS) reports that every dollar invested in resilience measures saves four to 11 dollars in avoided future losses, according to its 2025 research. For hurricane, wind, and flood protection specifically, the same research found each dollar spent reduced a building owner’s exposure to property loss and business disruption by an average of $105. An engineering due diligence checklist that spans structural, envelope, and mechanical systems can help ensure prioritization decisions reflect the full scope of a property’s vulnerabilities rather than a single system in isolation. Documenting the basis for prioritization decisions supports future budget requests and lender or insurer inquiries.
Implementation, documentation, and progress monitoring
Implementation ties resilience measures into the building’s capital maintenance schedule and sets a cadence for review. An incremental, multi-year approach, of the kind used in capital improvement planning, can help keep resilience work aligned with normal budgeting cycles rather than requiring a single large capital outlay. Funding that schedule often draws on the same reserve mechanisms described in guidance on capital reserve studies, which ties anticipated replacement costs to a property’s long-term budget.
Emergency response planning
A documented emergency response plan is one of the most cost-effective resilience measures available. The plan should specify who responds to each hazard type, which systems to shut down and in what sequence, and where utility shutoffs are located. Pre-establishing relationships with disaster restoration and construction vendors before an event is equally important: contractor availability typically tightens sharply following a major storm, and teams with relationships already in place are better positioned to begin recovery quickly. Reviewing and exercising the plan on an annual basis can reveal gaps before conditions require it.
Key building systems to evaluate in climate resilience planning
Commercial resilience planning gives significant attention to roofing and drainage, building envelope and waterproofing, mechanical, electrical, and life safety systems, and monitoring infrastructure. This section focuses on observable conditions and the thresholds that may signal when professional evaluation is warranted.
Roofing and drainage
Roofing and drainage review centers on surface condition and the building’s ability to shed water within code-defined limits. Water remaining on the surface beyond 48 hours after precipitation may indicate the roof is not meeting the drainage standard. Standing water combined with sagging in the roof deck signals a possible need for professional structural review.
Building envelope and waterproofing
Envelope review focuses on observable signs of water and air intrusion that may indicate the exterior enclosure is no longer performing as designed. Interior staining, efflorescence (white mineral deposits left by water), membrane blistering, and moisture appearing at unexpected locations are observable warning signs. A building envelope evaluation can help establish whether observed conditions warrant deeper investigation.
Mechanical, electrical, and life safety systems
Resilience reviews often evaluate mechanical, electrical, and life safety systems for flood exposure and outage readiness. Backup power systems generally take over within seconds of an outage, and the review considers the rooms housing them for flood exposure. Utility equipment in critical facilities generally sits above the anticipated flood level; a generator placed below that line may represent an elevation shortfall. Emergency egress lighting that dims unexpectedly or fails during testing can support a life safety systems review.
Monitoring technology
Water sensors and automated monitoring systems can provide early warning of conditions that would otherwise go undetected until damage is visible. Sensors placed at common intrusion points, such as curtain wall bases, mechanical room floors, and roof drains, can alert building operators to moisture before it reaches interior finishes. Integrating sensor data with building operations workflows can convert an emergency repair situation into a routine maintenance response. For portfolios spanning multiple properties, centralized monitoring dashboards may support consistent condition tracking across assets without requiring on-site staff at each location.
Turning climate exposure into a documented plan
Climate resilience planning gives building owners and property managers a documented path from physical-risk recognition to a prioritized response. Frameworks from NIST, ASTM, ASCE, and industry organizations support hazard identification, exposure review, vulnerability evaluation, and measures that fit into capital planning and compliance cycles property teams already manage.
Rimkus professionals evaluate building conditions and documentation needs to support resilience planning across property types and portfolios.

Frequently asked questions about climate resilience planning for commercial property
How much does climate resilience planning typically cost for a commercial property?
Cost scales with property size, complexity, and hazard exposure, with budgets driven by the scope of assessment and modeling required. A resilience assessment can often build on condition documentation owners already maintain, such as a property condition assessment, which reduces duplicated field work. Implementation costs depend on the prioritized measures identified during planning and typically integrate into existing capital maintenance schedules rather than requiring a single large outlay.
Is climate resilience planning required for commercial buildings?
No. Climate resilience planning is voluntary, and no federal rule currently requires it for commercial buildings. Related obligations can still apply: some local laws, such as New York City’s Local Law 97, impose enforceable emissions limits on large buildings, and lenders and insurers increasingly request condition documentation during underwriting and renewals. California’s SB 261 climate-risk reporting law is currently not being enforced under a court injunction. Many owners undertake resilience planning to manage insurance costs, protect asset value, and prepare for requirements that may apply later.
How do you assess a commercial property’s exposure to climate hazards?
Start with free public tools. Entering the property address into the ASCE Hazard Tool returns the FEMA flood zone, base flood elevation, and design wind speed, and the FEMA National Risk Index adds context across additional hazard types. From there, an exposure matrix that lists building assets against potential hazards helps evaluate each intersection, following the approach recommended by the U.S. Climate Resilience Toolkit. Pairing that exposure data with observed conditions from a building condition assessment shows where hazard exposure and existing vulnerabilities intersect.
