The commercial real estate conversation around tariffs and material costs has largely centered on development pipelines, construction budgets, and acquisition economics. These are legitimate concerns. But there is a related risk that has received considerably less attention. It affects not just assets under development, but every commercial property already in your portfolio. The risk is the growing gap between what your insurance policy will pay and what it actually costs to rebuild.
That gap has widened materially. Recent tariff actions on steel and aluminum products have pushed duties on certain imports as high as 25 to 50 percent, with downstream effects on fabricated components, electrical equipment, and mechanical systems. According to the Associated General Contractors of America, citing U.S. Bureau of Labor Statistics producer price data, the PPI for aluminum mill shapes rose approximately 30 percent in 2025. That’s the steepest annual increase since pandemic-era supply chain disruptions. What’s more, the index for steel mill products rose 17 percent over the same period. Engineering News-Record reported that overall construction input prices climbed nearly 10 percent year over year through May 2026, with copper wire and cable prices rising more than 24 percent over the same period.
For investors who have not revisited their property valuations recently, those numbers represent an unexamined exposure sitting inside policies they may assume are current.
The Replacement Cost Problem

Commercial property insurance is built on a foundational premise: that the coverage limit reflects what it would actually cost to rebuild the insured property at today’s prices. When that premise holds, the policy functions as intended. When it does not, the consequences at claim time can be significant.
Most commercial property policies include a coinsurance clause. That clause typically requires that the insured carry coverage equal to at least 80 to 90 percent of the property’s actual replacement cost. When coverage falls below that threshold, the insurer calculates the claim payment proportionally rather than paying the full value of the loss. The formula is direct. If a property is insured for 70 percent of its required value, the insurer may pay only 70 percent of a covered partial loss, less the deductible. As the Insurance Information Institute notes, this proportional reduction applies to partial losses — not just catastrophic ones — meaning a property owner can face a coinsurance penalty on a routine claim without ever experiencing a total loss.
A property insured for $2 million against an actual replacement cost of $2.8 million carries a coinsurance shortfall. Under a standard 80 percent coinsurance clause, the insurer may calculate: ($2M insured ÷ $2.24M required) × loss amount. The result is a meaningful reduction in recovery on every covered partial loss until the discrepancy is corrected.
The valuation inputs that determine whether a property satisfies its coinsurance requirement — material costs, labor rates, systems replacement costs — are the inputs that have moved most significantly in the current environment. A property value that was accurately established in 2023 or 2024, and adjusted only by a standard inflationary factor, may now be meaningfully understated.
Why Standard Renewal Processes Don’t Catch This
Most commercial property policies include some form of inflation guard like an automatic annual adjustment to coverage limits, typically in the range of 2 to 4 percent. In a stable cost environment, that mechanism does meaningful work. When material costs move by 10 to 30 percent in a single year, it is insufficient by a wide margin.
Industry practitioners have documented cases where independent appraisals of commercial properties found actual replacement costs rising significantly faster than standard inflation guard assumptions — producing substantial gaps between the insured value and what a rebuild would genuinely require. As one analysis from InsuranceNewsNet noted, brokers and owners who rely solely on rolling forward prior-year values with a modest inflationary factor may be systematically underestimating replacement cost in a period of acute construction cost volatility. These cases are illustrative rather than universal, but the underlying dynamic — passive renewal assumptions lagging real cost escalation — is well recognized across the industry.
The practical implication is direct: renewal is not a substitute for a valuation review. One updates your premium. The other determines whether your coverage limit still reflects the actual cost of what you are protecting.
The Policy Provisions Worth Examining
Beyond the headline question of whether coverage limits are current, several specific policy provisions warrant attention in this environment:
- Coinsurance clause: Confirm the required percentage — typically 80 or 90 percent — and verify that current limits meet the threshold given updated replacement cost estimates. The calculation should reflect current material and labor costs, not those at the time of the last appraisal.
- Agreed value endorsement: This endorsement waives the coinsurance requirement by establishing a mutually agreed replacement value with the carrier, provided an updated statement of values is submitted and accepted. For properties in volatile cost environments, it eliminates coinsurance penalty exposure entirely — a meaningful protection when rebuild cost estimates are difficult to keep current between policy periods.
- Ordinance or law coverage: When a damaged commercial building must be rebuilt to current code — which often requires upgraded electrical systems, accessibility compliance, or energy efficiency standards — the cost of those upgrades is typically not covered under a standard property policy. In an environment that has elevated the cost of the materials those upgrades require, the gap between what the policy pays and what the rebuild costs can be substantial.
- Business interruption alignment: If a loss forces extended closure, business interruption coverage steps in to replace lost income during the rebuild period. The adequacy of that coverage depends in part on how long a rebuild would realistically take — and in an environment where material costs are elevated and supply chains remain constrained, timelines are longer than historical norms suggest.
The NAIC’s guidance for commercial property owners emphasizes reviewing policy terms in the context of current conditions rather than relying on assumptions carried forward from prior policy periods. That guidance is particularly relevant when the conditions in question include material cost movements of the scale currently documented.
The Practical Question for CRE Investors
The SBA’s framework for business insurance positions insurance as an active risk management function — one that requires periodic reexamination as conditions evolve. For commercial real estate investors, the relevant question is a straightforward one: if one of your properties sustained a significant loss today, would your current policy limit cover what it would actually cost to rebuild it — at current material prices, current labor rates, and current code requirements?
For a growing number of investors, the honest answer is uncertain. Uncertainty, in this context, represents an unexamined financial exposure sitting inside what is intended to be a protection.
Review Your Commercial Property Coverage with Meslee
Meslee works with commercial real estate investors and property owners to assess whether current coverage limits reflect what it would actually cost to rebuild today — not two or three years ago. That means examining replacement cost valuations, coinsurance positions, and the specific policy provisions that determine how a claim actually pays out.
