The E&S Market Explained: What Apartment Owners Need to Know
As admitted carriers pull back from apartment risks, more properties are being placed in the excess and surplus lines market. Here is what that means and how to navigate it.
If your apartment insurance renewal came with a significant premium increase or a notice that your policy is being non-renewed, you may be hearing about the excess and surplus lines (E&S) market for the first time. Understanding what the E&S market is, why apartment properties are ending up there, and how to navigate it effectively is increasingly important for apartment owners.
The insurance market is divided into two segments: the admitted market and the E&S market. Admitted carriers are licensed by each state in which they operate, file their rates and policy forms with state regulators, and are backed by state guaranty funds that pay claims if the carrier becomes insolvent. The E&S market consists of carriers that are authorized to write coverage in a state but are not fully admitted. They have greater flexibility in setting rates and designing policy forms, but their policies are not backed by the state guaranty fund.
The E&S market exists to provide coverage for risks that the admitted market cannot or will not insure. Historically, this included unusual or high-hazard risks. In recent years, however, the E&S market has expanded to include a much broader range of apartment properties due to the admitted market's contraction.
Several factors have driven apartment risks into the E&S market. The most significant is adverse loss experience across the habitational sector. Water damage claims have escalated in both frequency and severity. Hail and wind losses have exceeded historical norms in many regions. Large fire losses continue to occur. And social inflation has increased the cost of liability claims and settlements. These factors have made apartment insurance less profitable for admitted carriers, leading many to reduce their appetite for apartment risks or exit the market entirely.
Properties most likely to be placed in the E&S market include those with significant claims history over the past three to five years, older buildings with deferred maintenance or outdated systems, properties in catastrophe-prone coastal or hail-belt locations, large portfolios that exceed individual admitted carrier capacity, and properties with unique risk characteristics such as mixed-use occupancy or specialized tenant populations.
Being placed in the E&S market is not inherently negative. Many E&S carriers are large, financially strong, and experienced in writing apartment risks. They provide legitimate, enforceable coverage that protects the property owner. However, there are important differences that apartment owners should understand.
First, E&S policies are not backed by the state guaranty fund. If the E&S carrier becomes insolvent, there is no state safety net to pay outstanding claims. This makes the carrier's financial strength rating particularly important. Owners should verify that their E&S carrier has strong ratings from independent rating agencies.
Second, E&S policies may use different policy forms than admitted carriers. The coverage terms, conditions, and exclusions may differ from the standard forms that apartment owners are accustomed to. Owners should review E&S policies carefully, paying particular attention to water damage sublimits, wind/hail deductible structures, mold exclusions, and any coverage limitations that differ from the prior admitted policy.
Third, E&S premiums are generally higher than admitted market premiums for comparable coverage. This reflects the carrier's assessment of the risk and the lack of regulatory rate constraints. Premium taxes and surplus lines fees may also apply, adding to the total cost.
The best strategy for apartment owners in the E&S market is to focus on risk improvement that positions the property for a potential return to the admitted market. This includes addressing maintenance deficiencies, investing in loss prevention measures such as water leak detection systems and security upgrades, maintaining detailed documentation of property condition and improvements, and managing claims carefully to improve the loss history over time.
Working with an insurance advisor who has deep relationships in both the admitted and E&S markets is essential. A specialist advisor can evaluate whether E&S placement is truly necessary, identify admitted carriers that may still consider the risk, and ensure that the E&S policy terms are competitive and adequate for the property's needs.
