What does per-door cost mean in apartment insurance?
Per-door cost divides the total annual insurance premium by the number of units, providing a standardized metric for comparing insurance costs across properties of different sizes.
Per-door cost (also called per-unit cost) is the most widely used benchmarking metric in apartment insurance. It is calculated by dividing the total annual insurance premium by the number of dwelling units in the property. If a 100-unit apartment building has a total annual insurance premium of $150,000, the per-door cost is $1,500.
This metric allows apartment owners and operators to compare insurance costs across properties of different sizes, locations, and construction types on a normalized basis. Industry benchmarks vary widely by region and risk profile. Per the National Apartment Association's annual survey data, typical per-door insurance costs range from $300 to $800 per unit in low-risk, inland markets to $1,500 to $4,000 or more per unit in coastal, hurricane-exposed, or earthquake-prone markets.
Lenders and investors use per-door cost as an underwriting input. Fannie Mae and Freddie Mac underwriters compare the borrower's insurance per-door cost against market benchmarks to assess whether the coverage is adequate and competitively priced. A per-door cost significantly below market benchmarks may signal insufficient coverage, while a cost significantly above may indicate an adverse claims history, poor risk profile, or inefficient insurance placement.
Apartment owners should track their per-door cost over time and compare it to peers in their market. If the metric is trending upward faster than the market average, it may indicate deteriorating claims experience, deferred maintenance affecting underwriting, or a need to remarket the insurance program. A specialized habitational insurance broker can provide market benchmarking data specific to the property's geography and class.
