Understanding how homeowners make protective action decisions is important for designing policies and programs to encourage those actions and community resilience as a whole. This paper focuses on the role of homeowner perceptions of attributes of the protective actions themselves in influencing household protective action decisions. Specifically, using a combination of revealed and stated preference data from a mailed survey of homeowners in North Carolina (n = 234), we fitted mixed logit models to predict the probability a homeowner has or intends to structurally retrofit (strengthen) her home to mitigate hurricane wind and flood damage. We found evidence supporting the hypotheses that a higher probability of undertaking a retrofit is associated with homeowner beliefs that: (1) The retrofit cost is not too high, (2) the installation does not require too much effort, (3) they understand how it works, (4) it would add to home value, (5) it would protect lives, (6) it would protect property, and (7) it would not make the home less attractive. This work shows that homeowners make retrofit decisions based on a portfolio of perceived attributes that depend on the type of retrofit under consideration. Although cost is important, other factors carry considerable weight in the decision as well. Further, findings suggest that study of one type of protective action (e.g., having an emergency kit) may not be generalizable to other actions (adding hurricane shutters) without considering these attributes.

了解房主如何做出保护性行动决定，对于设计政策和计划以鼓励这些行动和整个社区的适应力至关重要。本文着眼于房主对保护性行为本身的属性的感知在影响家庭保护性行为决策中的作用。具体来说，使用邮寄的北卡罗来纳州房主调查中显示的和陈述的偏好数据的组合（n = 234），我们使用混合logit模型预测房主拥有或打算进行结构性改造（加固）房屋以减轻飓风和洪水破坏的可能性。我们发现支持以下假设的证据，即进行改造的可能性更高，与房主的信念有关：（1）改造成本不太高；（2）安装不需要太多的努力；（3）他们了解如何（4）可以增加房屋价值，（5）可以保护生命，（6）可以保护财产，（7）不会降低房屋的吸引力。这项工作表明，房主根据感知属性的组合做出改造决策，这些属性取决于所考虑的改造类型。尽管成本很重要，但其他因素也影响了决策。进一步，
