Many Americans live in places where natural or man-made disasters can force them to evacuate on relatively short notice, and find somewhere else to stay for long enough to ride out some hazard. If that hazard destroyed their primary home, homeowners' or renters' insurance can help cover that situation. However, in the case where evacuation was seen as being the best option for preserving one's own health but where there is not significant damage to one's normal home or property there, the evacuee may still be stuck with all those costs of the evacuation, and a claim on homeowners or renters insurance may be viewed as infeasible due to the "small-dollar" aspect.
An example might be those living near wildfires in California, those living in flood/hurricane zones, those living near volcanoes predicted to erupt soon, or those affected but not killed by a nuclear event. A solar storm or cyber attack taking out utilities in a region might also prompt some to leave; an epidemic (in which it's easy to tell who's infected) might as well. Events like an earthquake, 9/11, or the 2016 Paris attacks might lead local area residents to leave temporarily until the dust settles and it can be verified that the area is safe to return to.
If an evacuee needed to fly somewhere to connect with family or other willing hosts, the flight ticket might be pricey last-minute fares. Hotels might also be relatively expensive when booked last-minute during high demand. (Potential destinations for evacuation could be specified in advance.)
There is a category of insurance (or at least insurance-like) products called "home warranties" which have much lower deductibles and lower typical claim amounts than homeowners insurance, intended for e.g. a major appliance breakdown, which provides better budget predictability and is helpful to many customers.
Is there a similar insurance product that covers the costs of evacuation from one's home location?
Travel insurance products that cover evacuation while on a trip away from home do not count as good answers to this question.
