Breathial, I had a feeling this would be a problem. Well you have time to look at what solutions are available.
Do you have an family member that would lend you an area in there yard to add a storage container of some type?
Maybe you can find somewhere out of the city that would lease a small area to put a container to store can foods and other items.
I think you need to study this, there maybe many other options for you to look into.
