I live In a Disabled Elderly Apartment Complex?

Ok I live in an apartment complex for the disabled and elderly ..Over Christmas vacation there was a few snow storms here , when I returned I found that the snow and ice was not removed from my doorway ,and I could not get into my apartment ..
I actually had to shovel ice and snow and hurt my back in the process ..Does anyone know if disabled living complexes are supposed to keep all areas clean of snow and ice at all times ..
Thank you for the great answers , I need to mention , there is no maintainance staff here , they fired them ..And this building is run by , Rural Development of North Iowa ..
