We had a problem with bicycles being abandoned in the designated common property bicycle area with racks. There were so many that they were piling up. The Executive Committee held a meeting and resolved to send out a notice to all 213 residents advising that unless they tagged their bike with the owners name and unit number that within 4 weeks they would be removed. 4 weeks passed and all but about 8 that were tagged were removed. No compliants were received. I suggest that you do the same with the objects in the stair well. Stairwells are not storage areas and if there is an emergency and people are vacating the building in little or no light they can be an unintended obstacle.
