And if you think this garage just recently came into disrepair, think again. I checked google. It has been a long time coming.
Not a thing has been done by the tenants of the residence, or the owners (not sure if they are the same people). Not a thing has been done by the neighbours. Not a thing has been done by the community, City By-Laws, City Planning, the police, waste management, or any other business / organization / or citizen who may have driven, walked or bicycled past this structure as it falls further and further apart. And how long would it still take if I had not decided to walk down the lane, five blocks away from my house, to find this structure in such disrepair.
Tear the thing down, now, before it kills someone. And while you are at it, drive down a couple of other streets and lanes and see if there are any other potential death threats just waiting to kill some kid.
