Near a Fire Hydrant.

消防署の通達により、　ここに駐停車できません。　管理組合
しょうぼうしょのつうたつにより、　ここにちゅうていしゃできません。かんりくみあい
Notice from the fire department, you can't stop your car here. Management society (of the building).

I suspect bigger buildings have a kind of maintenance and management office, which is what is probably meant by the management society. The building's management.
