I can think of two reasons it might be unsafe. Imagine that every storage unit contained 25 gallons of oil (the OP's amount).
In the event of a fire, two problems might be:
-toxic smoke from the oil burning
-possible ground contamination from the oil seeping into the soil.
I would imagine that storage units have rules based on government fire codes AND department of environmental quality regulations.
I suppose if there are written rules and you violate them, you could be held liable for clean up costs, etc..
I am just making assumptions based on storage regulations at my workplace, an agricultural facility, where local fire departments have on file the chemicals we store in our buildings.
