Nothing to get excited about, most condos don’t provide access to any service shut offs, they are locked but maintenance people have the key. Townhomes usually have water main shut off, but there will likely be one for the building as well somewhere. There are multiple shut offs in apartment buildings, most apartment units do not have a water main, but floors might, the building does for sure, and there will be also be ones out on the street for the utility. A tenant with a shut off in their unit will be (should be) instructed by the condo association that even though it is in their unit it is not theirs play with. Like getting the emergency exit door seat on the airplane, just because you are sitting there doesn’t necessarily mean you get to use it.
