For most of us, security is a illusion
I wouldn't be the least worried about hiding my reloading set up unless I have a well reasoned belief that the maintenance people are known to steal from the residents. It's also important that the appartment management follows the renatl laws. In this respect they must inform you at least 72 hrs. in advance that they will be entering your residence for what every reason, with the exception being an emergency problem, such as a water line burst or other type emergency circumstance.
About 20 years ago my Wife was home alone and the landlord decided he was going to enter OUR home, as considered by law as a renter without first notifying us. When my wife came out of the shower and was walking to the bedroom to dress she came face to face with him, she was naked. He nearly got shot moments later when she grabbed the 12 ga. 870 and warned him to leave and never come back without a 72 hr. notice of intention to enter out home, and then must knock first.
I hear your outrage and share it (even though you, your wife and I are not even remotely related that I know of, and that tells you how remote our connection is).
However, what does your post contribute to the thread?
The primary reason I decided to respond to your post, though, is that, How would you know if the maintenance people are known to steal and what could you do about it (aside from moving)? Likely, though, you might be the first, and I would not want to volunteer for that position. (Same reasoning applies to stereos, computers, jewelry, etc.)
The reason I share your outrage is that I am still rankling from being burgled nearly 20 years ago. The sense of violation has mitigated somewhat, but never left. I thought I had lost my Coonan (a gift from a friend) but since I had just moved in, it was still packed and in storage and not delivered yet. Luck alone saved my guns.
The number of hours notice required by Landlord-Tenant Law varies from state-to-state.
When I live in rentals, EVERYTHING I cannot afford to lose is 1) heavily insured 2) locked away out of sight, locked or 3) elsewhere, in a more secure location.
