Letting contractors in when not home/emergency

[Account Closed]

I had my first minor emergency a short time ago-a plumbing leak that had water squirting out of a supply shutoff valve inside a unit. Happened during easy daytime hours on my day off work. Handled it. Cool. :)

Then little old newbie landlord got to thinking, “Crap?!? What if I’d had to handle this by PHONE when I was AT work?”

Here’s an idea that I think works. Can you offer feedback on it, or how you would handle this?

Lockbox with building entry key inside, attached to a wooden post in back of property. Easy to find, but also not sitting in plain sight to passers by.

I thought if that box was broken into by a vandal or thief they wouldn’t be able to gain immediate access to tenant units if I only put the outer door’s key inside it. Thinking I should use another locking barrier inside the public area of building for key(s) to access tenant units though? (Opinions? Is this making it needlessly complicated or paranoid?)

Once my helper/contractor/etc. has the key to building, should I put the master key that opens all 4 units in another combination locked container? Or is it required or general practice to give access to individual units only, and lock each key in its own combination locked lockbox or closets? (I actually do have unused storage closets right now. I was thinking of claiming them for my use anyway, so, it would be a doable plan)

Thanks for your thoughts.
