Abandoned buildings are something we automatically learn to ignore, which makes them the perfect cover for someone who doesn't want to draw attention to themselves. Like certain less-than-legal businesses, or the Masquerade. Which means that that abandoned building off in the distance, might not be so abandoned after all, it's just kept looking that way to keep out the curious.

- In Ant-Man, Scott tries to steal a MacGuffin from an old Stark Industries storage facility by taking an army of ants to break in. Only when they arrive do they realize that it's not quite as abandoned as Scott and Pym thought, as it's been turned into the Avengers Headquarters!
Scott: Hank, didn't you say this was "some old warehouse"? It's not! YOU SON OF A BITCH!

- Raylene from Cherie Priest's Chesire Red series is a cat burglar who owns a seemingly abandoned warehouse to store things she's stolen.

- In Robert Westall's The Machine Gunners, the gang of children build their secret fortress in the garden of a house that's been destroyed by a bomb blast and deliberately spread false rumours about seeing ghostly lights and other spooky things there to help keep people away.

- The dilapidated planetarium in the aptly-named online puzzle-story Planetarium is ignored by the townspeople and seems to be abandoned, and the story's narrator even points out that the mathemagician's purchase of it is a curious one, considering that he doesn't even visit it all that often. It, of course, turns out to have more than one surprise and living thing hiding in it.
- Evil Genius 2 works an Exploitation of this trope by the Forces of Justice early on in the game. Your Evil Genius will be vexed at why the good guys continue to send agents to investigate your operations on the abandoned island and cause delays to their plans because their minions keep having to stop and fight them; one of the minions will point out that all the helicopter visits your minions need to get on and off the island rather breaks the fiction that the island is abandoned.
