Big Mix-Up with the Alien Tenant

Leo comes down on Earth in a crash he did not plan and needs somewhere to be invisible, so he rents an apartment like anyone else. The problem is that his body does not work the way a human body works. Lights surge and blow when he is upset, objects drift up off tables when he is not paying attention, and the building keeps having incidents nobody can account for. Darnell, the landlord, is a kind man with far too much time to think, and Emily next door writes for a living, which means she is professionally inclined to build a narrative. Between them they decide Leo is a government agent, then a cyborg, then something worse, and they collect evidence accordingly. Leo spends his days denying things and his nights quietly getting people out of trouble without letting them see how, which only produces more unexplained events for Emily to catalogue. The residents eventually stop theorizing long enough to look at who has actually been helping them, and Leo, who came here to hide until he could leave, decides to stay in the building.
