My wife found this moth fly inside our apartment and I photographed it last night. Might have emerged from one of our drains? I think this may be Telmatoscopus albipunctatus? Powell and Hogue (1) illustrate this species and state that it's common in California, calling it the "Bathroom Fly".

From an Urban Entomology text, here:

"Telmatoscopus albipunctatus (Williston): This is one of the moth flies that infests sewage filter beds and drain pipes (figure 319 A, bottom). It is widely distributed over the United States. The specimen shown in the figure was one of many that emerged from the drain pipe of an infrequently used sink, with a leaking faucet, in a glasshouse on our Los Angeles campus. Its color is generally brown or blackish, but with the white hairs on its thorax and antennae rather conspicuous. These features, along with the white spots at the tips of the wing veins, clearly seen in the figure, make this a well-marked species that is easily distinguished from other North American species of the genus (Quate, 1955)".
