Yes—most modern city trash cans do have some kind of cover, but it depends on the bin. You’ll see domed lids, flat lids with a push flap, self-closing openings, and hooded side slots. These designs are meant to do a few things at once: keep rain from filling the bin, reduce smells, stop wind from blowing litter out, and make the can look neater on the street. A domed top or a small rain hood is especially common because it lets people throw away waste without leaving a big open mouth for water to pour into.
That said, a cover doesn’t make a trash can perfectly rain-proof. Water can still get in through the opening, around the edges, or if the lid is left open or broken. Some cities use open-top or side-opening bins on purpose because they’re cheaper, easier to clean, or better for high-traffic areas. Others add drainage holes so any water that gets in can escape. The trade-off is that covers can also trap odors and moisture, so they need regular emptying and cleaning.
If you’re looking at urban bins as a designer, buyer, or curious resident, check for a domed or sloped lid, a self-closing flap, good drainage, and a sturdy hinge. Those features usually mean the can is designed to handle rain—not just look covered. So yes, covered urban trash cans are common, but “rain-resistant” is more accurate than “rain-proof.”
