Yes—there are rental services for urban outdoor furniture for events. Depending on your city and the size of your event, you can usually find party rental companies, specialty event furniture providers, and even hospitality furniture rental firms that supply outdoor pieces. Typical options include bistro tables and chairs, modular lounge seating, high-top cocktail tables, benches, planters, umbrellas, and sometimes temporary barriers or decking for plazas, sidewalks, rooftops, and courtyards.
For public-space or sidewalk events, it is worth asking about permits, delivery and setup, weather backup, accessibility, and return logistics. Some companies offer design-led furniture packages, while others focus on durable commercial-grade pieces. If you need a very specific look, a specialty furniture rental provider is often the better fit; for straightforward seating and tables, a general event rental company may be more cost-effective. In short, yes—rental services exist, and they can make an urban outdoor event much easier to plan.
