Short answer: many street benches do, but definitely not all. If you order a typical commercial park bench with cast iron, aluminum, or powder-coated steel legs, the mounting feet usually arrive with pre-drilled holes or slotted holes ready for anchors. Budget models, some recycled plastic benches, and in-ground designs often skip them, which means you’ll be drilling on site.
The type of bench makes the biggest difference. Surface-mount metal benches are the most likely to come pre-drilled. The base plates or feet usually have holes sized for 3/8-inch or 1/2-inch concrete anchors, and some manufacturers add oval slots so you have a little adjustment room when the concrete isn’t perfectly flat. Wood-and-metal benches often have a steel or cast iron frame with pre-drilled holes, while the wood slats are simply bolted to the frame and aren’t meant to anchor the bench.
Recycled plastic benches are less predictable. Some brands mold mounting holes into the legs or include steel inserts, but many leave the legs solid because they don’t know whether you’ll surface-mount, in-ground mount, or just place the bench on pavers. If you’re buying that style, check the product sheet for wording like “pre-drilled mounting holes,” “surface mount kit,” or “anchor holes included.” If it doesn’t say, assume you’ll need to drill.
In-ground benches are a separate case. Their legs are designed to be set directly into wet concrete, so they typically won’t have bolt holes at the base. That’s normal and not a defect. Wall-mounted benches or backs, on the other hand, almost always have pre-drilled brackets because they have to be fastened to a vertical surface.
Before you install, inspect the bench. If the holes are there, use hot-dipped galvanized or stainless steel anchors, washers, and nuts so the hardware doesn’t rust and stain the concrete. If the holes aren’t there, place the bench exactly where you want it, mark the hole locations through the base or with a center punch, and drill with a bit rated for the material. For steel frames, use a cobalt or titanium bit at low speed with cutting fluid. For aluminum, a standard metal bit works fine. Go slow, and don’t over-tighten the anchors, especially on concrete edges, or you can crack the slab.
One more thing: even if a bench comes with pre-drilled holes, it usually won’t include the concrete anchors. Some manufacturers sell a mounting kit separately, while others expect you to buy wedge anchors, sleeve anchors, or concrete screws locally. So the bench can be ready to mount and still not be a one-box job.
Bottom line? Most standard commercial street benches have pre-drilled mounting holes, especially surface-mount metal and wood-frame models. But never assume. Check the spec sheet, look at the base plates when the bench arrives, and be prepared to drill a few holes if needed. That’s the realistic answer from somebody who has installed both kinds.
