Grafton Self Storage helps families, students, and local businesses find a little more room to breathe. Whether you are downsizing a home, storing seasonal gear between projects, parking a classic car for the winter, or keeping business inventory and documents close by, we offer flexible self storage in Grafton, WI built around how you actually use it.
Our goal is simple: give the Grafton community a storage experience that feels easy from the first click to move-in day. Friendly on-site staff, straightforward month-to-month leases, and a clean, well-managed building are what keep neighbors coming back.

Every unit sits inside a clean, climate controlled building with well-lit hallways, individually secured doors, and around-the-clock security camera coverage. Access is controlled by your personal gate code, and complimentary carts, dollies, an elevator, and a loading dock make moving in and out easy no matter the weather. Indoor parking spaces include trickle-charger outlets to keep your vehicle ready to go, and leases are month-to-month, so you can rent, reserve, and pay online or through the Storage Genie app whenever it suits you.

Below our self-storage building, The Vehicle Vault offers a dedicated underground level built just for vehicles. This newly built, climate controlled space keeps cars, trucks, and motorcycles protected from Wisconsin’s heat, cold, and humidity, shielding paint, interiors, and mechanical parts from the elements all year long. It has its own drive-in entrance at 1327 6th Ave, Grafton, WI 53024, right beneath Grafton Self Storage.
Every vehicle gets its own assigned spot with easy drive-in access and trickle-charger outlets to keep batteries ready, plus the same 7-day keypad entry, security cameras, and on-site management as the storage above. Whether you are tucking a convertible away for the season or keeping a prized vehicle out of the driveway year-round, our underground vault is a secure, out-of-sight home for it.
