Seeking Compact Space for Gym Equipment Storage and Use

Due to the passing of our rental home's owners, we're having to move which means I'll be losing my backyard gym space where I workout. I'm on the lookout for a small space - 10x12 minimum, like a storage area, barn, or half a garage in Palo Alto or adjacent area - where I can set up a squat rack, adjustable dumbbells, and a bench to continue training myself. Ideally, looking for a cement floor to avoid damage from weights being dropped. I'd be happy to pay a monthly fee and share the equipment with the space owner as a thank you! If you know of anything, I'd really appreciate it. Thanks for considering!
