Can I use a storage unit as a gym?

Usually not. You can store gym equipment in a unit, but working out there breaks most storage leases, which limit the unit to storage and often bar spending long stretches of time on site.

Leases tend to cover this in two ways. One Florida operator’s rental agreement says the unit is “only for the storing of personal property,” and that the tenant shall not “spend excessive or unnecessary time in or around the Unit.” An hour of lifting several times a week fits that description.

Some cities back it up. Costa Mesa, California requires storage rental contracts to prohibit “uses other than storage.” Porterville, California limits storage facilities to “inactive items such as furniture and files.”

Power is another catch. A treadmill, a fan, or a light for evening workouts needs an outlet, and most units don’t have one. Even where they do, Extra Space says power in its units is “for charging and monitoring, not active use.”

We didn’t find a storage chain that allows gym use. If you want to ask anyway:

• Can I use equipment in the unit, or only store it?
• Are there limits on how long I can stay?
• Do you rent flex units that allow other uses?

A rented garage, a flex unit meant for activity, or a commercial gym membership will usually cause fewer problems.
