What happens next

Extra Space Storage doesn't take requests with us directly yet, so our team will reach out to the facility on your behalf.
Unless you opt out below, we can also check nearby facilities that have units available. We usually reply within one business day.
The facility confirms availability and price. Nothing is reserved and you pay nothing until you agree to rent.

I agree that Storage Reservations may share my request and contact details with this facility and, unless I opt out below, with nearby facilities, and that someone from them may contact me by phone or email about storage. Storage Reservations connects renters with facility managers; availability and prices are set by each facility, and this request is not a rental agreement or reservation. Only send my request to this facility. Don't share it with nearby facilities.
