Mitch S. - 5 March 2026
I needed storage at the very last minute on a SUNDAY this place was the only one I found that could actually accommodate me so I would be able to move in the same day. I made the reservation online and called not even 5 minutes later and Ryan was able to email me all the paperwork and get me signed in on the online portal. He walked me through everything! Really was a live saver. We were in the middle of moving to a new house only to find out we had been scammed so we had no where to take our stuff. These guys really came in and saved the day!! Thank you so much! ... Read more

I have had no issues since renting my unit. I have been at the same storage facilities for over 12 years. Since Rocky States has taken over the place has done nothing but get better. I can always count Travis and the crew to answer any questions within the same day that I have left a message. When I have ran into income problems they have always been happy to help with rearranging my payments or moving my payment date to corelate with my pay check. I wouldn't rent anywhere else. I highly recommend Rocky State Storage to all my friends and family. Keep up the Great Job!! ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Rocky State Storage - 23315 CO-257 has to offer. These amenities include Drive-Up Access, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, First Floor Access, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Rocky State Storage - 23315 CO-257 can satisfy all of your storage needs. Different sizes here range from 50 to 540 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Rocky State Storage - 23315 CO-257 come at a variety of prices, starting from $100 per month for typically smaller units. However, larger spaces can set you back up to $295 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
