Extra Space Storage
Self-storage and vehicle storage on Arapahoe Ave in Boulder, rated 4.8 stars across 934 Google reviews.
Boulder sits right up against the Flatirons, and parking anything bigger than a hatchback here takes some planning. The directory lists 3 car and vehicle storage facilities in town, with 4 more nearby, averaging 4.7 stars. One of the three runs 24/7 gate access, which matters if you work odd hours. UV out here is no joke, so think about cover even when a spot is outside.

Three facilities show up for vehicle storage in Boulder, and none of them are listed as covered, indoor, or outdoor specifically, so call and ask what the space looks like before you commit. Two of the three are Extra Space Storage locations, rated 4.8 stars, and the third is StorQuest Self Storage at 4.5. What you get with StorQuest is a gated property with 24/7 access and climate control, plus boat storage if you have one. Cameras show up at the highest-rated Extra Space site. Boulder County hail season is real, so ask about overhead cover where you can get it.
Boulder is a tight town with narrow streets and limited on-street parking, which is exactly why people rent space instead of shuffling rigs around the driveway. Check gate hours before you sign, because a facility that closes at 8pm will not help you when you roll in late from a trip. Read the rental agreement for what they allow you to do on site, from washing to minor repairs, and confirm your auto or RV insurance covers the vehicle while it sits. Then measure your rig, hitch to bumper, and ask for a space with room to open the doors.
Colorado sun fades paint, cracks dashboards, and eats tires faster than most people expect, so cover or shade is worth asking about. If the vehicle sits for months, pull the battery or put it on a maintainer, and top off fluids before you park it. Fill the tires to spec and check them before the first spring drive. Boulder gets cold snaps that can split a block if you store something without proper antifreeze, so winterize anything with a water system. The 4.7 average rating across these facilities suggests people are generally satisfied, but visit in person and look at drainage and fencing before you pay.
There are 3 listed in Boulder, with another 4 nearby if you are willing to drive a bit. That gives you a few options to compare on price, access hours, and security features before you pick one.
Yes, one of the three has 24/7 gate access, and that is the StorQuest location. If your schedule is unpredictable, that is worth confirming directly, since the other two may keep limited office or gate hours.
The current listings do not break out covered or indoor spaces for these three facilities, so the safest move is to call and ask. Given Boulder County hail and strong summer sun, overhead cover is worth pursuing if any of them can offer it.
Ask about gate hours, confirm what your insurance covers while the vehicle is parked, and look at the lot's drainage and fencing in person. Top off fluids, fill the tires, and use a battery maintainer if it will sit for months.
