For North Boulder residents and small businesses who need a little extra room, Guardian Storage Boulder is a convenient self-storage facility on Broadway in the 80304 zip code. The site offers climate-controlled and drive-up units in a wide range of sizes, with daily gate access, onsite management, and packing supplies available right at the office.

Where It Is

Guardian Storage sits at 4635 Broadway, on the same Broadway corridor that anchors so much of NoBo. That makes it a short trip from most North Boulder neighborhoods and an easy in-and-out stop for anyone moving, downsizing, or just clearing out the garage. The Broadway location also keeps it within easy reach of homes, condos, and small businesses in the surrounding 80304 area.

Unit Types and Features

Guardian's Boulder facility offers a broad mix of unit sizes — roughly 12 square feet on the small end up to about 350 square feet for larger needs. Both indoor climate-controlled units and outdoor drive-up units are available, so customers can pick what fits their inventory and access pattern. Climate-controlled units are useful for items that don't tolerate Colorado's temperature swings, while drive-up units are easier for furniture, equipment, and anything that needs frequent loading.

The facility also rents trucks and sells packing and moving supplies on site, which can save a separate trip when you're already in moving mode.



Security and Access

Security is a normal concern with self storage, and Guardian's Boulder location addresses it with an electronic gate, security cameras throughout the property, perimeter fencing, exterior lighting, and an onsite manager during office hours. Gate access runs daily, giving renters flexibility to come and go outside the office's posted hours. Contactless rental and online account management are available for customers who want to skip the in-person paperwork.

Convenient for NoBo

For 80304 residents, the appeal of Guardian Storage is mostly about location. Storing things across town is a recipe for never visiting them, while a unit on Broadway is something you can swing past on the way home. The mix of unit sizes also makes it usable for short-term moves, seasonal gear (skis, bikes, camping equipment), or business inventory overflow.
