​​Our facility features self storage unit sizes from as small as 4'x5' to as large as 40'x40', for rent at affordable rates. There are drive-up, ground floor, second floor and extended access hours options available. You may view all of our storage unit rental rates/prices on the ​​Unit Sizes & Rates Page.


If you need any help discerning which storage unit size is right for you, please visit our Storage Unit & Packing Help page, which features unit graphics to help you visualize what space suits your needs. To see pictures of our larger storage units, please visit this page.


To maximize your security, our units feature high-security disk-detainer cylinder locks and one of three models of disklocks. Cylinder locks are impossible to cut or grind off, unlike standard storage unit locks, while the disk-detainer locking system (normally only seen in the most high-end, high-security locksets) makes the lock extraordinarily difficult to pick or tamper with. The disklocks are high-quality and offer an additional layer of protection on top of the cylinder lock. Both locks feature stainless-steel plates to aid in preventing drilling. All of this is included standard when you lease a unit with Guardian.

Self Storage at Guardian

We welcome you to our website! Whatever brought you here, we hope to impart a sense of the service and professionalism we can offer you in your stay with us. Guardian Storage is a family owned and operated facility that has been providing space and security to our tenants since 1987. 


At Guardian Storage, we offer high-security locks provided standard, personal entry codes, computer monitoring and recording of unit and gate activity, full HD security cameras and 24/7 digital video recording, security lighting, gated and keyed access points. We employ regular professional pest control treatments, professional cleaning services and full-time maintenance on-staff. All units are cleaned and treated with pest-control prior to a new tenant moving in.​


Guardian offers a 10% student discount to students of Cal State Fullerton and other colleges. Guardian Storage is located five minutes from the CSUF campus, down State College Blvd.

Guardian Storage has a full complement of security features to aid in the safe-keeping of your goods.


Secure your unit with the provided top-of-the-line disk-detainer cylinder lock and one of three disklocks.  Each storage unit is individually alarmed with its own motion sensor connected to our computer system; deactivated only with your own personal access code. The storage facility is behind a passcode-protected gate. Units in the yard (excluding drive-up units) are behind locked steel doors (most upstairs units are behind two) and extended-hours halls are also protected by an infrared motion-sensor alarm system. All motion sensor and gate activities are monitored and recorded at the office. Our facility features extensive security lighting as a night-time deterrent.


Our security camera system features all HD, 1080p (35) and 720p (5) cameras and long-term digital recording. Our 40 high-definition cameras are placed all around the facility to maximize our monitoring capabilities. Recording takes place on three independent systems.
