I can access mine after 6pm at that location. The office closes at 6 but as long as I have my gate code, I can get into my storage unit until 10 pm.
No, this location is locked down and not accessible due to problems with people actually trying to live out of their storage units. Things may have changed and you may want to call and check but my experience was that unlike other Extra Space Storage places that indeed do permit access to their outside storage options...this location is not one of them. Best of luck.
