I go regularly to buildings where the electrical rooms are kept locked, and the tenants don't have a key (both multi and single tenants). It's not unusual to have to drive 5 or 10 miles to pick up a key from the management company.
Although this is a pain in the neck, my concern is more with the tenant not being able to shut off the power in the event of an emergency.
I don't think that this constitutes "ready access", and the tenants should be able to get in the rooms immediately on a 24-7 basis.
What do you think???
