6/9/15 Parking Concepts, 1575 Grant Street, Concord
This parking garage is only a block off of Clayton Road, near the Concord BART station. They have parking for monthly tenants and also guests who can pay by the hour. Two lanes of guest traffic flow into the garage and you take a ticket as you enter. The first time I pulled in, the ticketing machine on one guest side wasn't working and it took a few minutes for the car behind me to figure out that I had my reverse lights on for a reason. They gave me room to back out, then pulled up themselves to the broken machine instead of following me to the other side. Ha!
Parking rates are really reasonable - $1/hr, and you can pay quickly with your credit card as you exit. Don't lose your ticket. (And perhaps you can ask for validation, depending on where you are going?) Guest parking has a lot of "compact spots" and our Altima is more of a mid-size car, but fits in the little spots pretty nicely as long as the surrounding cars aren't on the line (which they always seem to be). 
It's a convenient garage for visiting friends in the Bank of America corporate building, and a short walk to Todos Santos Plaza. The garage itself is really pretty on the outside with green vines decorating one side of the building. The stairs are clean and there are also elevators to move between floors. The doors are automatic so push the big button to walk out of the garage - but do NOT push on the doors themselves. (There are signs to remind you of the auto feature). And don't forget to pay attention to where you are when you park - it's a big garage with many levels.
