There's an entrance on both.
The main entrance is on 14th Street but, there is another on 15th. Go to sacpark.org to reserve event parking in advance at a discounted rate.
FYI, the Memorial Garage splits levels at level 4.So, if you enter on 15th st side you won't have access to level 2. It can be confusing. Keep it in mind.
Main entry is on 4th but you can enter on 15 but remember get your parking ticket in advance it will go much smoother all the way around and assure spot in
