Apartment parking spot

[Josiah Robles]

Hello, I'm 17 and currently living with my mom in an apartment.  The apartment has a parking lot with letters and numbers in the parking space that match the apartments (ex. For apartment 1D there's a parking space 1D and for apartment 4D there's a parking space 4D)  the office that's running our apartment isn't giving me access to a parking spot even tho I live there.  Is that legal for them to do?  Do I have the right to the parking spot that's assigned to the apartment I live in?
