No parking is allowed here.

this is the simplest slogan commonly used abroad.

there is no parking here/there's a no parking area are all wrong.

there be is an inverted sentence, usually followed by a substantive noun, indicating that something appears or has something (for example, there is an apple on the table, the actual structure is: an apple is there on the table, but it is upside down, so there is put at the beginning of the sentence. ) so there be can't be used here, you can use it's instead.

complete sentence:

it is no parking here

parking is not allowed here

parking is forbidden here.
