One variation of a method for managing parking within a parking structure includes: after detecting a license plate number on a vehicle in an image captured by an entry camera unit arranged near an entry of the parking structure, labeling the license plate as unverified in a data log associated with the parking structure; in response to absence of validation of the license plate within a grace period after entry of the vehicle, relabeling the license plate as in-violation in the data log; in response to detecting the license plate in an image captured by a mobile enforcement unit moving through the parking structure, querying the data log for a status of the license plate; and, in response to the license plate labeled as in-violation in the data log, serving a prompt to an enforcement personnel to issue a citation to a vehicle carrying the license plate.
