As City Attorney, Aguirre filed a legal action to force a developer to reduce the height of an already constructed office building near an airport. Federal Aviation Administration officials had later determined that the height of the building posed a threat to public safety, even if a city building permit had been issued. In 2009, a California Superior Court judge affirmed the City Attorney's position by determining the developer had no legal right to erect the building to the unsafe height, and the top several stories were ordered to be removed from the building.
