On Monday, workers were spotted removing the brand’s former bird and logo from the side of the company’s downtown building on Market Street, but the project came to a halt when San Francisco police cautioned that no notice had been given and no safety measures were taken to prevent falling objects from hitting pedestrians.

The sign change isn’t the first time Musk’s company takeover has run into problems with the city. The company has been sued for failure to pay several million dollars in rent for some of its buildings, and was under scrutiny at the end of last year for installing beds in conference rooms without the proper permits.

The company’s old logo has yet to be fully removed from the side of the building.
