The change of the Twitter logo from a blue bird to a black ‘X’ has landed the company in trouble with the government of San Francisco city, the city where the company is headquartered.

Daily Mail reported that the foremost social media company installed its new sign atop its large building in San Francisco on Friday in violation of the city’s building codes.

Prompted by this development, government investigators moved to Twitter’s office for inspection but were denied entry.

Placing the logo on a building was considered possibly unsafe, but a representative of Twitter told officials it was a “temporary lighted sign for an event”.

The officials returned to the microblog’s office on Saturday and were refused access to the sign on the rooftop.

“A building permit is required to make sure the sign is structurally sound and installed safely. Planning review and approval is also necessary for the installation of this sign,” Patrick Hannan, spokesperson of the San Francisco department of building inspection, was quoted to have said in a statement.

The statement pointed out that to ensure “consistency with the historic nature of the building, and to ensure new additions are safely attached to the sign”, a government-issued permit was required.

According to the report, Twitter is prohibited from altering the rooftop of its office. In the event it desires to change the original designs, its lease agreement requires it to obtain the building owner’s permission.

Musk had earlier posted on his page that he remained committed to staying in San Francisco despite an offer of rich incentives.
