San Francisco investigates Twitter and Elon Musk's building code violations.

San Francisco authorities are investigating Twitter over possible building code violations after six former senior employees filed a lawsuit against the company, accusing it of breaking local and federal laws and violating building codes in its effort to turn some of the rooms in its headquarters into bedrooms for employees. The lawsuit also accuses Twitter of not paying promised severance and rent. The investigation is being conducted by the San Francisco Department of Building Inspection.
