A total of two beds in two separate rooms were discovered at Twitter HQ Wednesday when city inspectors visited.
An update from the city's Department of Building Inspection (DBI) says its inspectors, alongside representatives from the Planning Department, visited the eighth and ninth floor offices in the Twitter building on Market Street.
The inspectors found the beds on the eighth floor, and will be investigating further, the update says.
The department opened the investigation in response to reports that bedrooms were installed at Twitter headquarters following now-CEO Elon Musk's acquisition of the company.
City policy requires DBI to send an inspector to investigate all building complaints within 72 hours.
Following reports of the investigation, Musk took to Twitter to challenge Mayor London Breed's priorities in light of a recent incident in which a young child had to be revived with naloxone, also known as Narcan—a drug commonly used to reverse heroin, fentanyl and other opioid overdoses.
Inspectors will now work to determine what city building code violations were broken, if any.
If a violation is found, the department will provide a public update and outline any action needed to correct the violation and provide a timeline.
Some violations require filing a permit within 30 days and paying a code violation fee, which can be up to nine times the permit issuance fee, according to the city's website.
City officials are asking anyone with information or photos to contact them via SF’s customer service email. A complaint about the bedrooms was filed using the city’s 311 service. DBI has said the building codes are in place to make sure people are using spaces safely.
"We need to make sure the building is being used as intended," department spokesperson Patrick Hannan said following the initial complaint.
