You can usually find a public company's leases in SEC fillings. I couldn't find one for Pinterest, but I found Dropbox's 200+ page lease agreement here: https://www.sec.gov/Archives/edgar/data/0001467623/000119312518055809/d451946dex1019.htm https://www.sec.gov/Archives/edgar/data/0001467623/000119312...
