After a few years in web development I began working for my dad’s business - we sell commercial doors and hardware and do a lot of work in SF. ADA requirements now force many restaurant to add an auto-door operator (push button that opens door) to their main entry. The total cost can be in the range of $10-15k for hardware, electrical work, union labor etc. this absolutely is a burden that some owners really struggle to afford so I’d argue the “myth” is very much alive. And I’m one of the people making money off this transaction. I have mixed feelings about it.
