Pretty much everyone I work with in the US worked from home at least some of the time even before this. I'd place a sizable bet that not one of them has ever had an OSHA inspector come to check out their home workplace.
I think if its the odd day you might getaway with it - but when your workplace is formally defined as your home it might be very different. I suspect it for the USA it will be the medical insurers that will insist on it.
I was curious if there actually was a technical requirement that no one followed in practice. But no. Home offices are explicitly out of scope--although there may be some reactive oversight for other home-based worksite activities.
Policy for Home Offices.
OSHA will not conduct inspections of employees' home offices.
OSHA will not hold employers liable for employees' home offices, and does not expect employers to inspect the home offices of their employees.
If OSHA receives a complaint about a home office, the complainant will be advised of OSHA's policy. If an employee makes a specific request, OSHA may informally let employers know of complaints about home office conditions, but will not follow-up with the employer or employee.
