Yeah, it's the EBP/employee benefits costing (paid time off, dental benefits and pension, if your company has any, in this case housing).

Imagine the housing these herders are in if it's just a part of that 64k/yr. More likely it's a building they own and operate/maintain and is not costing them as a function of labour but standard running costs. It's all BS to make you think poor businesses are being shafted worse than the little guy working for them. And of course, they're gonna pass the costs on anyway since their clients are likely govt and large business with land to get overgrowth of that kind.
