Thanks for the replies. We are not going to meter the apartments individually, but will monitor it using Cps attached to each meter so we can do an "allowance" The delay in getting sprinklers approved by the state and then installed seems excessive. We don't mind installing sprinklers, but the government delays in this process are absurd. More government=less efficiency and it will translate directly to higher rents charged to customers. In the end the tenant gets to pay for the required changes.
