Do companies selling metal buildings, located out of state, for contractors in California qualify as falling under the HIS registration requirements. I am dealing with an out of state sales company selling metal buildings for in state contractors. Got a quote for a building, agreed on price and requested contract to execute. Contract provided had one item spec'd wrong and not compliant with quote. Requested revised contract. Received revised contract but had added bracing items in addition to original quote (+$1,446). HIS said it was a new company policy he was not aware of when he did our quote. Then we are told the state of California requires it which tells me it should have been included in the original quote. Then we are told the contractor requires the additional bracing. We had to sign the contract because we are against the wall with our insurance company (storm damage) but I still question the addition. The contract states they can increase the cost without notifying us. Market forces and material availability did not increase the cost. A HIS error increased the cost. We have signed the contract and paid the deposit. We have not yet received a fully executed contract with their signature. John Damon P.E.
