Do all board members need to sign off on new building?

First, this is a new neighborhood and the HOA hasn't even been in effect for a year yet. I followed all the rules and contacted the HOA before we started our building on our lot to get approval. We gave the drawings to the Pres. and the next day he told us it was approved and signed the drawings. We have already started construction and now the other 3 board members are telling us that they didn't know anything about the building and that all of the board members had to sign the drawings to approve it. It doesn't state in the bylaws that every board member has to sign to approve any new structure. So my question is, am I ok and do the board members need to work out this mis-commication among themselves or do I need to hold off on the building?

If I am not mistaken the President by default is "headchair" of all committees...if he signed off on it...then its a done deal.

By no fault of his/her own the President because you are new, may also be new to this community living thing. Like Roger said the board needs to set policy and guidelines following the CCR's for your community.

If the President did this in writing on his/her own and the others are contesting it. Before going forth with it and possibly having it be more trouble for you, like Roger stated ask the Board for an audience with the entire board for them all to sign off on it.

Your board should solict volunteers to serve on committees and one of them should be an ARC review Committee. Have your board set procedures and guidelines following your CCR's.
