Hoa changing covenants

[Adam Drummond]

does anyone know the legal process that an hoa has to go through in south carolina to change building restrictions.  there is a subdivision that has had restrictions in place and recorded for almost 20 years.  the current arch review committe is not approving building plans that fit under the recorded covenants.  there was a house that was just built in the last month that meets the recorded covenants, but does not meet their new guidelines.  the committee is telling people that the new changes are in place.  i thought that this would have to come to a vote before being put in place?  any advice from anyone out there?  thanks for any input.
