There are certain conditions the HOA board must follow when it decides to revise HOA rules. The first thing it should do is look at the laws of the land. Any changes to the rules must not come into conflict with federal, state, or local laws and ordinances. For instance, the HOA cannot prohibit the installation of satellites or video antennas on members' roofs. Having such a rule in place would be in direct conflict with the OTARD rule. In addition to this, any discriminatory or unreasonable rule changes cannot be enforced.
