Natalie,
For meetings of the membership two statutes apply:
VA Non-stock Corporation act ยง 13.1-842 and
VPOAA ยง 55.510 (item F).
Reading these two statutes (and yes there is a bit of conflict between them), a meeting of the general membership requires a minimum of 14 days and no more than 60 days notice (as this will satisfy both of them) OR what the governing documents specify providing they are between 14 and 60 for the annual or regularly scheduled meetings of the membership.
Even though the VPOAA requires a minimum 7 days notice to the membership for any other meeting, if your Association is incorporated (most are) corporate laws require a minimum of 10 days notice.
For Board meetings,
VA Non-Profit Corp Act ยง 13.1-866 and
VPOAA ยง 55.510.1 apply. Basically these laws are saying the following:
a) Membership must be informed of the meeting by posting a notice (no time frame given)
b) Regularly scheduled meetings (1st of each month, every 2nd tues. etc.) requires no notice be given to the members of the Board (membership must still be notified).
c) Special meetings of the Board requires advance notice to Board members but the time frame would be outlined in the governing documents or adopted by the board as a resolution (membership must still be notified).
Since there is no specific time line within the Statutes (and I expect no specific time line in your governing documents) it appears that the Board may determine the amount of notice the membership is given of Board meetings.
However, my advice would be a minimum of 7 if you are not incorporated and 10 days if you are incorporated. I offer this recommendation because this is what the statutes say is minimal notice requirements for a member wanting to attend a membership meeting. Therefore, it makes sense that using these same numbers the board would minimize any lack of notice or improper notice challenge.
NOTE: Sending notice by e-mail does not satisfy VPOAA ยง 55.510.1 which states:
"Notice of the time, date and place of each meeting of the board of directors or of any subcommittee or other committee thereof shall be published where it is reasonably calculated to be available to a majority of the lot owners."
Publishing typically implies newsletters, posting of fliers, placed on a website, advertised in the local paper, etc.. An owner may request that notices be sent by e-mail. However, the Association has a duty to also inform those who did not request notice by e-mail.
