No law requires the HOA to inform all homeowners in the Association of its actions; that is, nothing says it must send out written notices of it, put it on its web site, or whatever. However, California law does require that when a homeowner makes a request for inspection of Association records the Association must make them available for the homeowner to inspect at times specified in the statute. See Cal. Civ. Code § 5210. You may also copy the records, but the HOA may charge you a reasonable fee for its expenses in copying the records. Among the records that must be made available are records of board meetings and committee meetings, with the exception of meetings in executive session. See Civ. Code. § 5200 which excludes records of executive sessions of the board from the definition of Association records. Section 4910 provides that the Association may not take any actions outside of a board meeting.
Executive sessions of the board are allowed for the following discussions:
(a) The board may adjourn to, or meet solely in, executive session to consider litigation, matters relating to the formation of contracts with third parties, member discipline, personnel matters, or to meet with a member, upon the member’s request, regarding the member’s payment of assessments, as specified in Section 5665.Civ. Code. § 4935.
(b) The board shall adjourn to, or meet solely in, executive session to discuss member discipline, if requested by the member who is the subject of the discussion. That member shall be entitled to attend the executive session.
(c) The board shall adjourn to, or meet solely in, executive session to discuss a payment plan pursuant to Section 5665.
(d) The board shall adjourn to, or meet solely in, executive session to decide whether to foreclose on a lien pursuant to subdivision (b) of Section 5705.
(e) Any matter discussed in executive session shall be generally noted in the minutes of the immediately following meeting that is open to the entire membership.
Deciding on a general enforcement policy for violations of the rules would seem to fall under "executive session to discuss member discipline" though I've not checked California court decisions to see if they have interpreted it that way. If it does, then if the board did it correctly it would have gone into executive session to discuss it, in which case the details of the discussion would not be a record members could get. However, the regular board meeting minutes would have to at least mention that the issue was discussed. If they failed to go to executive session to discuss it then the discussion must be in the regular meeting minutes and that would be available to the members.
