Jeff,
This is going to depend on your applicable COA/HOA laws and your governing documents.
A quick search of
those statutes section 5302 specifies that the Power of unit owners' association include [emphasis added]:
(11) Impose charges for late payment of assessments and,
after notice and an opportunity to be heard, levy reasonable fines for violations of the declaration, bylaws and rules and regulations of the association. The law, doing a quick look (so I may have missed it), does not require the posting of a fine schedule. It also doesn't define what a "reasonable" fine would be. Therefore, you would have to see if your governing documents (CC&Rs, Bylaws, Articles of Incorporation, resolutions) specify any requirement. If it does not, then there may not be a requirement.
To mandate such a requirement, you should gather your neighbors together and propose amendments to the governing documents (the higher the document the harder it is to amend it).
Hope this helps,
Tim
