Here's another angle for you to consider:
The Maryland Legislature has adopted laws requiring disclosures to purchasers that a lot is located within a homeowners association for which fees must be paid; sets forth warranties; rules regarding meetings of the association; family day care activities and other aspects of homeowners associations. The Maryland Homeowners Association Act is codified and can be found in the Annotated Code of Maryland as part of the Real Property Article, Title 11B. The Act is refined by amendments from year to year. Here's the URL: http://www.dsd.state.md.us/comar/Annot_Code_Idx/RealPropIndex.htm#Title%2011B
You'll have to page through the different sections with the Previous and Next links. You can Google the Act and find prettier copies (pdf, even!).
According to section 112, there are only specific reasons for which a Board may withold disclosure of the Financial books. Below, I've enclosed the text from section I referred to. I liked the suggestion for you to contact the Maryland Office of Consumer Affairs, but you might consider consulting with a Real Estate attorney, who might be willing to tell you up front if your case has merit or not. Referring back to Title 11B, section 112, you'll probably need a lawyer's opinion as to what constitutes "disclosure". In my opinion (not a lawyer!), subsection 112(a)(1) seems pretty straightfoward that you ad a member of the association, have a right to see the books. However, reasons & specific disclosure exclusions are in subsection 112(a)(2). Not sure if an audit would be construed as being a "public inspection." You probably should have a Real Estate Attorney tell you that!
Hope this helps:
