If the HOA is neglecting a serious safety issue as well as local building code in a common area in the development where you are residing, I would write the HOA a letter advising that it needs to rectify the problem by a set date. Keep a copy of the letter for future use and need.If the HOA fails to make the repairs by the demanded date, I would then make a complaint against it with the local permit and building department in the town where you reside.
