Yes. Although it is unusual to have a (c)(3) (charitable) homeowners’ association, a (c)(3) charity may make grants for charitable purposes, and helping a hospital during the current pandemic should certainly be considered charitable. It will be closer to your basic purpose of promoting the community if the hospital serves your area.  Even if the hospital is a for-profit entity, as we said in our question and answer yesterday, such assistance would be permissible for a public charity like yours.
