Hi! I'm the President of an HOA in California. Over the last year, we have had increasing issues with our landscaping company. Their work has gotten really bad. They heard that we had gone out to bid for our work and they terminated the contract early. We did not pay our June monthly fee because we believe that we have offset against their fees for prior work that we paid for. We sent them a 4 page letter with over 50 pictures. Their response was to threaten to file a Mechanics Lien against us. I don't see how mowing lawns and trimming bushes would qualify as improvements to real property. Any ideas?
