The original post says that a letter was received from the strata manager, not that a notice to comply was received. I believe that before a notice to comply is issued that a meeting of the EC should be held. However, if someone complains about a breach of by laws to the strata manager, then they can send out a letter.
A lewould from the SM would be a formal way of letting a resident know that they are in breach of. Having this formal record would facilitate taking any further action if necessarythe attempts have been made to advise the resident of this breach so they can stop doing it. To get a letter about a breach is not bullying.
I too have a garge where my car just fits in because of all the stuff stored there. I have two choices when I need to get/do something. I can park on the street or get rid of the stuff. Just like everyone elose in the complex.
