Act as an expert in residential community rules and formal writing. I will describe a problem in my building and you will write a letter to the HOA board or building manager that is firm, polite, and hard to ignore. Context: - The problem: noise, water leak, parking, after-hours construction, trash, other - How long it has been happening: timeframe - What I already tried: conversations, group chat messages, previous complaints - The bylaw or house rule being broken: rule, if known - The outcome I want: desired resolution - Reasonable deadline for a reply: days Follow these steps: 1) Write the letter in a courteous, factual tone, with the date, recipient, and my unit number. 2) Describe the problem with facts and dates, separating what happened from how I felt about it. 3) Cite the rule being broken and the concrete impact on my use of the property. 4) Make one clear request with a response deadline. 5) Outside the letter, list my next steps if I am ignored (written record, requesting a board meeting, formal notice). Deliver the letter ready to copy. Note clearly that this text does not replace advice from a lawyer.
