Have you checked your windows lately? Do you have any missing or broken louvers? Is there so much grime and dirt on the jalousies that it’s running down the walls? If so, you may be in violation of a house rule.

House Rules Sec III, C. 1. LOUVERED WINDOWS
All residents of units with windows facing the walkways are required to keep such windows clean of dirt and debris at all times in order to prevent accumulated dirt and/or from washing onto common walkways. In addition to assessment of applicable fines for violation(s) of this House Rule, amounts incurred to perform any cleaning necessitated by any violation will be assessed against the unit owner.
All broken or damaged window louvers are to be replaced promptly at the expense of the owner.
Window cleaning & replacement of broken/missing louvers must be completed by May 31, 2025.
