Tenant keeps getting mold in bathroom.

[Alexander Rodriguez]

I bought a triplex over a year ago. One of the tenants, who seems to be clean, the times I have entered their property, had a window trim in her bathroom that was full of mold and kept spreading when she cleaned it. The window trim could not be fully cleaned, so I replaced the window trim and made sure the bathroom was very clean. I fixed the exhaust fan which had no connection to the outside, and her window works fine. Now one year later at an annual inspection the mold is almost the way it was in the beginning! I thought I had done everything I could to fix the issue. To start off, I think the tenant should have let me know sooner before it got this bad, am I wrong? And is this an issue I should fix? Is there anything that is my responsibility that can cause this? Or is this a tenant issue? Please help!

The window is IN the shower. It is going to get water splashed on it all throughout the shower. The ONLY way to get rid of the mold is to get rid of a window that LOW. Take that window out and put in a smaller window that is higher that does not get wet once or twice per day. No amount of ventilation is going to keep it mold free.
