1. Notice patterns when certain things occur. Note whether they happen day or night, include times, and look for other things that are worth mentioning if the issue(s) end up in court.
2. Set up recording devices if the issues are happening inside your unit.
3. Take photos of all things related to your troubles.
4. Ask a trustworthy neighbor to watch out for things that are troubling.
5. Write down what neighbors say about the problems. Note dates and times you interviewed with them. Keep in mind, there will be those neighbors who don't want to rock any boats, so don't mention what you are doing to them.
6. Get the police, health department, building inspectors, code enforcement, and others involved if you feel your safety is at risk.
Using your best judgment when it comes to apartment maintenance, noise, unresponsive landlords, neighbor issues, and more can be beneficial, but do keep in mind that troublesome individuals don't like to be reported. So do make plans to move if your conditions are unbearable and also consult with an attorney and your local Housing Rights office.
