The LL is not responsible to you for the noise created by the garage doors as they open and close. The LL is also not responsible for the general cleanliness of the unit, whatever that means.
If there is a termite infestation or other rodent or insect infestation you should provide your landlord in writing in notice of the issue. Same goes with the electrical issues, mold and lack of safety detectors. If he fails to remedy the issues then send another written notice and demand that he fix the issues. If he continues to neglect his/her duties as a landlord then there are certain steps you can take such as the "repair and deduct remedy" or the "abandonment" remedy.
