"Our neighbors have a lot of trash" is not a complaint that a city inspector is going to take seriously, and in any case our city was very landlord-friendly/human-hostile. In most cities waiting for the leas to be up and then moving out is always easier...
We resolved this by threatening the neighbor to go to the office that permitted his food truck.
If food truck regulations didn't exist, we would have been SOL until the lease was up.
> Or refuse to haul the trash entirely.
This was an impractical option.
On an 85 degree day, our apartment would stay below 75 (and below 70 until late afternoon close to the end of the workday) if we kept the large front windows open, the kitchen door open, and some well-placed fans. It would heat up to 85 very quickly if you closed off the airflow. Working in 85 degree heat is highly unpleasant.
To say nothing of the rats and fruit flies/ants, which were impossible to keep out of the apartment even when we kept the doors and windows closed.
