A problem tenant (loud noise, double parking, marijuana, threatens other tenants for complaining) had a vendor double park in the underground garage of a 40 unit building, running hoses up the stairwell, running a generator, that emitted exhaust, for about 2 hours, cleaning furniture in the common area.
tenants complained about the fumes and when asked to park outside, under the tenants instruction the vendor refused.
Aside from parking illegally, quite enjoyment, what rules govern this sort of behavior? I called the police and was informed they could not do anything as no laws were being broken, except for the parking issue.
