How about a boat with an outboard motor attached parked in the unit’s space?One breach that does come up though is the tenant parking their vehicle in the visitors parking space since they have their boat in the unit car space.
Is the boat dangerous or unsightly? Does it smell offensively?
In any case, deal with the illegal car parking and you may solve the problem of the boat. The tenant is a parking thief and should be dealt with accordingly.
