I've lived in my home for 7 years... Never have I ...

I've lived in my home for 7 years... Never have I heard that ur allowed to have a clothesline umbrella but yet I can't have a gazebo which I can put up and take off at anytime... UNBELIEVABLE... No trees around my house... No shade around my house... Can't put up a gazebo to sit outside with my family cause they don't allow it!! How am I suppose enjoy my house outside with my family if I can't even put up a gazebo? Oh and it can't b on the grass... but yet if I built a deck I can have it on there!!
