We are having a pool deck built for our above ground pool that is about 4 ft high which means that when we are hangin out up there we can see our neighbors back patio where they have a sliding glass door with no blinds, curtains, etc. We knew the deck would be high and we were going to be able to see them and vice versa-- this is why we are also building a lower level platform attached to the deck that is about 2 1/2 ft high so we are not always so high up there. Sitting at this level they cant see us and we cant see them. Our deck is also having railing all around it. if we are up there on the top level we will be sitting with our backs towards them and the only time we will really be standing is when the kids get in the pool. These are our only neighbors back there that have a view of this area in our back yard (i live in a culdesac). When we were up there last night checking out the builders progress, those neighbors (whom we dont know...they live on the street behind us) were staring at us with there hands on there hips looking furious. My little son took it upon himself to wave and they didnt wave back. So i know they are upset about this. Once its all built though we will put a table and chairs on the lower level to try to keep the peace but I didnt built the part thats level with the pool for nothing! My kids will be up there Im sure. So my question is.... is there a law that Im breaking by building this...the builders said they didnt need a permit???? Should I feel bad like I do???
