I will be moving into my grandmothers house, and after seven back surgeries my doctor ordered a hot tub and I wish to bring it with me, not opposed to paying higher hoa fees to cover the thirty a month it cost to run it. What's the policy? I would prefer to have my own electric bill so I can add power to the property, eta for this service being available?. The neighbor has enlarged both the kitchen and livingroom areas of their house how do I go about doing that as well? Thanks Michael kohl
