Our building code says that permission is needed only if you have other homes within 300 Ft. which is only a few deer. I am going to sneak in an above ground with decking for the time being our house is elevated so I can get away with blending it in. After building a new house and losing 60% of my wealth to taxes and market drops $3000-4000 tons better than 50K and the kids won’t know the difference.
