Reno, that tree thing is not a building department, it is a zoning department thing. Those people are just nuts. We wanted to put in a half basketball court here in my little community (47x50) The building department said no problem, we didn't even need a permit if we were not ever going to put a structure there. Then the zoning people stepped up. They said we needed a development order ($350) that required a 27 page application, a public hearing and a sign off by the zoning board. Long story short, 4 months later we poured the slab.
