There have been at least 2 times in the Portland,Oregon area where permits were
held up by a request from the authorities requiring inspection of the welding
at the factories manufacturing the commercially made towers. The 2 companies
involved were Rohn and US Tower. with some legal help the requirement was
dropped.
I am sure it would have been a real problem to try to permit a tower not from a
recognized manufacturer.

ALL
I would conclude that firstA) Rural areas on a large piece of property the
county might not interfere much, perhaps a building permit but nothing elseB)
Closer to civilization things get progressively harder with regulations,
neighbors etc. County might just not give you any permit at all.C) It may be
best to ask the county offices before relocating with a bunch of aluminium
Liability is an other question: If you have your home made towers A) Is it a
good idea to put a fence around the whole thing, guy wires and all, and put
warning signs so that everybody would know that there is perhaps ice aboveB) Is
it necessary to prevent anybody from climbing a tower with those anti climbing
boards on the bottom of the tower or is high fencing enough?C) How about
verticals with high RF voltage? Fence around or what?
Insurance: Can you insure your tower against forces or nature?
Thanks!
