What OSHA issues are you talking about? Install was $140...that included removal of old
signs and installation of two (on on each side). No permit was needed.
Generally speaking, when one is off the ground by more than 2 feet or so, OSHA has rules for the safety of people hanging around in the air, ladders being tied off and proper garments, like steel tipped shoes and some other issues with safety.
It surprises me that you don't have to obtain a permit to take things in the air out and put new things back in without giving your local municipality proof of liability. When telling them you have two men in the air waving 2' x 6' pieces of acrylic around up there.......
especially in California..................
When someone says 'No Permit Was Needed'.... I often wonder, how do you know this ??
Did you literally call the codes department and explain to them what you intended to do and they said.... oh, go right ahead, just don't hurt anyone in the process...... or did someone just ignore calling and think to themselves....
Self, I'm not gonna get a permit, cause I don't think it will take long and no one will know the difference ??
