The salesmen put in the contract "No Permits" and requested that I initial this note on the contract. He indicated that some cities require permits and some cities do not. He cited the fact that Huntington Beach, "a larger city", does not require it but some smaller cities do. He said that no one gets permits in SoCal for windows for single family residence.
Is this true? What is the drawback for not getting permits to install 17 windows?
You should call your city's building department and ask that question.
