What village or is it unincorporated?
Here is a link to a large list if village information in upper illinois.
http://www.lmccdupage.org/electric.htm It has testing, bonding, code cycle, inspector name, address, phone, fax, web site, & email.
Some info may be out dated. I seen Elgin & Gurnee are wrong. Did not look at them all.
For amendments I like to look on the village web site first. For working requirements best just calling.
