I recently had a new boiler installed in the basement of a rental property which required the city building inspector to come in and inspect. Unfortunately I was not there as I live out of state but the company that installed the boiler and my tenant were with him. During his inspection he noticed that my basement wiring may not be up to code. I'm not 100% sure what is going on but he mentioned to my tenant something about an electrical inspection. I know it would be wise to replace my wiring if it is outdated and not up to code but my question is, can the building inspector require me to replace the wiring? What if I honestly can't afford it at the given time?
