I'm ALL for that idea! Livonia already does just that on initial and annual rental inspections, as well as VABO properties. VABO is "Vacant or Abandoned Building Ordinance". It has been in effect since 2009. If a property is vacant for more than 28 days, and the building dept. becomes aware of it, then they will red-tag it. The owner or purchaser is then responsible for bringing everything up to Code, including electrical. If they see a dangerous or obsolete panel (FPE, Zinsco, Pushmatic, screw-in fuses, etc.), they will call for a service upgrade to be done by a licensed electrician. I've done many service upgrades under that ordinance.
