I've got friends in Belleville. Just consulted with 'em about improving service.
After checking the city website (Vague is a good description), I thought they might not even have an inspector (no mention online)
Yeesh. Here in North Chicago, they were trying the same thing - 80 Year old houses w/60A services mandated to upgrade to 100A, eliminate exposed BX in basements, and hardwire all smoke detectors before occupancy permit/sale allowed. Finally stopped after someone threatened a lawsuit, citing Code when built, and less than 49% renovated.
They still BS people about the BX and hardwired detectors though. But hey, who wants to fight city hall?
