Electrical Problems in Old Baltimore Rowhouses: A Safety Guide

Many homeowners navigating electrical problems in an old Baltimore rowhouse face the legacy of knob-and-tube wiring or outdated cloth insulation that simply cannot support the energy demands of modern life. These historic properties, often built before 1950, were never intended to handle high-draw appliances like smart home hubs, central AC units, or electric vehicle chargers. As a licensed electrician in Baltimore since 1999, we frequently see the risks associated with overloaded circuits and ungrounded systems that fail to meet current NEC codes. When these aging systems are pushed to their limits, they create significant fire hazards that put your property and family at risk.
