What's different about home rewiring in Baltimore
Gut renovations allow complete rewiring to current code, including AFCI and GFCI protection, while partial renovations require fishing new cable through plaster and shared walls. Permits in Baltimore City come from the Department of Housing and Community Development, and Baltimore County has its own permits office. Planning the rewire together with any service upgrade avoids opening the same walls twice. Basement panels in older rowhomes should also be checked for moisture damage.
Rowhome panels are typically in the basement, and service upgrades are coordinated with BGE. Adding central air, a modern kitchen or a basement apartment usually needs more capacity.
Weather and the utility in Baltimore
Baltimore summers are hot and humid, and thunderstorms bring outages and surges, especially where trees overhang lines. Winter storms bring snow and ice, and tropical storm remnants occasionally cause flooding in low-lying areas near the harbor and streams. Older rowhomes run window units on small circuits in summer, which is a common cause of tripped breakers. BGE serves Baltimore and handles meters, service drops and reconnection; in rowhome blocks, meters are often grouped or located in basements, and a service upgrade involves coordinating with BGE on meter location and access.
