The cost to rewire a house in Baltimore ranges from $3,770 to $21,540, with most homeowners paying around $9,160. Your actual cost depends on several factors specific to your home and the Baltimore-Columbia market.
Larger homes need more wire, more circuits, and more labor hours — cost scales roughly proportionally with square footage.
Modern code requires dedicated circuits for kitchens, bathrooms, laundry, and outdoor areas, so a full rewire typically installs 20–40+ circuits.
Open walls (during a remodel) cut labor costs dramatically versus fishing wire through finished walls, which may require temporary drywall removal.
Pre-1960s homes often have knob-and-tube or ungrounded wiring that requires complete replacement and may reveal other code issues.
Bringing a home up to current NEC code often requires AFCI/GFCI breakers, grounding, and additional circuits beyond just replacing old wire.
The Northeast tends to have higher labor costs, partly driven by stronger union presence and higher cost of living. Stricter building codes mean more inspection requirements — budget extra for permits.
Budget $216–$972 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
In cold climates, expect additional costs for heated conduit runs, insulated wire, and work scheduling around freezing temperatures. Winter installations may cost 10–15% more due to shorter workdays and weather delays.
This project requires a licensed professional in Baltimore. Attempting whole house rewiring without proper licensing can void insurance and create serious safety hazards.

Warning signs include frequent breaker trips, flickering lights, two-prong (ungrounded) outlets, discolored outlets, a burning smell, or a home older than 40 years that hasn't been updated. An electrician can inspect for $100–$300.
Usually yes, though you'll have periods without power in different areas. The electrician typically works room by room. For safety, plan to be out during the panel changeover when the entire house loses power for several hours.
