The cost to rewire a house in San Antonio ranges from $3,170 to $18,140, with most homeowners paying around $7,710. Your actual cost depends on several factors specific to your home and the San Antonio-New Braunfels 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 South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
Budget $180–$810 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Heat increases electrical resistance and can affect panel performance. Consider installing panels in shaded or ventilated areas. Solar-ready panel upgrades are popular and may qualify for local incentives.
This project requires a licensed professional in San Antonio. Attempting whole house rewiring without proper licensing can void insurance and create serious safety hazards.
