How Much Does Electrical Rewiring Cost on a Flip? (2026)
From a quick panel swap to a full rewire — here's how electrical costs scale.
Electrical costs on a flip vary widely: a panel upgrade runs $1,500–$3,000, while a full whole-house rewire costs $8,000–$20,000+ depending on size and access. Many flips only need a panel upgrade, added circuits, and code corrections rather than a complete rewire. Older homes with knob-and-tube or aluminum wiring need the most work.
Electrical is a safety system, so problems flagged by an inspector usually must be fixed before a sale closes. The cost ranges enormously — from minor code corrections to tearing open walls for a full rewire — so it pays to know which you're facing early.
These are general 2026 estimates; home size, wall access, and whether permits and inspections are required move them. Always use a licensed electrician and pull permits.

- How much does it cost to rewire a house for a flip?
- A whole-house rewire typically costs $8,000–$20,000 or more depending on size and access. Many flips don't need a full rewire — a panel upgrade ($1,500–$3,000) plus added circuits and code corrections is often enough.
- When does a flip need a full rewire?
- Usually when the home has unsafe knob-and-tube or aluminum wiring, an undersized or unsafe panel, or widespread code violations. A licensed electrician's inspection will tell you whether targeted fixes or a full rewire is required.
- Do I need permits for electrical work on a flip?
- Yes. Electrical work should be done by a licensed electrician with the proper permits and inspections. Unpermitted electrical work is a safety hazard and can derail a sale when discovered by the buyer's inspector.
