Rewiring in Metro Detroit: what to expect
Much of Metro Detroit's housing was built before modern wiring. Knob and tube, early cloth-insulated cable, and circuits with no ground are common in older bungalows, colonials and two-flats. Blown-in insulation packed around old conductors, brittle wire insulation, and years of add-on work all add risk.
A rewire replaces branch circuits room by room, usually with a new panel. Good electricians fish new cable through existing walls and ceilings where they can, and cut small access holes where they cannot, rather than gutting plaster.
In homes built before 1978, cutting painted plaster can disturb lead paint. Paid contractors who disturb paint in those homes must follow the federal lead-safe work rules, so ask whether the firm is lead-safe certified.
What a proper job includes
- A survey of existing circuits, panel and wiring types
- A room-by-room plan for new circuits, outlets and switches
- New cable, boxes and devices with AFCI and GFCI protection as required
- Panel replacement or upgrade if needed
- Smoke and carbon monoxide alarms installed to current requirements
- Rough and final inspections
- Old wiring disconnected and made safe
What drives the price
- Home size, number of stories and number of circuits
- Plaster and lath versus drywall, and how much wall access is needed
- Attic and basement access for fishing cable
- Whether the panel or service must be upgraded at the same time
- Patching and painting included or by others
- Lead-safe work practices in pre-1978 homes
- Occupied home versus vacant during work

Permits and licensing in Michigan
Rewiring needs an electrical permit from the enforcing agency for your address (the state, county, city or township; in Detroit, BSEED), usually with rough and final inspections. A licensed electrical contractor pulls it, or a homeowner may pull one for work they do themselves in a single-family home they own and occupy. Under Michigan law, renovation of a single-family home that requires a permit also triggers carbon monoxide device requirements near bedrooms and next to attached garages and fuel-burning appliances.
Michigan licenses electrical contractors, master electricians and journeyman electricians through LARA's Bureau of Construction Codes. Check the company's electrical contractor license on the LARA lookup before you sign.

How to compare quotes
- Ask each electrician for a room-by-room scope and the number of new circuits.
- Ask how they access walls and who patches afterward.
- Confirm whether a panel upgrade is included or separate.
- Ask for proof of lead-safe firm certification for pre-1978 homes.
- Check the license on the LARA lookup and compare warranties and schedule.
