Detroit has a humid continental climate with extremely cold winters (regularly below 0 °F during polar vortex events), warm humid summers, and moderate lake-effect snow from the Detroit/Windsor area. The November-April heating season dominates annual energy use. Pre-war Detroit housing commonly has knob-and-tube wiring, galvanized supply lines, and 60-100A service; renovation typically triggers system upgrades

Knob-and-tube (K&T) is early electrical wiring (1880s-1940s) common in pre-war Detroit housing. K&T has no ground wire, is fragile when disturbed, and conflicts with modern insulation. Many homeowner insurers require K&T removal as a condition of coverage. Replacement runs $7,800-$14,000 and is often done during whole-home renovation.
Aluminum wiring (1965-1973) was common in Detroit mid-century housing. Aluminum oxidizes at terminations and can create fire hazards. AlumiConn or COPALUM connector remediation runs $75-$150 per junction; full replacement runs $5,500-$10,000. Insurance companies increasingly require aluminum wiring remediation as a condition of coverage.
