Is old wiring common in my neighborhood?
Here's the share of one- to three-unit homes built by 1939 in each area, from Minneapolis's current property records, with the office that inspects your electrical permit.

Other parts of Minneapolis
We work in Phillips and Downtown too, the same way as everywhere else. City property records show 83.8% of Phillips's one- to three-unit buildings, 1,416 of 1,689, were built by 1939, and 63.2% have two or more stories, so routing between floors and plaster work come up often. In Downtown, we trace and permit older houses and small residential buildings like any other Minneapolis house, with the Minnesota Department of Labor and Industry inspecting.
Inner-ring suburbs
If your house is in a suburb near the two cities, we work there too, and many have older housing. The U.S. Census Bureau puts the share of housing units built by 1939 at 22.6% in South St. Paul, 14.2% in Robbinsdale (plus 22.1% in the 1940s), 10.9% in Columbia Heights, 10.5% in West St. Paul, 9.1% in St. Louis Park, 9.0% in Hopkins and 7.8% in Edina. Richfield's share is lower, 5.7%, with another 16.7% from the 1940s.
About 66 Minnesota cities run their own electrical inspection, and others use the state's. We confirm which office inspects your suburb, and what it charges, before the permit is filed.
Point-of-sale rules
Sale rules differ by city too. Richfield runs a point-of-sale housing inspection before closing: required repairs are re-inspected before the sale closes, or a buyer can take them on with a repair schedule and a cash escrow agreement, after which the city issues a certificate of compliance. St. Paul requires a Truth-in-Sale of Housing disclosure report. Minneapolis's sale evaluation requirements are confirmed with the evaluator for each house. TISH electrical repairs covers the electrical items these reports raise.
