Residential Electrical Safety Inspections in the Twin Cities

If you are selling a home in Minneapolis, the city requires a Truth in Sale of Housing evaluation, usually called TISH, before the property is sold. A TISH report is valid for two years or one sale, whichever comes first, so a report from a previous transaction may still be live.

TISH is a disclosure, not a pass-or-fail test. The evaluator records the condition of the house so a buyer knows what they are getting. On the electrical side, the disclosure records the service amps and volts, and three items matter most:

• Item 12, electrical service installation. The condition and adequacy of the service itself.
• Item 13, a separate 20-amp kitchen circuit, indexed at the panel.
• Item 14, a separate 20-amp laundry circuit, also indexed at the panel.

“Indexed at the panel” is the part sellers most often miss. It is not enough for the circuit to exist. It has to be identified in the panel directory so an evaluator can find it. A correctly labeled panel resolves a surprising number of TISH comments on its own.

Two findings come up repeatedly on Minneapolis TISH evaluations: an ungrounded panel, and a GFCI that will not trip. Both are electrical work rather than paperwork, and both are far more comfortable to deal with before a report is written than after.

Neither is surprising in a city where the assessor’s 2025 parcel data puts 68.4 percent of single-family parcels, 51,513 of 75,257, at a build date before 1940. A house built in 1912 was not wired with an equipment ground, and the GFCI in the bathroom was almost certainly added decades later by somebody who is no longer available to ask. The panel directory has the same history written on it: forty years of added circuits, three different handwritings, and a laundry circuit that exists but is labeled “basement.”

It is worth being clear about what TISH does and does not force you to fix. Most items are disclosure only. The City’s Common Required Repairs list, the items that must actually be corrected, contains exactly one electrical item: exposed wires or open junction boxes with uncapped wires. Everything else on the electrical side is disclosed for the buyer’s information, and what you do about it is a decision, not an order.

That distinction matters, because sellers are sometimes talked into a full panel replacement they were never required to make. We will tell you which findings are required repairs, which are worth doing because a buyer will ask, and which you can reasonably leave alone. Book an inspection before your evaluator arrives and you will know what is coming.

Two Minneapolis houses can be five miles apart and fifty years apart electrically. In the Holland neighborhood in the Northeast, 75.3 percent of buildings date from before 1940. In Fulton in southwest, it is 69.5 percent and in Whittier, 54.4 percent. In Armatage, also in the southwest, it is 4.0 percent. An inspection in Holland is largely an exercise in reading what several generations of electricians did to an original system. An inspection in Armatage is usually a question of whether a service sized for a mid-century household still suits one running central air, a finished basement and a car charger. Both are worth doing. They just produce different reports.

Citywide, the balance sits much closer to the Holland end: 68.4 percent of single-family parcels predate 1940 and 78.9 percent predate 1950. Add 10,587 duplex parcels and 963 triplex parcels, where an original system was later split between two or three households, and you have a lot of houses carrying loads and divisions nobody designed for them.
