New homes in the US may not be “electrical ready” after an international standards agency excluded building electrification measures from its latest energy code.
You can’t say for sure. My house has a gas stove and a 220v outlet for an electric stove. Most houses are wired for an electric stove even if it has gas, because not everyone is going to want a gas stove and wiring an outlet is easier than running a gas line.
If the kitchen was made for gas, it’s pretty unlikely there is a 220v outlet for an oven there.
