My last house didn't. Every major appliance used natural gas. Most prewar homes don't have 220v either unless it was added later (commonly as part of an air conditioner installation, but even then, often the AC unit has the only 220v circuit). It's not hard to add 220v to an existing home, but it is less common than you think. Before electric cars existed, the main reason a homeowner would add 220 was for air conditioning, large stationary power tools, or if they were one of those weirdos that preferred electric stoves to gas (before induction existed).
