Toilet Repair in Darien, IL
Darien has old housing and a mixed tenure: 77% of homes predate 1990, and 21% of households rent. Which of those you are changes the whole answer.
Short version
In Darien the split runs 79% owner-occupied against 21% rented. That makes responsibility a matter of your own address rather than the town's pattern, and it is worth settling before anybody is called out to the property. With 77% of the housing built before 1990, a fixture predating the 1.6 gallon standard may still be in place; the figure describes the building rather than the bathroom.

What the age of Darien’s housing suggests
77% of housing units in Darien were built before 1990, which is to say before the Energy Policy Act of 1992 set a 1.6 gallon maximum. EPA puts pre-standard fixtures at 3.5 to more than 5.0 gallons a flush.
That is about the house, not about your bathroom: a 1968 home may be on its third toilet. What the figure says is that in a town like this, an original fixture is a live possibility rather than a curiosity.

What is actually wrong with it
Start by naming the symptom precisely, because the four common ones have nothing in common mechanically. A tank that never stops refilling, a handle that does nothing, water appearing at the floor and a flush that needs two goes are four separate repairs.
If you are quoted for a new fixture, ask what ruled out the parts. Flappers and fill valves are inexpensive and account for most of what goes wrong, so replacing the toilet without testing them has skipped a step.
