Recent houses here do have much larger elevators than houses of 50 years ago, which in turn had much larger elevators than older houses. I don't know if they can accommodate a stretcher but they can often fit a bicycle, which can be quite long. 70 cm of wheel diameter plus tires plus the distance between wheels. It could be close to 2 meters. A stretcher is maybe longer if completely extended. I don't have figures, but my job, but for a multi unit house the extra space is probably not a problem. A typical one could be 10 floors, 4 units per floor. The extra expense for the builder of the house is divided by 40 and the extra space taken from each floor is divided by 4. The maintenance and electricity bills are higher though.
