At this point I'm convinced that it's going to require new regulations to make this happen. The information is not required to be kept open and available on a large scale. There are no repercussions for having an out of date floorplan with the building commission. Neither owners nor brokers have any incentive to put this information online during vacancy because it creates unnecessary work in a market where an opening sells itself. And when that vacancy is filled they have no incentive because they have better things to do.

If you could somehow incentivise tenants, owners, or brokers to update this information when they move in or just before they move out then you could solve this. But I don't think that's going to happen without deep pockets lobbying an addon bill in washington.

Some communities have made rental owners register their properties as rentals. I live in a college town and we have problems with uncut lawns, trash, noise violations. The rental registry is a way to track the actual owner of the property and not the sometimes ever changing occupant.
