Yes. We have looked into that whole issue. I could probably follow up with the exact cost that we came up with, but generally speaking, what we're concerned about is that too many requirements are being loaded onto a homeowner. They would have to incur those costs before selling, which then is a disincentive to sell the home.
For example, if an older person is living alone in a large house and they want to downsize, they are faced with the cost of having to do some kind of retrofit before the sale. We have taken the position for a long time that we don't want that kind of regulation, because it will stagnate the market and prevent people from moving.
As Mr. Dufort pointed out, when you have movement in the housing spectrum, it frees up other units, so that's desirable.
