Is there any requirement that the owners of these dwelings have a Range, Disposal, Dishwasher, etc... installed after they purchase these units.

That's kind of like making some one buy a Cadilac when all they wanted to buy was an Impalla.

If someone roughed in for a Central Air, yet they discovered the house would be cool all Summer without it, so they decided not to purchase and install the Condensing unit, would they never get a final?
