Apartments, just as the interior of houses, and areas such as the Solar in the Waking Sands/Rising Stones, are actually shared spaces that simply display different things for different people.
This is why:
1. The Solar has 'instances', i.e. "You are in Instance (1) of The Solar." so that on expansion and patch launches, the zone doesn't get congested.
2. Housing has become congested in the past, namely on EW's launch where loads of people were camping out in their houses with autoclickers to avoid the AFK timeout.
In both cases, too many people in those areas will cause them to become 'full' and not allow any more people in. Yes, you could try to enter your house and it would say "This zone is congested".
So houses, and apartments, and indeed any form of instanced housing that uses the same system, would be susceptible to congestion and be limited in number. Thus it doesn't solve anything, it would be the same as providing more wards, and still require additional server capacity.
