Why isn't there better housing for the elderly?

I know this would be better posted on a housing-contractors' or property developers' forum but you can't post on any of their forums without a license--I have posted it on a realtors' forum--so here goes with putting it here & if anyone on here is able to & feels so inclined to pass it on to any contractors or property developers, that'd be great.

There need to be more housing tracts/subdivisions built with the elderly in mind. In my area & I think most areas, the housing for the elderly consists of mobile home parks--which my husband for one would never agree to live in & it's true that with the 9 mo. of summer we get around here, it's like living in a metal & glass box plus you don't get much of a yard--or apartments in senior housing complexes or condos. (A few of the complexes have detached cottages but they're not very big.) And the space rent for both the MH parks & complexes and the Homeowners Assn. fees for the condos keep going up, up, up and none of those places usually offer a garage, usually just a carport if you're lucky.

You might get lucky & find that cute little "4-leaf clover" house (one that's just big enough, just a big enough yard, a garage & in a good enough neighborhood that you won't have to worry about lowlifes), but around here? Expensive as all get-out & all the realtors around here have lonnnnng waiting lists for houses like that; when/if they do get a house like that, they don't even have to advertise; all they do is list it & start calling the names on their waiting list & usually have a sale just a couple days later.

So they finally built a new housing tract in our town that they said would be a "new but old-fashioned" kind of tract: not-big but not-tiny, row houses with garages around a nice common area where you have a cute little back yard & people nearby enough you could get to know & maybe even get help from your neighbors if need be (which is what the elderly need) like the good-old-days small-town living. Sounds great, right? Wrong. They built all the houses 2-story. So they might as well have put a sign up, "Not For Any of You Old Folks; Young Stair-Climbers Only."

So it would be smart & the decent thing to do for more developers to build tracts with old-fashioned housing as described in the paragraph above but ONE-story since not all of us elderly can afford or want to live in mobile homes or apartments or condos or a room in their kids' house (if they've even got any kids; not all of us do). I think you developers are missing out on a real opportunity with this with the amount of us elderly baby boomers.
