If sufferers of RASH (Regressive Acute Systemic Hypoplasia) are unable to get readopted by friend or family, most end up in a special sort of apartment complex that are exclusively available to RASH victims; any city with any degree of urbanization will have at least one such building, largely because they are quite profitable due to how population dense they are. They provide most RASH victims (any able-bodied enough to move without crawling and with enough mental clarity to be largely self-sufficient, which is most cases)

These RASH Dormitories function much like a college dorm, offering small rooms to 1-2 RASH victims at a time. The rooms are extremely cheap, due to a very small floor-plan, roughly 150ft^2; but since most victims are half the size of normal people, each room is comparable to a 600ft^2 apartment to the tot-sized resident. The doors are only 4 feet tall, and look like little hobbit homes or playhouses to regular sized people, as all the furniture is scaled down, similar to the furniture at a daycare center.

Each dorm comes with a small desk (many get a small laptop or a small custom desktop computer set-up), a little bookshelf, a toddler bed, a foam playmat for a rug, a dresser, and a small chest at the foot of the bed. Most dorms allow for some degree of customizability, and you can opt to have the default furniture taken out, and have custom furnishings… though many are too poor for that option, often affording it by being on a welfare program, usually because of RASH being considered a disability.

To cover the height between a normal hallway and one of the rooms, the design was made into a modular cube of sorts with a lot of the electrical, AC/Heating, water heater, etc components built into an attic above the dorm, along with a large mailbox to receive packages from, big enough for the resident to crawl inside. This also helps keep construction costs down.

In addition to the rooms, the dorms also provide essential goods and services for those living there; a community kitchen/cafeteria with good cheap food, a store that sells diapers for cheap by buying in bulk, and a playground.

———— Bonus: RASH Daycare Centers ————
Within a few major cities around the world, there exist these special Daycare centers for RASH victims who also suffer from MUSH, or are otherwise physically and/or mentally handicapped to the point of needing constant care, and are otherwise unable to get care from friends or family. Such cases that happen elsewhere are often sent to these locations.

These facilities act as Government-run 24/7 Daycare Centers, and are mostly occupied by those who failed or refused to do their mental exercises for too long, or otherwise slipped into a mental state that prevented them from taking care of themselves; they are treated as mental care facilities by law. Many also allow adoptions of such residents, and they are put on a strict daily schedule, not that most of them mind in their babyish mindsets.

The children sleep in rooms with rows and rows of cribs, regardless of age; keeps things simple. The facilities are divided into two major wings - those that aren’t potty trained, mostly toddlers, and those that are, mostly older toddlers and preschoolers. It’s possible a smaller facility may not even bother splitting the two, or even bothering to let those who are potty trained to let them use the toilet and just keep them diapered, but most would be probably humane enough… unless they kept having trouble making it and seemed stuck in that early phase of potty training.

Each facility also has a special Infant wing for those who bounced at infancy, with a higher caretaker to child ratio; though, sadly, rarely are the mentally adapt Infants given much chance to keep their maturity, due to the difficulty of providing such care… plus, such infants are rarely able to do the mental exercises without special inputs. Those rare cases of those with both RASH and MUSH with infantile mindsets, even those with bodies that aren’t infants, would likely be kept here if they were mentally infants and needed similar care.
