Though not officially listed as places for housing, some small businesses and homeowners supplement their incomes by offering space for rent in an empty room or annex. Some landlords hold tenants to strict rules in their makeshift dwellings, while others, as long as they get their money, give renters carte blanche.
One such arrangement, a solarium for rent on the rooftop of a downtown laundry, belonged to the crazed Doctor Axolotl, inventor of the M.E.L. robot. Axolotl paid to keep the glass-ceiling room for his own purposes, converting it into a laboratory where he could work on his automated assistant in relative peace and seclusion.
