The minimum for a wheelchair to pass is 32 inches, IIRC. The minimum for a wheelchair to turn 90 degree into a doorway is 48 inches, and the minimum for a 180 degree turn is 60 inches. There are numerous web sites laying these criteria out. If you can do it, 48 inch hallways and 36 inch doors are a very good idea.
When this season first aired in 1993, the original title for this season was The Real World: California. Years later, the season's title was retroactively changed to The Real World: Los Angeles, mainly to avoid confusion with later seasons filmed in California (San Francisco, San Diego, and Hollywood). The show also expanded from 13 half-hour episodes to 21.
The real stars of the film are apparently the locations. Lecce features in many scenes especially the Piazza Del Duomo and many of the narrow streets in the Centro Storico . All the beach stuff is filmed at the Lido Coco Loco at Torre San Giovanni on the Ionian Sea side of the heel.
