@SgtEasy lol where in the series are you? I'm a TWD addict, lol
Legally they have to be, but by code that only means that hallways and doorways have to be so wide, counters can't be higher than a certain level and so forth. (Varies by state) - but having said that, older buildings are grandfathered in and don't have to be. From the image Khalessi provided, I would say no, they aren't.
Way around that, your building is the new one across the street, so it would be. So that leaves an option to see if someone can talk Claire into crashing with Tas so Echo can crash in Claire's room while she recovers.
