How many people can legally live in a one bedroom apartment in the USA?

In the USA, the number of people who can legally live in a one-bedroom apartment typically depends on local housing codes and regulations, which often stipulate occupancy limits based on the size of the unit. A common guideline is two people per bedroom, plus one additional person; therefore, a one-bedroom apartment may legally accommodate up to three people. However, local laws can vary, so it's essential to check specific regulations for the area in question.
