How many students can dorm at uc Berkeley?

UC Berkeley doesn't publish a single number for how many students can dorm on campus. The number varies each year depending on renovations, new construction, and the overall student population. Instead of a total number, UC Berkeley provides housing guarantees for certain student groups (typically first-year students) and then offers housing on a lottery or space-availability basis to upperclassmen. Therefore, there's no fixed answer to your question.
