Our office has the same issue. The problem is, the code only talks about number of employees but not proportional allocation between genders. It's possible that they have 200 men but less than 230 employees. This means they need 8 waterclosets, but naturally the builders made 4 for women and 4 for men. It's up to code, but don't expect to always be able to use the bathroom at work.
