Implementing Condominium Restrictions

When faced with a reoccurring issue in a condominium, the Board of the Directors may want to consider implementing a restriction as a long term solution to the problem. For example, after increasing complaints of loud music at late hours, the Board of Directors may consider a restriction as to when and to what extent music can be played at the condominium. Or perhaps unit owners have complained of the increase in short term rentals in the condominium, prompting the Board of Directors to consider a restriction on the amount of times a unit may be rented throughout the year. How are such restrictions implemented?
