Hostel Zoning Information
It is difficult to compile a comprehensive list of worldwide hostel zoning information because zoning laws vary greatly. The easiest way to find out your local zoning information is to search Google for contact information to your local government office and then to phone them.
Every location (country, state, city) has different zoning laws. To find your local zoning board's contact information, go to Google and type something like zoning board [city] and your local government website should be at the top of the results. The site probably won't have specific information about hostels, but if you contact them by telephone, they should be able to direct you to the right department.
