The easiest way to find out if you need a permit in order to have your alarm system monitored is to call your local Police Department or Sheriff's Office. They'll be able to tell you the most current requirements if there are any.
Another option is to check their website which will often have a part on alarm systems and policies regarding them.
If you wish, you can also search your city or municipal code (many of these can be found online) for "burglary" or "alarm". The section on alarm systems will state whether a permit is or isn't required by your local ordinance.
