Also one other item to note is that the FCC’s regulations are not meant to supplant any existing State Laws requiring MLTS e911. So although the FCC may give you a year, depending on your location you may already have some requirements to provide the specific location of your phones.
For example in Michigan varied (based on size and type of facility) MLTS e911 “dispatchable location” requirements are going into effect this month, they won’t start fining until the end of the year, but once again… CYA… who wants to do an install or configuration twice.

Over 20 other states have similar requirements already.
Alaska, Arkansas, Colorado, Connecticut, Florida, Illinois, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, New Hampshire, Oklahoma, Pennsylvania, Tennessee, Texas, Utah Vermont, Virginia, Washington . All have various laws.
