Check Metros web site. They have a ink where all sex offenders must register. Keep in mind not all of them register.
As such there are other measures you can take when looking for a home to buy and or rent.
In most places the law prevents sex offenders from living within 1,000 feet of a school and 1,000 feet of a playground. This is in addition to having to register.
Nothing is 100% certain but its one more tool in your bag to keep your children safe.
Let me know if I can be of any future assistance.
