Moving to adopt

Good morning! My husband and I are excited to start the adoption process and are moving to have a house with more bedrooms for part the home study. While we are familiar with other criteria to look for in our home search, our realtor mentioned checking the sex offender registry for any that live nearby. I haven't heard that stipulation before and it is proving to be difficult to find a neighborhood without a few people on that list (we live in a more populated area outside a city). Is this something that will truly fail our home study?
