For a small fee you could find out neighborhood statistics online, sites like www.Intelius.com, NeighborhoodScout.com, www.RegisteredOffendersList.org, Or you could probably call the fairfield police station and ask them the same question. Also if you are uncertain about living in that area, drive by it at different times of the day and ask yourself is this somewhere where I want to live. If you have any more questions regarding real estate in Fairfield feel free to contact me. Ryan Vivo, Realtor, Gateway Realty. 707-384-5894.
