Your local housing administration will have that information available in most areas. If not you can visit the county clerk for up to date information.
You should check with your local Public Housing Authority; they usually keep a voluntarily list of properties, whose landlords will accept Section 8; but remember this list is not comprehensive.
The Housing Authority in your area should be able to give you a list of Section 8 approved housing, or direct you to the party that administers the program.
