Can anyone help with a stinky sink drain?

When we unto our kitchen sink to let out water it smells disgusting! Seems to only be one side though. We've cleaned our garbage disposal. We have ground up ice cubes. We ground up citrus peels. Tried the baking soda and vinegar tip. We have tried cleaning tabs bought at store. Everything is just temporary. I think it is like using room spray it just masks the odors for a short time. My husband thinks the piping is not right but our whole house was rebuilt in 2011 even our plumbing and this has only been about a year with this problem. ANY Ideas??
