William Floyd Martin, 47, is accused of sexually abusing a teenage girl numerous times between 2003 and 2009.
The victim, who is now in her early 20s, said the illegal sexual contact took place at Martin's home.
She contacted the Ada County Sheriff's Office earlier this month to report the crimes. Deputies spent the past week gathering evidence.
Deputies arrested Martin without incident as he left his home Friday morning. He was taken to the Ada County Jail, where he was charged with lewd conduct with a child under 16.
He is scheduled to make his initial appearance in Ada County Court on Monday.
If convicted, Martin could face up to life in prison.
