For the purposes of canon, Claudia died sometime in 2004. It is currently November of 2011 in Beacon Hills, meaning she died a little more than 6 years ago.

The Hale fire has been established as happening 6 years before the start of the show - the first episode took place in January of 2011 TWT (Teen Wolf Time). Meaning we've passed or are approaching the 7th anniversary of the Hale House Fire.

As to any connection between the two - The Hale House Fire was caused by Kate Argent and a group of human conspirators. There was no apparent connection to the supernatural other than the fact that the target of the conspiracy was a family of werewolves.
