As I'm approaching the 1yr anniversary of the purchase of a home in NC (constructed in mid-2005), I hired a local inspector to provide an independent assessment of the condition of the home. The builder's warranty expires on July 10th.
One thing the inspector did not check was the performance of the bathroom fans...he checked to see that they worked but did not have an anemometer or other meter required to measure air flow.
What is the code requirement of sizing of residential bathroom fans (I'm guessing 1-2 cfm fan size per sq ft but the ceiling height in the bathroom is 10' so there's lots of volume here)? Our master bathroom fan does not keep steam from forming on the mirrors and clearing the mirrors and shower doors of steam takes 15-20 minutes after finishing the shower.
I've summarized the punch list for the builder with some photos at

I hired an inspector based on the advice from this forum...too bad I didn't do so when we purchased the home last year. If you see anything on the list or if I've said anything that is no accurate please let me know.
As to the fan, I have a meter to test it with later this week. Steve D
