The Bathroom Venting Rule That Prevents Mold
Your bathroom exhaust fan does more than remove odors—it removes moisture. But if that moisture isn't properly vented to the exterior, it can create serious problems inside your home.
Building code requires bathroom exhaust to vent outside, not into an attic. Improper venting can allow warm, humid air to collect in the attic, leading to condensation, mold, and damage to the building structure.
This is an often-overlooked detail, especially in older homes, but it's an important part of designing a healthy, durable home.
