A self draining door sill assembly for use in the bottom of an exterior door frame of a house or other building is disclosed. The assembly includes an elongated base and a threshold member adjustably attached to the base for cooperating with and engaging a weather strip attached to the underside of a door when the door is closed in the frame to form a primary water seal. The threshold and base define an elongated water chamber therebetween and the threshold defines an upwardly opening storm drain channel formed in and along an upper, interior side surface portion thereof which terminates in a pair of slots located in opposite ends of the threshold, which slots also communicate with the underlying water chamber. A pair of spaced apart weep channels are formed in the base and extend from a floor of the water chamber exteriorally along the through an exterior side of the base, such that rain water which blows or seeps past the primary seal gathers in the drain channel, flows through the slots onto the floor of the water chamber, migrates along the floor to the weep channels, and then flows through the weep channels out of the assembly. A weather cover panel covers an exterior side portion of the base and a compressible resilient gasket is attached to the weather cover and fills a gap between the weather cover and the threshold member.
