About this detail

This assembly details a foundation wall adjacent to an emergency escape and rescue window well. The floor structure consists of floor joists supported by a pressure-treated sill plate, with R30 sound insulation and blocking provided at the rim. The exterior foundation wall is finished with two-coat cement plaster over waterproofing, capped with a stone cap sloped away from the structure. A sixteen-ounce copper weep screed is installed at the base of the plaster. Below-grade waterproofing is applied to the foundation exterior, which includes a four-inch perforated drain pipe set in three-quarter-inch gravel with filter cloth, connected to the site drainage system. The window well includes provisions for a permanently affixed ladder and meets California Residential Code requirements for emergency egress, including a minimum twelve-inch inside width and specific vertical rung spacing.
