On an inland valley lot, the strip of lumber resting on top of the foundation wall takes more wear than most parts of a house. Hard sun dries the framing above it, dry wind pulls moisture out of the crawlspace, and a rare heavy storm soaks the soil along the footing. In Panorama City we treat that sill, and the bolts through it, as the first link carrying an earthquake load down to the ground.

How the sill gets tested

We move along the sill line on hands and knees, pressing an awl into the wood as we go. Sound lumber resists the point, while a soft patch gives way where water once sat against it. Each existing bolt is checked for a washer and a snug nut, and the gap between neighboring bolts goes onto a floor sketch. Where the plate has split or the concrete beneath it has spalled, new anchors land beside the damage. Decayed sections come out, and pressure-treated plate goes in their place before fresh hardware is installed.

Plan check for Panorama City and its neighbors

Panorama City is inside the City of Los Angeles, so plan check and field inspections come from LADBS. Bolting plus cripple wall bracing on a raised floor may qualify for the standard plan. A cut bearing wall or a new beam calls for drawings and calculations from an engineer. Arleta, North Hills, Van Nuys, Valley Glen, Mission Hills and Pacoima answer to that same office, and each permit there is set up the same way before work begins under the floor.
