Structural Work in Hidden Hills
A thin or cracked footing under an older Hidden Hills house changes a retrofit. We find it, an engineer draws the repair, and it is inspected open.
Dig beside the foundation of an older Hidden Hills house and one stretch of footing may turn out shallower than the rest, or cracked clean through below a corner window. From inside, that shows only as a stucco crack that comes back after every patch. Finding it changes the job. Bolting alone will not do, an engineer draws a new length of footing, and the anchors at that corner go into fresh concrete.
Finding a weak footing
The survey runs along the inside face of the stem wall with a light, a hammer and a level. Concrete that crumbles at the surface, a crack that steps down through the wall, or a section sitting lower than its neighbors gets a chalk mark and a photo. Where a footing looks thin, we dig a small test hole outside to find its bottom edge. Each mark goes onto a plan of the foundation. The engineer works from that plan, and underpinning or new concrete is priced only for the lengths that need it.
Fire maps, vents and inspection
Mapped fire hazard zones cover parts of Hidden Hills, and a lot inside one may face ember-resistance rules when foundation vents are changed during the work. Listed vents with a fine metal mesh keep embers out and still let the crawl space breathe. The building department that serves Hidden Hills inspects the trench and reinforcing steel before concrete goes in, then the bolts and plywood before the crawl space is closed. Upstairs, oak floors, plaster and window casings are left in place, since every step is reached from below or outside.

Structural Work in Hidden Hills: common questions
Walk the outside first. A stair-step crack in the foundation, stucco that splits again at the same corner, or a gap opening under the sill all point to a footing that has moved. Inside, look for doors that now bind where they once swung free. The crawl space then shows whether anchor bolts and bracing were ever added.
A permit, yes, from the building department that serves Hidden Hills. An engineer handles new footings, beams and any change to a wall that carries load, sizing the concrete and steel for each. Plain bolting and cripple-wall bracing on sound concrete may use a prescriptive plan without engineering. The test holes tell us which path a house is on.
In most cases. Footing repair is reached from outside and from the crawl space, so the rooms above stay closed up. Breaking out old concrete sends vibration through the house, so we photograph plaster cracks before work starts and again after. If a wall must open for a beam, casings come off by hand and are rehung on the same wall.
