Structural Work in North Hollywood
Foundation, pier and retaining wall repair for North Hollywood houses, reached from the crawlspace or through the slab and permitted through LADBS.
Will the floors have to come up? For a North Hollywood house on a raised foundation, usually not. Footings, piers and cripple walls are reached through the crawlspace or from a trench dug along the outside wall. A slab house is a different case, because reaching a failed footing can mean saw-cutting the slab and patching it afterward. If the lot slopes, walls holding soil are worked from the yard side.
Working from below
A raised floor gives access from underneath. We open the crawlspace hatch, set temporary lighting and bring in shoring posts that fit the clearance. New piers, posts and beams go in while the rooms above stay usable, though a short shutoff of water or power may be needed if lines run where the work is. Bolting the sill and sheathing cripple walls are done the same way. Floor finishes stay in place, and the main thing you notice upstairs is noise during the working day.
When the slab has to open
On a slab foundation, a failed section may only be reachable from above. The engineer marks the cut lines, we saw through the slab and excavate, and new footing and slab are placed under LADBS inspection, since North Hollywood is inside the City of Los Angeles. Flooring over the cut has to be lifted and later replaced, and the quote spells that out. Plumbing under the slab is located before cutting. Jobs in Toluca Lake, Sun Valley or Valley Glen follow that approach and go through LADBS too.

Structural Work in North Hollywood: questions
The structural call belongs to a licensed engineer, who checks tilt, cracking, the footing and whether water still escapes through the wall's drain. Replacing or reinforcing it then requires an LADBS permit for a North Hollywood address, and the inspector sees the footing steel before concrete is placed.
Bearing capacity and depth to firm ground, from a soils report, are where the review begins. The engineer then looks at how the house is supported, raised floor or slab, the state of its footings and piers, any walls retaining earth, runoff patterns and the anchorage of the frame.
Yes for the heavy items: caissons by depth, wall by the foot, piers and posts by count. A North Hollywood quote also lists any slab cutting and floor patching on separate lines, so you can see what reaching the foundation adds before the repair itself is priced.
