Structural Work in Woodland Hills
Structural work in Woodland Hills for ADUs, garage conversions and additions: lot records, engineering, LADBS permit, shoring, footings and framing.
Pulling the permit history and the hazard maps for a Woodland Hills lot is the opening step of any structural job we take on, whether it serves an ADU, a garage conversion or an addition. An engineer then sizes footings, beams and posts from that record and the planned load. Once LADBS issues the permit, temporary shoring carries the floor or roof before a bearing wall is cut. Footings are dug, inspected and poured, then framing and hardware go in to the stamped sheets.
Garage slab before garage walls
Before a Woodland Hills garage becomes living space, the slab gets a close look along its edges, where any footing would sit. We dig beside it or drill a small hole to learn its depth and whether a moisture barrier lies underneath. A slab with an adequate perimeter footing can stay, finished with a vapor-retarding coating and a raised floor if the room needs one. A thin or cracked slab may need a new footing under the walls or a full replacement, and since that choice reshapes the whole scope, it is settled before layout.
What each ADU type asks of the ground
A detached ADU stands on its own new foundation, either a slab on grade or a raised floor over a perimeter footing, sized for the soil and the load. An attached unit or an addition ties into the house, so its footing is doweled to the old one and the floor heights are matched. A JADU stays inside existing walls and seldom needs foundation work, though removing a wall may still call for a beam. If the soil is expansive or the lot slopes, the engineer adjusts depth and reinforcing, and we price that change before you commit.
Structural Work in Woodland Hills: common questions
It might. The answer turns on the slab's thickness, whether a footing runs beneath the walls that will enclose the new room, and whether moisture rises through it. We check those points at the start. A sound slab can often stay with a vapor-retarding layer above it, while a thin or cracked one may need an added footing or a new pour.
Whenever a load path changes. That covers removing or shortening a bearing wall, adding a second story, setting a new foundation for an ADU, and most footing repairs. LADBS reviews the engineer's calculations and stamped sheets with the permit set, and we build to those sheets and line up the engineer's site visits as the work goes in.
It can. The City of Los Angeles may call for a soils or geology report depending on the lot and the project, for example a new foundation on expansive soil, a lot that slopes, or a site inside a mapped landslide or liquefaction area. We look this up during the lot review and bring in a soils engineer when one is required.
