What kind of foundation does an ADU in Woodland Hills sit on?

Woodland Hills ADUs on firm, level ground generally get a slab with a thickened perimeter carrying the walls and parapets. The engineer sizes it for roof and wall weight and adds depth where hold-downs bring large uplift. A soils report, when needed, can change the width or the depth.

Can a garage in Woodland Hills be converted without new footings?

If the garage walls sit on a continuous footing of useful depth, new anchors and hold-downs may be all the base needs. A flat roof added during the conversion brings new weight and new bracing, so we check the footing against that before the design is settled. Thin edges get new footing sections.

Which ADUs in Woodland Hills does the plans package cover?

Coverage runs to 500 square feet on one floor for a Woodland Hills ADU in any of its forms. Here the framing sheet carries the roof plan with its scupper and overflow positions. Two-story or bigger units get a separate review and their own quote.

Rain on the nearly flat roof of a Woodland Hills ADU still has to reach an edge, and with a parapet around it that edge is a scupper cut through the wall. Tapered insulation or framing gives the deck its fall, and the parapet itself is braced back to the roof joists so it does not fold outward when the ground shakes. Rain and seismic load meet in the same short wall.

Scuppers and an overflow

Each primary scupper empties into a leader head and a downspout that carries water to the ground. A second opening set a little higher through the same parapet serves as the overflow, so a clogged leader cannot let water pond deep enough to load the framing. The membrane wraps through each opening and up the inner face of the parapet, and a metal cap closes the top. Leaves and grit are what block a scupper, so we place them where a ladder can reach for cleaning.

Bracing the parapet

Unbraced parapets are among the first parts of a building to fail in strong shaking. On a small unit, a short parapet framed as a continuation of the wall studs, with blocking and straps tying it to the roof joists, stays put. The engineer also checks that the roof sheathing is fastened to the walls along every edge so the roof works as a single diaphragm. LADBS reads those connections on the framing details, and the inspector looks at the straps before the parapet is covered.
