What has to happen before an addition can start on a Woodland Hills lot? Three things come first: a soils report that says what the ground will carry, a survey of where the house sits against its property lines, and a route for lumber and concrete to reach the back of the lot. With those in hand, the drawings go to LADBS for plan check, since Woodland Hills is a neighborhood inside the City of Los Angeles.

Footings for a new room

The soils report sets a bearing value, and the engineer turns it into footing widths and depths. Where the addition meets the house, the old footing is exposed and measured, and steel dowels are set into it so the two pours behave as one foundation. If the ground drops across the footprint, the foundation can step down in level runs or carry the floor on grade beams between drilled piers. Shear walls and hold-downs in the new framing follow the structural sheets, and an LADBS inspector signs off the open trenches before any concrete goes in.

A deck that stands tall

A high deck is a structure in its own right. Posts are sized for the height they span, braced side to side with knee braces or a steel frame, and set on piers drilled to the depth the engineer specifies. Beams cross the posts and carry the joists, and the ledger at the house is through-bolted to a rim joist we have opened and confirmed sound. Lateral connectors tie the deck floor back to the house framing, guards are built to take the push of someone leaning on them, and the stair lands on its own pad. Plans for Tarzana, Winnetka and Canoga Park pass through that same city plan check.
