How deep do deck footings go on a West Hollywood hillside?

Footing depth on a hillside lot comes from the engineer, who takes each one past loose soil to firm ground, with the low-side posts needing the most. A roof deck has no footings of its own and bears on the building framing. A flat yard can take shallow pads. Plan check sees every depth on the drawings.

What fire rules apply to decking on a West Hollywood parcel?

The parcel is compared with the mapped fire hazard severity zones during plan check, and we look it up before drawing. A mapped parcel calls for ember-resistant boards and a protected underside. An unmapped one is held to the regular building code, with fire-rated decking still available as a choice.

Is a raised deck in West Hollywood priced by height or by area?

Each changes different lines. Area sets the decking, joists and guard length. Height sets posts, bracing and footing depth. A deck over a room adds membrane, drains and pedestals. We break the quote into those groups so you can see what a change in size or height does.

West Hollywood Decks & Patios, Guards to Footings

West Hollywood decks and patios drawn for plan check: guard anchoring, stair geometry and waterproofing for upper-level decks, with engineered footings.

Guards and stairs draw close attention from a West Hollywood plan checker, because they are the parts people lean on and walk down every day. The drawings have to show guard height, the size of any opening, how each guard post is anchored and the rise and run of every step. We detail those first. Footings and framing follow, and if the ground drops away, an engineer sizes the posts and bracing.

Guard posts and stair details

A guard post bolted to the outside of a single rim joist can pry loose under a hard push, so the drawings show blocking and hold-down hardware that ties each post into the joists. Openings between balusters are kept small enough that a child cannot pass through. Stairs need even risers, treads deep enough for a full foot, a handrail a hand can grip and a landing at the bottom. Cable or glass infill is possible, and the set then shows the tensioning or the panel rating.

Decks over living space

A deck may sit on a roof or over a room. There the reviewer looks past the boards to the membrane beneath, the slope that carries water to a drain or scupper, and the way the deck load reaches bearing walls below. Sleepers or pedestals hold the deck boards above the membrane so it can be inspected and replaced. The building department may also ask for a structural review of the existing framing. Ground-level patios skip most of this and are reviewed for any wall, cover or gas line built with them.
