Lake View Terrace Decks & Patios, With the Stair Worked Out First
Decks and patios in Lake View Terrace planned with the stair down to the yard, its landings and footings, ember-rated treads where mapped, and LADBS review.
Where will the stair reach the yard, and how many steps will it take? We answer it on the first Lake View Terrace walk-through by leveling out from the door sill and reading the drop along the path the stair would follow. If the yard falls away, the stair keeps chasing the ground, so its foot lands farther out than a sketch suggests, on a landing pad with a footing of its own.
Rise, run and a landing partway down
Total drop divided into equal risers sets the step count, and each riser adds a tread to the run. A single flight may climb no more than 151 inches between landings, so a tall stair on a falling yard gets a landing partway, which needs posts and footings too. Treads and risers must stay uniform within a small tolerance from top to bottom, since an odd step catches feet. A handrail is required once a flight has 4 or more risers, and the open sides take guards wherever the drop beside the stair calls for one.
LADBS review for a deck and its stair
Plan review and inspections run through LADBS, since Lake View Terrace lies within the City of Los Angeles. The permit set draws the stair in section, with rise, run, landing and handrail dimensioned, beside the engineer's post and bracing design for the deck. Footings for the stair and landing are inspected open with the deck's, and at final the inspector can put a rule on the risers to confirm they match. On a lot with grade, the bracing is compared with the calculations. Some parcels in the area also appear on the state fire hazard maps, which can bring the stair under ember rules along with the deck.

Decks & Patios in Lake View Terrace: questions
The soils report gives each footing a depth, and the drill has to prove it. When the auger strikes cobbles or a boulder short of that mark, the hole is cleared by hand or with a heavier rig until it gets there, since one stone says nothing about the soil around it. Footings under the stair and its landing are held to the same standard.
The fire rules reach past the deck on a mapped Lake View Terrace parcel. Stair treads, risers and landings close to the house fall under the same decking section, so they take the same noncombustible, ignition-resistant or tested material as the boards. The inspector can also ask that the space under the stair stay free of stored wood and leaf litter. LADBS plan check confirms the parcel's status.
Height reaches into the stair as well as the frame. Under the deck it buys longer posts and more bracing, and down to the yard it adds treads, longer stringers and more handrail with each step of drop, plus a landing past the single-flight limit. Width and depth add framing, decking and guard rail. Setting the deck a step below the door sill trims both.
