ADU Construction in El Segundo
El Segundo ADUs with a roof that sheds water into solid drain lines away from the footings, corrosion-resistant metal and a foundation set by the soils.
Roof water on an El Segundo ADU is planned as carefully as the footings it could undermine. A single-slope roof drains toward one edge, where a gutter and its downspouts collect the runoff and send it into solid pipe. That pipe carries water past the perimeter footing to a drywell or the curb, as the city allows. Soil under the foundation that stays at a steady moisture level helps the slab stay true over time.
Roof shape and the drainage path
Pitching the roof away from the main house keeps runoff off the gap between the two buildings and away from the neighbor's wall. Where a parapet or a flatter section is needed, a cricket behind it moves water toward a scupper so it cannot pond. At ground level the downspout feeds a sealed fitting on a buried line, and that line gets a cleanout where it changes direction. Splash blocks alone are not enough beside a footing, since water landing there soaks the soil the slab bears on.
Metal that holds up in coastal air
Coastal air carries salt that pits bare steel, so gutters and flashing go in aluminum or coated steel, with fasteners of a compatible metal. Under the roof, the ties connecting rafters to walls along with each braced panel's hold-down, are hot-dip galvanized or stainless. Those connectors complete the load path from roof to footing, so a corroded one weakens the whole chain. We note the finish of every connector on the drawings, and the city inspector sees them at the framing stage.

ADU Construction in El Segundo: questions
Concrete sized by the soils report and the engineer. On a firm El Segundo lot that tends to be a reinforced slab with thickened edges. If borings find loose or damp layers, footings go deeper or a mat slab spreads the load. Roof drainage is routed well clear of all of it.
Possibly. In El Segundo we expose the garage footing at a corner, measure how deep and wide it runs and check for cracks. If it qualifies, new sill bolts and shear walls tie the room down. If it falls short, the engineer adds footing sections. Either way, the old garage roof drainage gets redone.
El Segundo units are covered by the package up to 500 square feet, provided they stay on one level. In El Segundo, the roof plan with its slope arrows and drain points goes alongside the site plan in the package, and together they show where water leaves the lot. Bigger or taller designs get a quote after a lot review.
