Additions and remodeling in El Segundo, Los Angeles County

Home additions in El Segundo

In an El Segundo second story addition, the seam where the new floor meets the old roof gets the most care: lapped flashing, kickouts and coated connectors.

Where a new upper floor meets the old roof line, the joint is the part of an El Segundo addition we watch most closely. Close to the water, moist air and wind-driven rain find any gap in flashing, and a second story adds many new joints at once. That joint is lapped, sealed and inspected before siding goes on, so the bedrooms added for a growing family stay dry and the rooms below stay undisturbed.

Joining the new floor to the old

Before framing starts, the existing roof is opened only over the area being built, and tarps cover the rest overnight. New floor joists sit on the existing walls or on new beams the engineer specifies, and the old ceiling stays in place below as long as possible so the family can keep sleeping downstairs. Step flashing runs up each wall where a lower roof meets the addition, with kickout flashing at the bottom to throw water clear of the siding. Stainless or coated connectors are used throughout because ordinary steel rusts fast in damp air.

Permits from the city

El Segundo has its own building department, and its plan check covers the structure, the energy design and the height and setback limits that set how big an upper floor can be. If the lot falls inside the state boundary for development along the water, a separate sign-off may come first. Homes in nearby Manhattan Beach and Hawthorne go through their own city reviews on similar drawings, and the build is staged the same way, with the stair location settled early so the ground floor keeps working.
