Windows & Doors in North Hollywood
North Hollywood door and window openings flashed with sloped sill pans so water never reaches the mudsill and anchor bolts that hold the house down.
Mudsill rot under a leaking threshold is how a North Hollywood door can quietly weaken the grip the house has on its foundation. The sill plate is the board the anchor bolts pass through, and when water from a door soaks it again and again, the wood around each bolt turns soft. In a quake that bolt can tear free. Keeping water out at the door protects that connection as much as the floor.
A sill pan that sends water back out
Before the door goes in, the rough opening gets a pan that covers the framing at the bottom, with end dams turned up at each side and a back dam on the room side. The pan slopes slightly outward, so any water that gets past the door's own seals drains to the exterior. Side flashing laps over the pan, the head flashing laps over the sides, and the building paper above laps over the head. Outside, the patio or walk is kept a step lower than the threshold and pitched away from the wall.
When the wood is already soft
During demolition we probe the sill plate and rim joist under the old door. Sound wood stays. A soft section gets removed and a new length of pressure-treated plate goes in, tied back to the foundation with fresh anchor bolts or retrofit plates per the engineer's detail. If the rot reaches the studs at the door's sides, those get replaced as well before the header goes back. The repair goes on the LADBS permit for the opening, so that work is open for inspection before anything hides it.

Windows & Doors in North Hollywood: questions
It can, with a header for the wider span and a threshold that drains outward. Everything under the old sill is cut away, and posts take the header load to the floor framing. North Hollywood falls under LADBS, which reviews the change, and the engineer decides whether the wall's bracing needs replacing.
Sizing starts with the span and with what rests on the wall. A beam under roof only can be lighter than one carrying a floor or a girder. The engineer picks solid sawn, engineered wood or steel, then specifies the posts and the hardware connecting each end to the framing beneath.
Most of it does. LADBS handles permits in North Hollywood, as part of the City of Los Angeles. Resized openings need structural drawings, and replacements are checked for energy labels and tempered glass. Any mudsill or anchor repair found under a door is added to the same permit.
