Room Additions in Sherman Oaks
Sherman Oaks room additions with upstairs laundry or bath floors framed for vibration and weight, drawn for LADBS review.
A washing machine in full spin shakes a floor in a way a bed never does. If a Sherman Oaks addition puts the laundry or a bath upstairs, the floor beneath has to carry that vibration plus the weight of a tub and its water. Joists get deeper, blocking gets tighter, and the plans describe it before the first board is cut.
Framing for machines and tubs
A tub full of water weighs far more than the furniture a bedroom floor is sized for. Framing under a bath uses deeper joists or doubled members, with blocking to spread the load. A laundry floor gets a stiff subfloor, glued and screwed, and a drain pan with a line to the outside. Plumbing runs through the joists in drilled holes the engineer approves, so no framing is notched away at the points that carry the most. Sound-rated insulation in the floor cavity quiets the room below.
Review at LADBS
A Sherman Oaks address falls under the City of Los Angeles, and LADBS reviews the permit set for it. Reviewers read the floor framing, the bearing walls below and the footing under them. If the new floor rests on old walls, the plans show how load travels down through them. Inspectors check framing, plumbing and the link to the old house before drywall goes up. In the written quote, the heavier framing sits on its own line, so the cost of an upstairs choice is visible.

Room Additions in Sherman Oaks: questions
The old footing's size, depth and bars are measured against the combined load of the new floor, a tub and the walls above. A passing footing carries the upper story as it is. A short one gets added sections or posts, which we build first.
New joists bear on the old walls or a beam, with a ledger bolted at the floor edge. Hold-downs and straps pull new studs and old together. The roof joint is flashed, and plumbing and wiring runs are planned so the framing keeps its strength.
With the crawlspace open for the new footing, the sill bolts and short walls are within reach. That work shares the addition's drawings and its inspection round, so the added effort is small. The quote lists the retrofit apart from the new room.
