Bathroom Remodeling in Woodland Hills
Woodland Hills bathroom remodels and compact ADU baths built in a fixed order: framing repairs, rough plumbing, inspection, waterproofing, then tile.
Framing repairs come first in a Woodland Hills bathroom. Once the old tub and tile are out, any soft subfloor or notched joist under them is fixed before a single new pipe goes in, since a drain needs solid wood to hold its slope. The plumber and electrician rough in next, LADBS inspects the open walls, and waterproofing and tile start only after that inspection passes. A compact bath inside a new ADU follows the same order.
Behind the walls, in sequence
With the room down to studs, the plumber sets new drain, vent and supply lines while the electrician runs circuits for the lights, the outlets and the exhaust fan. Outlets beside the sink are ground-fault protected, and the fan duct is carried all the way through the roof or an outside wall so damp air leaves the house. The new piping is tested under pressure and left exposed for the rough inspection. Insulation and backer board stay stacked aside until the inspector signs the card, because a closed wall cannot be checked without tearing it open again.
One waterproofing method, then tile
Shower walls get a single waterproofing approach. Cement backer board is screwed to the studs with no plastic sheet behind it, and its face is coated with a liquid membrane brushed into every corner over reinforcing fabric and lapped down onto the shower pan. Two separate barriers would trap moisture between them, so the board carries only this one. The finished pan and membrane are flood tested for a day to prove they hold water. Tile, grout and fixtures go in after that, and LADBS makes its final visit once the toilet, vanity and fan all work.
Bathroom Remodeling in Woodland Hills: common questions
It can. Under California's JADU rules the junior unit may use a bathroom in the main house when an inside door connects the two living spaces. If a private bath might be added later, a remodel is a sensible moment to run drain and vent lines toward that corner of the house, so the floor does not have to be opened a second time.
Every fixture gets a drain, a vent and hot and cold supply. Drains need a fall of about 1/4 inch per foot so waste moves to the sewer connection, and whether the unit ties into the house line or runs its own is settled when the plans are drawn. The water heater has to keep up with an extra shower. It is all inspected before the walls close.
Yes. When the old tile and backing come off, we probe the subfloor around the toilet flange and the tub, look at the bottom plate under the shower valve, and take moisture readings on the studs. Anything soft or stained is photographed and explained to you, and its repair is added to the scope before new material covers it.
