Bathroom or ADU work in LA or OC? Check the sewer cleanout before demo

On Los Angeles and Orange County bathroom remodels and ADU conversions, sewer access can decide whether rough plumbing stays simple or turns into a bigger repair. Older homes may have buried cleanouts, patched drains, root intrusion, cast iron sections, or fixture layouts that were never reviewed for the new bathroom, laundry, or kitchenette plan.

Before demolition, confirm where the main cleanout is, whether it is accessible, which drain lines serve the room, how the new fixtures tie in, and whether the existing sewer line should be camera inspected before concrete or tile is removed. For garage ADUs and estate homes, also check slab penetrations, drain slope, vent routing, water shutoff access, and whether plumbing changes need to be included in the permit instead of handled as a simple fixture swap.

The practical sequence is fixture layout, cleanout location, sewer and drain review, permit scope, demo, rough plumbing, inspection, then waterproofing and finishes.
