We prepared and reviewed a plumbing rough-in estimate for a multi-unit residential property.
The underground plumbing phase — including building drain, sewer, and below-grade branches under the slab — was already completed. This scope covers the above-ground plumbing rough-in (also known as “top-out”).
Scope of Above-Ground Plumbing Rough-In Includes:
10 toilet rough-ins
10 lavatory sink rough-ins
4 kitchen sink rough-ins
4 shower stall rough-ins
2 tub/shower combo rough-ins
4 dishwasher drain and supply connections
4 laundry washer boxes (hot, cold, drain, vent)
2 water heater rough-ins
During the top-out phase, all water supply lines, drain lines, and vent systems are installed within the framing before drywall. Proper slope, venting configuration, pipe sizing, and fixture spacing are critical to meet Los Angeles plumbing code and ensure long-term system performance.
Accurate layout at this stage prevents costly corrections later and ensures smooth inspection approval.
