## Our Process

1. **Plan Review & Code Check** — We review your architect's drawings and confirm all rough-in locations comply with Metro Nashville IPC amendments — including proper vent routing, trap distances, and minimum fixture clearances.
2. **Permit Application** — We handle all plumbing permit applications with Davidson County or the relevant municipality. Turnaround is typically 5–10 business days for standard additions.
3. **Rough-In Installation** — DWV and supply lines are installed per engineered drawings. All penetrations through fire-rated assemblies are properly firestopped per code.
4. **Rough Inspection** — Metro Codes inspector signs off on rough-in before any walls are closed. We coordinate inspection scheduling to fit your GC's critical path.
5. **Trim-Out** — After insulation, drywall, and tile are complete, we return for trim-out — installing all fixtures, making final connections, and pressure-testing the system.

## Frequently Asked Questions

### What's involved in adding a bathroom to a Nashville investment property's basement?

Basement bathroom rough-ins in Nashville require an ejector pump system in most cases because the drain lines run below the main sewer line. The ejector pit receives waste and a sewage pump lifts it up to the main drain line. Code requirements include: properly vented ejector system, check valve on the discharge line, and sealed pit with gas-tight cover. The electrical for the pump must also be coordinated. For Nashville investors adding a basement suite for ADU income, this is a common upgrade — budget $3,000–$5,000 for the ejector system plus rough-in labor.

### Can you coordinate rough-in with framing and other trades to avoid timeline delays?

Yes — this coordination is the critical value we provide for investor clients. Rough-in must happen in a very specific window: after framing is complete and inspected, but before insulation and drywall are installed. We work directly with your GC to identify this window and commit to a specific start date, not a range. We also provide your framing crew with joist boring specifications in advance so they can drill the right holes in the right locations rather than having to fix them later. Botched framing coordination is the #1 cause of rough-in delays on Nashville flips.

## Pricing

$2,500 – $8,000 for rough-in depending on scope, fixture count, and access
