Columbia SC Plumbing Permit

Pulling Plumbing Permits in Columbia and Richland County

Columbia and Richland County run centralized, automated permitting systems — a step up from some of the smaller SC jurisdictions where you're still filling out paper forms. The tradeoff is stricter documentation requirements at the application stage.

Before you can pull any permits here, you need your state contractor license (LLR pocket card), a local business license, and registration in the county's online permitting portal. Missing any of these three means your application gets rejected before anyone reviews the project details.

eTrakit Online Portal

Richland County requires all licensed contractors to apply for plumbing permits through the eTrakit online portal. The application must identify both the licensed business entity and the qualifying licensee by name and license number. You'll also need:

• A Tax Map Reference Number for the work site
• A detailed fixture list with the application
• A copy of the executed contract (for City of Columbia permits specifically)

The City of Columbia additionally requires LLR registration verification as part of the business license application — the city cross-checks your state license status before issuing the local license.

Permit fees are based on total project valuation rather than a per-fixture rate. This means larger renovation projects will carry proportionally higher permit costs compared to jurisdictions like North Charleston that use flat fixture-based pricing.

Inspection Sequence

Richland County enforces a structured residential inspection sequence:

1. Plumbing under-slab — all under-slab piping must be visible before concrete placement. Pouring concrete before this inspection is approved is a code violation.
2. Sheathing inspection
3. Framing rough inspection
4. Electrical rough inspection
5. Mechanical rough inspection
6. Plumbing rough inspection — DWV systems must pass pressure testing per IPC Section 312 before any wall covering goes up.
7. Final inspection — all fixtures operational, water heaters and backflow preventers installed and tested.

The key rule: concrete slab placement is prohibited until under-slab inspections are approved. Starting the pour early doesn't just risk a failed inspection — it can require the contractor to break out and redo the slab at their own expense.

Re-Inspection Fees

Richland County uses a structured penalty scale for failed inspections:

• First re-inspection: No additional fee
• Second failure (same request): $30.00
• Third and subsequent failures: $50.00 each

This escalation is designed to discourage contractors from using inspectors as a free QA check. Get your pressure tests right before calling for the rough-in inspection — the $50 re-inspection fee on a third failure adds up fast across multiple fixtures.

Business License Requirements

The City of Columbia requires a local business license before you can pull permits. The application process includes LLR registration verification, meaning the city confirms your state license is active and in good standing before issuing your local license.

If you're working in unincorporated Richland County versus the City of Columbia proper, verify which jurisdiction the project address falls under. The permit processes overlap but aren't identical, and pulling a city permit for a county address (or vice versa) creates complications.

Getting Started

If you're expanding into the Columbia market from another part of the state, plan for a setup period. Register in the eTrakit portal, apply for your local business license, and confirm your LLR verification clears before scheduling any project starts.
