Bathroom Remodeling in Columbia, SC: Plan and Hire

Masters' Guild · Updated

For Bathroom Remodeling in Columbia, SC, choose a contractor who will define the scope, identify the plumbing tradesperson, handle applicable permits and schedule inspections before covering the work. Start by deciding whether you want cosmetic updates or changes to plumbing, wiring or layout. The City exempts painting, flooring and other cosmetic work from building permits, but requires permits for regulated work. Ask each bidder to price the same scope and explain how you will manage bathroom access during construction. [1] [2]

Define the bathroom you need before requesting quotes

Write down what you want to keep, replace and move. Separate paint, flooring and hardware from the shower enclosure, vanity, toilet, lighting and ventilation. Tell bidders whether you want to retain the fixture locations. Include photographs, room measurements and any leaks or damaged surfaces you have noticed.

Describe how you use the room. Ask for enough storage, reachable controls and space to enter the shower or help a family member. For a proposed layout change, have the contractor explain access to supply lines, drains and wiring before you select fixtures. Request a written scope for waterproofing, shower drainage, ventilation and repairs to surfaces exposed during demolition.

Assign responsibility for permits and trade work

For property inside Columbia city limits, the City requires a permit for regulated work. A building trade permit covers work such as electrical, mechanical, plumbing and gas that typically does not need review by other City agencies. A building permit involves Permitting and Zoning review and typically another division. Confirm which process applies to your proposed bathroom scope with the Development Center. [1]

Ask the lead contractor to name the person who will perform the plumbing and provide their license details for verification through South Carolina LLR. The state requires a license when residential plumbing work exceeds $500. Ask who will supervise other trades, submit applications and resolve inspection corrections. Request proof of insurance and put these responsibilities in the agreement. [3]

Check the property's permitting jurisdiction before relying on the City's instructions. If another municipality or county handles your address, ask that office about your scope. Give the responsible office a specific description, including fixture relocation, wiring changes and any wall alterations, rather than asking whether a bathroom remodel needs a permit.

Compare written scope and allowances

Request separate amounts for demolition, disposal, trade work, waterproofing, tile, fixtures, permits and finish work. Ask bidders to identify owner-supplied items and exclusions. For each allowance, record the amount and what it covers, including installation and accessories. Compare the same fixture selections across bids before deciding which proposal fits your budget.

Ask how the contractor will handle concealed damage. Agree on a process that includes photographs, a proposed repair, a written price and your approval before additional work. Specify payment milestones, cleanup, warranty terms and the documents you expect at completion. Use site-specific written quotes to set the project budget.

Plan bathroom access around inspections

Have the contractor identify the inspection stages in the proposed schedule. Columbia requires rough-in inspections for applicable plumbing, electrical, ducts, vents and framing work, and prohibits concealing those items before approval. The City also requires final inspections for plumbing, electrical and other listed systems. Each subcontractor must request their own inspections. [2]

Columbia's inspection request cutoff for the following day is 3:00 pm. Requests after that time go to the day after next, and the City offers no same-day inspections. Ask who will track requests and confirm approval before the crew closes walls. Agree on an alternative bathroom arrangement, water shutoff notice, dust control and access hours before demolition. [2]

Select fixtures with operating costs in mind

EPA describes standard showerheads as using 2.5 gallons per minute. WaterSense showerheads use no more than 2.0 gallons per minute and must meet independently certified performance criteria, including spray force and coverage. Ask for the exact model number and compare the spray pattern and controls before ordering. [5]

Columbia Water publishes separate in-city and out-of-city rates. Its schedule effective July 1, 2026 charges residential customers for additional water beyond the first three units and charges sewer use per unit of water used. Check your service location and current bill when considering fixture operating costs. The chart shows published usage rates, not a household savings estimate or remodeling price. [4]

Local details that affect your job

Submit the right application before setting demolition dates

Columbia directs applicants for a residential building trade permit to submit the completed application and required plans to the Development Center. For a building permit, it directs applicants to consult the Before You Start handout and project checklist, then submit an application, plans and a $25 plan review fee. Call 803-545-3420 to confirm submittal requirements for your bathroom scope before committing to a start date. [1]

Check historic or design district status

The City states that a property in a designated Historic or Design District requires a Certificate of Design Approval before it can issue a permit, typically during permit review. If your project needs a permit, ask Planning Staff at 803-545-3222 how this requirement applies to the proposed work. Confirm the process before treating permit approval as a routine scheduling step. [1]

Leave room for the City's inspection schedule

The City offers no same-day inspections and uses a 3:00 pm cutoff for next-day requests. Ask the contractor to account for this when promising when you can use the bathroom again. For inspection assistance, the Building Inspections office lists 803-545-3422. [2]
