The City of Columbia Development Center is the single point of entry for construction review and permitting, coordinating concurrent reviews and issuing through the Access portal.
This Columbia building permit guide covers what requires a permit, the difference between a Building Permit and a Building Trade Permit, the Certificate of Design Approval that historic and design districts require, and the 3pm inspection cut-off.
Scope: inside the City of Columbia limits. Outside them, Richland County or Lexington County permits.
Check for a design overlay before you file. If the property sits in a designated Historic or Design District, a Certificate of Design Approval is required before a permit can be issued. Finding out at plan review costs a full board cycle.
What requires a permit in Columbia?
All regulated work performed in the City of Columbia must have a permit. The Development Center is the single point of entry for construction review and permitting, coordinating reviews concurrently where possible, and the Building Inspections Division reviews plans and monitors construction against the adopted codes.
Columbia issues two different things, and knowing which you need saves a review cycle. A Building Trade Permit covers electrical, mechanical, plumbing and gas work that typically does not require review by Zoning, the Plans Examiner, Engineering or any agency outside Permitting. A Building Permit requires review by Permitting and Zoning and typically at least one other city division. Filing the heavier record for light trade work invites reviewers who did not need to be involved.
As the state capital, Columbia carries an unusually dense overlay of design control. If the property is within a designated Historic or Design District, a Certificate of Design Approval is required before a permit can be issued, typically obtained during the permit review process. The Land Development and Zoning divisions administer the city's Unified Development Ordinance over everything else.
The enforced code is the South Carolina Building Codes — the International Codes as adopted with South Carolina modifications by the South Carolina Building Codes Council under S.C. Code Ann. § 6-9-50, then administered and enforced locally. South Carolina is mid-changeover. The codes in force today are the 2021 South Carolina Building Codes, effective 1 January 2023. On 26 August 2025 the Building Codes Council adopted the next cycle — the 2024 editions of the International Building, Residential, Fire, Plumbing, Mechanical and Fuel Gas Codes, together with the 2023 National Electrical Code — and set the implementation date for every municipality and county as 1 January 2027. Design to the 2021 codes for a permit pulled now; design to the 2024 codes for anything that will be applied for after the turn.

Columbia building department: who handles permitting
The Development Center takes in plans and shepherds projects from submittal to permit, coordinating reviews concurrently where it can. Permits may be applied for online through the Access portal at access.columbiasc.gov, or by email to the Development Center. Payment is made online through the portal or in person at 1401 Main Street, third floor.
The city divides its published guidance cleanly into residential — one and two family — and commercial or multi-family, each with its own codes page, inspections page, inspection contacts and permit application checklists. Start from the correct branch, because the checklists differ and a residential checklist will not carry a commercial submittal.
Some projects need land development review beyond the permit: Planning Commission, Board of Zoning Appeals, or a design review commission. Columbia publishes a handout called Before You Start alongside development checklists precisely so applicants can identify these before filing rather than discovering them mid-review.

⏰|Inspections are booked through the Access portal, and the cut-off for next-day is 3:00pm. Columbia does not offer same-day inspections at all. That is a materially different rhythm from Spartanburg County's 6:30am same-day window, so crews working both sides of the Midlands need two habits, not one.
Columbia permits: record types and what each covers
Columbia's permit set turns on which review path the work needs, so the record type is the first decision rather than the last:
Residential permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures above the local size threshold | Full plan review against the adopted South Carolina Residential Code, plus zoning | Valuation-based |
| Renovation / alteration | Structural changes, layout changes, or added plumbing, mechanical, or electrical | Plan review scaled to scope; the property maintenance and existing-building provisions apply only where locally adopted by ordinance | Valuation-based |
| Reroof | Roof covering replacement, recover, and structural deck repair | Dry-in and deck inspection; plan review rarely required | Valuation or squares |
| Solar photovoltaic | Rooftop or ground-mount arrays, with or without battery storage | Electrical review led, with structural review of the attachment | Flat or system-size based |
| Battery energy storage | Wall or floor-mounted storage added to a dwelling | Electrical review plus fire separation and location check | Flat or per-permit minimum |
| Electrical | Service changes, panel upgrades, new circuits, EV chargers, and rewiring | Trade review; filed under a mechanical contractor holding the Electrical subclassification | Per-permit minimum or per-device |
| Plumbing | New piping, repipes, fixtures, gas piping, and water heater replacement | Trade review under a mechanical contractor holding Plumbing | Per-permit minimum or per-fixture |
| Mechanical / HVAC | Changeouts, new ductwork, and refrigeration | Trade review under Air Conditioning, Heating, or Refrigeration subclassifications | Per-permit minimum or per-unit |
| Deck and porch | New decks, screened porches, and structural rebuilds | Structural review of footings, ledger attachment, and guards | Valuation or flat |
| Swimming pool | In-ground and above-ground pools, including residential pools | Barrier, bonding, and electrical review; residential pool work now requires a Swimming Pools subclassification or a Residential Builder licence | Valuation or flat |
| Manufactured home set-up | Placing or re-siting a manufactured home | Zoning, floodplain, and anchoring review; filed by an LLR-licensed contractor | Flat or per-unit |
| Demolition | Full or partial demolition of a dwelling or accessory structure | Utility disconnect confirmation and site restoration check | Flat |
Commercial permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New commercial construction | Ground-up commercial, industrial, and institutional buildings | Concurrent review against the adopted South Carolina Building Code, fire, and zoning | Valuation-based |
| Tenant improvement / upfit | Interior fit-out of an existing tenant space | Building, trade, and life-safety review; accessibility attaches on change of use | Valuation-based |
| Change of occupancy | Converting a building or space to a different use group | Occupancy classification, egress, and accessibility review | Valuation or flat |
| Commercial electrical | Service, distribution, and branch circuit work | Trade review under a mechanical contractor holding Electrical | Per-permit or valuation |
| Commercial plumbing | Process piping, fixtures, backflow, and grease waste | Trade review; backflow and grease interceptor sign-off where applicable | Per-fixture or valuation |
| Commercial mechanical | Rooftop units, kitchen exhaust and hood systems, and refrigeration | Trade review; kitchen exhaust and hood systems sit under Packaged Equipment | Per-unit or valuation |
| Commercial reroof | Roof covering replacement on a commercial structure | Deck, dry-in, and attachment inspection | Valuation or squares |
| Signage | Wall, ground, and illuminated signs | Zoning review for size and placement, plus electrical where illuminated | Flat or per-sign |
| Land disturbance | Clearing, grading, and stormwater-triggering site work | Erosion and sediment control review, separate from the building permit | Acreage-based |
| Commercial demolition | Full or partial demolition of a commercial structure | Utility disconnect, asbestos notification, and site restoration | Flat or valuation |
Residential
- Single-discipline review in most cases
- Trade records filed separately under Title 40 Chapter 11 licences regardless of job value
- Residential builder licence required above the statutory threshold; residential specialty above a much lower one
- Septic properties need SCDES approval before the county can issue
Commercial — multi-discipline
- Concurrent review across building, trades, fire, and zoning
- Signed and sealed plans across every affected discipline
- Licence group caps the value of a single bid or job, separately from the permit
- Accessibility and life-safety review attach to any change of occupancy
Records you will actually see in Columbia
| Record | What it covers |
|---|---|
| Building permit | Requires Permitting and Zoning plus at least one other division |
| Building trade permit | Electrical, mechanical, plumbing and gas without outside review |
| Zoning permit | Some are issued without a building permit at all |
| Certificate of Design Approval | Required first in Historic and Design Districts |
| Change of occupancy | Inspected when a business moves or opens in a new location |
| Site plan review | Subdivision and land development |
| Demolition permit | Full or partial demolition |
Solar permits in Columbia
Solar is reviewed on two tracks at once across South Carolina: the electrical side (conductors, overcurrent protection, rapid shutdown, labelling, and the service or supply-side connection, against the adopted National Electrical Code) and the structural side (attachment detail, rail spacing, and whether the existing framing carries the added dead load).
In Columbia solar usually files as a Building Trade Permit where no outside review is needed, but a roof-mounted array on a property inside a Historic or Design District will need a Certificate of Design Approval first, which moves it onto the heavier path. Confirm which classifications your installer actually holds before the application is filed, because a single rooftop array can cross the general contractor Miscellaneous Metals subclassification for the panels, Roofing or Building for the mounting, and a mechanical contractor holding Electrical for the wiring and connections.
The licensing split is the part that catches installers. South Carolina puts solar panel installation under the general contractor Miscellaneous Metals subclassification, but roof mounting may only be performed by a general contractor holding Roofing or Building, and wiring and connections may only be performed by a mechanical contractor holding Electrical. Structural upgrading of the roof to carry the array goes to a general contractor with Building or Structural Framing. One array, potentially three licences.
Utility interconnection runs on its own clock alongside the permit. Dominion Energy South Carolina, Duke Energy Carolinas and Duke Energy Progress, Santee Cooper and the state's electric cooperatives each set their own application, meter, and witness-test sequence. Permission to operate is not something the building department controls, so plan for the two tracks to finish at different times.
Roofing permits in Columbia
A roof covering replacement needs a permit across most of South Carolina. The permit is usually quick, but it is not optional, and the inspection that matters happens before the covering goes on rather than after.
Because South Carolina enforces a statewide adopted code, there is no state product-approval database to search and no approval number to cite on the application. The assembly has to comply with the adopted code and the manufacturer's listed installation instructions, and that pairing is what the inspector checks — which makes the manufacturer's instructions a document worth having on site.
A reroof in Columbia inside a Historic or Design District needs a Certificate of Design Approval before the permit can issue, because roof covering is visible exterior work and falls squarely within design review. Roofing is its own general contractor subclassification in South Carolina, and it absorbed the former General Roofing and Specialty Roofing classifications, so an older pocket card can read differently from the current licence record — check the LLR verification lookup rather than the card alone.
Sequencing is where reroofs go wrong. The deck and dry-in condition has to be visible when the inspector arrives, so covering it first means opening it back up. Where a previous layer has been torn off, expect attention to deck fastening and to any sheathing replaced along the eaves.
Columbia permit cost
Columbia charges a plan review fee alongside the permit fee, and on residential work the plan review fee is submitted with the completed application and plans rather than after review. Permit and plan review fees can be paid online through the Access portal or in person at 1401 Main Street.
Permit issuance follows approval and payment, in that order. Fees scale with the type and valuation of work, and trade permits are charged as their own records. Confirm current amounts against the city's payments and fee schedule pages before budgeting.
| Fee component | How it works |
|---|---|
| Building permit | Per city fee schedule, by type and valuation |
| Plan review | Submitted with the residential application and plans |
| Building trade permits | Electrical, mechanical, plumbing, gas charged separately |
| Payment | Online via the Access portal, or in person at 1401 Main Street |
| Sequence | Approval, then payment, then issuance |
| Design districts | Certificate of Design Approval required before issuance |

Columbia trade permits
Electrical, mechanical, plumbing and gas work are filed as Building Trade Permits by licensed contractors. Four Columbia specifics:
Pick the right record
A Building Trade Permit covers work that does not need Zoning, the Plans Examiner or Engineering. A Building Permit pulls in Zoning and at least one other division. Filing the wrong one adds reviewers and time.
Licensed contractors get the portal
The Access portal is available to licensed contractors to apply and pay for permits. Where the portal does not carry the permit you need, the Development Center accepts applications by email.
3pm for next day, never same day
Inspections are scheduled through the Access portal with a 3:00pm cut-off for next-day booking. Columbia does not do same-day inspections.
Small accessory structures may need only zoning
A detached, uninhabited accessory structure of 200 square feet or less falls under a zoning permit without a building permit. Check the zoning route before assuming a full application.
Columbia permit application: how to apply step by step
Here is how to get a building permit in Columbia, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Columbia sits mainly in Richland County and extends into Lexington County. Outside the city limits the county permits, so settle jurisdiction from the parcel.
Work from the city's Before You Start handout and the appropriate development checklist, using the residential branch for one and two family work and the commercial branch for everything else.
If the property is in one, a Certificate of Design Approval is required before the permit can issue. Identify this before filing so it can run inside the review rather than after it.
A Building Trade Permit for electrical, mechanical, plumbing or gas work needing no outside review; a Building Permit where Zoning and other divisions must review.
File through the Access portal, or by email to the Development Center. Submit the plan review fee with the residential application. Permit issuance follows approval and payment.
Book through the Access portal, remembering the 3:00pm next-day cut-off and that there are no same-day inspections. Keep the permit and approved plans on site through to Certificate of Occupancy.
Inspections in Columbia
The Building Inspections Division reviews plans and monitors construction work to ensure it conforms to the adopted building codes. Inspections are requested through the Access portal, with a 3:00pm cut-off for next-day scheduling and no same-day inspections. The city publishes separate residential and commercial inspection contacts.
Inspections are not only for construction. Columbia's staff also inspect spaces for businesses moving into or opening in a new location, to confirm the space is safe and meets building codes. On a tenant relocation that inspection is the gate on opening, so it belongs on the programme from the start rather than being treated as a formality at the end.
Where a project needs land development review, the Planning Commission, Board of Zoning Appeals and the design review commissions each work to a published calendar with their own agendas and application deadlines. Missing a filing deadline costs a full cycle regardless of how ready the drawings are.
Keep the permit and approved plans on site throughout. For inspection help, Building Inspections is on 803-545-3422.

Frequently asked questions
Who issues building permits in Columbia, SC?
The City of Columbia Development Center, which is the single point of entry for construction review and permitting, working with the Building Inspections Division. Outside the city limits, Richland County or Lexington County permits.
What is the difference between a Building Permit and a Building Trade Permit?
A Building Trade Permit covers electrical, mechanical, plumbing and gas work that typically does not require review by Zoning, the Plans Examiner, Engineering or any agency outside Permitting. A Building Permit requires Permitting and Zoning and typically at least one other city division.
How do I apply for a Columbia building permit?
Through the Access portal at access.columbiasc.gov, which licensed contractors can use to apply and pay. Permits may also be applied for by email to the Development Center where the portal does not carry the permit type.
What time is the inspection cut-off in Columbia?
3:00pm for next-day scheduling, through the Access portal. Columbia does not offer same-day inspections.
Do I need design approval before my permit?
If the property is located within a designated Historic or Design District, yes — a Certificate of Design Approval is required before a permit can be issued. It is typically obtained during the permit review process.
Where do I pay for a Columbia permit?
Online through the Access portal, or in person at 1401 Main Street, third floor. Permit issuance follows approval and payment.
Do I need a building permit for a small shed?
A detached, uninhabited accessory structure of 200 square feet or less falls under a zoning permit rather than a building permit in Columbia. Confirm the zoning route before assuming a full building application.
Does Columbia inspect for a business moving into a space?
Yes. City staff provide inspections for businesses when they move or open in a new location, to make sure the space is safe and meets building codes. Treat that inspection as a gate on opening.
Which checklist should I use?
The city splits its guidance into residential — one and two family — and commercial or multi-family, each with its own codes, inspections and application checklists. Start from the correct branch, as the checklists differ.
What is the Unified Development Ordinance?
The city ordinance administered by the Land Development and Zoning divisions, covering subdivision of land, group developments, where uses can be established, and the size and placement of buildings.
Who do I call about a Columbia permit?
The Development Center on 803-545-3420 for submittal requirements and the permit process, or Building Inspections on 803-545-3422 for inspection questions.
