Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
Marlboro County project specifications identify the 2021 International Building Code and South Carolina Building Code. For 2026, the applicable South Carolina cycle is the 2021 IBC, IRC, IMC, IPC, IFC and IFGC with South Carolina amendments, plus the 2020 National Electrical Code and other applicable state-modified standards.
Inspection lane
Residential applications are submitted through the AccessGov portal and the portal directs applicants to the inspection card for required inspections. Confirm inspection scheduling with Building Codes Enforcement at 843-479-5602. Safe Built is used for third-party plan review and inspections on some county projects.
Minor-work playbook
N/A; the public AccessGov form documents an owner-builder affidavit exception when the owner is actively in charge, has construction knowledge or expertise, and receives no wage, fee or commission, but it does not publish a complete minor/cosmetic exemption list. Confirm exemptions with Building Codes Enforcement.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Residential applications are submitted through the AccessGov portal and the portal directs applicants to the inspection card for required inspections. Confirm inspection scheduling with Building Codes Enforcement at 843-479-5602. Safe Built is used for third-party plan review and inspections on some county projects.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 843-479-5602.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
