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
For 2026, Florence County enforces South Carolina's mandatory 2021 code cycle: the 2021 International Building, Residential, Fire, Plumbing, Mechanical, Fuel Gas, Existing Building, and Swimming Pool and Spa Codes with South Carolina modifications; 2020 National Electrical Code with South Carolina modifications; and 2009 International Energy Conservation Code.
Inspection lane
The permit holder or authorized agent must call 843-676-8600 at the required construction stages to request foundation, framing, rough-in, final, and trade inspections. Requested inspections are conducted within 48 hours. The county lists underground, rough-in, and final inspection requirements for electrical, plumbing, mechanical, and gas work.
Minor-work playbook
The county application identifies agricultural-only work and the South Carolina owner-builder exemption for qualifying residential construction, with required filing of the owner-builder notice. Ordinary finish work and other minor exemptions are governed by the applicable South Carolina code; the county advises applicants to confirm whether the proposed construction, alteration, repair, move, conversion, or demolition requires a permit.
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
The permit holder or authorized agent must call 843-676-8600 at the required construction stages to request foundation, framing, rough-in, final, and trade inspections. Requested inspections are conducted within 48 hours. The county lists underground, rough-in, and final inspection requirements for electrical, plumbing, mechanical, and gas work.
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.

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 843-676-8600.

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.
