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 work, Charleston County lists the 2021 South Carolina Building, Existing Building, Fire, Fuel Gas, Mechanical, Plumbing, Residential, and Swimming Pool and Spa Codes; 2020 National Electrical Code; 2009 International Energy Conservation Code; and the applicable ICC accessibility standard. The county consolidated several sub-trade permits into a Main Building Permit effective July 1, 2026.
Inspection lane
Request inspections through the Charleston County CSS portal or by emailing InspectionRequest@CharlestonCounty.org; phone calls and voicemails are not accepted for inspection requests. Include permit number, contractor name and phone, project address, and requested inspection date. Requests received before 4:00 p.m. are scheduled one business day out; later requests are scheduled two business days out. Inspections occur Monday-Friday except designated holidays.
Minor-work playbook
The county fee schedule states that construction valued at $1,000 or less has no permit fee unless an inspection is required, in which case a permit and $75 fee are required. No complete minor/cosmetic exemption list was published; ordinary repairs, remodels, additions, electrical/plumbing upgrades, and change-of-use work should be confirmed with Building Inspection Services. A homeowner may obtain a permit for their own work when they or immediate family perform it and they will live in the home at least two years.
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
Request inspections through the Charleston County CSS portal or by emailing InspectionRequest@CharlestonCounty.org; phone calls and voicemails are not accepted for inspection requests. Include permit number, contractor name and phone, project address, and requested inspection date. Requests received before 4:00 p.m. are scheduled one business day out; later requests are scheduled two business days out. Inspections occur Monday-Friday except designated holidays.
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 843-202-6930; Code Enforcement 843-202-6994.
The permit process guide states that after completeness review, plan review, and payment, a permit will be issued the next business day. Inspection requests are generally one business day out when received before 4:00 p.m.

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.
