Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.
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.
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.
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. 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.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
