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.

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.
Initial plan review: approximately 2 days for residential projects and 14 days for commercial projects after submission; requested inspections are conducted within 48 hours.
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.
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. 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.
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.
