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.

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 803-785-8130.
Commercial plan review may take up to three weeks; no standard residential timeline was published in the reviewed county materials.
Schedule inspections through the BluePrince portal, or contact Building Inspections at 803-785-8130 or BuildingInspections@lexingtoncounty.sc.gov with the permit number, inspection type, desired date and contact information. The county's residential guidance lists footing, utilities-under-slab, slab, rough-in, additional inspections as needed and final inspection; the permit holder should generally give one business day's notice. Commercial guidance states a 4:00 p.m. weekday cutoff for next-day inspections.
Lexington County applies the current South Carolina mandatory code editions in the unincorporated county and specified participating municipalities. For 2026 this means the 2021 International Building, Residential, Mechanical, Plumbing, Fire and Fuel Gas codes with South Carolina amendments, and the 2020 National Electrical Code with South Carolina amendments; applicable accessibility, energy, existing-building and other referenced standards also apply under the state code cycle. Ordinary repairs and maintenance; fences; retaining walls unless supporting a surcharge; water tanks; sidewalks, driveways and patios; painting, papering, tiling, carpeting, cabinets and similar cosmetic finish work; swings and playground equipment accessory to a one- or two-family dwelling; one-story detached storage structures accessory to a one- or two-family dwelling up to 200 square feet; agricultural or nursery shade-cloth structures without service systems; exterior-wall-supported window awnings; and movable cases, counters or partitions no higher than 5 feet 9 inches. Zoning, floodplain and land-disturbance approvals may still be required.
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.
