Jasper County - Planning and Building Department (Building Inspections)

Yes, a permit is required to replace a roof in Unincorporated Jasper County, SC, issued by Jasper County - Planning and Building Department (Building Inspections). The Department lists roof replacement and repairs as permit work: "A building permit is required for new construction, additions, alterations, repairs, roof replacement, ..." Apply online through the County's permitting portal (Planning & Building, "Apply online"). Residential applicants provide the contractor's "name, address, phone number, and both SC & Jasper County License numbers", and "All Contractors and/or Subcontractors must submit a copy of their Jasper County Business License." State law requires the permit office to see evidence of the contractor's Residential Builders Commission registration or licence, or of an exemption, before it issues the permit; an owner doing the work under the state exemption must record the County's Homeowner Builder Disclosure Statement at the Register of Deeds before the permit is issued. No building permit is issued without a County Treasurer's certificate "verifying that all county taxes presently due have been paid in full by the applicant and on the real property" (Section 6-103). The permit card must be posted "in a location on the premises visible in plain sight from the adjacent right-of-way or access drive" before work starts (Section 6-64). Starting permit work before the permit is issued doubles the administrative and permit fees (Section 6-65). Confirm with the Department (843-717-3650) that the property is in its jurisdiction.

Registration details
  • state_level: Roofing is a named Residential Specialty Contractor classification of the South Carolina Residential Builders Commission: "Roofers: the installation, alteration and repair of materials common to the residential building industry that form a watertight, weather resistant surface for roofs and decks, including all accessories, flashing, valleys, gravel stops and roof insulation panels above the roof deck." A residential specialty contractor is one who contracts to do "construction work, repairs, improvement, or reimprovement which requires special skills and involves the use of specialized construction trades or craft, when the undertakings exceed five hundred dollars" (S.C. Code Section 40-59-20), and "all residential specialty contractors must be registered, by the commission" (Section 40-59-220(A)). A residential builder, one who undertakes the "construction, repair, improvement, or reimprovement of a residential building" where "the cost of the undertaking exceeds five thousand dollars", must be licensed. The permit office "shall refuse to issue a permit for an undertaking which requires licensure or registration under this chapter unless the applicant has furnished evidence that he is either licensed or registered in accordance with this chapter or exempt from the requirements of this chapter" (Section 40-59-280). Section 40-59-260 states that the chapter "does not apply to an owner of residential property who improves the property" where the owner "does the work himself, with his own employees, or with licensed contractors or registered entities or individuals" and the structure is for the owner's or family's own occupancy and not for sale or rent, and Section 40-59-270 states that the chapter "does not apply to a person licensed under Chapter 11" for that work.
  • county_level: Jasper County Code Section 6-71 provides that "All persons requesting to apply or purchase permits within the unincorporated areas of Jasper County, must comply with South Carolinas' Labor and Licensing Regulations regarding proper licensing as outlined in the Residential Builders Commission Licensed Law and/or the General and Mechanical Contracting Act." The Department asks residential applicants for "the Contractor's Information (name, address, phone number, and both SC & Jasper County License numbers)" and states that "All Contractors and/or Subcontractors must submit a copy of their Jasper County Business License." The Jasper County business licence is a general business licence, not a roofing credential; the County's building chapter (Chapter 6, Article II, read in full) sets no County licence or registration for roofers. An owner who does the work under the state exemption signs the County's Homeowner Builder Disclosure Statement, which "MUST BE COMPLETED & SIGNED BY ALL PROPERTY OWNERS AND RECORDED AT THE REGISTER OF DEEDS OFFICE PRIOR TO A PERMIT BEING ISSUED" (Section 6-72).

Adopted code
Jasper County Code Section 6-51, Technical codes adopted by reference (as amended by Ord. No. 2023-07, May 15, 2023), adopts the codes "as adopted and amended by the state's department of labor, licensing, and regulation, which must be mandatorily adopted by the county", "including Chapter One", "as the regulations governing the construction of buildings and other structures in the county with effective dates established by the South Carolina Building Code Council", among them the "International Residential Code, 2021 Edition published by the International Code Council, Inc. with South Carolina Building Code modifications and Appendices" and the "International Existing Building Code, 2021 Edition". Its only local change to the residential code is to Section 105.2(7), which "is to include 'Prefab pools that are 4 foot or greater in height.'" Under Section 6-51(c) the adopted codes "shall be controlling in the use, maintenance, and occupancy of all structures located within the unincorporated areas of the county." At the state level, S.C. Code Section 6-9-10(A) requires every county to enforce the building codes the Building Codes Council adopts and provides that "The municipality or county shall enforce only the national building and safety codes provided in this chapter." The 2021 International Residential Code with South Carolina modifications (S.C. Code of Regulations 8-1200 et seq.) is the mandatory state residential code for permits applied for before January 1, 2027, the date the Building Codes Council set for local jurisdictions to implement the 2024 edition with South Carolina modifications (State Register Vol. 50, Issue 5, May 22, 2026). The Council's building code adoption page lists no approved local roofing modification for Jasper County. The one South Carolina change to the roofing chapter replaces the drip-edge section: "A drip edge shall be provided at eaves and rake edges of asphalt shingle roofs where required by the manufacturer." (Reg. 8-1228, IRC Section R905.2.8.5.) The County's technical-codes article (Chapter 6, Article II, read in full) contains no roofing provision of its own.
Impact-resistant roofing
Not required — Neither Jasper County's technical-codes article (Chapter 6, Article II, including Section 6-51 adopting the state codes) nor the South Carolina modifications to the 2021 International Residential Code amends the roofing chapter's impact provisions, and the Building Codes Council lists no approved roofing modification for the County; no UL 2218 or Class 4 impact requirement appears in the County's adopted code or its amendments.
Repair permit threshold
Jasper County sets no dollar, area or percentage threshold below which roof work needs no permit. The Department's own answer to "When is a building permit required?" is: "A building permit is required for new construction, additions, alterations, repairs, roof replacement, electrical, plumbing, installation of heating and air systems, accessory structures, swimming pools, to move or demolish an existing structure, and to install a manufactured house. The only work exempt from a permit is residential accessory structures that are less than 200 square feet, commercial accessory structures that are less than 120 square feet, fences less than 7 feet in height, and retaining walls less than 4 feet in height." The County Code provides that "No work relating to the codes adopted by this article shall commence until a valid permit for such work has been issued by the permitting department" (Section 6-64), and adopts the 2021 International Residential Code "including Chapter One" (Section 6-51), whose permit and exemption sections are not restated here. The residential building permit fee (Section 6-85) is $69.00 for a total valuation of "$0 - $2,000.00", plus a nonrefundable $25.00 administrative fee per permit (Section 6-69), with no separate roofing line. Under Section 6-65, "For work commencing prior to obtaining proper permit(s), all administrative and permit fees specified herein shall be doubled."
Wind design criteria
130 mph along the one wind line the Building Codes Council's map draws through the County; ask the Building Department for the design wind speed at the address. The South Carolina modification to IRC Section R301.2.1 requires buildings to be "constructed in accordance with the previously published maps by the South Carolina Building Codes Council", adds that "The local building official may delineate the wind design category within their jurisdiction provided that it does not surpass those provided on the Applied Technology Council (ATC) website", and states that "Asphalt shingles shall be designed for wind speeds in accordance with Section R905.2.4." The Council's wind and seismic map for Jasper County (drawn on the SCDOT General Highway System map of Jasper County) shows a single wind line labelled "130 MPH" crossing the northwest of the County; most of the County, including the areas around Ridgeland and Hardeeville, lies on the seaward side of that line, and the map draws no other wind line inside the County. The map's note reads: "Wind speed, shown in miles per hour, applies at all points along the length of its corresponding (blue) line. Interpolation between wind speed lines is determined by the AHJ as permitted by Figure R301.2(4)(A) of the 2015 International Residential Code." The Council's map page says the county maps were approved "for the 2021 code cycle based on the 2015 International Residential Code" and are "intended to be the primary source for defining the appropriate boundaries for wind and seismic design in South Carolina for single- and two-family dwellings". The County publishes no climatic and geographic design criteria table of its own.
Roof layer limit / recover
Two layers maximum. The 2021 International Residential Code, Section R908.3.1.1 Roof recover not allowed, bars a roof recover "Where the existing roof has two or more applications of any type of roof covering", as well as where the existing roof or covering is water soaked or deteriorated to the point it is not an adequate base, or is slate, clay, cement or asbestos-cement tile. The South Carolina modifications to the 2021 IRC do not change the reroofing section, and Jasper County's technical-codes article (Chapter 6, Article II, read in full), which adopts the 2021 IRC with South Carolina modifications, adds no reroofing rule of its own and neither deletes nor excepts that section, so the base rule applies unmodified.
Deck & sheathing requirements
Jasper County applies the 2021 International Residential Code with South Carolina modifications. Neither the County's technical-codes article (Chapter 6, Article II, read in full) nor the South Carolina modifications amend the roof sheathing provisions (Section R803), so the base IRC provisions on roof sheathing apply unmodified.
Sales & use tax
9% in unincorporated Jasper County: the 6% state sales tax (S.C. Code Sections 12-36-910 and 12-36-1110) plus three local taxes collected by the Department of Revenue, 3% together, listed on the "Unincorporated Jasper" row of SCDOR form ST-575, South Carolina Sales Tax Rate by Municipality (Rev. 2/5/26), as "ECI (5271), TT (1027), LO (1027)" with a total tax rate of 9% (Education Capital Improvement, Transportation Tax and Local Option). SCDOR's county map "South Carolina Local Tax Designation by County Effective May 1, 2026" (ST-500, Rev. 3/9/2026) also shows Jasper at 9% with "LO, TT, ECI". The Department of Revenue notes that ST-575 does not include "Local taxes directly collected by the counties or municipalities". South Carolina taxes the roofer, not the homeowner's contract: Reg. 117-314.2 provides that "Building materials when purchased by builders, contractors, or landowners for use in adding to, repairing or altering real property are subject to either the sales or use tax at the time of purchase by such builder, contractor, or landowner", and its list of building materials names "roofing materials". Repair and replacement work are treated alike.
