Do you need a building permit in McCormick County, South Carolina?

Yes. Construction in unincorporated McCormick County is under local building-permit and building-code enforcement.1 South Carolina requires counties and municipalities to enforce the mandatory building codes, while local administrative procedures remain the county's responsibility.910

The official county guidance adds an important distinction: some work that does not require a building permit may still require a zoning permit, so contact Planning & Zoning before starting any project.311 The available county material does not give a complete project-by-project exemption list or fee schedule. Ask the department to confirm the permits, plan documents, inspections and current fees for the proposed work before ordering materials. Building permit fees vary by local jurisdiction rather than following one statewide price.12

Who issues McCormick County building and zoning permits?

McCormick County Planning & Zoning is the first stop for building and zoning questions in the unincorporated county. The department reviews zoning use permits and directs applicants to contact it before beginning a project.133 The office is at 610 South Mine Street, McCormick, and its published phone is (864) 852-2231.11

Tell the office the parcel number, proposed use, structure type and whether the site has public sewer before asking which applications are required. The county's accessible guidance confirms only a partial workflow, so the office should also confirm required drawings, inspections, fees and whether a certificate of occupancy will be needed. South Carolina requires inspections under the code in effect for the locality when the original building permit was issued.14

Does McCormick County have zoning?

Yes. McCormick County administers zoning for new development and continuing land occupancy in areas governed by the county ordinance, while incorporated municipalities may have separate local rules.2 The county Zoning Officer reviews and approves or denies zoning use permits.13 Subdivision and land-development activity is also regulated under county subdivision rules, although the available material does not establish every review threshold or procedure.15

Do not assume a rural or wooded parcel is unrestricted. Confirm the parcel's jurisdiction and zoning designation with Planning & Zoning before relying on a listing description.11 The available county material does not confirm district-specific minimum lot size, dwelling size, setbacks, lot coverage, building height or accessory-dwelling standards. Ask the office for the standards tied to the parcel's exact district and proposed use.

How do septic permits work in McCormick County?

SCDES, not the county, handles onsite wastewater approval for a home or manufactured home where public or community sewer is unavailable.5 Confirm sewer availability first because an onsite wastewater permit cannot be issued where public sewer is accessible.16 Then apply through the SCDES ePermitting portal; the published septic application fee is $150, and an approved Permit to Construct is valid for five years.417

SCDES evaluates the site before approval, and the county cannot issue the building permit without the septic permit.18 The installer must schedule inspection before covering a new system.19 About 45.7% of county soils are rated without severe limitations for a conventional drain field, so soil and site evaluation should come before finalizing the house location.20

Can you live in an RV or tiny home in McCormick County?

Do not assume an RV can serve as a residence on any rural parcel in McCormick County. County material identifies campers as prohibited uses in the Forest Agricultural and Rural Development zoning designations, but it does not supply a complete duration or occupancy rule for every district.6 Ask Planning & Zoning whether the proposed parcel and use qualify before bringing an RV onto the land.11

A county rule specifically addressing tiny-home occupancy could not be confirmed. McCormick County zoning still governs land use, and the statewide building codes govern covered residential construction.29 A tiny house on wheels may raise different zoning, camper and sanitation questions from a foundation-built dwelling. Ask Planning & Zoning to confirm classification, district permission, setbacks and permit requirements, and obtain SCDES approval for septic where public or community sewer is unavailable.4

Building a home in McCormick County: what are the steps?

  1. Confirm that the parcel is in unincorporated McCormick County and ask Planning & Zoning for its zoning designation and applicable use and dimensional standards.211
  2. Verify whether public or community sewer is accessible; if it is not, apply to SCDES for septic approval before seeking the county building permit.164
  3. If using a private residential well, submit the state Notice of Intent and applicable fee before construction.8
  4. Submit the county building and zoning applications and ask the department for the current documents, fees and inspection sequence.13
  5. Schedule the required building inspections and have the septic installer arrange inspection before covering the system.1419
  6. Before occupancy, ask the county which final approvals or certificate are required, because the available material does not confirm McCormick County's complete closeout procedure.

What should you check before buying land in McCormick County?

Start with jurisdiction, zoning and legal access. County zoning regulates land occupancy, and subdivision activity is regulated, so confirm the parcel's district, lawful use and recorded configuration with Planning & Zoning.215 For access from a state highway, SCDOT permits a qualifying residential driveway within the state right-of-way when the location is not hazardous; that directive does not answer access from a county road.21

Check sewer availability and septic suitability before choosing a house site.16 Only about 45.7% of county soils are rated without severe limitations for a conventional drain field.20 The county is about 83.6% wooded, which can affect clearing and site-layout costs.22 Floodplain development procedure was not confirmed, so ask Planning & Zoning which floodplain contact and permits apply to the parcel before closing.11

Watch-outs

  • A project can require a McCormick County zoning permit even when it does not require a building permit.3
  • Campers are prohibited in the Forest Agricultural and Rural Development zoning designations; confirm the parcel's district before planning RV use.6
  • The county cannot issue a building permit for a site without public or community sewer until SCDES issues the septic permit.4
