What Every Homeowner Should Know About Building Permits in Upstate SC
Building a custom home involves far more than selecting a floor plan and choosing finishes. Before any construction begins, your project must be permitted by the local jurisdiction, and every phase of the build will be inspected to verify compliance with applicable building codes. For many homeowners, the permitting and inspection process feels opaque and intimidating, but it does not have to be. Understanding the basics of how permits work in Upstate South Carolina will help you feel confident about what is happening behind the scenes as your builder manages this process on your behalf.
At Grander Construction, we handle all permitting and code compliance for our clients. It is part of the service we provide, and we consider it one of the most important aspects of building a home that is safe, durable, and legally sound. This guide walks you through the essentials so you know what to expect.
Who Issues Building Permits in Upstate SC
Building permits in the Upstate are issued by the county or municipality where your lot is located. The two primary jurisdictions for our service area are Greenville County and Spartanburg County, each of which operates its own building codes department with its own staff, processes, and requirements.
If your lot falls within the city limits of Greenville, Greer, Simpsonville, Mauldin, Spartanburg, or another incorporated municipality, the city may issue permits directly or may defer to the county system depending on local agreements. For example, the City of Greer handles certain permits through its own planning and development office, while other nearby municipalities rely on county-level review. Your builder should verify the correct jurisdiction before submitting any permit applications.
In Greenville County, the Building Codes division falls under the Department of Planning and Development. Their office reviews residential plans for compliance with the International Residential Code (IRC) as adopted and amended by the state of South Carolina. Spartanburg County operates a similar system through its Building Inspections department, also enforcing the IRC with state and local amendments.
What a Residential Building Permit Covers
A residential building permit is not a single document that covers everything. In practice, building a custom home requires multiple permits and approvals. The primary building permit covers the structural work: foundation, framing, roofing, and general construction. Separate permits are typically required for electrical work, plumbing, and mechanical (HVAC) systems. Depending on your lot, you may also need a grading permit, a stormwater management permit, a driveway permit from the county or state DOT, and a septic system permit if public sewer is not available.
If your home will be on a well, a separate well permit is required through the South Carolina Department of Health and Environmental Control (DHEC). Properties connecting to public water and sewer will need tap and connection permits from the relevant utility provider, which might be Greenville Water, Spartanburg Water, Greer Commission of Public Works, or another local provider depending on your location.
The permit application typically includes a complete set of construction drawings, a site plan showing the proposed building footprint relative to property lines and setbacks, an engineered foundation plan if required, and documentation of the energy code compliance strategy. Your builder prepares and submits all of these materials as part of the pre-construction process.
The Inspection Schedule: What Gets Inspected and When
Once your permit is issued and construction begins, the building department will conduct a series of inspections at key milestones throughout the build. Each inspection must be passed before work can proceed to the next phase. This is a standard part of the construction process, and a well-organized builder schedules inspections in advance to minimize delays.
The typical inspection sequence for a custom home in Upstate SC includes the following stages:
Footing inspection: Before concrete is poured for the foundation footings, an inspector verifies that the trenches are the correct depth and width, the soil bearing capacity is adequate, and any required reinforcing steel is in place.
Foundation inspection: After the foundation walls or slab are formed but before the concrete is poured, the inspector checks dimensions, rebar placement, and waterproofing measures.
Framing inspection: Once the structure is framed, sheathed, and roofed but before insulation and drywall are installed, the inspector reviews structural connections, nailing patterns, header sizes, bracing, and window and door installations. This is one of the most thorough inspections in the process.
Electrical rough-in: The electrical inspector reviews all wiring, boxes, panel installations, and circuit layouts before walls are closed up.
Plumbing rough-in: The plumbing inspector checks supply lines, drain and vent piping, and water heater connections before walls and floors are closed.
Mechanical rough-in: The HVAC inspector reviews ductwork installation, equipment placement, refrigerant lines, and ventilation provisions.
Insulation inspection: After insulation is installed but before drywall, the inspector verifies that insulation types, R-values, and installation quality meet energy code requirements.
Final inspection: After all construction is complete, a comprehensive final inspection covers everything from smoke detector placement to handrail heights to GFCI protection in wet areas. Passing the final inspection triggers the issuance of a Certificate of Occupancy, which legally authorizes you to move into your new home.
Key Code Requirements for Upstate SC Homes
South Carolina has adopted the 2018 International Residential Code with state-specific amendments, and local jurisdictions may add their own modifications. Several code requirements are particularly relevant to custom home construction in the Upstate.
Foundation requirements: Due to the clay soils common in the Piedmont region, foundations must be designed to account for expansive soil conditions. This often means deeper footings, specific gravel and drainage provisions, and in some cases, engineered foundation plans prepared by a licensed structural engineer.
Energy code compliance: South Carolina follows the 2009 International Energy Conservation Code (IECC) for residential construction. This establishes minimum requirements for insulation R-values, window U-factors, air sealing, and duct leakage testing. At Grander Construction, we routinely exceed these minimums because our building science approach prioritizes energy performance and long-term comfort.
Wind load requirements: While the Upstate is not in the highest wind speed zones like the coast, homes must still be designed to resist the wind loads specified for our area. This affects roof-to-wall connections, roof sheathing nailing patterns, and the attachment of exterior cladding materials.
Smoke and carbon monoxide detection: Current code requires interconnected smoke alarms in every bedroom, outside each sleeping area, and on every level of the home. Carbon monoxide detectors are required when the home has fuel-burning appliances or an attached garage.
Differences Between Greenville County and Spartanburg County
While both counties enforce the same base building code, there are practical differences that affect the building process. Greenville County generally requires more detailed plan submissions and has adopted additional local amendments, particularly around stormwater management and land disturbance. If your lot is larger than a certain threshold or involves significant grading, you may need a formal stormwater management plan prepared by a civil engineer.
Spartanburg County tends to have a somewhat streamlined permitting process for straightforward residential projects, though complex builds still require thorough plan review. The inspection scheduling process and the specific inspectors you work with will differ between counties, and each office has its own preferred methods for communication and documentation.
Fee structures also differ. Greenville County calculates permit fees based on the estimated construction value using a standardized valuation table, while Spartanburg County uses its own fee schedule. Impact fees, which fund infrastructure improvements like roads and schools, may also apply depending on the jurisdiction and the specific development.
For lots that straddle county lines or sit near municipal boundaries, determining the correct jurisdiction is essential. Submitting a permit application to the wrong office wastes time and can cause confusion that ripples through the project timeline.
Timeline Expectations: From Application to Certificate of Occupancy
Understanding the permitting timeline helps you set realistic expectations for your overall project schedule. In Greenville County, plan review for a residential building permit typically takes two to four weeks from the date of a complete submission. If the plans require revisions based on reviewer comments, add another one to two weeks for resubmission and re-review. Spartanburg County operates on a similar timeline, though turnaround times can vary based on the volume of applications in the queue.
Once the permit is issued, the inspection process runs concurrently with construction. Each inspection is typically scheduled one to two business days in advance, and inspectors aim to visit the site on the scheduled date. If an inspection reveals an issue that needs correction, the builder makes the repair and schedules a re-inspection, which may add a few days to the schedule for that particular phase.
The final inspection and Certificate of Occupancy issuance usually happen within a few days of the builder calling for the final. However, all outstanding inspections for every trade must be passed before the CO can be issued, so coordination across all trades is essential in the final weeks of construction.

FAQ: Building Codes and Permits in Upstate SC
Do I need to apply for the building permit myself, or does the builder handle it?
In most cases, the builder handles the entire permit application process on your behalf. As the licensed contractor, the builder submits plans, pays fees, and serves as the responsible party for code compliance throughout the project. You will sign certain documents as the property owner, but the administrative work is managed by your builder.
What happens if an inspection fails?
A failed inspection means the inspector identified an issue that does not meet code requirements. This is not uncommon and is usually straightforward to resolve. The builder corrects the deficiency, which might be as simple as adding a missing nail plate or adjusting a duct connection, and schedules a re-inspection. A good builder treats inspection comments as opportunities to verify quality rather than as adversarial findings.
How much do building permits cost in Greenville County and Spartanburg County?
Permit fees vary based on the estimated construction value and the specific permits required. For a typical custom home, total permit and impact fees in Greenville County might range from $3,000 to $8,000 or more, depending on the project scope. Spartanburg County fees are generally in a similar range but calculated differently. Your builder will include estimated permit costs in the project budget during the planning phase so there are no surprises.
Can I start site work before the building permit is issued?
Limited site work such as clearing and rough grading may be possible with a separate grading or land disturbance permit, depending on the jurisdiction and the scope of work. However, no structural construction can begin until the building permit is issued. Attempting to build without a permit is a code violation that can result in fines, mandatory removal of unpermitted work, and significant project delays. Your builder will ensure all necessary permits are in place before any work begins.
