Jump To The Permit Details That Matter

In North Carolina, most residential building permits require a site plan (often called a plot plan) showing property lines, existing and proposed structures, setbacks, easements, and floodplain information. The North Carolina Residential Code (2018 Edition) governs residential construction, and local building departments enforce their own specific requirements. Homeowners can prepare their own site plans for many small projects, but some jurisdictions require plans sealed by a North Carolina‑licensed surveyor or design professional. Always verify with your local building department.

Our site plan creator webtool is for preliminary, conceptual site plans where local rules allow homeowner or contractor‑prepared drawings. It is not a licensed survey or sealed engineering plan. Always verify requirements with your local building department.

North Carolina Permit Context: What Makes It Different

North Carolina has 100 counties and over 550 municipalities, each with its own building department, zoning code, and submission requirements. Unlike some states with a single state‑level building department, North Carolina delegates plan review and inspection authority to local jurisdictions approved by the NC Building Code Council.

Key facts about North Carolina permits:

  • The North Carolina Residential Code (2018 Edition) is the statewide standard, based on the International Residential Code
  • Local jurisdictions can have additional requirements beyond the state code
  • Owner‑builders can pull permits for their own homes without a contractor’s license
  • General contractors must be licensed by the NCLBGC for projects of $40,000 or more
  • Floodplain permits require certified drawings sealed by a licensed professional
  • FEMA Elevation Certificates are required for buildings in the 100‑year floodplain

North Carolina’s “owner‑builder” rule is a significant advantage for DIY homeowners. If you’re building or altering your own home, you don’t need a general contractor’s license — provided you obtain all required permits and occupy the home for at least 12 months after completion. This makes North Carolina one of the more homeowner‑friendly states for small residential projects.

Contractor licensing thresholds:

  • $40,000 or more: General contractor license required
  • $30,000 or more: Lien agent form and Worker’s Compensation Affidavit required
  • Trade licenses: Required for electrical, plumbing, and mechanical work regardless of project size

What North Carolina Building Departments Ask For On A Site Plan

Based on official checklists from Greensboro, Wake County, Johnston County, Durham, and Guilford County, a site plan (or plot plan) for a residential permit typically includes:

Element What to Show Why It Matters
Property boundaries Lot lines with dimensions and road frontage Establishes where your property starts and ends
APN / PIN Parcel identification number or tax ID Required for all applications
Existing and proposed structures Building footprints with overall dimensions Shows what exists and what you're adding
Setbacks Required and proposed setbacks from property lines Most common rejection reason — must match your zoning district
Easements Location, width, and purpose of utility, drainage, and access easements You can't build on easements
Floodplain information FEMA 100‑year flood fringe and floodway lines Required for properties in flood zones
Driveways and parking Location, width, surface material Required for access and impervious surface calculations
Utilities Well, septic tank, drain field, sewer, water connections Shows how the property connects to utilities
Impervious surfaces Square footage and percentage of lot Many jurisdictions have impervious surface limits
Stormwater management Location, dimensions, capacities Required for larger projects
Erosion control Silt fencing and construction entrance Required for land‑disturbing activities
North arrow & scale Orientation and measurement reference Required on every plan
Title block PIN, subdivision name, north arrow, scale, preparer name, signature, date Identifies the project and responsible party

Common scale requirements:

  • Parcels less than 5 acres: 1″ = 20′, 30′, 40′, 50′, 60′, or 100′ on paper no larger than 11″ × 17″
  • Parcels 5 acres or more: 1″ = 100′, 200′, 300′, 400′, or 500′
  • Minimum scale for Wake Forest: 1/8″ = 1′

Paper size:

  • Ledger size maximum for Greensboro
  • 11″ × 17″ maximum for Johnston County

Plot Plan vs. Site Plan: Same Thing

North Carolina jurisdictions use both terms interchangeably:

Term Where Used
“Plot Plan” Guilford County, High Point, Greenville, Durham
“Site Plan” Greensboro, Wake County, Johnston County, Wake Forest
“Preliminary Site Plan” Required before permits are issued
“Final (As‑Built) Site Plan” Required before Certificate of Occupancy in some cases

Both terms refer to the same scaled drawing showing your property, structures, and proposed work.

When You Must Have A Sealed Plan

North Carolina has specific rules about when a site plan must be prepared and sealed by a licensed professional:

Generally required:

  • Site Plans for new residences shall be signed and sealed by an NC‑licensed land surveyor or design professional
  • Some jurisdictions require a sealed survey for all projects
  • Properties within a floodplain require a certified drawing sealed by a licensed Professional Engineer or Professional Land Surveyor

May be accepted without a seal:

  • Detached accessory buildings (sheds, garages, carports) — some jurisdictions
  • Decks and porches complying with NC Residential Code Appendix M
  • Minor, non‑structural alterations
  • Where the applicant can draw the plan in a “detailed and legible manner” and it is approved by Planning Department Staff

> If you draw the plot plan yourself, be sure to sign and date it, and include contact information.

3. What’s the difference between a site plan and a survey in North Carolina?
