Forsyth County, NC Site Plans — Navigating the Unified CSS Portal

Forsyth County, home to Winston-Salem and a population of over 380,000, offers one of the most streamlined permitting experiences in North Carolina's Piedmont Triad. Instead of bouncing between city and county offices, residents in Winston-Salem and unincorporated Forsyth County deal with a single, unified Inspections Division. They even share a single Unified Development Ordinance (UDO) administered jointly by the City-County Planning Board. (The only major exception is the portion of High Point that bleeds into the county, which operates independently). While the bureaucracy is unified, the requirements remain strict. To pull a permit for an accessory structure, deck, pool, or addition, you must upload a site plan to the CSS (Customer Self-Service) portal. This plan must clearly delineate your property lines, all existing structures, and the proposed new construction. Most importantly, it must prove compliance with local zoning setbacks. The county allows homeowners to prepare their own site plans for standard residential projects, provided they are accurate and drawn to scale, saving residents the cost of a surveyor for simple backyard improvements.

Jump To The Permit Details That Matter

In Forsyth County, North Carolina, building permits are managed by the unified Winston-Salem/Forsyth County Inspections Division. A site plan is required for most residential projects, including decks, pools, additions, and accessory structures with any dimension exceeding 12 feet. The site plan must be drawn to scale and show property lines, the existing home, the proposed structure, and all setback distances. Homeowners are permitted to draw their own site plans for these standard projects. All applications and site plan PDFs must be submitted digitally through the county's Customer Self-Service (CSS) portal. A licensed surveyor is generally only required for new home construction or if property lines are disputed.

If you have ever tried to pull a permit in a county where the city and county governments fight over jurisdiction, you will appreciate Forsyth County.

The Winston-Salem/Forsyth County Inspections Division is a unified agency. They share the same rules (the UDO) and the same online submission system (the CSS portal). But just because the process is centralized doesn't mean it's lenient. If you are building a deck or a shed, you must submit a site plan that clearly proves you are following the rules.

Do You Need a Site Plan for a Small Permit in Forsyth County?

Yes. Whether you are in the heart of Winston-Salem or out in rural Forsyth County, if you are applying for a residential building permit, a site plan (or property survey) is a required document.

The county allows homeowners to prepare these plans for standard projects, but they must include specific details:

  • Property lines with dimensions
  • The existing home and all other existing structures
  • The proposed structure (patio, deck, detached garage, shed)
  • Setbacks (exact distances from the proposed structure to the property lines)
  • Easements and other known restrictions
  • A North arrow and an indicated scale
  • Title block with your address, name, and Parcel ID (PIN)

Who Runs Into This in Forsyth County

  • Homeowners adding a deck who submit a framing plan, but forget to include a site plan showing how close the deck gets to the property line.
  • Shed buyers who purchase a 12'x14' shed and assume it doesn't need a permit, running afoul of the state-wide 12-foot dimension rule.
  • Properties on septic that submit a site plan without getting the required sign-off from the Forsyth County Health Department.
  • High Point residents who mistakenly try to use the Forsyth County CSS portal (the portion of High Point in Forsyth County is handled by the City of High Point).

What Needs a Site Plan in Forsyth County

  • Fence permit site plan — Fences exceeding 6 feet in any dimension require a building permit. Smaller fences may still require zoning approval. (Note: Historic districts require a separate Certificate of Appropriateness).
  • Shed permit site plan — Required. Any accessory building with any dimension exceeding 12 feet requires a permit and a site plan showing a minimum 3-foot setback.
  • Deck permit site plan — Required. A scaled site plan showing property lines and setbacks must accompany the framing details.
  • Patio permit site plan — Required for covered patios or large paved areas to check impervious surface limits.
  • Pool permit site plan — Required. Must show pool location, equipment, barriers, and setbacks.
  • Addition permit site plan — Required. Must show the expanded footprint and all updated setbacks.
  • Retaining Walls — Walls over 6 feet (measured from the bottom of the footing) require a permit and site plan.

Why This Trips People Up in Forsyth County

The 12-Foot Rule. Like the rest of North Carolina, Forsyth County enforces the NC Residential Code rule regarding accessory structures: if any single dimension exceeds 12 feet, a building permit is required. A 12x12 shed might be exempt from a building permit, but a 10x14 shed requires one (and thus, requires a site plan).

The CSS Portal PDF Requirement. Forsyth County has moved almost entirely to digital submissions via the Customer Self-Service (CSS) portal. You cannot easily drop off a hand-drawn sketch on notebook paper. You must upload a clean, legible PDF of your site plan.

Septic Sign-offs. If you are on a septic system, you cannot just submit your site plan to the Inspections Division. You must also route it through the Forsyth County Health Department to ensure your new deck or pool isn't going to crush your drain field.

Zoning and Setbacks in Forsyth County

Setbacks are governed by the unified Winston-Salem / Forsyth County Unified Development Ordinance (UDO).

While you must verify your specific zoning district, general guidelines include:

  • Side yard: Typically 10 feet for primary structures.
  • Rear yard: Typically 25 feet for primary structures.
  • Accessory structures (Sheds/Garages): Generally must maintain a minimum setback of 3 feet from side and rear property lines. However, if the structure is over 15 feet tall, it must be at least 10 feet from the property lines.

Note: Building setback variances are very difficult to get and may not exceed 20% by law.

Where This Tool Fits — and Where It Doesn't

Situation Best path
Shed, deck, pool, or standard addition SitePlans.ai for the required homeowner-drawn site plan
Winston-Salem city limits SitePlans.ai (the unified agency accepts the same plans)
New home construction Licensed Civil Engineer/Surveyor required
Property with unclear boundaries Licensed Land Surveyor required
Historic District properties SitePlans.ai for layout; verify strict aesthetic rules with Historic Resources

What This Doesn't Replace

SitePlans.Ai helps create preliminary, conceptual site plans for residential projects where the Forsyth County Inspections Division allows homeowner-prepared drawings. It is not a licensed land survey or sealed engineering drawing. If you are building a new dwelling, applying for a Site Development Permit, or building very close to a disputed property line, you must hire a licensed North Carolina surveyor.

Common Mistakes That Delay Forsyth County Permits

  • Forgetting the Health Department — Uploading a site plan for a pool to the CSS portal without getting prior septic approval from the Health Department.
  • Ignoring the 12-foot rule — Building a 14-foot shed without a permit, resulting in code enforcement action.
  • Violating the height rule — Placing a 16-foot tall detached garage 3 feet from the property line (structures over 15 feet tall require a 10-foot setback).
  • Poor PDF quality — Taking a blurry cellphone photo of a pencil sketch and trying to upload it to the CSS portal.
  • Missing existing structures — Drawing the new shed, but failing to show the existing house on the site plan.
