Setbacks & Height Limits in Winston-Salem

This guide explains the basic setback and height rules that apply to residential construction in Winston-Salem. Winston-Salem and Forsyth County share a joint Unified Development Ordinance (UDO) administered by the City-County Planning Board, so the same district standards apply inside the city limits and in unincorporated Forsyth County.

These numbers depend on your exact zoning district, overlay zones, and lot geometry, so always confirm with Winston-Salem Planning & Development Services before finalizing plans.

What Are Setbacks?

A setback is the minimum required distance between a building and a lot line. Setbacks are measured from the property line to the nearest point of the building (typically the wall, but eaves, bay windows, and chimneys can have their own rules under the UDO).

The Winston-Salem/Forsyth County UDO specifies front, side, and rear setbacks separately for each zoning district. Corner lots have two "front" setbacks (one per street frontage) and typically one interior side and one rear.

Typical Residential Setbacks

For the most common single-family residential districts in Winston-Salem, the UDO requires:

Very low-density RS-40 districts apply where large-lot suburban or rural character is preserved and carry larger minimum lot sizes and deeper setbacks than RS-20. Higher-density RM-8 and RM-12 multi-family districts and the business and industrial districts each have their own schedules — check the UDO district chapter for specifics.

Corner lots typically must observe a street side setback that is larger than the interior side setback. Double-frontage lots observe a front setback on each street frontage.

Height Limits

Maximum building height in Winston-Salem's RS-9, RS-12, and RS-20 single-family residential districts is 35 ft, measured per the UDO definition of building height. Multi-family RM districts and nonresidential zones use separate height limits that may permit greater height, sometimes tied to additional setback or buffer requirements.

Height rules can be modified by:

• Historic Overlay Districts — Winston-Salem has several locally designated historic districts where the Historic Resources Commission reviews height, massing, and compatibility
• Planned Residential Developments (PRDs) — approved PRD site plans may establish their own height envelope
• Airport approach zones — properties near Smith Reynolds Airport are subject to additional height limits
• Steep slopes and watershed overlays — environmental overlays may impose additional limits

Lot Coverage

Beyond setbacks and height, lot coverage limits the percentage of the lot that may be occupied by buildings and certain impervious surfaces. The UDO sets coverage maximums by district. Pools, driveways, and open decks are often treated separately — check the UDO definition that applies to your district.

Common Exceptions and Encroachments

The UDO allows certain features to project into required setbacks. Typical allowances include:

• Eaves, gutters, and cornices (limited projection)
• Chimneys
• Uncovered porches, stoops, and steps
• Air conditioning condensers (subject to location rules)
• Bay windows (limited projection)

Fences, retaining walls, and accessory structures (including detached garages and sheds) have their own rules in the UDO's accessory structure section.

State ADU Note

North Carolina does not preempt local ADU standards with a statewide override. ADUs in Winston-Salem are governed entirely by the Winston-Salem/Forsyth County UDO. See the ADU rules page for this city.

How to Look Up Your Specific Requirements

1. Find your zoning district — use the City-County Planning GIS map or call Winston-Salem Planning at (336) 747-7057
2. Read the district regulations — the UDO district chapter lists setbacks, height, lot coverage, and any density limits
3. Check for overlays — historic districts, watershed overlays, airport overlays, and PRDs can modify base rules
4. Ask planning staff — the City-County Planning Board offers pre-application guidance before you commit to design

Variances

If your project cannot meet the strict letter of the UDO, you may apply for a variance from the Winston-Salem Board of Adjustment — a formal request to deviate based on hardship specific to your lot. Variances are discretionary and require a public hearing. See the Variance Application Guide for the general process.
