Arlington County CPN-FBC District Placement and Setback Standards

Jurisdiction: Arlington CountyCode Version: March 14, 2026

Placement and setback requirements for the CPN-FBC: Columbia Pike Neighborhoods Form Based Code district in Arlington County are primarily governed by the physical form and design standards found in Appendix B of the Zoning Ordinance. In this district, traditional numerical setbacks are replaced by "Build-to lines" and specific form-based regulations intended to define neighborhood character and prioritize pedestrian-oriented development [§11.2.1.B, §11.2.3]. For property owners who do not elect to use the Form Based Code, the development retains the standard setback and yard requirements of the underlying zoning district, such as R-5 or R-6 [§11.2.2.B].

Governing Regulatory Framework for CPN-FBC

The CPN-FBC: Columbia Pike Neighborhoods Form Based Code is an optional zoning tool in Arlington County. Because it is a Form Based Code (FBC), building placement is dictated by the desired physical outcome of the streetscape rather than simple minimum distances from property lines.

Regulatory Aspect CPN-FBC Requirement Standard Ordinance Equivalent
Primary Authority Appendix B (Neighborhoods Form Based Code) Article 3 (Density and Dimensional Standards)
Placement Method Build-to Lines (defining the block face) Setbacks (minimum distance from lines)
Primary Focus Physical Form and Neighborhood Character Bulk, Coverage, and Placement
Applicability Optional (Owner must file application) Mandatory (Underlying District)

Build-to Lines and Placement

In the CPN-FBC district of Arlington County, building placement is typically established through a Build-to line. As defined by the Arlington County Zoning Ordinance, a build-to line is established along a street frontage, extending the full width of the lot, to define the block face and establish exactly where the building must be placed [§3.1.2].

For properties within the CPN-FBC district that have not been redeveloped using the Form Based Code, all use limitations and dimensional standards of the underlying zoning district apply [§11.2.2.A].

Underlying District Standards (Default Requirements)

Properties eligible for the CPN-FBC district in Arlington County include those originally zoned R-5, R-6, R2-7, R15-30T, RA14-26, RA8-18, RA7-16, RA6-15, C-1, or C-O [§11.2.2.A]. If the owner does not utilize the optional CPN-FBC standards in Appendix B, the following default setbacks generally apply to the residential structures:

Placement Type Default Underlying Residential Requirement Ordinance Section
Front Setback The larger of 50 feet from the street centerline or 25 feet from the street right-of-way line. [§3.2.6.A.1(d)]
Side Yard 10 feet (standard), with an additional foot for every 2 1/2 feet of building height above 25 feet. [§3.2.6.A.2(e)]
Rear Yard 25 feet (standard) for interior lots. [§3.2.6.A.2(e)]

Specific Use and Design Requirements
