Arlington County Zoning Ordinance: Districts, Variances, and Penalties

The Arlington County Zoning Ordinance is the county’s land-use rulebook. It assigns every parcel to a zoning district, sets what can be built on that parcel and how it can be used, and routes any exception through a permit, variance, or site-plan process. Its authority comes from Virginia’s planning and zoning statutes under Title 15.2, Chapter 22 of the Code of Virginia, which lets localities regulate land use, building size, and density inside their boundaries.¹ Before you plan a addition, open a business at home, or list a spare bedroom, the ordinance decides what you’re allowed to do.

Find Your Zoning District First

Every property in Arlington sits inside a zoning district, and that district controls almost everything else. One-family residential districts like R-5 and R-6 are reserved primarily for single-family homes, each with its own minimum lot size (R-6 requires at least 6,000 square feet, for example).² The RA-series districts (RA8-18, RA6-15, and others) allow apartments and higher-density housing. Commercial and mixed-use districts permit offices, retail, restaurants, and often residential units on the same site. Specialized designations such as the S-3A Special District and the P-S Public Service District handle institutional and government uses.³

Your district appears on the official Arlington County Zoning Map, accessible through the county’s interactive GIS tool. Confirm the designation before spending money on plans. A separate framework, the Form-Based Code, governs the Columbia Pike corridor and regulates building form (height, placement, facade) rather than use categories; properties along the Pike often have that as an alternative path to conventional zoning.⁴

What You Can Build: Setbacks, Coverage, and Floor Area

Article 3 of the ordinance sets the physical envelope for any structure: how far it must sit from property lines, how tall it can be, and how much of the lot it can cover.³ Articles 4 through 6 layer on district-specific rules for public, residential, and multiple-family zones.

Setbacks catch homeowners off guard more than any other rule. In the R-6 district, side yards must total at least 18 feet, with a minimum of 8 feet on one side.⁵ Front yard requirements are calculated separately and can shift with lot configuration. Getting the numbers wrong is one of the fastest ways to have a permit denied, or to draw an enforcement action after construction has already started.

Two other limits work alongside setbacks. Lot coverage caps the share of your parcel that can be covered by buildings and impervious surfaces like driveways and patios. Floor Area Ratio (FAR) caps total building square footage relative to lot size. The two interact, and a project can pass one test while failing the other. Commercial zones enforce FAR limits tightly to manage traffic and infrastructure demand.

What You Can Do on the Property

Article 12 lists the specific activities allowed in each district and the conditions attached.³ Uses split into two buckets. By-right uses are automatic because they fit the district’s purpose, like a single-family home in a residential zone. Conditional uses need a Use Permit, meaning a public hearing and County Board approval to confirm the activity won’t harm neighboring properties.⁶ Daycare centers, private schools, and certain commercial activities in mixed-use zones commonly land in that second bucket.

Working From Home

Arlington’s home occupation rules let residents run a professional business from home, with caps on employees and client visits so the activity stays secondary to the residence. The permit fee is $82.⁷

Short-Term Rentals

Short-term rentals (Airbnb-style lodging for fewer than 30 consecutive days) are treated as an accessory use. The host must be the owner or tenant of the dwelling, and the dwelling must be the host’s primary residence.⁸ The accessory homestay permit is $110.⁷

Accessory Dwelling Units

Arlington allows one accessory dwelling unit (ADU) per lot in single-family residential zones, on parcels of at least 4,000 square feet. Detached ADUs can reach 1,000 square feet; attached units cap at 850. Owner occupancy isn’t required, which puts Arlington on the more flexible end among Virginia jurisdictions. The permit fee is $565, with a potential $376 parking survey fee.⁷

If Your Property Predates the Current Rules

When zoning changes, some properties end up out of compliance through no fault of the owner. A house built too close to a property line under older setbacks, or a shop in an area later rezoned residential, becomes a “legal nonconformity.” Arlington lets these continue on two conditions: the nonconforming feature hasn’t been discontinued for more than two years, and it hasn’t been expanded or enlarged.⁹

Break either condition and the nonconforming status is permanently lost; the property has to come into compliance with current zoning. For nonconforming uses in particular, altering or removing the nonconforming building also extinguishes the status.⁹ Virginia law carves out one important exception: if a building is damaged by a natural disaster or other act of God, the owner may rebuild it to its original condition, provided a building permit is obtained and work begins within two years (four years if the area is under a federal disaster declaration).¹⁰

When You Need a Variance

If strict application of a dimensional rule creates a real hardship tied to your specific property, the Board of Zoning Appeals (BZA) can grant a variance. The BZA can modify lot dimensions, coverage, bulk, height, setbacks, and building placement.¹¹

To qualify, you have to show a hardship rooted in a physical condition of the property or its improvements, plus at least one of the following:

Strict application of the ordinance would unreasonably restrict use of the property.
The hardship comes from a physical condition that existed when the ordinance took effect.
The variance is a reasonable modification for a person with a disability.

Beyond that threshold, the BZA must also find you acquired the property in good faith and didn’t create the hardship, that neighbors won’t be substantially harmed, that the issue isn’t so widespread that a broader amendment would fit better, and that the variance won’t effectively change your permitted use or zoning classification.¹¹ That last point matters more than people expect. A variance adjusts dimensional standards. It doesn’t unlock a use the ordinance doesn’t allow in your district.

Fees depend on what you’re asking for. A modification to an existing one-family home starts at $805 for the first ordinance subsection involved, with $163 for each additional subsection. A variance for a new single-family dwelling starts at $4,179. All other uses begin at $5,779.⁷

How to Apply

All zoning applications go through Permit Arlington, the county’s online portal. You create an account, pick the application type, upload plans and supporting documents, and pay electronically. The system handles building permits, BZA variance and use permit applications, and other zoning requests.¹²

Most applications need a certified survey plat showing accurate property boundaries and existing structures, along with detailed site plans showing proposed changes with exact dimensions. BZA applications also require a statement of justification explaining the hardship, a disclosure statement identifying anyone with a financial interest in the property, and evidence of neighborhood outreach.¹¹

The technical rules for uploads are strict. Each plan sheet must be a separate PDF; bundled multi-page drawing sets are rejected. Files cannot be encrypted or password-protected. Every sheet needs a 3-inch by 3-inch blank space in the upper-right corner for the county’s approval stamp.¹³

Common Fees

From the FY2026 fee schedule:

Home occupation permit: $82
Accessory homestay permit: $110
Zoning verification permit: $218
ADU permit: $565 (plus a potential $376 parking survey fee)
BZA variance for existing home modification: $805 for the first subsection
County Board Use Permit (Type I): $7,227
County Board Use Permit (Type III): $14,069, plus a $6,207 DES fee

A 10% automation enhancement fee is added to all charges.⁷

What Violations Cost

Arlington starts with civil penalties and can escalate to criminal prosecution. The first violation is $200. Each subsequent violation can reach $500, and no person can be cited more than once in any 10-day period. Total civil penalties for all violations arising from the same set of facts are capped at $5,000.¹⁴

Once civil penalties hit $5,000, the county can prosecute criminally. A conviction is a misdemeanor punishable by a fine of $10 to $1,000. If the violation continues past the compliance deadline, each subsequent 10-day period is a separate misdemeanor carrying fines of $100 to $1,500.¹⁴ Virginia’s statewide penalty framework mirrors those caps at $200 for an initial summons and $500 for each additional one.¹⁵

Violations in historic overlay districts can be much steeper: up to twice the assessed market value of the property, structure and land included. The Zoning Administrator can also seek inspection warrants from a magistrate on probable cause that a violation exists.¹⁴

Federal Limits the Ordinance Can’t Cross

Two federal statutes constrain how far Arlington’s zoning can reach. The Religious Land Use and Institutionalized Persons Act (RLUIPA) bars zoning rules that place a substantial burden on religious exercise unless the government proves the burden serves a compelling interest by the least restrictive means.¹⁶ A rule that treats a church, mosque, or synagogue less favorably than a comparable secular assembly gives the religious institution grounds to challenge it.

The Fair Housing Act bars zoning practices that discriminate based on race, color, religion, sex, national origin, familial status, or disability. Arlington cannot use zoning to exclude group homes for people with disabilities from residential neighborhoods, deny a permit based on who is expected to live in a development, or refuse a reasonable zoning accommodation for someone with a disability.¹⁷ These guardrails rarely surface in routine permit work, but they set outer bounds on any part of the ordinance.
