In Virginia, how close you can build to a property line depends almost entirely on the city or county where the property sits. State law sets a default that no building may sit within 35 feet of any street or roadway, but the distances to your side and rear property lines come from your local zoning ordinance — and those numbers change dramatically from one jurisdiction to the next.1Virginia Code Commission. Virginia Code Chapter 22 – Planning, Subdivision of Land and Zoning – Section 15.2-2279 Before you break ground on anything, you need to know your zoning district and read the specific setback requirements that apply to it.
Why There Is No Single Statewide Number
Two statutes give Virginia localities near-complete control over where on a lot you can build. Section 15.2-2279 lets any city, county, or town regulate house construction, establish minimum setbacks and side yards, and set minimum lot sizes. It also creates the 35-foot default distance from streets, though that default does not apply within a town that has already adopted its own setback ordinance.1Virginia Code Commission. Virginia Code Chapter 22 – Planning, Subdivision of Land and Zoning – Section 15.2-2279 Section 15.2-2280 adds broader zoning power over the size, height, bulk, and location of structures, and the dimensions of yards and open spaces. It explicitly allows lot-size variations based on whether public water or sewer is available, which is why rural parcels on wells and septic often carry larger minimums than lots on public utilities.2Virginia Code Commission. Virginia Code 15.2-2280 – Zoning Ordinances Generally
The practical result: a front setback of 15 feet may be normal in an older urban neighborhood, while a comparable residential lot in a suburban county could require 35 or 40 feet. Side-yard and rear-yard requirements show the same range. Fairfax County ties setback dimensions to zoning district in Article 2 of its ordinance,3Fairfax County. Learning About Your Lot – Zoning Districts, Yards, and Setbacks and a neighboring locality may use different district names and different distances for what looks like the same kind of lot. State law expects this variation — Section 15.2-2284 requires zoning ordinances to account for the existing character of the area, growth trends, community needs, and natural resource conservation.4Justia Law.

Never assume the rules from one Virginia locality apply anywhere else.
Finding the Actual Setback for Your Lot
The numbers you need are not in the state code. They’re in your local ordinance, and they turn on which zoning district your parcel falls in.
- Contact your locality’s planning or zoning office, or check the online zoning map, to identify your district classification. Everything else depends on this.
- Read the ordinance section for your specific district. Look for the front setback, side setbacks, and rear setback. Corner lots often have two “front” setbacks rather than one front and one side.
- Get a current boundary or house-location survey. This is the document that shows your lot lines against existing and proposed structures.
- Talk to the zoning office before you pour concrete. Many violations happen because the owner guessed at the lot line. Most localities also require a site plan review as part of the building permit process.
Skipping the survey is where most trouble starts. Fence lines, driveways, and old landscaping features are not property lines, and building to any of them is a gamble.
Sheds, Garages, and Other Accessory Structures
Detached garages, sheds, workshops, and similar buildings usually have their own setback rules, and those rules are often less restrictive than what applies to your house — but only up to a point, and the point is usually height.
Fairfax County illustrates the pattern. A freestanding accessory structure under 8.5 feet tall can sit anywhere in the side or rear yard with no minimum distance from the lot line. Between 8.5 and 12 feet, the structure must stay at least 5 feet from side and rear lines. Above 12 feet, the side setback matches the primary dwelling’s requirement for that district, and the rear setback must equal at least the structure’s height.5Fairfax County. Freestanding Accessory Structure Location Accessory structures are generally prohibited in front yards on lots of 36,000 square feet or less.
Other Virginia localities handle this differently. Some apply a single uniform setback for all outbuildings regardless of height; others follow the tiered approach Fairfax uses. One category is handled at the state level: temporary family health care structures used by a caregiver on the same property must meet the same setbacks as the primary dwelling.6Virginia Code Commission. Virginia Code 15.2-2292.1 – Zoning Provisions for Temporary Family Health Care Structures For anything else, check the accessory-structure section of your local ordinance — it’s almost always separate from the primary-dwelling section.
Building Closer Than the Rule Allows: Variances
If your lot’s shape, size, or topography makes strict compliance unreasonable, you can apply for a variance through the local board of zoning appeals. Every Virginia locality with a zoning ordinance has one of these boards, made up of five or seven residents appointed by the local circuit court for five-year terms.7Virginia LIS. Virginia Code 15.2-2308 – Boards of Zoning Appeals to Be Created
The board can only grant a variance if it finds all three of the following:
- Strict application of the setback rule would produce a genuine hardship tied to the property itself, not just inconvenience or added cost.
- The hardship is not shared by other properties in the same district and vicinity. If every lot on the street has the same problem, the ordinance is the wrong target.
- Granting the variance won’t substantially harm adjacent properties or change the character of the district.8Virginia LIS. Virginia Code 15.2-2309 – Powers and Duties of Boards of Zoning Appeals
The statute specifically contemplates lots whose exceptional narrowness, shallowness, shape, or topography at the time the ordinance took effect makes literal compliance effectively impossible. The standard is hardship “approaching confiscation,” not a preference or convenience. Self-created hardships, such as subdividing a compliant lot into pieces that no longer meet setbacks, will not qualify.
The process involves public notice and a hearing under the notification procedures in Section 15.2-2204, with abutting property owners notified by first-class mail. Expect at least several months from filing to decision. If the board denies your variance, you can appeal to the local circuit court, but the filing deadline is strict and missing it forfeits your right to review.
Apply early. Boards are far less sympathetic to a violation already built than to a thoughtful request made before construction.
What Happens If You Build Inside a Setback
Building within a setback without approval can trigger fines, court orders requiring you to modify or remove the structure, and problems that follow the property into any future sale.
Under Section 15.2-2209, localities can adopt a civil penalty schedule for zoning violations. Fines are capped at $200 for an initial violation and $500 for each subsequent notice, with each day of continued violation counting as a separate offense. Violations arising from the same facts can’t be charged more than once every 10 days, and total civil penalties from a single ongoing violation are capped at $5,000. Once penalties reach $5,000, the locality can prosecute the violation as a criminal misdemeanor instead.9Virginia Code Commission. Virginia Code 15.2-2209 – Civil Penalties for Violations of Zoning Ordinance
Fines are not the worst of it. A zoning administrator can seek a court order requiring abatement, meaning you may have to tear down, relocate, or modify the structure to bring it into compliance. Virginia has documented cases of owners cutting entire rooms off the front of a house after a variance was denied for construction built too close to the road.
The problem also survives into resale. An encroachment on a setback boundary can render a title unmarketable, letting a buyer walk away from the purchase contract without breach. Title insurers routinely flag setback issues found on surveys, and a lender may refuse to close on a mortgage when a survey shows a structure inside a required setback. Even when a deal closes, an unresolved violation becomes a disclosure item that lowers value and narrows the buyer pool. A survey done before construction is far cheaper than any of these outcomes.
Older Houses Already Inside a Setback
If your house was built legally and a later ordinance change put it inside a current setback, the building is a “nonconforming structure.” Virginia law lets these structures remain in use as long as the use continues and hasn’t been abandoned for more than two years, and as long as the building is kept in its existing structural condition.10Justia Law. Virginia Code 15.2-2307 – Vested Rights Not Impaired The locality can require compliance if you enlarge, extend, reconstruct, or structurally alter the building, which is worth knowing before you plan an addition to an older home.
Disaster damage gets special treatment. If a natural disaster damages the building, the locality may require repairs to reduce the nonconforming features where possible without a variance, but if the building can only be restored to its original condition, the owner has the right to do that. You have two years from the date of the disaster to begin repairs or rebuilding before the full current ordinance applies. Properties in federally declared disaster areas get an additional two years.10Justia Law. Virginia Code 15.2-2307 – Vested Rights Not Impaired
Nonconforming status is not permanent. Stop using the building for its nonconforming purpose for two years and you lose the right to resume that use.
