Washington County One statewide code, no local amendments

Barndominium Builders in Washington County, VA

Washington County, Virginia is the state's south-western land market: 169,761 acres in farms, 46.2% of the county, and a median farm of 40 acres, with 766 of its 1,358 farm operations smaller than 50 acres. It is also limestone country. The county's own Comprehensive Plan says limestone is the dominant rock under the valley and names Washington County as a Virginia county containing karst topography, and the county maps its own sinkholes. Two things decide how a build here starts: which district the parcel sits in, and which of four building departments issues the permit.

Building conditions in Washington County

The building code itself is the same in every Virginia locality, and no county, city or town may amend it. What changes from one to the next is who issues the permit and inspects the work, what that office charges, how the parcel is zoned, and the Table R301.2 design criteria the locality publishes — the 2021 Virginia Residential Code prints that table blank, with the instruction that additional criteria shall be established by the local jurisdiction. Those local numbers are what your drawings have to satisfy.

Four building departments, one county
The county permits and inspects in the unincorporated county and in the Towns of Damascus and Glade Spring, plus the Washington County portion of Saltville. Abingdon is not on that list because Abingdon runs its own building department, with its own published fee schedule and its own seven-member board of building code appeals. County Code section 14-2 explains why: a municipality that has no building department of its own must enter an agreement with the board of supervisors for enforcement. And the independent City of Bristol, Virginia next door is a separate jurisdiction the county reaches into not at all - although Bristol mailing addresses run well into the county, so a postal address proves nothing about which office issues the permit.

Zoning and the building permit follow different lines
The county's own zoning page states that all parcels lie in one of sixteen zoning districts, and that the Towns of Abingdon, Damascus, Glade Spring and the Washington County portion of Saltville each have their own town zoning ordinances which the county ordinance does not reach. So in Damascus and Glade Spring the county issues the building permit while the town issues the zoning approval. The county's own residential permit application routes the site plan to three different offices for that reason.

Roughly half the county is karst
A Virginia Tech study for the Virginia Speleological Survey put Washington County at 50 percent karst terrain in 2003 - tied with Giles, Highland, Russell, Scott and Shenandoah, and behind only Lee at 60 percent. The county says the same thing in its own words: its Comprehensive Plan records that limestone is the dominant rock underlying the valley and that Washington County is identified as a Virginia county containing karst topography. Virginia Energy puts it plainly for the region: most of Virginia's karst region follows Interstate 81, and twenty-seven of Virginia's counties lie in that zone.

Karst here is a prudence problem, not a permit gate
Nothing in Washington County's zoning ordinance requires a geophysical or geotechnical study for karst. The word appears three times in the whole county Code and never in Chapter 66: once in section 30-205, which requires a stormwater management plan to show the features stormwater discharges to including karst features if present, and twice in the Comprehensive Plan. DCR says the same for the state - few other legally binding mechanisms established for protection of karst features exist in Virginia - and its own Virginia Karst Geology Map carries a note saying it is not meant to provide information for land use decisions at the county or municipal locality scale. Nobody will stop a buyer building over a void. The Virginia Cave Board's Karst Assessment Standard Practice sets the benchmark for who should look: a professional engineer with a geotechnical civil specialty and at least five years in karst geology or hydrology, or a certified professional geologist with five years in karst studies, signing and sealing a statement of qualifications.

The A-1 lot, and where a shop with living quarters lands
A-1 Agricultural, Limited takes two acres, or one acre where public water is available, with 150 feet of frontage, a 35-foot street setback, side yards of 15 feet each that must total 50 feet, and a 35-foot rear yard. Accessory structures may come within five feet of a property line - but section 66-1 defines an accessory building as one where no such accessory structure shall be used for housekeeping purposes. Put a kitchen and a sleeping room in a detached shop and it meets the ordinance's definition of a dwelling unit, so it takes the dwelling's yards, not the five-foot accessory line. The attached-shop form avoids the question entirely: section 66-297 says garages, carports, porches and stoops attached to the main building are considered part of the main building.

The permit fee doubles at the Abingdon town line
The county charges on a sliding valuation scale: 370 dollars for the first 100,000 of valuation plus 2 dollars per additional 1,000 in the 100,001 to 500,000 band, plus a 2 percent DHCD levy on all permits, plus a 5 dollar zoning permit fee collected with it. Abingdon charges a 25 dollar base plus 5 dollars per 1,000 of value, capped at 35,000. On the two jurisdictions' own published schedules a 300,000 dollar valuation comes to 785.40 dollars in the county and 1,525 dollars in the town. Both jurisdictions also penalise starting early: the county adds a review fee equal to the whole permit fee on top of it, and Abingdon doubles the fee.

The land that is actually here
169,761 acres in farms - 46.2 percent of the county, seventh most farm acreage of any Virginia locality. The median farm is 40 acres and 766 of the county's 1,358 farm operations are smaller than 50 acres, a majority. Density is 96 people per square mile across 561 square miles, and the population has been flat rather than falling: 53,357 on 1 July 2025.

Elevation sets the wind speed, and this county spans the line
Virginia amends the residential code at 13VAC5-63-210 so that wind speeds for localities near mountainous terrain are set by elevation: 140 mph ultimate at or above 4,000 feet and 110 mph below it. The county's Comprehensive Plan gives its range as 1,330 feet near Mendota to 5,524 feet at the summit of Whitetop Mountain, the second highest peak in Virginia. Ninety-five percent of the county is Valley and Ridge; the Whitetop corner is Blue Ridge. Very few Virginia counties contain ground on both sides of that 4,000-foot line, and this is one of them.

The county publishes no Table R301.2
The 2021 Virginia Residential Code prints Table R301.2 blank, with em-dashes in every cell and the instruction that additional criteria shall be established by the local jurisdiction. Washington County has not published one - not on its building department pages, not in its Code, and not on its permit application. So the ground snow load, frost depth and seismic design category for a parcel here come from the county Building Official, and no figure should be taken off a national map or borrowed from a neighbouring county. Ask by name: Building Official Jason McCall, (276) 525-1340.

Eighteen months in the camper, and then it goes
Section 66-205 lets one camper trailer, recreational vehicle or manufactured home sit on the same lot as the permanent dwelling being built, in districts where manufactured homes are permitted without a special exception. It must be removed within 30 days of the certificate of occupancy and no later than 18 months after the building permit was issued - 90 days after the certificate where the permanent dwelling is a manufactured or modular home. The county publishes a dedicated RV application form for it.

Most of the flood-prone ground has no published flood elevation
The county participates in the National Flood Insurance Program and its Flood Hazard district rules sit in Chapter 66, Article V, Division 15, with the FEMA maps folded into the official zoning map. The county's own zoning page states that most flood-prone areas of Washington County are designated as Zone A - an approximate zone, which means no base flood elevation has been published for it. On those parcels the designer has to establish the elevation rather than read one off a map, which is why the county links FEMA's guide to managing floodplain development in approximate Zone A areas. Manufactured homes are prohibited in the FH district outright.

A well setback most rural parcels here trigger
Virginia's private well regulation sets a 50-foot separation between a well and a property line adjoining a property of three acres or more used for an agricultural operation, instead of the ordinary five feet. In a county 46.2 percent of whose land is in farms, most rural parcels adjoin one. Relief needs either a notarised letter from that neighbour, recorded and indexed in the circuit court land records, or a professional's certification that no complying location exists. On sloping ground a second rule compounds it: within a 60-degree arc directly downslope of a septic system the minimum separation increases by 25 feet for every 5 percent of slope, which is usually why the well ends up uphill of the house.

12VAC5-630-380, Well location, Table 1 and subsection C, as amended effective 6 November 2024

Septic is sized on bedrooms, and the shop counts for nothing
Virginia sizes a drainfield at 75 gallons per day per person and two persons per bedroom - 150 gallons per bedroom - with no living-area band and no row anywhere in the table for a shop, a garage or a barn. A four-bedroom barndominium is 600 gallons a day whether the shop is 1,200 square feet or 4,000. What does move the number is soil: 12VAC5-610-490 assigns a design percolation rate by soil texture, and clay sits in Texture Group IV at 91 minutes per inch or more, past the 45-minute threshold that makes a 50 percent reserve area mandatory. The Chesapeake Bay Preservation Act's stricter 100 percent reserve does not apply here - that Act reaches a statutory list of localities and Washington County is not on it.

Two working days, and then a third party can inspect
In a rural county with one building official, scheduling is the risk. The building code answers it: where the building official is unable to make a required inspection within two working days of a request or an agreed date, the official shall accept third-party reports for review, and must reject one in writing within two working days if there is cause. Every building official in Virginia is also required to have a written policy setting the minimum acceptable qualifications for third-party inspectors. That policy is a document worth asking the county for by name at the start of a project.

13VAC5-63-130, Virginia Uniform Statewide Building Code Sections 113.7 and 113.7.1

Mount Rogers land is zoned against living on it
The Highland Recreation district covers the Mount Rogers National Recreation Area inside the county, with boundaries the ordinance makes concurrent with the NRA's. Its statement of intent says it is not intended that these lands should develop intensively for residence, either yearround or second homes. Minimum lot is two acres, or one with public water, with a 50-foot street setback, 150 feet of frontage and 25-foot side yards. Land in the Konnarock and Whitetop corner is worth checking against that before an offer.

Code of the County of Washington, Virginia, Chapter 66, Article V, Division 2, sections 66-221 to 66-227 (Municode)

The small rules that only show up on the form
A zoning permit has to be in hand before construction starts, and the certificate of occupancy is applied for at the same time. A permit will not issue on a parcel the zoning office considers nonconforming until the division or boundary adjustment is approved. A land-disturbing permit and an erosion and sediment control plan are required past 10,000 square feet of grading, with an agreement in lieu accepted for residential. Where main water pressure exceeds 80 psi the county requires a pressure-reducing valve, enforced by the county building inspector. And after the footing inspection passes, the county collects GPS data and assigns the 911 address through the Department of Emergency Services.

Below the slab

The expensive surprises are in the ground, not the building

What moves a Virginia budget is usually below grade, and it is soil rather than rock. Five localities already treat a soil answer as a condition of the permit rather than a recommendation — Fauquier, Chesterfield, Isle of Wight, Madison and Culpeper each require a soil report, an engineered foundation design, or both before the footings are approved. Chesterfield asks for one on every new house with no opt-out, on its own published reasoning that small amounts of shrink-swell soil may turn up anywhere in the county. Virginia Energy puts the same point bluntly: standard homeowner's insurance does not cover damage from expansive or compressive soils. Along the Interstate 81 corridor the question changes shape entirely — Virginia Energy counts twenty-seven Virginia counties in the karst zone that follows that road, where what matters is what is under the slab rather than what the slab sits in, and karst does not stay west of the Blue Ridge: Loudoun County publishes karst terrain of its own, on the other side of it. The same ground then sizes the septic system, because 12VAC5-610 works from bedrooms and soil texture — 150 gallons a day per bedroom, with no row in the table for a shop, a garage or a barn at all, and clay assigned to the slowest texture group at 91 minutes per inch or worse, past the 45 minutes per inch that makes a reserve drainfield mandatory. The soil that needs a foundation engineer multiplies the drainfield. So the site work, the foundation and the drainfield get resolved together rather than one at a time. We price the dirt before we price the building.

Building in Washington County: common questions

6 questions we get asked most often about building in Washington County. If yours is not on the list, ask it directly.

Start your project
Who issues the building permit for a barndominium in Washington County, Virginia?
It depends which side of a town line the parcel sits on, and the answer is not the one most people assume. The Washington County Department of Building & Development Services permits and inspects in the unincorporated county and, unusually, inside the Towns of Damascus and Glade Spring and the Washington County portion of Saltville. The Town of Abingdon is the exception: it runs its own building department, publishes its own fee schedule and seats its own board of building code appeals, so a build inside Abingdon's limits is the town's permit from start to finish. County Code section 14-2 sets out the mechanism - a town with no building department of its own contracts with the board of supervisors for enforcement. Zoning then splits differently again: the county zoning ordinance does not apply inside Abingdon, Damascus, Glade Spring or the county's part of Saltville, each of which administers its own. So in Damascus or Glade Spring the building permit is the county's and the zoning approval is the town's. Finally, the City of Bristol, Virginia next door is an independent city - a county equivalent in no county at all - and Washington County has no authority inside its limits. Watch for the postal trap: Bristol, VA mailing addresses reach well into the county, including the health department office that handles the county's septic permits, so an address is not evidence of jurisdiction.
How much of Washington County is karst, and does anyone make me check?
About half of it, on the best county-level figures available - a 2003 Virginia Tech study working from Virginia Speleological Survey data put Washington County at 50 percent karst terrain, level with Giles, Highland, Russell, Scott and Shenandoah and behind only Lee. The county agrees in its own Comprehensive Plan, which records that limestone is the dominant rock underlying the valley and names Washington County as a Virginia county containing karst topography, and which carries a Flood Hazard, Slope and Sinkholes map showing mapped sinkholes alongside slopes over 20 percent. What nobody does is make you look. Karst appears three times in the entire county Code and never in the zoning chapter: the only operative mention is section 30-205, which requires a stormwater management plan to identify karst features if present. That is a drainage obligation, not a foundation one. DCR states that few other legally binding mechanisms established for protection of karst features exist in Virginia, and it disclaims its own statewide karst map as not meant for land use decisions at the county scale. So the investigation on a limestone parcel here is a decision, not a requirement - and the county's own Comprehensive Plan gives the practical reason to make it, banding grading cost by depth to rock and marking some ground simply as not developable. The Virginia Cave Board's Karst Assessment Standard Practice sets the standard for who should do the work: a professional engineer with a geotechnical civil specialty and five or more years in karst geology or hydrology, or a certified professional geologist with five years in karst studies, signed and sealed.
What wind speed and snow load do I design to here?
The honest answer is that Washington County has not published a filled-in Table R301.2, so there is no county ground snow load, frost depth or seismic design category to quote - and no figure should be lifted off a national map or borrowed from a neighbouring county to fill the gap. The 2021 Virginia Residential Code prints that table blank on purpose, with the instruction that additional criteria shall be established by the local jurisdiction, so those numbers come from the county Building Official for the parcel. Wind is different, because Virginia writes its own rule. The state amendment at 13VAC5-63-210 sets wind speed by elevation for localities near mountainous terrain: 140 mph ultimate at or above 4,000 feet and 110 mph below it, with the commercial code using 142 and 116 V mph for the same idea. Washington County spans that line. Its Comprehensive Plan gives elevations from 1,330 feet near Mendota to 5,524 feet at Whitetop Mountain, the second highest peak in Virginia, so the same county contains ground on both sides of the 4,000-foot threshold - which almost no other Virginia county does. One live statewide complication is worth knowing before a designer starts: the snow figures printed in the 2021 Virginia Construction Code are the older ASCE 7-16 maps while the state intended ASCE 7-22, and several large Virginia building departments have issued formal policies forbidding a designer from mixing the two, noting the mismatch can under-estimate ground snow by around 25 psf. In snow country with no published county figure, that is not a detail.
Can my shop with living quarters be an accessory building?
Not in Washington County, and the ordinance is unusually direct about it. Section 66-1 defines an accessory building as a subordinate structure incidental to the main structure, and adds that no such accessory structure shall be used for housekeeping purposes. The same section defines a dwelling unit as one or more rooms designed for living or sleeping and having at least one kitchen. So the moment a detached shop gets a kitchen and a bed it stops being an accessory building and becomes a dwelling - which matters because accessory structures may come within five feet of a property line while a main structure in A-1 needs 15-foot side yards totalling 50 feet, a 35-foot rear yard and a 35-foot street setback. There is a cleaner route, and it is the one most barndominiums take anyway: section 66-297 says garages, carports, porches and stoops attached to the main building are considered part of the main building. An attached shop is simply part of the house, measured as one building. If the plan is genuinely a second structure on a lot that already has a house, that is a second dwelling unit and has to be tested as one - A-1 permits single-family and two-family dwellings, and a two-family dwelling is one structure with two units, not two structures. One more trap sits in A-2, the district nearer the towns: section 66-328 requires all accessory buildings to be lower than the main building, and caps any accessory building within 20 feet of a lot line at one storey. A tall detached shop beside a single-storey house does not work there.
How big does the lot have to be, and what does the permit cost?
In A-1 Agricultural, Limited - the district most rural acreage here sits in - the minimum lot is two acres, or one acre where public water is available, with 150 feet of frontage at the setback line, a 35-foot setback from a right-of-way 50 feet or wider, side yards of 15 feet each that must total 50 feet between them, and a 35-foot rear yard. Read the side-yard rule carefully before laying out a wide building: 15 and 15 does not satisfy it, so one side has to give up 35 feet. A-2 Agricultural, General, which surrounds the residential areas, drops to one acre with no public utilities, 30,000 square feet with public water and 15,000 square feet with public water and sewer. On fees, the county charges on a sliding valuation scale - in the 100,001 to 500,000 band it is 370 dollars for the first 100,000 plus 2 dollars for each additional 1,000 - and adds a 2 percent state housing levy on every permit plus a 5 dollar zoning permit fee collected alongside. Abingdon charges differently: 25 dollars base plus 5 dollars per 1,000 of value, capped at 35,000. On those published schedules a 300,000 dollar valuation is 785.40 dollars in the county and 1,525 dollars in the town. Both punish starting early - the county adds a review fee equal to the entire permit fee on top of it, and Abingdon doubles the fee outright. Valuation is material plus labour, based on the contract price, or on fair market rate where the owner is doing the work, and the Building Official may verify material costs.
Can I live in an RV on the land while the barndominium goes up?
Yes, with a clock on it. Section 66-205 allows one camper trailer, recreational vehicle or manufactured home to sit on the same lot as the permanent dwelling under construction, in districts where manufactured homes are a permitted use without a special exception, and the county publishes a dedicated RV application form for it. The temporary dwelling has to be removed within 30 days of the certificate of occupancy for the permanent dwelling, and in any case no later than 18 months after the building permit was issued - or 90 days after the certificate where the permanent dwelling is itself a manufactured or modular home. Two other timing rules are worth planning around. A zoning permit must be obtained before anything is started, reconstructed, enlarged or altered, and the certificate of occupancy is applied for at the same time as that zoning permit, then issued within ten days of the work conforming. And a permit will not be issued at all on a parcel the zoning office treats as nonconforming until the division, boundary adjustment or consolidation behind it has been approved - which is a common surprise on family land that was split informally years ago.
