Albemarle County One statewide code, no local amendments

Barndominium Builders in Albemarle County, VA

Albemarle County wraps the independent city of Charlottesville entirely, and because a Virginia independent city sits in no county at all, the county has no authority inside the city limits and the city has none outside them. All of the land is on the county side: 167,583 acres in farms across 720 square miles, against ten square miles of city. What makes building here unlike anywhere else in Virginia is not the ground, which is good, but the ordinance. County Code § 18-4.2 defines a "building site" that may not contain any slope of 25 percent or greater, and then requires every structure needing a state building permit to sit inside it — so twenty acres in Albemarle is not twenty acres of building envelope.

Building conditions in Albemarle 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.

Critical slopes are removed from the buildable area, not just conditioned

County Code § 18-3.1 defines critical slopes as "slopes, other than managed or preserved slopes, of 25 percent or greater." § 18-4.2.1(a) then says a building site "may not contain any area of land that is: (i) in critical or preserved slopes," nor in the flood hazard overlay, under water, within 200 horizontal feet of the 100-year flood plain of a public water supply reservoir, or in a Chapter 17 stream buffer. § 18-4.2.3 applies that "to the location of any structure for which a permit is required under the Uniform Statewide Building Code." Most steep-slope rules make you engineer for the grade; this one takes the ground out of the envelope first.

Albemarle County Code §§ 18-3.1, 18-4.2.1, 18-4.2.3, codified through Ord. No. 25-2(2) enacted 18 June 2026 (Supp. No. 6, Update 1), read via api.municode.com product 12230 / job 496282, 2 Sep 2026

A dwelling needs 30,000 contiguous square feet, shaped no worse than 5:1

§ 18-4.2.2(a)(1): a building site for a dwelling not on public or central sewage "shall have an area of 30,000 square feet or greater and shall be of such dimensions that no one dimension exceeds any other by a ratio of more than five to one as described by a rectangle inscribed within the building site," with "adequate area for locating two subsurface drainfields approved by the Virginia Department of Health." That is 0.689 of an acre, contiguous, clear of all five exclusions, and it cannot be assembled as a ribbon of bench land between two ravines. A conforming two-acre RA lot can still have no lawful building site.

Albemarle County Code § 18-4.2.2(a)(1) (§ 20-4.2.2, 10 Dec 1980; Ord. 12-18(4), 11 Jul 2012; Ord. 21-18(5), 1 Dec 2021), read via api.municode.com, 2 Sep 2026

Rural Areas zoning: two acres, a 75-foot front setback and a 35-foot height cap

The RA district area and bulk table at § 18-10.4 sets gross density at 0.5 dwelling units per acre, minimum lot size 2.0 acres, minimum frontage 250 feet on an existing public road or 150 feet internal, front yard 75 feet on an existing public road or 25 feet internal, side 25 feet, rear 35 feet, and maximum structure height 35 feet. Detached single-family dwellings and accessory buildings including storage buildings are permitted by right under § 18-10.2.1, so the building type itself needs no special use permit — the constraints are all siting, area and bulk.

Albemarle County Code §§ 18-10.2.1, 18-10.4 (§ 20-10.4, 10 Dec 1980; 14 Aug 1985; Ord. 08-18(7), 12 Nov 2008), read via api.municode.com, 2 Sep 2026

The county permits everywhere, including inside its only town

County Code § 5-102 establishes a Building Inspection Office in the Department of Community Development and makes it "the local building department as that term is used in the Building Code," with the Building Official appointed by the County Executive under § 5-103. Scottsville is the only incorporated town in Albemarle, and its own code settles the question rather than leaving it to population: Town Code § 22-4 reads, in full, "The Uniform Statewide Building Code shall be enforced by the county." The town keeps its own zoning appendix, so inside the town limits the county issues the building permit and the town administers zoning.

Albemarle County Code §§ 5-101 to 5-103 (Ord. 18-5(1), 14 Mar 2018); Town of Scottsville Code §§ 22-2, 22-4, recodification adopted 17 Oct 2022, read via api.municode.com products 12230 and 12984, 2 Sep 2026

On a lot under 21 acres the well is drilled before the building permit issues

County Code § 17-1000 requires a Tier 1 groundwater assessment "prior to the issuance of a building permit for a new structure on a lot of record less than 21 acres in size" that will be served by an individual well. § 17-1001 defines that assessment as "the owner drilling a well on the lot" and filing the Virginia well drilling completion report (form GW-2) plus the well's latitude and longitude, which "must be accepted as complete and accurate by the administrator prior to issuance of the building permit." The published Tier 1 fee is $60. It is a sequencing rule, and it puts the drilling rig ahead of the permit.

Albemarle County Code §§ 17-1000, 17-1001, 17-1005 (Ord. 04-17(1), 8 Dec 2004, effective 8 Feb 2005; Ord. 14-17(1), 7 May 2014); fee at County Code § 1-504 (Ord. 23-1(1), 6 Dec 2023), read via api.municode.com, 2 Sep 2026

Building permit fees are flat bands by square footage, plus 4 percent

County Code § 1-501(B) prices a new single-family dwelling in six steps: $500 under 1,500 sq ft, $1,000 for 1,501-2,500, $1,500 for 2,501-3,500, $2,000 for 3,501-4,500, $3,000 for 4,501-7,500 and $4,000 above 7,500. A detached shop is billed separately as a Residential Accessory Structure at $0.18 per square foot on gross finished area, minimum $35. Residential plan review runs $0.05 per square foot, minimum $10. A 4 percent technology surcharge is added to each fee under § 1-505, and reinspections after the second inspection of the same work are $100 each.

Albemarle County Code §§ 1-501(B), 1-505 (Ord. 23-1(1), 6 Dec 2023; the amounts moved out of Chapter 5 by Ord. 23-5(1), 6 Dec 2023, effective 1 July 2024), read via api.municode.com, 2 Sep 2026

Also worth knowing before you build in Albemarle County

Living quarters in a freestanding shop are expressly prohibited: § 18-5.1.34(a): "An accessory apartment shall be permitted only within the structure of the main dwelling to which it is accessory. Usage of freestanding garage or other accessory structure for an accessory apartment is expressly prohibited." Not more than one per single-family detached dwelling, capped at 35 percent of the structure's gross floor area, with three off-street parking spaces. So a barndominium whose shop and living space share one building is simply a detached single-family dwelling, permitted by right in RA. Putting a second living unit in a separate shop beside an existing house is not an accessory apartment at all — it is a second dwelling unit, and it consumes one of the parcel's finite development rights under §§ 18-10.3.1 and 18-10.3.2.
Two slope regimes, and rural land gets the stricter one: § 18-30.7.1 establishes the Steep Slopes Overlay District "on those lands within the development areas of the county as delineated in the comprehensive plan," and § 18-30.7.2 provides that within the overlay "the regulations in this chapter pertaining to critical slopes shall not apply." The county's own comprehensive plan page puts the Development Areas at "about 5 percent of the County's land." So the managed-versus-preserved machinery that every summary of Albemarle's slope rules leads with is the urban ring's rule. On the other 95 percent, where the farm acreage is, § 18-4.2 governs — and § 18-4.2 is the one that subtracts the ground rather than conditioning it.
The easier slope waiver is closed to rural land: Any § 18-4.2 requirement can be waived by special exception of the Board of Supervisors under § 18-33.5, on findings that include the county engineer's determination on erosion, stormwater, siltation and septic-effluent travel, assessed against the VDOT Drainage Manual and the Virginia Erosion and Sediment Control Handbook. The published Special Exception fee is $980. The shorter criteria-based route at § 18-4.2.5(b) is available only "on any parcel not within the Rural Areas (RA), Monticello Historic District (MHD) or Village Residential (VR) zoning districts" - which excludes almost all of the county's buildable land by its own terms.
Every drainfield is sized for three bedrooms, whatever gets built: § 18-4.1(b)(2): no building permit issues on a conventional onsite sewage system without Virginia Department of Health approval of "both an original and a replacement subsurface drainfield," and "for residential uses, each subsurface drainfield shall have suitable soils of adequate area to accommodate sewage disposal from a three bedroom dwelling." Against the state sizing table of 150 gallons per day per bedroom, that is 450 gallons per day of proven soil capacity, twice over, even for a one-bedroom barndominium. § 18-4.2.4 adds that any onsite sewage system "shall be located within a building site" and that VDH should be mindful of the intent "to discourage onsite sewage systems on slopes of 20 percent or greater" - a shallower threshold than the 25 percent that excludes structures.
On rural land the stream buffer follows intermittent streams too: County Code § 17-600(A) sets a 100-foot buffer each side of a perennial stream inside the Development Areas. § 17-600(B), for "a water supply protection area or other rural land," extends it to "perennial or intermittent streams, contiguous nontidal wetlands, and floodplains," at whichever is wider of 100 feet each side or the limits of the floodplain, and "no less than 200 horizontal feet wide from the floodplain of any public water supply impoundment." Under § 18-4.2.1(a)(v) that buffer is subtracted from the building site, so a wet-weather drainage that is dry all August still projects a 200-foot non-buildable corridor across the parcel. Albemarle is not a Chesapeake Bay Preservation Act locality, and it built the equivalent anyway.
The county publishes no Table R301.2 figures of its own: The 2021 Virginia Residential Code prints Table R301.2 blank, with the instruction that the criteria "shall be established by the local jurisdiction." Albemarle's Building Regulations and Code page, its Building Permits page and its Building Inspections page were each read in full and none states a ground snow load, design wind speed, seismic design category, frost depth or winter design temperature. What is fixed statewide still applies: a 12-inch minimum footing depth below undisturbed ground under VRC R403.1.4, IECC climate zone 4A for the county, a 5 ACH50 blower-door limit, and R-15 or R-13+1 walls. The rest is settled in writing with the county building official before a frame is ordered.
Virginia's own expansive-soils list does not name this county: Virginia Energy's Expansive Soils page names "the Coastal Plain, the Shenandoah Valley, and the Mesozoic basins around Culpeper, Farmville, Danville, and Richmond" as the areas most likely to have expansive or frost-heave-susceptible soils, and Albemarle is in none of them. The same page adds the caution that matters more on a wide, light, slab-heavy building than on a house: "Heavy loads such as chimneys resist uplift, while lighter loads such as concrete patios cannot, leading to differential settling," and "standard homeowner's insurance does not cover damage from expansive/compressive soils or frost heave." The state's own caveat is that distribution "can only be approximated from current soil maps, and field visits to specific areas are necessary."
167,583 acres in farms, and a median farm of 60 acres: Albemarle covers 720.5 square miles and carries 167,583 acres in farms across 866 operations, 35.8 percent of its land area, with 60,438 acres of woodland inside those farms and 396 operations under 50 acres. The median farm is 60 acres. Population reached 118,356 in mid-2025, up 5.1 percent from the 2020 census. That is the eighth-largest farm acreage of any Virginia county and a real supply of small tracts - which is exactly why the constraint here is the ordinance rather than the ground.

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.

What a build looks like

Three stages every Albemarle County project passes through, from a raw parcel to a finished home. Site work first, because that is where the budget is decided.

Stage one

The parcel

Zoning, setbacks, flood zone and utility access get checked before anything is drawn.

Stage two

Pad and permit

Clearing, grading and a compacted pad, while the submittal works through whichever office issues the permit where you are building.

Stage three

Frame to finish

Shell erected and dried in, then systems, insulation and interior finish through to CO.

Those are the rules where you are building in Albemarle County. Tell us what you want to build and we will draw it to them.

Where we build around Albemarle County

Albemarle County and the rural land around it. The buildable acreage for a project this size usually sits outside the city limits, which is frequently what changes who issues your permit.

The Albemarle County service area, including the rural acreage outside the built-up edge, which is where the parcels big enough for a build like this usually sit. The map marks the territory we build in. It is not a branch location, and there is no office at this pin.

Building in Albemarle County: common questions

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

Start your project

Charlottesville is right there. Do I deal with the city or the county?

The county, unless your land is inside the city limits, in which case none of this applies. Charlottesville is one of Virginia's 38 independent cities, which means it belongs to no county at all: Albemarle has no building official, no zoning administrator and no board of supervisors with any authority inside the city line, and the city has none outside it. In practice the question rarely arises, because Charlottesville is 10.2 square miles against Albemarle's 720.5 and essentially all of the buildable land is on the county side. The one wrinkle worth knowing is that Albemarle's Community Development office has a Charlottesville mailing address at 401 McIntire Road. That is a county department with a city postcode, not a shared jurisdiction.

I have twenty acres. Can I put the building where I want?

Almost certainly not, and this is the thing about Albemarle that surprises people who have built elsewhere in Virginia. County Code § 18-4.2 defines a "building site" and says it "may not contain any area of land that is: (i) in critical or preserved slopes" - meaning 25 percent or steeper - nor in the flood hazard overlay, under water, within 200 horizontal feet of the 100-year flood plain of a public water supply reservoir, or in a Chapter 17 stream buffer. Then § 18-4.2.3 requires that any structure needing a state building permit be located inside that site. So the buildable envelope is what survives five subtractions, and on rolling foothill ground it is often a fraction of the deed acreage. The site also has to be at least 30,000 contiguous square feet, in a shape no more elongated than five to one, with room for two health-department-approved drainfields. Walk the parcel with a topographic map before you sign, not after.

What if the only good spot on my land is on a slope?

There is a route, and it goes to the Board of Supervisors. Any requirement of § 18-4.2 can be waived or modified by special exception under § 18-33.5. The application has to state how it meets one of four findings, and the county engineer has to determine that soil erosion, sedimentation, water pollution and septic-effluent travel will be mitigated, assessed against the VDOT Drainage Manual and the Virginia Erosion and Sediment Control Handbook. The published fee is $980 plus the county's 4 percent surcharge, and it is a public-hearing item rather than a counter transaction. Note that the shorter criteria-based waiver at § 18-4.2.5(b) is written to exclude parcels in the Rural Areas district, so rural land only has the full special exception. There is also a narrow exemption at § 18-4.2.6(b) for the first single-family dwelling on an old lot of record, but read its proviso: if the parcel does contain adequate ground outside the critical slopes, the dwelling still may not sit on the slope, and the exemption does not reach a detached shop at all.

Can I build the shop first and live in it while the house goes up?

Not as a separate building. Albemarle's § 18-5.1.34 is unusually blunt: an accessory apartment "shall be permitted only within the structure of the main dwelling to which it is accessory. Usage of freestanding garage or other accessory structure for an accessory apartment is expressly prohibited." A barndominium where the shop and the living space share one roof is simply a detached single-family dwelling, permitted by right in the Rural Areas district, and none of that is a problem. Living quarters in a standalone shop beside a house is a second dwelling unit, which has to consume one of the parcel's finite development rights under §§ 18-10.3.1 and 18-10.3.2 - and a parcel created as a 21-acre-or-larger by-right division carries exactly one. The farm-building exemption does not rescue it either: Va. Code § 36-97 defines a farm building as one "not used for residential purposes," so the moment anyone sleeps in it the full state building code applies.

What does Albemarle publish for wind speed, snow load and frost depth?

Nothing, and that is a real answer rather than a gap. The 2021 Virginia Residential Code prints Table R301.2 blank in every cell with the instruction that the criteria "shall be established by the local jurisdiction," so those numbers are each locality's own to publish. Albemarle's building code page, its building permit page and its inspections page were each read through and none carries a ground snow load, design wind speed, seismic design category or frost depth. What is fixed statewide still binds: a 12-inch minimum footing depth below undisturbed ground under VRC R403.1.4, IECC climate zone 4A, a 5 air-changes-per-hour blower-door limit at 50 pascals, and R-15 or R-13-plus-1 walls. Anything beyond that gets settled in writing with the county building official before the frame is ordered. Be wary of any builder who quotes you a design wind speed for Albemarle - no authority in the county has published one.

Well and septic - what is the order of operations?

Water first, and earlier than most people expect. Outside the Albemarle County Service Authority's service areas you are on a well and a drainfield, and County Code § 17-1000 requires a Tier 1 groundwater assessment before a building permit issues for a new structure on a lot of record under 21 acres served by an individual well. § 17-1001 spells out what that means: drill the well, file the Virginia GW-2 completion report with the well's coordinates, and have the county accept it. The fee is $60. On the septic side, § 18-4.1(b)(2) blocks the building permit until the Virginia Department of Health has approved both an original and a replacement drainfield, each sized for a three-bedroom dwelling regardless of how many bedrooms you actually build - which at the state rate of 150 gallons per day per bedroom means 450 gallons per day of proven soil, twice. Both drainfields have to sit inside the same building site as the house, and § 18-4.2.4 records the county's intent to discourage onsite systems on slopes of 20 percent or greater. VDH runs this through its Blue Ridge Health District office in Charlottesville.

Is the Central Virginia earthquake zone something I need to design for?

For a detached house, almost certainly not. Albemarle does sit in the Central Virginia Seismic Zone, and the 2011 magnitude 5.8 Mineral earthquake was felt hard here, so the question is a fair one. But VRC R301.2.2 exempts detached one- and two-family dwellings from the code's seismic provisions until seismic design category D0, and Louisa County - the locality the 2011 epicentre actually sat in - publishes category B, two full steps below that threshold. Albemarle publishes no category of its own, so no number should be quoted for it either way. Steel and post-frame buildings are light and ductile, which is the favourable end of the seismic question anyway. The hazards worth spending money on in this county are slope, stormwater and drainfield soil, in that order.

Building in Albemarle County?

Start with the plan. Tell us what you want to build and we will draw it, then confirm which office issues the permit for your parcel, what it will let you put there, and what wind load it has to meet. That conversation costs nothing.
