Botetourt County

The Botetourt County Department of Community Development is the sole permitting authority for building permits, zoning permits, and Special Use Permits on parcels within the unincorporated county (i.e., parcels outside the corporate limits of the Town of Buchanan, Town of Fincastle, and Town of Troutville). Botetourt County comprises approximately 544 square miles of Blue Ridge foothill and James River valley territory in western Virginia, forming the northern tier of the Roanoke Metropolitan Statistical Area. The county is rural-to-suburban in character, with the highest-growth populated areas concentrated in the US-220 / US-11 / I-81 corridor south of Fincastle — unincorporated communities including Daleville, Cloverdale, Blue Ridge, Troutville (just outside the town), and the Greenfield / Exit 150 commerce park area. The county seat, Fincastle, is a small incorporated town of roughly 340 residents; the Town of Buchanan sits on the James River at the northern end of the county; the Town of Troutville sits along US-11 just south of Fincastle. All other populated places (Daleville, Cloverdale, Eagle Rock, Blue Ridge, Oriskany, Glen Wilton, Springwood, Lithia, Colon, etc.) are unincorporated communities permitted by the county. For an ADU-style project in the unincorporated county, the typical sequence is: (a) zoning determination by the Department of Community Development (by-right accessory use, family/kinship dwelling, Special Use Permit required, or prohibited); (b) if SUP required, application to the Planning Commission and Board of Supervisors; (c) building permit application to the county building official; (d) inspections through construction; (e) certificate of occupancy. Applicants should expect a substantially longer timeline if an SUP is required, because the SUP process is a public-hearing process with statutory notice requirements under Va. Code § 15.2-2285.

Process overview: Botetourt County's ADU-style permitting process varies by project pathway: (1) Family/kinship dwelling — if the second dwelling is occupied by a family member of the primary-dwelling occupant and qualifies under the county's family/kinship provisions in the zoning ordinance, the zoning administrator may issue an administrative zoning approval, followed by a standard building permit; this is the fastest path when eligible, typically 4-8 weeks end-to-end assuming no building-code complications. (2) Special Use Permit for a rental or non-kin second dwelling — the applicant submits a completed SUP application with site plan, statement of use, and the required filing fee to the Department of Community Development. Staff conducts a zoning analysis and prepares a staff report. The Planning Commission holds a public hearing (advertised per Va. Code § 15.2-2204: once a week for two successive weeks, with final notice not less than five days before the hearing) and makes a recommendation. The Board of Supervisors then holds its own public hearing and votes. The entire SUP process typically takes 60-120 days from complete submission to Board decision; complex applications or those requiring ordinance interpretation can take longer. (3) Minor subdivision — if the applicant prefers to create a separate buildable lot and construct a fully separate dwelling, the subdivision ordinance applies. Subdivision review runs through the subdivision agent and the Planning Commission; timelines vary from 30 days (simple minor subdivision meeting all standards) to 6+ months (major subdivision requiring road approval, stormwater, etc.). Building permits for a second dwelling require compliance with the Virginia Uniform Statewide Building Code (USBC), which is the single statewide building code for Virginia localities; no local building-code amendments supersede the USBC. Well and septic approval (for unincorporated parcels not served by public utilities) is administered by the Virginia Department of Health (Roanoke City and Alleghany Health Districts serve parts of Botetourt County; Central Shenandoah Health District covers the Alleghany-adjacent portions — applicants should confirm the applicable health-district office with county staff) and is required before a building permit can be issued for a dwelling not connected to public water/sewer.

Impact fees: Virginia localities generally do not levy impact fees of the type used in California or Florida; Virginia Code does not broadly authorize impact fees for counties outside certain narrowly enumerated categories. Road impact fees under Va. Code § 15.2-2317 through § 15.2-2327 are available only to counties meeting specific growth-rate and density criteria, and Botetourt County is not on the list of eligible road-impact-fee counties as of 2026-04-21. Cash proffers tied to rezoning applications were formerly common but are now constrained by Va. Code § 15.2-2303.4 (2016) which limits residential proffers. For an ADU built on an existing parcel without rezoning, the applicant pays building-permit fees (set by the county by ordinance and keyed to project valuation), the SUP application fee if applicable (typically several hundred to low four figures for residential SUPs), connection or tap fees for water/sewer if served by a public utility (the Western Virginia Water Authority serves portions of the county), and state and local permit surcharges. Applicants should request a current fee schedule from the Department of Community Development at application time. (schedule)

Botetourt County real property is assessed by the Botetourt County Real Estate Assessment Office; tax administration and personal-property taxation are handled by the Botetourt County Commissioner of the Revenue, and collection by the Botetourt County Treasurer. Virginia law requires general reassessment of real property at least once every four years for most counties (Va. Code § 58.1-3252), with more frequent cycles permitted; Botetourt County historically conducts general reassessments on a multi-year cycle set by the Board of Supervisors (the county has used a four-year cycle in recent periods, though the cycle is periodically reviewed). Unlike California's Proposition 13 acquisition-value system, Virginia uses a fair-market-value assessment system: a parcel is assessed at 100% of fair market value as of the effective date of the reassessment, and that value stands until the next general reassessment (subject to supplemental assessment for new construction). When an ADU / accessory dwelling is added to an existing parcel, the new structure is added to the assessment roll at its contributory fair market value; the primary dwelling's assessed value is not automatically re-triggered by the ADU construction itself, but the parcel's overall assessed value rises by the ADU's contributory value. At the next general reassessment, both structures are re-valued at current fair market value together. The property-tax bill equals assessed value times the Board of Supervisors' adopted real-estate tax rate (set annually in the county budget process; Botetourt County's real-estate rate has historically been in the low-$0.70-per-$100 range, subject to annual adjustment and reassessment-year equalization).

Assessment policy: Virginia is a fair-market-value assessment state; a new ADU is added to the assessment roll at its contributory fair market value as a supplemental assessment effective from completion (building permit final inspection) through the balance of the tax year. The primary dwelling's prior assessed value is not automatically reset by the addition of the ADU, but the parcel's total assessed value increases by the ADU's value. At the next general reassessment (the county operates on a multi-year reassessment cycle), both the primary dwelling and the ADU are re-valued at current fair market value. Owners electing to convert existing interior space (e.g., a basement apartment) to a permitted ADU should expect the contributory value to reflect the creation of a second kitchen and second entry and the resulting increase in market-rent potential of the parcel; an owner adding a detached ADU typically sees a larger incremental assessment increase than one converting existing interior space. Property-tax rates are set annually by the Botetourt County Board of Supervisors in the county budget process; owners should confirm the current year's rate from the county's adopted budget because rates change annually and the equalized rate following a reassessment year may differ from the prior-year rate.

Botetourt County administers or is subject to several overlay regimes that materially affect ADU siting on unincorporated parcels: (1) FEMA Special Flood Hazard Areas along the James River (running through Buchanan, Eagle Rock, Springwood, and Glen Wilton), Craig Creek, Catawba Creek, Jennings Creek, Looney Creek, and their tributaries, with NFIP floodplain regulations administered through the county's floodplain ordinance; (2) Blue Ridge Parkway adjacency along the eastern ridge (the Peaks of Otter area and the parkway corridor pass through Botetourt County), with scenic-corridor considerations where the county zoning ordinance applies corridor-overlay protections near the parkway; (3) George Washington & Jefferson National Forest — large portions of the northern and western Botetourt County mountain territory are federal forest land managed by the U.S. Forest Service; federal regulation applies inside the forest boundary, and private parcels adjacent to or in-holding within the forest must contend with fire-management, access, and buffer considerations; (4) Appalachian Trail corridor — the AT crosses Botetourt County in the Fullhardt Knob / Curry Creek / Jennings Creek area, with National Park Service scenic-easement and corridor-management interests that can affect ridgetop and ridgeline-visible development on nearby private parcels; (5) Agricultural and Forestal Districts (AFDs) established under Va. Code § 15.2-4300 et seq., which provide participating landowners use-value taxation and subdivision-deferral protections in exchange for a commitment to keep land in agricultural or forestal use; (6) Chesapeake Bay Preservation Act applicability — Botetourt County is NOT in the Tidewater area covered by the Chesapeake Bay Preservation Act (Va. Code § 62.1-44.15:67 et seq.), so Resource Protection Areas (RPAs) and Resource Management Areas (RMAs) do not apply; (7) wildfire risk — Botetourt County has elevated wildfire exposure in its mountain and national-forest-adjacent areas (tracked by the Virginia Department of Forestry), but Virginia does not have a California-style Very High Fire Hazard Severity Zone regulatory overlay with mandatory ignition-resistant-construction requirements; (8) Karst terrain — significant portions of the James River valley and the limestone belt through Botetourt County exhibit karst geology (sinkholes, caves, springs), which affects septic suitability, foundation engineering, and stormwater infiltration; Virginia Department of Environmental Quality and Department of Conservation and Recreation have karst-protection guidance, and the county requires site-specific geotechnical consideration for structures in mapped karst areas.

• FEMA National Flood Insurance Program — Special Flood Hazard Areas (James River and tributaries) — Botetourt County participates in the National Flood Insurance Program and administers a county floodplain ordinance satisfying the NFIP minimum standards. Principal Special Flood Hazard Area (SFHA) extents in the county run along the James River (which enters the county at Eagle Rock and exits near Buchanan, passing Springwood and Glen Wilton), Craig Creek (draining from Craig County through the western part of the county), Catawba Creek, Jennings Creek, Looney Creek, and various smaller tributaries. An ADU in an SFHA must comply with NFIP elevation requirements (lowest finished floor at or above Base Flood Elevation plus any county freeboard), flood vent requirements on enclosed areas below BFE, anchoring requirements, and post-construction Elevation Certificate filing. Several historic riverfront communities — notably Buchanan and Eagle Rock — have significant SFHA coverage on the older river-adjacent lots, and owners considering ADU additions in these areas should retrieve current-effective FIRM panels early in planning. The Town of Buchanan also participates in NFIP separately for its corporate area.
• Blue Ridge Parkway scenic-corridor adjacency — The Blue Ridge Parkway passes through eastern Botetourt County near the Peaks of Otter area (milepost approximately 83-105 within or adjacent to the county). The Parkway is federal land managed by the National Park Service; NPS regulation applies within the Parkway boundary, not to private parcels outside it. However, Botetourt County zoning has used scenic-corridor or ridgetop-visibility provisions along portions of the Parkway corridor to limit visual impacts on the Parkway viewshed (per NPS cooperative policy with localities along the Parkway), and individual deed restrictions or scenic easements may apply to specific parcels adjacent to the Parkway. Owners of parcels visible from the Parkway should check the zoning overlay (if any) in effect for their specific parcel, any recorded scenic easements, and whether the site falls within an ordinance ridgetop-protection zone before siting a detached ADU on a high-visibility slope or ridgeline.
• George Washington & Jefferson National Forest adjacency and in-holdings — Large portions of western and northern Botetourt County lie within or adjacent to the George Washington & Jefferson National Forest, including the Glenwood-Pedlar Ranger District. National Forest System lands are federally administered; private in-holdings (inholdings) and private parcels adjacent to the forest boundary remain under county zoning but face practical constraints from fire-management activities, access easements across forest land, and forest-boundary fire-buffer best practices. An ADU on a forest-adjacent or in-holding parcel should be sited with consideration of wildfire exposure, forest-road access reliability, and any recorded easements or rights-of-way crossing federal land. Owners should contact the Glenwood-Pedlar Ranger District for in-holding access and fire-management questions.
• Appalachian Trail corridor (National Park Service scenic easement interests) — The Appalachian Trail crosses Botetourt County in the Fullhardt Knob / Curry Creek / Jennings Creek area and continues through the county's ridgelines. The AT corridor is federally protected and administered by the National Park Service, U.S. Forest Service, and the Appalachian Trail Conservancy. Private parcels visible from the AT may be subject to voluntary scenic easements, donated conservation easements, or deed-restriction programs intended to preserve the trail viewshed. A detached ADU sited on a ridgetop or upper slope visible from the AT may face scenic-easement review if the parcel is encumbered; owners should title-check for recorded scenic easements, Appalachian Trail Conservancy interests, or Virginia Outdoors Foundation easements before designing a high-visibility structure.
• Virginia Agricultural and Forestal Districts (local option under state law) — Botetourt County has established Agricultural and Forestal Districts under the state AFD Act. Enrollment is voluntary; participating landowners commit to keeping land in agricultural or forestal use for a period (typically 4-10 years) in exchange for use-value assessment (Va. Code § 58.1-3230 et seq.) and limited protection from certain governmental actions that would disrupt agricultural use. An ADU on an AFD-enrolled parcel is generally permitted if it is an accessory use to continued agricultural operation (e.g., a farm-labor dwelling or family-kinship dwelling), but non-agricultural commercial-rental ADUs may conflict with AFD purposes and trigger AFD advisory-committee review. Owners should consult the Botetourt County AFD Advisory Committee and the zoning administrator before assuming ADU compatibility on AFD-enrolled acreage.
• Karst terrain (sinkholes, caves, springs — James River limestone belt) — The James River valley through Botetourt County and surrounding limestone belts contain significant karst features — sinkholes, caves, losing streams, springs, and shallow bedrock. Karst terrain materially affects ADU siting because (a) conventional onsite septic systems can short-circuit into groundwater via fractures and sinkholes, requiring engineered or alternative onsite sewage systems subject to Virginia Department of Health approval; (b) stormwater management must avoid concentrated infiltration into open sinkholes; (c) foundation engineering for slab or crawl construction may require geotechnical investigation if shallow bedrock, solution cavities, or sinkhole-collapse risk is present; (d) structural setbacks from mapped sinkholes are commonly required by the county. Owners in the karst belt should plan for additional geotechnical and environmental-health review relative to non-karst Virginia sites.
• Virginia Department of Forestry wildfire risk and Virginia Statewide Building Code WUI provisions — Botetourt County has elevated wildfire exposure in its mountain and national-forest-adjacent areas, where the Virginia Department of Forestry tracks wildfire risk using statewide risk-assessment methodology. Unlike California, Virginia does not have a statewide Very High Fire Hazard Severity Zone overlay that mandates WUI-rated construction materials on a per-parcel basis. The Virginia Department of Forestry publishes wildfire risk assessments and promotes defensible-space practices, but enforcement is advisory rather than regulatory. The Virginia Uniform Statewide Building Code, which is the single statewide building code (localities cannot impose more stringent building standards), has not statewide-adopted the International Wildland-Urban Interface Code. Owners in wildfire-exposed Botetourt County locations (especially national-forest-adjacent and Blue Ridge Parkway-adjacent parcels) should follow defensible-space best practices but face no locality-imposed WUI construction overlay analogous to California Chapter 7A.
